Data 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 greatest model, than please continue reading. In this post 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. Sadly these injection pumps have been know to have their fair share of problems and might need to be replaced.

Bosch VP44 injection pumps carry out four simple functions:

1. Distributing the high-pressure, metered fuel to each cylinder at the precise time

two. wholesale chanson water ionizer Metering the precise quantity of fuel for each and every injection cycle

three. Varying the timing relative to engine speed.

four. Generating the high fuel pressure expected for injection

The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also contains fuelling, timing, and diagnostic data.

The number 1 trigger of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is generally due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Bear in mind negative lift pumps can run unnoticed until expensive harm is accomplished to the Bosch VP44 injection principles pump.

The following are the top two most common mechanical failures:

1. Check Engine Code 216

This is the most widespread 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 exactly where it wears the housing of the pump down until the fuel is able 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, rather 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 occurs when the rotor seizes in the distributor section of the pump. The most common lead to for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can again be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease running, by no means to start once more, until the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The best way to stay away from failures of the Bosch VP44 injection pump is to avert them from taking place. Getting a replacement lift pump, 1 that is of a far better top quality than what comes from the factory will help. If that solution is also pricey, you can jump button also set up a gauge to monitor your fuel pressure. With the gauge you will be able to know when your lift pump is going out and can simply fix the problem ahead of you shed the Bosch VP44 injection pump.

Stopping troubles prior to they happen is the finest way to take care of your truck.
