Title:
DIESEL ENGINE, DIESEL ENGINE MANUFACTURING METHOD, AND DIESEL ENGINE INJECTION-AMOUNT CORRECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/026518
Kind Code:
A1
Abstract:
[Problem] To provide a diesel engine, a diesel engine manufacturing method, and a diesel engine injection-amount correction system that enable easy improvement of the accuracy of correcting fluctuations in a fuel injection amount. [Solution] A diesel engine 30 comprises: an injector 4 that uses a solenoid to directly drive a needle valve and inject fuel; and an injector control device 2 that controls driving of the injector 4. The injector control device 2 has: a charge voltage control circuit 22; a storage unit 25 that stores a correction value relating to the injection amount of fuel injected from the injector 4; and an injector control circuit 24 that controls the driving of the injector 4 on the basis of the voltage supplied from the charge voltage control circuit 22 and the correction value stored in the storage unit 25. The correction value is set according to a voltage applied to terminals of the injector control device 2, which is connected to a load connected to the injector control device 2 when current begins to flow through the load.
