Bosch VP 44 diesel pumps
Don’t give up on your diesel truck just yet. The performance issues may be contributed to the injection pump, specifically the Bosch VP44 injection pump in a Dodge Cummins diesel engine. What are Bosch VP 44 diesel pumps? The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also contains fuelling, timing, and diagnostic data.Bosch VP44 injection pumps perform four basic functions:
i) Metering the exact amount of fuel for each injection cycle ii) Producing the high fuel pressure required for injectioniii) Distributing the high-pressure, metered fuel to each cylinder at the precise time iv) Varying the timing relative to engine speed
It is a well known issue that the injection pumps installed in all the Cummins diesel engines manufactured by Dodge between ‘98 and ‘02 have had their fare share of problems with the Bosch VP44 injection pump.
