EspañolTurbocharging is driven by exhaust gas and is cheaper, while mechanical supercharging is driven by an engine and is more expensive. The specific differences between the two are as follows:
1. The principle of action is different: Supercharging is to provide high-pressure air at the intake end of the engine, so that the air actively enters the cylinder, so the supercharging can let the cylinder enter more mixed gas and improve the engine power.
(1). Turbocharging is the use of engine exhaust energy to pressurize the air. The turbocharger is installed on the exhaust manifold. The exhaust gas from the engine drives the turbine to rotate, and the turbine drives the coaxial compressor impeller to add air After being compressed, it is delivered to the intake port of the engine to achieve supercharging. The turbocharger needs to be driven by exhaust gas, and when the engine rotates at a low speed, the exhaust gas volume is not enough to drive the supercharger to achieve sufficient boost pressure, so the turbocharged engine must reach a certain speed before it has a boost effect. Moreover, there is a delay from stepping on the accelerator to the increase in exhaust gas volume, so turbocharged engines have turbo delays.
(2). The mechanical supercharging is driven by the engine, which is connected to the engine through a belt, and drives the internal screw air compressor to provide intake supercharging for the engine. Since the supercharger is directly connected to the engine, there is almost no delay in supercharging, and supercharging can be provided as soon as the engine is started, so the engine power output is very smooth, and some luxury cars use supercharging to achieve better driving quality.
2. The price is different:
(1) The turbocharger is cheaper, but the turbocharger has a high working temperature, which requires higher heat dissipation from the engine.
(2). The price of a supercharger is higher, and the higher the speed of the supercharger, the greater the moment of inertia, and the more power it consumes. Therefore, the supercharger consumes a lot of engine power in the high speed range because the supercharger consumes a lot of engine power. The maximum power will be limited. Summary: Supercharged is more like the icing on the cake, suitable for use in situations that require high driving quality. The turbocharger is more like a stimulant, with the lowest possible cost to get the power you want.
