Turbocharger Boost Compensator
1. Description When the intake air volume (boost pressure) is increased by the turbocharger, the boost compensator increases the maximum fuel injection volume in accordance with the increased intake air Read more Turbocharger Boost Compensator
Diesel Engine High-Altitude Compensator (HAC)
1. Description
At high altitudes, the air density decreases with the decrease in the atmospheric pressure. For this reason, if the fuel is injected under the same conditions as at low altitudes, the air-fuel Read more Diesel Engine High-Altitude Compensator (HAC)
Diesel Engine Automatic Timer (Injection Timing Control)
As in the case of gasoline engine ignition timing, diesel engine injection timing must be advanced (or retarded) in accordance with the engine speed in order to obtain optimum performance. Advancing or Read more Diesel Engine Automatic Timer (Injection Timing Control)
Diesel Engine Fuel Cut-off Solenoid
The fuel cut-off solenoid valve opens and closes the fuel passage leading to the suction port. (The valve remains open while the ignition switch is on.)
1. Fuel cut-off solenoid on
The battery voltage Read more Diesel Engine Fuel Cut-off Solenoid
Diesel Engine Injection Pump System
The injection pump pumps the fuel to each injection nozzle.
The injection pump functions to control the fuel injection volume and timing.
1. Fuel suction
The feed pump draws the fuel from the Read more Diesel Engine Injection Pump System
Other Diesel Engine Equipment Intake Shutter
1. Description
Some diesel engines use an intake shutter. The intake shutter has following functions.
(1) Stops vibration immediately after engine is turned off. In diesel engines, air continues Read more Other Diesel Engine Equipment Intake Shutter
Deisel Engine Vehicles Glow System
1. Glow indicator light description
The glow plug indicator light is mounted inside the combination meter. When the light goes off, it informs the driver the engine is ready to be started.

Diesel EnginePreheating System
1. Necessity of preheating system
At a cold engine starting, the compression heat escapes from the compression chamber even if there is adequate compression. In some cases, the injected fuel does not Read more Diesel EnginePreheating System
Fuel System of Diesel Engine 2 of 2
2. Necessity of adjusting nozzle opening pressure
For the injection nozzle, the nozzle opening timing varies according to the nozzle needle opening pressure. If the injection nozzle does not open or Read more Fuel System of Diesel Engine 2 of 2
