Types of SPV (Spill Control Valve) for Diesel Engine Control System
Injection Volume Outline of SPV
There are two types of SPV (Spill Control Valve) that control the injection volume.
Conventional type SPV
(used in axial plunger type pump)
Direct-acting type SPV
(used Read more Types of SPV (Spill Control Valve) for Diesel Engine Control System
Fuel System of Conventional EFI-diesel
In the conventional EFI-diesel, control of injection timing and volume is performed electronically. The device that generates the fuel pressure is the same pump used in an ordinary diesel engine.

What is EFI-diesel?
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?
Fail-safe and Back-up Function 2 of 2
Back-up Function
The back-up function switches over to fixed signal control by the back-up IC to permit driving in cases when a malfunction occurs in the microcomputer inside the engine ECU. The back-up Read more Fail-safe and Back-up Function 2 of 2
