You start the car, press the gas pedal, and you expect the engine to rev and the car to accelerate. If every system associated is working in optimal condition, this is that must happen. The parts involved are the fuel delivery system, ignition components, and exhaust system. However, even a slight problem in any of the systems mentioned above could lead to car hesitating and bucking when accelerated, deceleration, or when standing idle.
When the driver presses the gas pedal, the fuel pump of the car sends a fuel line through the fuel filter, that reaches the injectors traveling up the pipeline. In the “injectors” section, gasoline is “atomized” (turned into fin mist) where the spark plug ignites the gasoline, which after combustion, moves the pistons and finally turns the engine.
This combustion process creates fumes, also known as exhaust, that must be vented. This is then done through a very complicated combination of several components. Most of the fumes are sent through the exhaust manifold, the catalytic converter, and then finally leaving through the exhaust pipe. In all this complex process, some of the exhaust is recirculated and burned again in the injectors (using the EGR valve) and oxygen sensor monitor and exhaust process for the right level of contaminant.
