IC Engine Practice Test: Electronic Injection Systems — Flashcards

Electronic Injection Systems topics include: Gasoline injection, electronic injection system, electronic control systems, injection timing and group gasoline injection system.

Here are some basics of an electronic injection system:
Fuel pump: Located inside the fuel tank, the fuel pump works when the engine is starting and running.
Injectors: The injection system places the injectors in the right position to deliver fuel directly to the cylinders. This improves fuel efficiency and torque without increasing the engine size.
Fuel filter: An integral part of the injection system, the fuel filter prevents clogged fuel injectors from producing a stream that doesn't completely ignite.
Fuel rail: In the common rail system, the fuel is distributed to the injectors from an accumulator, called the rail. The rail is fed by a high pressure fuel pump.
Sensors: Essential parts of electronic control systems, sensors are used to keep track of various vehicle parameters, including fuel consumption, pollution, and airbag deployment.
Throttle body: A critical component in the electronic fuel injection system, the throttle body regulates the airflow to the engines.
