In the four cylinder engine, the ECU calculates the appropriate injection timing for each cylinder and the air fuel mixture is made available at each suction stroke.

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.
