Hello, I'm Jack, a diesel engine fan and a blogger. I write about how to fix and improve diesel engines, from cars to trucks to generators. I also review the newest models and innovations in the diesel market. If you are interested in learning more about diesel engines, check out my blog and leave your feedback.
The intake air temperature sensor detects the temperature of the intake air after it has passed the turbocharger. The sensor portion that detects the temperature…
• The accelerator position sensor converts the accelerator opening into an electric signal and outputs it to the engine ECU. There are two types of…
Crankshaft Position Sensor (Engine Speed Sensor) • The crankshaft position sensor is installed near the crankshaft timing gear or the flywheel. The sensor unit is…
(1) General Description • An EDU is provided to enable high-speed actuation of the injectors. The EDU has a high-voltage generation device (DC/DC converter) and…
The engine ECU constantly ascertains the status of the engine through signals from the sensors, calculates fuel injection quantities etc. appropriate to the conditions, actuates…
(1) Hollow Screw with Damper • The hollow screw with damper enhances injection quantity accuracy, by reducing the back-pressure pulsations (pressure fluctuations) of the leak…
In order to improve injector responsiveness, the actuation voltage has been changed to high voltage, speeding up both solenoid magnetization and the response of the…
The injector controls injection through the fuel pressure in the control chamber. The TWV executes leak control of the fuel in the control chamber to…
