Information on Bosch VP 44 Diesel Pumps for Diesel Trucks
出典: くみこみックス
If you are looking for a new injection pump for your Dodge Cummins diesel engine, but are not sure which is the finest model, than please continue reading. In this write-up we explain some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Sadly these injection pumps have been know to have their fair share of concerns and may possibly want to be replaced.
Bosch VP44 injection pumps execute 4 basic functions:
1. Distributing the high-pressure, metered fuel to each cylinder at the precise time
two. Metering the exact quantity of fuel for every injection cycle
three. Varying the timing relative to engine speed.
4. Generating the high fuel pressure necessary 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 data.
The quantity one particular result in of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Typical fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Don't forget undesirable lift pumps can run unnoticed until expensive damage is done to the Bosch VP44 injection pump.
The following are the best two most frequent mechanical failures:
1. Examine Engine Code 216
This is the most common mechanical failure and occurs more than a period of time when weak lift pumps, with low fuel pressure rupture the diaphragm in the front of the injection pump. The timing piston will then vibrate to a point where it wears the housing of the pump down till the fuel is capable 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, as an alternative they replace it with a unit that is now mounted in the tank.
2. Rotor Seizure
Another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most typical lead to for the seizure is a lack of lubrication. Given 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 quit operating, by no means to begin once more, until the Bosch VP44 injection pump is replaced.
Preventing Bosch VP44 injection pump Failure
The finest way to stay away from failures of the Bosch VP44 injection pump is to prevent them from happening. Buying a replacement lift pump, a single that is of a greater good quality than what comes from the factory will assist. If that alternative is too pricey, you can also set up a gauge to monitor your fuel pressure. With the gauge reverse osmosis filter you will be in a position to know when your lift pump is going out and can easily repair the difficulty before you lose small blue arrow the Bosch VP44 injection click for ionizer oasis pump.
Stopping troubles before they take place is the greatest way to take care of your truck.
