How to Adjust the Fuel Supply Size of a Diesel Engine Oil Pump?
1 Answers
By rotating the plunger through the fork or rack, the effective fuel supply stroke of the plunger can be changed, thereby adjusting the fuel supply size. For mechanical pumps, the rack travel inside the fuel injection pump can be adjusted to increase it, thereby enhancing the fuel supply and making the vehicle more powerful. It is recommended to seek professional assistance for adjustments, as improper adjustments may lead to unnecessary issues. For electronically injected vehicles, external adjustments are not possible, and the ECU can be reprogrammed instead.
