AI Technical Summary

Technical Problem

Existing multi-cylinder diesel engines suffer from incomplete fuel combustion when operating at low loads, which easily leads to carbon buildup. They also have high maintenance costs, poor economic efficiency, and are difficult to operate in low-load areas for extended periods.

Method used

The system employs a hydraulic telescopic lever and a solenoid valve control system to enable single-row ignition starting of the diesel engine. It controls the diesel engine load through a stop-start system, reducing fuel consumption, improving low-load operating capability, and lowering the rate of carbon deposit formation.

Benefits of technology

By using a shutdown and exhaust system, fuel consumption is reduced, diesel engine economy is improved, maintenance cycles are extended, carbon deposit formation rate is reduced, and automated and intelligent control of high-power diesel engines is achieved.

Abstract

The application provides a multi-row cylinder diesel engine stop exhaust system and belongs to the technical field of diesel engine control. Specifically, a three-jaw rocker arm is rotatably sleeved on a rocker shaft, one jaw of the three-jaw rocker arm is connected with a speed regulator through a pull rod structure, a second jaw of the three-jaw rocker arm is hingedly connected with one end of a hydraulic telescopic A-row pull rod, the other end of the hydraulic telescopic A-row pull rod is connected with a plurality of oil injection pumps of an A-row through an A-row elastic reset control rod mechanism; a third jaw of the three-jaw rocker arm is hingedly connected with one end of a B-row pull rod, the other end of the B-row pull rod is connected with a plurality of oil injection pumps of a B-row through a B-row elastic reset control rod mechanism; the rocker shaft, the three-jaw rocker arm and the hydraulic telescopic A-row pull rod are internally provided with communicated oil holes, an electromagnetic valve is communicated with the oil holes through an oil path, and the electromagnetic valve is also communicated with diesel engine lubricating oil with a certain pressure in a lubricating oil system through an oil path. The application is based on a system for controlling and switching of a fluid hydraulic piston rod in two states of no pressure / pressure, and realizes single-row ignition starting of a diesel engine.
