Car Battery For Beginners

[ad_1]

The car battery is what powers all the electrical components of the car. It is typically a rechargeable 12 volt lead-acid battery that powers the electrical system in the vehicle. This means that there are various chemicals in the battery that goes into a reaction when it is in use. When it is recharging, the chemical reactions are reversed.

Car Battery Components

The main components of the car battery is that it starts the starter motor and the ignition system. The starter motor is basically an electric motor that gets the main gas engine going. The ignition system is what ignites the mix of gas and air to produce the combustion the engine needs to keep it running.

Everyone knows that when the car battery dies, you can’t start it anymore. There can be many reasons a car won’t start, but when you hear that clicking noise, and no ignition, than it is probably a dead battery. The clicking noise is telling you that you starter is working, but it’s not engaging the battery. When the starter is dead, you won’t here a clicking noise.

The car battery also runs the electrical system of the car. The main component to the electrical system are the lights. The headlights, interior lights, trunk light, and the dashboard light are all powered by this 12 volt battery. That is why when you leave the lights on, the battery drains and you can’t get the car started.

So the next question is, how come the car battery drains so quickly that you can’t start the car, when you leave the lights on, but it can power the lights for a seemingly unlimited amount of time while you’re running the engine? The first part of the answer is that it takes close to a full 12 volts to start your car. So if you’re battery is at 11.2 volts, sorry but you’re probably out of luck. The second part of that has to do with how it recharges itself as it runs.

How It Recharges

You car has something called the alternator. This takes the mechanical motion of the engine, via alternator belt, and produces electricity to recharge the battery. It’s like a give and take relationship. The car battery starts the engine, which in turn recharges it back up as it runs on gasoline. That’s why after you jump start a car, you should probably run it for a while before you shut it off again.

There is a little computer attached to the alternator that tells it to charge or stop charging the battery. That’s a great little thing to have working because if you overcharge the battery, you can create hydrogen and that can cause the battery to explode.

So why then do you have to buy a new car battery every so often? Well, because the batteries tend to not hold the charge as much as time goes by. Most 12 volt batteries actually hold close to 13 volts. A mechanic once told me that they call it 12 volt batteries because 13 is an unlucky number. I don’t know if that’s an urban legend or not. But either way, it holds more than 12 volts. Then over time it starts to fade. And when it can’t hold much more than 12 volts anymore, than it’s time to get a new battery.

Advantages and Disadvantages of Magnetic Bearings

[ad_1]

With the development of various industries, bearing product plays a more and more crucial part. A bearing can be defined as a member specifically designer to support moving machine components. It is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. The use of bearings is essential to all types of machines, in that they provide the function of supporting another piece or component in a desired position. Moreover, they can also be used to supporting a rotating object or shaft.

As we know that bearing types are various, when compared to common types such as ball bearings and roller bearings, the magnetic bearings may not be very popular. They can support a load using magnetic levitation. They can be used in many specific places such as electric power generation, petroleum refining, and natural gas pipelines and so on.

Although magnetic bearings are not as common as some other types, they have their own advantages. First of all, they are free of lubrication which avoids servicing and also enables use in clean room environments. And due to the absence of surface wear, maintenance is also decreased. There could even be no maintenance as long as the control system functions as intended. Secondly, they are contact-free in that the magnetic force is used to support the object as opposed to contact between two surfaces. Thirdly, the magnetic properties of the materials used are highly resistive or immune to changes in temperature, pressure, and the presence of chemicals, therefore, they can be used in highly sensitive applications and in extreme conditions.

Except for those advantages, of course, they also have some disadvantages. For example, their costs are much higher compared to traditional bearings because of the large amount of effort and time required for development and the increase in the number of components. Besides, their complexity is also a disadvantage to use them.

