Modern electrical components play a major role in helping people develop more efficient and powerful cars than they have been able to do in the past couple of decades. A lot of automotive innovations have a something to do with integrating complex electrical systems into our day to day vehicles, thus rendering them more efficient at all operating conditions, regardless of the external environment and other factors.
Knowing about a car batteries cairns and electronic components might be a little of a stretch for most people. Nevertheless, it might be beneficial when you need to get some repairs done, as you will then understand what actually has gone wrong in your vehicle. It can also help you when sourcing replacement components, as otherwise you would have to completely rely on a mechanic.
Modern cars do have a lot of different systems, which vary depending on the vehicle model, brand and year of manufacturing, but they all have the following basic components which are similar in most aspects:
- Battery – A vehicle’s battery is the source of energy for the entirety of the electrical components themselves. It basically provided the required power to the ignition switch to start up your car and additional current to other vehicle components when the alternator fails to keep up with the added loads. A variety of normal and deep cycle batteries for sale can be found in shops, but not all are compatible with each vehicle type.
- Alternator – You may have wondered what this is while reading about the battery’s function above. The alternator is what keeps your battery charged up at all times, and is the main source of power for the electrical systems while the engine is running (as it only works by drawing power directly from the engine itself). It is a good idea to always get your alternator inspected along with your car battery, to assess whether either of them is faulty. You can easily do this by contacting a specialist in repairing batteries in Cairns or any other major city in your area.
- Ignition Coil – This component is used to fire up your engine by drawing current from the car’s battery in petrol engines. What they do is generate a high voltage spark that can ignite the fuel-air mixture inside the cylinders. This is done by converting the relatively low voltage of the battery (12V) into the very high values (between 20000V and 50000V) needed to produce a spark.
- Fuel Pump Switch – Unlike petrol engines, diesel engines do not require a spark plug to ignite the fuel-air mixture. Therefore, they don’t need an ignition coil to keep the engine running, instead relying on a fuel pump solenoid switch to properly supply the required amount of fuel for optimum engine operation.
- ECU – The ECU (Electronic Control Unit) is responsible for maintaining correct values of fuel and air to inject to the cylinder, as well as vary the operation of various engine parts according to the inputs given by the driver and other external factors. Simply put, it is a type of computer that is responsible for adjusting all the variables and coordinating engine operations to improve efficiency.
