Data on Bosch VP 44 Diesel Pumps for Diesel Trucks
出典: くみこみックス
If you are searching for a new injection pump for your Dodge Cummins diesel engine, but are not confident which is the greatest model, than please continue studying. In this report we explain some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably these injection pumps have been know to have their fair share of issues and may need to be replaced.
Bosch VP44 injection pumps execute four fundamental functions:
1. Distributing the high-pressure, metered fuel to each cylinder at the precise time
2. Metering the precise quantity of fuel for each injection cycle
three. Varying the tyent turbo timing relative to engine speed.
4. Creating 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 contains fuelling, timing, and diagnostic data.
The quantity a single cause 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 below 5psi an injection pump failure is probable. Don't forget negative lift pumps can run unnoticed until pricey harm is carried out to the Bosch VP44 injection pump.
The following are the best two most widespread mechanical failures:
1. Verify Engine Code 216
This is the most typical mechanical failure water ionizer and happens 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 any longer, instead they copyright replace it with a unit that is now mounted in the tank.
two. Rotor Seizure
Yet another mechanical failure with the Bosch VP44 injection pump takes place when the rotor seizes in the distributor section of the pump. The most common result in for the seizure is a lack of lubrication. Since the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can once again be blamed for this failure. The seizure will then break the Drive Plate and the truck will cease running, by no means to begin yet again, until the Bosch VP44 injection pump is replaced.
Stopping Bosch VP44 injection pump Failure
The very best way to avoid failures of the Bosch VP44 injection pump is to avoid them from taking place. Acquiring a replacement lift pump, one that is of a much better top quality than what comes from the factory will support. If that alternative is also pricey, 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 effortlessly repair the problem just before you shed the Bosch VP44 injection pump.
Stopping difficulties ahead of they happen is the best way to take care of your truck.
