Rotary Fuel Pumps Timing to engine steps

SMALL | MEDIUM | LARGE Previous Next Fuel Injection Pump (Distributor Type) The fuel injection pumps, Bosch® VE, Lucas CAV DPA, Stanadyne DB4, Lucas CAV DPS, and Delphi DP210, are rotary distributor pumps. These pumps perform the four basic functions of: 1. Producing the high fuel pressure required for injection 2. Metering the exact amount of fuel for each injection cycle 3. Distributing the high-pressure, metered fuel to each cylinder at the precise time 4. Varying the timing relative to engine speed. SMALL | MEDIUM | LARGE Previous Next Distributor-Type Pump Governor Balance between the governor flyweights and control lever position controls the metering of the amount of fuel to be injected. The fuel injection pump governor performance and setting can affect engine power. Special equipment and qualified personnel are required to verify governor performance. If the seals are broken on the external Bosch® VE adjustment screw, the fuel rate can, perhaps, be out of adjustment The Lucas CAV DPA/DPS fuel injection pump uses a coded spring connection to change the governor setting. Incorrect connection of the governor spring can affect performance. Adjustments and rating changes are described in the Master Repair Manual, Injector Pumps and Injectors, Manual Shutdown Levers Both fuel injection pumps are equipped with mechanical shutdown levers. These levers are spring-loaded in the run position. Not all applications will use these manual shutdown controls and there will be no cable or rod connected to the lever. NOTE: Partial actuation of the mechanical shutdown levers will affect fuel flow and engine power. SMALL | MEDIUM | LARGE Previous Next Advance Timing Mechanism Regulated pressure produced by a vane supply pump in both fuel injection pumps is used to advance the timing as the engine speed increases. A return spring is used to retard the timing as the engine speed is reduced. If a spring breaks, the timing will go to the advance position, resulting in torque loss, fuel knock, and possible engine overheating. Retarded (late) timing will result in torque loss, high fuel consumption, and white to black smoke. SMALL | MEDIUM | LARGE Previous Next The Lucas CAV DPA/DPS advance timing mechanism uses a check ball in the circuit which, if omitted during assembly, will result in no timing advance. If the fuel injection pump has been replaced or the mechanism has been removed to fix a leak, the problem can be that the check ball is missing
