Diesel Engine Fuel Injection Pump 6CT for Cummins Generator Set Engine

In the complex and delicate operation system of diesel engine, diesel fuel pump plays an indispensable key role and dominates the core link of fuel delivery and power generation.

The work of diesel fuel pump begins with pumping action. Energized or mechanically driven at the beginning of the pump plunger, vanes or gears and other core components of the rapid operation of the pump cavity to form a local negative pressure. This suction is like an invisible hand, through the pipeline directly to the depths of the diesel fuel tank, strong pulling diesel fuel to the pump body rushed to ensure that the fuel supply is flawless.
After the fuel arrives, the pressurization program is staged. Pump body with a special structure, like a series of exquisite pressurized chamber, the inhalation of fuel step by step, the volume of sharp compression, pressure geometrically climbed. Take the common in-line plunger fuel pump as an example, the plunger in the camshaft driven by high-frequency reciprocating motion, each time the return stroke suction, the stroke is full pressure on the oil, oil pressure instantly up to dozens or even hundreds of atmospheres, enough to break through the nozzle of the tiny spray holes of the constraints.

Pressure-ready, precise fuel injection timed to open. Fuel pump and engine crankshaft, camshaft and other parts of the linkage, according to the rhythm of the piston movement, in the millimeters of the instant command injection nozzle injection. Under the high-pressure and high-temperature environment in the cylinder, the atomized diesel fuel is evenly dispersed and mingles with the air at high speed, and once ignited by the spark plug (diesel compression-ignition engine relies on high-temperature and high-pressure spontaneous combustion), it instantly releases a huge amount of energy, pushing the piston to do work furiously, driving the crankshaft to fly around, and efficiently converting the chemical energy into mechanical energy to make the vehicle run fast and make the machinery roar more than just a few times.

From the leisurely low-frequency operation at idle to the crazy high-load rhythm of full-load hill climbing, the diesel fuel pump is always fine-tuning the working conditions. With the help of built-in pressure regulator valve, governor perception of changes in working conditions, automatic regulation of fuel flow, pressure, to ensure that the engine power on call, the speed is as stable as Mount Tai, regardless of summer and winter wind and rain, has always been a loyal defender of the diesel power surging output, supporting the efficient operation of the beam of transportation, industrial production and other fields.
