How KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 Works：

  KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 consists of turbo chamber and supercharger. The turbo chamber air inlet is connected to the exhaust manifold, and the exhaust port is connected to the exhaust pipe ; The intake port of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. The turbine and the impeller are installed in the turbine chamber and the supercharger respectively, and the two are rigidly connected coaxially.

  The exhaust gas turbine is connected to the intake impeller via a shaft. They all have vanes, and the turbine and impeller are each housed in a helical chamber that controls and directs the exhaust and intake air. The shaft connecting the turbine and the impeller is mounted in the bearing. The exhaust gas flow is directed by the nozzles towards the turbine blades. When the engine load is large enough, there is enough exhaust gas flow to make the turbine and turbine shaft rotate at high speed, and this rotating motion creates a vortex. Because the impeller is on the other end of the shaft, it must also rotate with the turbine shaft. The pump wheel is installed in the air intake system. When the pump wheel rotates, the air is sucked into the center of the turbine, and the blades of the pump wheel drive the air to rotate, so that the air is thrown out under the action of centrifugal force, and the air leaves the pump wheel shell and enters the inlet under the action of pressure. Air Manifold. The increase in pressure in the intake manifold increases the amount of air-fuel mixture entering the cylinders, thereby increasing the power of the engine.

Advantages of KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470：

1. KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 can improve engine liter power. When the engine displacement is unchanged, the density of the intake air can be increased to allow the engine to inject more fuel, thereby increasing the power of the engine. The power and torque of the engine after adding a supercharger should be increased by 20% to 30%. On the contrary, under the requirement of the same power output, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced.

2. KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 can improve engine emissions. Turbocharger engines reduce the discharge of harmful components such as particulate matter and nitrogen oxides in the engine exhaust by improving the combustion efficiency of the engine. It is an indispensable configuration for diesel engines to meet emission standards above Euro II.

3. KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 can provide the function of plateau compensation. In some high-altitude areas, the higher the altitude, the thinner the air, and the engine with a turbocharger can overcome the power drop of the engine caused by the thin air on the plateau.

4. KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 can improve fuel economy and reduce fuel consumption. Due to the better combustion performance of the engine with a turbocharger, it can save 3%-5% of fuel.

5. KTR90 6506-21-5020 Turbo For Komatsu PC400-8 PC450-8 Excavator WA450 WA470 has high reliability, good matching characteristics and high transient response characteristics.
