The government is making a move on the amount of car emissions which are known contributors to air pollution. The ECU or the Engine Control Units are created.
ECU's are mainly designed to control the engine such that air and fuel mixtures going into the catalytic convert could be be filtered and pollutants passing through the exhaust could be reduced. With this processors, it performs the job with a closed-loop control which generally looks at the system output and input. They are the ones who control the emissions and the economy of the engine. The ECU works with a lot of different sensors which are able to detect everything, from the coolant temperature to the amount of oxygen is in its exhaust. Making calculations that determines the best spark timing and the length of the time fuel injector is open it part of the job of the ECU. Together, these mechanisms allow the car to have lowest emissions and the best mileage.
The ECU processor comes as a module or an ECM (engine control module) that consists of many components, such as analog-to-digital converters, which interpret outputs coming from sensors; high-level digital outputs, which control spark plugs, fuel injector and the cooling fan; digital-to-analog converters, which convert digital readings to analog voltage; signal conditioners, which take care of input and output adjustments before they are read; and communication chips which makes communication speeds of up to 500 kilobits per second possible.
Although having a ECU in your car is great for the environment, this makes the car at risk to damage and inefficiency in the long run. One of the most important signals that your ECU is not working up to par is a decrease in mileage. There are different factors that can cause an ECU to perform below standard, such as temperature and humidity and the engine's condition which plays a huge part in how combustion takes place. Poor combustion results in a number of things, such as poor engine response and power output, an increase in fuel combustion and, of course, that funny sound the car produces when started. To ensure that ECU's are performing up to par, it is important to have them tuned-up every six months.
Ensuring that the car's ECU is in a good condition not only benefits the driver in terms of performance are minimizes cost repairs but it make the earth have a cleaner air to breathe. Lower fuel emissions released to the air can make a huge difference in making it a better place for us. that's why the ECU are important to be working properly.
