What are the accessories for turbochargers
The turbocharger is used to increase power to increase power, mainly used to increase air density. The power is exhaust gas from the internal combustion engine. The exhaust gas flows from the turbine inlet housing through the nozzle ring to increase the flow rate and low temperature channels, and then blows to the turbine blades to drive the turbine to rotate. At this time, the coaxial compressor takes in air, and the air enters the cooling device through the volute and diffuser to be cooled down, and then reaches the cylinder of the internal combustion engine. The whole interior has the following parts: rotor (turbine blade, impeller, main shaft, compressor impeller, guide wheel), vortex end accessories (nozzle ring, vortex end bearing seat, radial bearing or floating bearing, vortex end gas seal) ring ), press fitting (bearing, radial bearing or floating bearing, thrust bearing, main or auxiliary thrust bearing, thrust bearing and thrust plate, diffuser, side air seal ring) accessories.
How to boost the turbocharger?
The turbocharger is mainly composed of a turbine and a compressor, which are connected by a drive shaft. The intake port of the turbine is connected to the exhaust manifold of the engine, and the exhaust gas is connected to the exhaust pipe. The air inlet of the compressor is connected to the air inlet pipe, and the air outlet is connected to the air inlet manifold. The exhaust gas from the engine hits the turbine, causing the coaxial compressor to rotate at high speed, forcing compressed air into the cylinder.
Turbocharging mainly uses the energy of the engine exhaust to drive the compressor to increase the intake air. In the whole process, the engine hardly consumes power and has good acceleration continuity. However, at low speeds, the turbine cannot intervene in time and has a certain lag.
How a turbocharger works
The turbocharger increases the amount of intake air by compressing air, and uses the exhaust gas from the engine to push the turbine into the turbine chamber. The turbine in turn drives the coaxial impeller, which pressurizes the air from the air filter tube and pressurizes it into the cylinder. When the engine speed increases, the exhaust speed and turbine speed also increase simultaneously. The impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel, which increases the amount of fuel and adjusts the engine speed accordingly. You can increase the output power of the engine.
