Cummins Series Diesel Engine Turbochargers

Cummins Series Diesel Engine Turbochargers 

Turbocharger is one of the important parts of engine. Its function is to increase engine power. After the damage, the intake is insufficient, the combustion chamber pressure is low, the diesel combustion is incomplete, resulting in the engine crankshaft speed decline, the output force is weak. The rotating force of the crankshaft is transmitted to the flywheel, which is connected with the elastic plate of the torque converter and the cover wheel, which is connected with the pump wheel and the splitter teeth. The split gear controls the driving shaft of the steering pump and the hydraulic pump and the variable speed pump, so the damage of the supercharger will affect the whole machine.

Its construction is very simple, but its design is very sophisticated. The exhaust gas from the engine enters the two holes in the green ring, pushing the yellow ring turbine blade to rotate, while driving the other end of the purple ring compressor blade to rotate at a high speed. They share a shaft, and the supercharger starts to work. The high-speed rotating compressor presses the air after the filter element into the intake pipe. When the intake valve is opened, the intake gas in the combustion chamber increases, and the diesel atomized by the injector burns more completely, thus improving the power of the engine. The blue circle is the oil intake hole, and the black circle is the oil return hole.

The main purpose of turbocharging is to increase engine intake, which increases engine power and torque, making the car stronger. With a turbocharger installed, the maximum power of an engine can be increased by 40% or more compared with an engine without a turbocharger. This means that the same engine can be supercharged to produce more power.

Advantages and functions

1. Improve engine emissions. Turbocharger engine reduces harmful components such as particulate matter and nitrogen oxide in engine exhaust gas by improving engine combustion efficiency. It is an indispensable configuration for diesel engines to meet the emission standards above Euro 2.

2. Provide the function of plateau compensation. In some areas of high altitude, where the air becomes thinner at higher altitudes, turbochargers can overcome the loss of engine power caused by the thinner air at altitude.

3, improve fuel economy, reduce fuel consumption. Since engines with turbochargers burn better, they can save 3% to 5% of fuel.

4, with high reliability and good matching characteristics, high transient response characteristics.

Turbocharging device is actually a kind of air compressor, which compresses air to increase the intake volume of the engine. Generally speaking, turbocharging uses the inertia impulse of the exhaust gas discharged by the engine to promote the turbine in the turbine room, and the turbine drives the coaxial impeller, which compresses and delivers the air from the air filter pipe, and then pressurizes it into the cylinder. When the engine speed increases, the exhaust gas discharge speed also increases with the turbine speed, and the impeller compresses more air into the cylinder. The increase of air pressure and density can make more fuel fully burned. The corresponding increase of fuel amount and adjust the engine speed can increase the output power of the engine.
