The engine idle speed, throttle speed can be increased rapidly, but it is not easy to continuous throttle speed increased, driving speed weakness, or use more stalls can not travel, this is caused by the low pressure oil supply shortage.
The reason
Blockage of diesel oil filter or oil water separator.
Low pressure oil passage.
Insufficient oil supply or plugging of oil inlet strainer.
The North-Benz V3 accessories tank cover inlet valve failure.
The above conditions can cause the fuel pressure in the low pressure oil chamber of the injection pump is insufficient, only to maintain the small amount of oil required to load. For large and medium load need more oil supply, they can not meet, resulting in weak driving.
The diagnosis and treatment methods
Check the fuel tank cap inlet valve failure, if failure will make the tank form a certain vacuum degree, diesel can not be sucked out. This phenomenon is mostly the tank cover is lost, with airtight sealed by plastic sheeting.
Check the North Run V3 fittings low-pressure oil pipe has concave concave, into the oil pipe joint filter at the plug.
If the fuel oil filter or oil water separator has not been replaced for a long time, it should be replaced in time.
Check the beiben V3 accessories pump is working properly, if the pump oil supply shortage, should be the timely replacement or repair.