The magnetic force used in magnetic bearings can be divided into two categories of how the force is created: reluctance force and Lorentz force. The former is resulted from a difference of permeabilities between two materials, while the latter is resulted from the movement of charges in a magnetic field. The classical active magnetic bearing and the permanent magnetic bearing both employ the use of the reluctance force in conjunction with ferromagnetic material.

All in all, magnetic bearing is also an important kind of bearing; thus, you should also pay attention to it to learn more about its functions and operations.

What You Should Know About The Acura RSX

[ad_1]

What should you consider about the Acura RSX before you buy one? Any time I buy any new car I always make sure I have done my homework on it first. So if you think the Acura RSX may be the car for you, you should probably do what I do and make sure you know as much about the car as you can find out before you hit the lots. Here is a little bit about what I found regarding the Acura RSX, but do your own research as well so that you know everything about the car the it important to you before you go out and make that purchase. Your best bet, though, is to check out the S type of the Acura RSX.

The Acura RSX is a high performance coupe in the S type. It features a 210 hp 2-liter engine, 6-speed close-ratio manual transmission, modified suspension and brakes, quick-ratio variable rack & pinion steering, upgraded tires, leather interior. Air conditioning and 7-speaker Bose sound system come standard when you buy it new.

Visual inspection of the car reveals that it is best-suited to smaller people. Up front, however, is what counts and there you will probably find the most comfort. The seats of the Acura RSX S Type are fantastic, not racer-tight but with more than suitable grip. The steering wheel is well placed, small, and wrapped with leather. The gear lever falls right to hand and has obviously been placed with care. Also, everything looks great, with typical Acura ergonomics. One drawback would be that the numbers on many of the instruments in the Acura RSX are too small and the indicators on the air controls are not very easy to read. The round air and heat vents are controlled with little clamshell-shaped doors that allow them to almost vanish when closed. Seats and mirrors are heated, while the “set-and-forget” climate control maintains a very nice temperature.

The Acura RSX is casual elegant, but with just a little faux titanium and chrome to dress things up. The sunroof is standard and c

In addition, as you look over more information on the Acura RSX, you will find that there is even more to it. It is a safe car with many standard air bag and brake features that add to the practical appeal. As you look into cars, and if you believe that such a sedan at a these prices may be for you, then you owe it to yourself to give the Acura RSX a chance. Do your research and visit an Acura dealer to take a test drive and see that everything you have read about this sports sedan is true and may just be why the Acura RSX is the right car for you to consider for your next new car purchase.

Why Use Car DVR

[ad_1]

As the technological boom continues it is opening up possibilities in a range of sectors, not least in home and personal security. Cameras have become ever more compact, lightweight, and high quality, meaning that a car DVR is now a viable option for automobile security. A DVR (Digital Video Recorder) is not a new technology, but its compact and high quality nature now brings a new added security to cars.

The obvious reason to use a car DVR system is to keep your automobile safe, with so many different ways your vehicle can come to harm; the DVR is a potent tool. If your car has been hit while you were away from it, you can take a look at the video recording to see exactly what happened, whether it was an accident or not. It would also be possible to take the registration number of any car that had hit you, regardless of whether the driver knew they had or not.

Many automobile owners are the victim of crime, and a car DVR can help to catch anyone who performs a felony against your car. The crime may take the form of simple vandalism, something like running a key down the length of your car, a well-positioned camera would allow you to see and possibly identify the person responsible. Likewise a more serious crime like theft from your car or a stolen car could be recorded by the car DVR, allowing you to positively identify the perpetrator, or at least have the video as evidence.

However, a car owner would rather have no crime committed against them, and the car DVR can be the perfect deterrent to criminals. These days DVR systems for cars are suitably compact, meaning they can typically be hidden somewhere on the car and stay concealed to anyone who does not know they are there. If you want the camera to act as a deterrent, you do not have to reveal it; you simply place a sticker on your car (usually the window) saying that your car is DVR protected. This is usually enough for any potential criminals to not target your car.

