1. Introduction Numerous parts of an automotive makes up an engine but without having sensors andactuators engine does not work appropriately. However, operation of engine is totally relyingon sensors and actuators and control on emission would not possible without them. Thus,each component is significantly important in the engine machine and there are many sensorsand actuators in the engine. As a result, features of some sensors and actuators along with thenames, symbols, their single waveforms will be determined and also different types ofpressure charging systems with its pros-cons will also be demonstrated.
2. Types of sensors 2.1 Oxygen Sensor (O2 Sensor) Fuel mixture information is gathered from the oxygen sensor. Further, PCM/ECUuses the fuel mixture information for the purpose to rearrange the mixture of air/fuel.A poor sensor of oxygen will result in using of more fuel and more radiations willproduce. The cause behind the poor sensor of oxygen is due to its oldness and also due to anoil consuming engine. Symbol of an O2 sensor in a wiring diagram.
