Solved in 2 steps
- Explain steps involved in disconnecting a fuel line on a vehicle with multiport fuel injaction and gasoline direct injection ?When the throttle plates are closed in a port injection system, where does the air needed for idle speeds come from?Explain the steps involved in disconnecting a fuel line on a vehicle with: Multiport fuel injection (50 - 60 words) Gasoline Direct Iniection (30 - 40 words)
- List and explain the function of three (3) types of exhaust systems that can be fitted on diesel engines. (20 - 30 words each)2- Explain the differences and similarities between the engine temperature sensitivity and the incoming air temperature, and how do they affect the balance of the injected fuel volume determined by the electronic control unit?While discussing electronic fuel injection principles: Technician A says that the PCM always adjusts the air-fuel ratio in response to the O2S signals. Technician B says that cold air is dense, which is why the PCM enriches the mixture when the engine is cold. Who is correct?
