What is P-pump diesel?
What is P-pump diesel?
This injection pump, often called a “P-pump,” is the Holley Four-barrel carburetor of the diesel world. The P7100 pump has been around forever, is practically bulletproof, and is very tunable for high performance. Cummins Injection Pump Overview.
What is the difference between 4BT and 4BTA?
Types Of 4BT’s The 4B models were non-turbo, the 4BT was turbocharged (T for turbo), the 4BTA was turbocharged (T) and after-cooled (A), and the 4BTAA was turbocharged with an air-to-air intercooler (AA).
What is the difference between P-pump and pump?
Called a distributor style pump, the Bosch VE is an axial-piston injection pump that differs from the P7100 is several ways, but one key distinguishing feature is its use of a single fuel metering plunger vs. the P-pump’s six (or four on a 4BT).
What years were Cummins P-pump?
1994-1998 12V Cummins (12 Valve) Features The first variation of the second gen cummins features the desirable “p-pump” fuel injection pump. New injectors, a larger intercooler, and a new turbocharger were also introduced. These additions help reduce emissions output compared to the previous generation.
What is a 4BTA Cummins?
Second generation engines, known as 4BTA engines, use 4 valves per cylinder, and produce higher performance numbers. The most common iterations of the 4BTA Cummins Diesel engine produce 170 horsepower and 420 lb-ft of torque. The 4BT Cummins Engine was way ahead of its time when it was released in the ’80s.
How much horsepower can a Cummins 4BT make?
In our experience, the 4BT’s stock rotating assembly—which was only subjected to 105 hp in factory form—can handle up to 400 horsepower and 800 lb-ft of torque without breaking a sweat.
How does P-pump work?
The function of a P-pump is relatively simple, although it may take a few readings to understand. The pump basically acts like a small engine, but instead of compressing air, the rotating plungers compress fuel to thousands of pounds per square inch needed for diesel injection.
What is a VE pump Cummins?
The VE injection pump is a mechanically controlled, axial-piston rotary pump. It uses a vane-type supply pump to generate an internal pump pressure that increases with engine speed. It has a single pumping plunger, called a distributor plunger.
What is AP pump?
The P-Pump, as Tyler puts it, is “basically a little engine in itself.” Driven by the engine’s cam gear, the P-Pump is an injection pump that gets fed fuel from the lift pump (which takes fuel from the tank). The injection pump’s six plungers—which ride on a camshaft in the pump housing—move up and down in barrels.
How do I identify my Bosch injection pump?
The Bosch part number will be located on the component either on a parts ID tag riveted to the housing, on a parts sticker or printed onto the plastic moulding of the component.
