Gasoline Engine EFI (Electronic Fuel Injection) Fuel System
The EFI system uses various sensors to detect the engine condition and vehicle running condition. And the engine ECU calculates at the optimum fuel injection volume, and causes the injectors to inject Read more Gasoline Engine EFI (Electronic Fuel Injection) Fuel System
Gasoline Engine Electronic Control System
The engine control system consists of three groups including sensors (and sensor output signals), engine ECU, and actuators. This chapter explains the sensors (signals), power circuitry and ground circuitry, Read more Gasoline Engine Electronic Control System
