The ECU detects the operating conditions of the engine based on the signals from various sensors. Based on this information, the ECU electrically controls the fuel injection volume and injection Read more What is EFI-diesel?
Generally, the valve timing is fixed, but the VVT-i system uses the hydraulic pressure to shift the intake camshaft rotation and vary the valve timing. This makes it possible to increase output, improve Read more VT-i (Variable Valve Timing-intelligent)
The manifold pressure sensor is used with D-type EFI for sensing the intake manifold pressure. This is one of the most important sensors in D-type EFI. By means of an IC built into this sensor, the manifold Read more Manifold Pressure Sensor (Vacuum Sensor)
In this system, the temperature of the hot-wire (Rh) is continuously maintained at a constant temperature higher than the temperature of the intake air by using the thermistor (Ra). Consequently, since Read more Diesel Engine Air Flow Meter