The last reason why you should use a car DVR is because it can help in tight parking situations. If you are in the town or city you will know how awkward it can be to park sometimes, the side mirrors are never quite enough to fit into those tight spaces. However if you have a screen in your car it is possible to hook up the DVR system and create a live feed, where a well-positioned camera could aid you in parking.

Castors, Their Elements and Uses Within the Home and Industry

[ad_1]

The following article discusses the elements and uses of adjustable castors, widely used yet rarely mentioned. Found supporting an item of furniture such as a washing machine or settee, a castor provides an easy solution when moving certain pieces. A device not given much thought has become an imperative asset within daily life.

Able to fully rotate the castor permits objects to move easily and turn as required. Wheel axles and bearing races can be altered depending on the use the castor must fulfil and can also be found with rigid housing meaning movement in a single direction, forwards or backwards.

Castors were used as early as the 1500’s on items such as wheel chairs and ‘baby cages’! A ‘baby cage’ was a genuine item used by mothers to keep their children in so they could continue with house hold chores and not have to worry about them escaping or hurting themselves. Castors were installed on the bottom of the cages for easy transportation in and out of rooms. Whilst controversial today, the ‘baby cage’ was an earlier model of the ‘play pen’ many parents utilise in this day and age.

In 1730, castors were made from leather, which was kind to wooden floorings in the home. Leather moved on to brass eventually. Prior to this date hardwood was preferred and as castors were in their early stages of development it took many years to arrive at a perfect material.

Castors have a dominant place within the home and in many a work place. Nylon, rubber, aluminium, cast iron, pneumatic tyred, stainless steel and plastic are just a small portion of the materials available for a successful castor. When choosing it is good to decide using the principle stating that if the wheel diameter is bigger then less resistance the castor needs and this depends on how the castor is required to move.

Lets take a shopping trolley as an example of outdoor use of castors. Without a trolley shopping would be hard work. The castors are fixed in order for the device to move straight ahead, backwards and around corners smoothly providing a solution to thousands of people every day.

Another example shows castors in hospitals. Without these moving patients to the correct wards would prove difficult. Whilst another solution surely would have been invented it goes to show that such a simple item has grown so prominent in every day life. Scaffolders also rely on castors as do refuse collectors when rounding up wheely bins.

Fixing kits are available when buying castors to be added to furniture. A kit consists of nuts, bolts and washers and are available in certain sizes to suit the needs of the item to which a castor will be attached. If the right kit is not used then there is a chance the castor could come loose.

An item which has travelled through time and become prominent has embedded itself into everyone’s lives without realisation yet is something which without we could have very easily been worse off.

How a Tyre Inflator Can Improve Your Fuel Mileage

[ad_1]

Most of us know that driving a car with slightly under or over inflated tyres can cause problems. Wear and tear on a tyre is never a good thing but it can actually be very dangerous. Aside from anything else, you will get more mileage out of your car if you drive on correctly inflated tyres. A tyre inflator is a great thing to have so that you can regularly check and adjust your tyre’s inflation.

Driving on incorrectly inflated tyres can actually cause your car a lot of damage. Tracking and other factors are involved but mainly it’s down to how inflated your tyres are. If they’re under inflated they can easily slide on the road and they can also wear in the wrong places meaning that when your tyres are inflated to the right degree, you have uneven tyre grip.

This can cause real problems and one of the best ways to avoid it is to ensure that you have a tyre inflator with you at all times. Most tyre inflators are easy to use and there are even automatic ones these days which provide you with a quick and easy way to check and inflate your tyres.

One of the main reasons that under inflated tyres cause problems is because the car is designed to drive in a certain way and if this is then off balance because of the tyres, your car will be working harder to drive causing an over use of fuel. If you want to improve your fuel mileage then make sure that you’re always checking your tyre pressures.

A lot of people aren’t aware of the problems that can be caused by incorrectly inflating a tyre. A lot of drivers aren’t even sure how to go about filling a tyre with air. One of the great things about the latest tyre inflators is that they do most of the work for you – you simply plug them in, they fill the tyre and then stop and that’s it.

