The evaporative emission control system is an environmentally friendly piece of auto technology. Its job is to contain fuel vapors in your vehicle and prevent them from escaping into the atmosphere and polluting it. Fuel vapor is a natural occurrence whenever you pump gasoline into your vehicle. Instead of polluting the outdoors, the evaporative emission … Read more
An engine misfire is a quite common occurrence. It is basically a situation where the timing of the ignition is off in the internal combustion chamber. In other words, as the air and fuel mix together in the chamber, the mixture is not ignited at the right tie. This could be due to a problem … Read more
The exhaust camshaft is responsible for controlling the valves which contain and release carbon emissions. The engine control unit is the computer which controls the timing and position of the exhaust camshaft. However, sometimes there will be situations where the timing of the camshaft is advanced or held back more than what the engine control … Read more
Air and fuel are the heart of the internal combustion process. The proper amount of air and fuel must enter the internal combustion chamber if the ignition is going to be successful. Otherwise, you might have a situation where your engine either consumes too much fuel or under performs. The engine control unit normally regulates … Read more
The internal combustion engine of a vehicle generates a vast amount of heat. The two liquids responsible for cooling the engine off are the oil and coolant. The latter is ultimately more important for this task. But if the coolant is going to do its job successfully, it needs to stay at a certain temperature … Read more
Modern vehicles are designed with an evaporative emissions system, also known as an EVAP system. When you pump fuel into your gas tank, there are vapors which emit from the fuel. If these fuel vapors were to escape your gas tank and reach the outside air, it would have a negative affect on the environment. … Read more
When the internal combustion process takes place, it creates a lot of toxic and dangerous pollutants. Vehicles have something in them called a catalytic converter which breaks down these exhaust emissions so that air pollution can be prevented or reduced. This component relies on a catalyst to break down these harmful pollutants. Some of which … Read more
An internal combustion engine can only function at the top of its game when the air to fuel ratio is just right. When air and fuel get mixed together, there must be roughly 15 parts of air for every 1 part of fuel. The engine control unit is responsible for making sure the engine is … Read more
The engine control unit of your vehicle is constantly monitoring your engine’s speed, particularly its idle speed. This refers to the number of revolutions per minute of the engine as your vehicle is not in motion. Your engine is idle whenever your vehicle stops at stop signs, stop lights, or parked with the engine running. … Read more
The power control module depends on the intake air temperature sensor to detect the temperature of the air that is going into the engine. This is air that comes from the outside environment. Once the sensor detects the temperature of the air, it sends back that information to the power control module. Based on this … Read more
