The Shutdown Solenoid Valve is not Closed Tightly
The shutdown solenoid valve is not closed tightly, which is one of the key reasons for the diesel engine’s trouble installation. The power to the solenoid of the solenoid valve is cut off when the key is switched off, the solenoid valve should be closed, and the fuel passage going to the cylinder head is sealed; if the shutdown solenoid valve is not tightly closed, there will be fuel leakage. The diesel engine does not stall because a small amount of gasoline continues to flow to the cylinder head oil channels.
The shutdown solenoid valve is not tightly closed for a variety of reasons, including processing issues and fuel cleanliness. Impurities in the gasoline will invade the solenoid valve, pad the valve plate, or make its movement stuck, resulting in a loose closing; impurities may also directly infiltrate during the maintenance process without paying attention to the cleanliness of the oil circuit.
When the solenoid valve is not tightly closed and it is difficult to turn off the flame, the accelerator can be increased to strike the valve plate, closing the oil circuit and turning the engine off quickly. Cleaning the solenoid valve should be done after the failure occurs, but the most essential thing is to increase the cleanliness of the fuel, otherwise, the failure will occur again. If you happen to have a problem with your solenoid valve 1832232c95, we have many high-quality solenoid valves in our store for you to choose from.
Deformation and Damage of the Fuel Injection Pump Rack
The fuel injection pump rack has become jammed. The rack of the fuel injection pump is stuck, the plunger of the fuel injection pump cannot be rotated, the fuel supply cannot be stopped, and the diesel engine cannot be turned off due to improper assembly or bending and deformation of the rack.
The fuel injection pump should be disassembled at this time for examination and maintenance. If the fuel injection pump’s rack is bent and deformed, it can be straightened by tapping it on the platform without damaging the surface; if the rack and gear have badly meshed, a small file can be used for local correction; be repaired.
The fuel injection pump rack’s lugs come off. The projecting handle on the diesel engine’s fuel injection pump rack is welded. It will fall off due to poor welding or excessive force, preventing the throttle handle from moving the fuel injection pump rack and the fuel injection pump from changing the fuel volume, preventing diesel engines from being shut off.
The fuel injection pump rack should be replaced or the lug re-welded at this time. The repaired or replaced fuel injection pump rack, on the other hand, must be able to mesh properly with the adjustment gear and move smoothly.
Improper Adjustment of the Throttle Control Mechanism
The governor’s outer lever control arm should collide with the high-speed limit screw when the vehicle accelerator handle is in the maximum fuel supply position, restricting the maximum fuel supply and maximum speed. The governor’s outer lever control arm collides with the low-speed limit screw when the throttle control handle is dragged to the flameout position, stopping the diesel engine.
The stroke of the throttle control handle is too small, and the throttle control handle is not pulled enough to stop the fuel injection pump, if the positions of the high-speed limit screw and the low-speed limit screw are not adjusted properly, or the length of the control arm of the governor’s outer lever is not adjusted properly. The control arm of the governor’s outer lever collides with the low-speed limit screw in this position, the fuel injection pump is still providing continuous fuel, and the diesel engine cannot be shut off.
There are so many ways to solve the problem of engine stalls. The article contains the reasons and solutions for this problem, and I hope it will help you.