Overall, keeping a tyre inflator in the car with you is a great way to ensure that you always have the correct tyre pressures. Driving your car with the correct tyre inflation can mean that you save a lot of money on fuel and that your car does more miles to the gallon.

What To Do Immediatley After a Car Accident

[ad_1]

Did you know that there are over six million car accidents in the United States every year? Fortunately, in most cases, car accidents only result in damage in to property but, in one in three cases, auto accidents also result in personal injury.

Even if you have never had an accident before or you don’t drive your car very often, there is always the possibility that you could be involved in an accident through no fault of your own. If you are aware of the steps you should take after an auto accident, you will be better prepared to protect yourself and your passengers from injury and you will be aware of what you need to do protect yourself against unfair claims.

Here are the steps you should take if you are unfortunate enough to be involved in a road accident:

Stop your vehicle

Whenever you are involved in a car accident, however minor, you should always stop. Never leave the scene of an accident without stopping.

Make the Scene Safe

One of the first things you will need to do is make sure that no one has been injured and the scene of the accident is as safe as possible. To avoid the danger of a further collision, place flares or warning lights around the stationary vehicles, and put your hazard warning lights on. If you are on a busy highway, stand well away from fast-moving oncoming traffic.

Call the emergency services

It is advisable to notify the police of an accident, even if there are no serious injuries. If there are any injuries or there is a fire, then the ambulance and fire services should be notified as well. It’s a good idea to notify the police, even if it is a minor accident, because you will need a police report to file with your insurance claim. If possible, the vehicles should not be moved before the police arrive.

Make a complete record of the accident

When the police arrive it is important that give them an accurate record of what has happened. If you are unsure of any of the details, be honest about it, don’t try to speculate or make assumptions. If you are asked if you are injured, it is better to say that you are unsure, rather than to say no, because some injuries from car accidents only manifest themselves later on. If there are any third-party witnesses to the accident, you should ask them to wait for the police to arrive, so that they can give a statement.

Take photographs

If there is damage to your vehicle, then take photographs of that damage. You should also take photographs of any damage to other vehicles as well. If you have any injuries that are visible, take photographs of that too. Sadly, there are people who will claim that far more damage was done to their vehicle than actually was. A photograph will enable you to dispute a spurious claim against your insurance. While making a record of the accident is important, you should not, of course, impede the work of the emergency services and the police while you are doing it.

Exchange details with the other party

If the police attend the scene of a car accident, they will take all the details of those involved in the accident and of any witnesses. If the police do not attend, you should obtain the names and addresses of all those involved, including passenger and witnesses. You should also exchange insurance details with the drivers of the other vehicles involved. If the police are in attendance, the police should provide you with a police report number. With that you will be able to obtain a copy of the police report into the accident. If the accident occurred on a state highway, you are legally required to report the incident to the police.

Get a medical check up

Even if you don’t think that you have been injured, it is advisable to get a medical check-up as soon as possible after a car accident. Injuries caused by car accidents often don’t become noticeable until several days later. Even low-speed impacts can cause spinal damage and, if you felt dazed by the accident, you may have suffered a mild concussion.

Keep all the paperwork

Keep all the paperwork you have relating of the accident in a file. This should include all correspondence, your insurance claim number, details of the claim adjuster dealing with the claim and the names and telephone numbers of all those involved in the case. You should also keep all the receipts for any expenses that you incur as a result of the accident, including car repairs, medical costs and the cost of a rental car if one was needed.

Seek legal advice

It is advisable to contact an attorney straight away when you have had a car accident. A good attorney will help you protect your rights by advising you on how to make sure that evidence is not destroyed and by giving you advice on the preparation of your statement to your insurance company. They will also help make sure that you receive the proper compensation of a car accident and that you receive the best medical treatment.
