Info on Bosch VP 44 Diesel Pumps for Diesel Trucks
出典: くみこみックス
If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the best model, than please continue studying. In this report we explain some common failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Unfortunately these injection pumps have been know to have their fair share of troubles and might need to be replaced.
Bosch VP44 injection pumps execute four basic functions:
1. Distributing the high-pressure, metered fuel to each and every cylinder at the precise time
2. Metering the exact quantity of fuel for every injection cycle
3. Varying the timing relative to engine speed.
four. Creating the high fuel pressure required for injection
The Bosch VP44 is an electronic rotary distributor pump that can differ fuelling and injection timing, and also consists of fuelling, timing, and diagnostic information.
The number one particular lead to of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Regular fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Bear in mind undesirable lift pumps can run unnoticed till costly damage is done to the Bosch VP44 injection alkaline water ionizer pump.
The following are the prime two most typical mechanical failures:
1. Check Engine Code 216
This is the most typical mechanical failure and happens more than a period of time when weak lift pumps, with low fuel pressure rupture the diaphragm in the consumers front of the injection pump. The timing piston will then vibrate to a point where it wears the housing of the pump down until the fuel is in a position to bypass the piston. Dodge has recognized this dilemma for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, instead they replace it with a unit that is now mounted in the tank.
two. Rotor Seizure
One more mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most widespread cause for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can yet again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, never ever to start off yet again, till the Bosch discount water ionizers VP44 injection pump is replaced.
Preventing Bosch VP44 injection pump Failure
The greatest way to keep away from failures of the Bosch VP44 injection pump is to avert them from occurring. Getting a replacement lift pump, one that is of a much better high quality than what comes from the factory will assist. If that choice is as well costly, you can also set up a gauge to monitor your fuel pressure. With the gauge you will be capable to know when your lift pump is going out and can very easily fix the dilemma just before you shed the Bosch VP44 injection pump.
Preventing problems before they occur is the best way to take care of your truck.
