Turbocharger mechanism and working principle
Turbocharging is driven by the exhaust gases from the engine. The turbine consists of two parts, one is the fresh air booster end (compressed pump wheel), the other part is the exhaust gas drive end (exhaust gas turbine), there is one impeller at each end, and there is a leak between the two sides of the turbine on the same shaft. The pressure gate is located on the side of the exhaust turbine. When the compression turbine pressure is too high, the pressure pushes the trigger to open the valve of the exhaust turbine to lower the air pressure to prevent over pressurization.
The support of the turbine axle is a sleeve, and the bearing design inside the sleeve can be divided into a ball bearing and a floating bearing. The rotational power of the turbocharger impeller comes from the exhaust. The exhaust gas drives the turbine, and on the other side of the turbine, the blades compress the air. The turbocharger housing is made of nickel, chrome and silicon alloy and the shaft is made of chrome and molybdenum alloy. More importantly, the turbocharger works under high temperature and high speed conditions. To ensure its normal operation, the oil and coolant are introduced into the turbocharger to ensure effective lubrication and cooling, and improve working conditions.
