Overview of the Cummins PT Fuel System
The Cummins PT fuel system is a complex component of older diesel engines, including the 855 and L10 models. This system is responsible for pressurizing fuel and supplying it to the injectors, which then deliver the fuel to the engine’s cylinders. The PT pump plays a crucial role in this process, as it pressurizes the fuel pumped up from the float tank and supplies the pressurized fuel to the injectors. The amount of fuel being injected into each cylinder is controlled by changing the pressure of fuel delivered from the PT pump. The Cummins PT fuel system is designed to provide a precise amount of fuel to the engine, allowing for efficient operation and optimal performance. The system consists of various components, including the fuel pump, pressure regulator, throttle, governor, injectors, supply lines, shut-down valve, inlet connections, and drain lines. Understanding the overview of the Cummins PT fuel system is essential for proper maintenance and repair of the engine. The Cummins PT fuel system is a critical component of the engine, and its proper functioning is essential for the engine’s performance and longevity. The system requires regular maintenance and servicing to ensure optimal performance and prevent damage to the engine.
Components of the Cummins PT Fuel System
The Cummins PT fuel system consists of fuel pump, pressure regulator, throttle, governor, injectors, supply lines, shut-down valve, and drain lines, all working together to provide fuel to the engine, with specific functions and requirements.
Fuel Pump and Pressure Regulator
The fuel pump and pressure regulator are crucial components of the Cummins PT fuel system, working together to provide the correct amount of fuel to the engine. The fuel pump serves to pressurize the fuel pumped up from the float tank, supplying the pressurized fuel to the injectors. The pressure regulator plays a key role in controlling the pressure of the fuel delivered from the pump, ensuring that the correct amount of fuel is injected into each cylinder. The PT pump is designed to provide a consistent flow of fuel, regardless of engine speed or load, and the pressure regulator helps to maintain this consistency. The fuel pump and pressure regulator must be properly maintained and adjusted to ensure optimal engine performance, and any issues with these components can lead to decreased engine efficiency and potentially cause damage to the engine. Proper maintenance and adjustment of the fuel pump and pressure regulator are essential to extending the life of the engine and ensuring reliable operation. The Cummins PT fuel pump manual provides detailed information on the maintenance and adjustment of these components.
