What is PT fuel system?


What is PT fuel system?

PT fuel system is made from the fuel tank, float tank, filter, governor, PT fuel pump, injector and low- pressure pipeline and return pipe. When working, PT fuel pump is responsible for oil regulator, PT injector completes the tasks that generate high pressure and timing injection.

What is Cummins PT fuel system?

5-28) is exclusive to Cummins diesel engines; PT stands for “Pressure – Time”. It uses injectors that meter and injects the fuel with this metering based on a pressure-time principle. A gear-driven positive displacement low-pressure fuel pump naturally supplies fuel pressure.

What are the three factors that determine the amount of fuel flow in a PT fuel system?

The identifying letters, “PT” are an abbreviation for “pressure-time”. The operation of the Cummins PT Fuel System is based on the principle that the volume of liquid flow is proportionate to the fluid pressure, the time allowed to flow and the passage size through which the liquid flows.

What are the 6 fuel system delivery components?

The car fuel system is comprised of several different components to make this entire process happen smoothly. There is a fuel pump, fuel tank, fuel lines, fuel filter, fuel injectors, and carburetor.

What is fuel injection pump?

An Injection Pump is the device that pumps fuel into the cylinders of a diesel engine. Its timing is such that the fuel is injected only very slightly before top dead centre of that cylinder’s compression stroke. It is also common for the pump belt on gasoline engines to be driven directly from the camshaft.

What type of fuel system is used on the 2010 Cummins ISX engine?

The 1998-2010 ISX engines exclusively used the HPI-TP fuel system. — This generation of engines is rated between 385 to 600 BHP with peak torque values slightly exceeding 2,000 lb-ft. of torque.

How long should a fuel system hold pressure?

For the specification we must consult service-data, but the system should hold some pressure for about five-minutes.

What are the fuel system components?

The fuel system is made up of the fuel tank, pump, filter, and injectors or carburetor, and is responsible for delivering fuel to the engine as needed. Each component must perform flawlessly to achieve expected vehicle performance and reliability.
