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 certain which is the best model, than please continue reading. In this post we explain some typical failures with injection pumps. The Cummins diesel engine manufactured by Dodge 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 issues and may possibly require to be replaced.
Bosch kyk water ionizer VP44 injection pumps carry out four basic functions:
1. Distributing the high-pressure, metered fuel to each cylinder at the precise time
two. Metering the precise quantity of fuel for each injection cycle
three. Varying the timing relative to engine speed.
four. Making the high fuel pressure needed 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 number one cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is normally due to a malfunctioning lift pump. Normal fuel pressure is around 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Don't forget poor lift pumps can run unnoticed until expensive damage is accomplished to the Bosch VP44 injection pump.
The following are the top two most typical mechanical failures:
1. ionized water machines 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 till the fuel is capable to bypass the piston. Dodge has recognized this difficulty for some time, and they no longer even sell the lift pump that goes on the side of the block any longer, as an alternative they replace it with a unit that is now mounted in the tank.
2. Rotor Seizure
Yet 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 once again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, in no way to begin yet again, until the Bosch VP44 injection pump is replaced.
Stopping Bosch VP44 injection pump Failure
The greatest way to avoid failures of the Bosch VP44 injection pump is to prevent them from taking place. Acquiring a replacement lift pump, 1 that is of a better quality than what comes from the factory will help. If that solution is as well pricey, you can also install 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 fix the dilemma prior to you lose the Bosch VP44 injection tyent uce-9000t chat pump.
Stopping difficulties just before they occur is the best way to take care of your truck.
