Analysis of the Principle and Usage Method of Denso Diesel Pumps in Japan
I. Core Working Principle: Precise control of high-pressure common rail technology
Denso diesel pumps in Japan take the high-pressure common rail system as the core and achieve precise control of fuel injection through the coordinated action of solenoid valves and hydraulic pistons. Its principle can be divided into the following stages:
Although Delphi and Caterpillar common rail injectors belong to different technical systems, both achieve precise fuel injection with high-pressure common rail technology at their core. Their working principles can be elaborated from four aspects: structural composition, fuel pressure control, injector working mechanism, and technical advantages.
How to deal with the phenomenon of the plunger of the diesel engine fuel injection pump getting stuck
Jamming of the diesel engine fuel injection pump plunger is a common fault. It may be caused by reasons such as the plunger being bent, impurities entering, the positioning screw being too long, the pump body base being uneven, or the new plunger pair being stored for too long. The following are the specific handling methods
The fuel injector is mainly composed of components such as solenoid valves, needle valves, valve bodies, spray holes, springs and armature, etc. Each component works in coordination to achieve precise fuel injection.
Maintenance and upkeep of fuel injectors
The maintenance and upkeep of fuel injectors should start from multiple aspects such as fuel management, regular cleaning, sealing performance inspection, and optimization of driving habits. The specific measures are as follows:
Select light diesel oil that meets the standards. The sedimentation time should exceed 48 hours to remove impurities. Avoid using fuel containing water or mechanical impurities.
Regularly clean or replace the diesel filter element. According to the working environment, promptly remove the sludge and moisture at the bottom of the diesel tank to prevent impurities from corroding the fuel injection pump plunger, fuel outlet valve pair and transmission components.
