BMW Parts and Accessories

In this article I will tell you about different parts and accessories used in cars and more particularly I will focus your attention on BMW.

Let us begin now with the fuel injectors. They are in fact linked to the electronic controls and these controls together with a good clean fuel are the two important things you need to look for when pursuing a good and precise work of your fuel injectors.

Fuel injectors are made for both – to make horsepower and to keep the emissions low. In order for this to work a good rapid burn of the fuel is required. That’s why BMW are so successful here. They made a small needle-like valve that forcefully under big pressure injects the fuel into the intake port. The fuel is atomized and like this together with the oxygen in the air it burns instantly and this gives the needed power for your BMW car.

The clean fuel is very important because it will give a longer life for your BMW car and that’s why you need to take really good care of your oil filters. There are usually two types of oil filters - cartridge and spin-on. Sometimes a magnetic system is applied to the filter in order for the ferromagnetic parts to be captured.

Another very important part of your BMW car is the thermostat. This device is capable of both - measuring and regulating the temperature in the car. If it fails your engine may damage because it will most likely overheat. In order to control the temperature the thermostat will constantly measure it and then it will cool down the system or heat it up by switching and controlling the flow of the heat energy.

Now let’s discuss the BMW oxygen sensor. This is a system with a measuring device putted in the exhaust. It is important to know how well the fuel has burned in the engine and this measuring device will provide you with that data. This data will be then examined by the fuel injection computer and it will make the necessary adjustments in order for the better burn of the fuel. These adjustments are all about the way in which the fuel combines with the air and more precisely – the oxygen in that air. This is very important because the better the fuel burns the higher is the performance of your BMW car.

The BMW ignition coil is another amazing thing – it will not fail for very long time and now let’s see why it is so important. In order for your BMW car to start operating it needs a provider of a little spark which will ignite the combined with oxygen fuel. This spark in your BMW car is provided by the spark plugs but they need a high-voltage electrical charge and this will be provided to them by the ignition coil.

The ignition coil is based on induction. It will take power from the accumulator which is 12 volts and then it will transform it to thousands of volts because in order for the spark to be created this high voltage is an indispensability.

The BMW power steering pump on the other hand is the device which will transform the power from the engine into hydraulic pressure. This hydraulic pressure will enable you to easily turn the wheel in the desired direction. Basically the system is driven by the engine which will generate pressure in a rotary-vane pump and the faster your vehicle is going the more pressure is generated. Of course there is also a valve which will relief the system if the pressure goes too high. This valve prevents from damages and also it controls the pressure to be in the necessary values that are still big enough for the system to work properly.

We were talking about some high voltage and now let us discuss for a moment how this high voltage is distributed to for example – your ignition system. If your BMW car is old enough you will see that it uses a BMW distributor cap. This cap is usually plastic and it is used to wire up devices and insure a way for the high voltage to safely pass through. Of course there are many problems that can surely damage your BMW car and for example the first major problem is the water. As you may know the water conducts electricity well enough especially when the voltage of that electricity is high enough. This in our case is really bad because you have to be very careful not to allow any water to go even near the distributor cap.

You will see that with time some cracks begin to occur on every plastic material especially if the temperature of it is changing. If you see cracks on your distributor cap you will need to change it. This is easy and you can do it yourself. However because of these problems with the cap you may want to get a BMW car with DIS or distributorless ignition systems. The only problem there will be that they are a bit more complicated and you will most likely be unable to change it yourself if you are not an expert.

Now let’s dive in some mechanics. Vibrations when big enough can cause some problems with your BMW car and will surely make you feel not at ease. To prevent this your BMW car is equipped with coil springs which in fact are known to be the reason for the good suspension of the BMW cars but in fact it is not the only reason. The coil springs are controlled by the BMW shocks and the precise tuning of these shocks is the very thing that will provide the best suspension. This is why the tuning for every particular vehicle is a must and BMW defiantly knows that and perhaps this is why they are known well for their good suspension. In order to understand why suspension is so important just imagine how much time will be needed for your BMW car to settle down after you hit a bump and even without taking in account the damages that may happen you will defiantly won’t feel good if these high vibrations occurs constantly.
