Automatic feeding mixer is a special vehicle more common in construction sites. Generally, the road conditions on construction sites are not good. Because the transportation medium of mixer is concrete and its weight is relatively large, it is more likely to choose engines with high horsepower and sufficient power. When buying vehicles, we often hear that intercooled supercharged engines and turbocharged engines.
Intercooling supercharging is when the turbocharger compresses the fresh air, cools it through the middle cooler, and then flows to the cylinder combustion chamber through the air inlet pipe and inlet valve. The intercooling technology can reduce the supercharging temperature below 50 ℃, which helps to reduce exhaust emissions and improve fuel economy.
Intercooling supercharging is actually an air compressor, which increases the air intake through compressed air. It uses the inertial impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, which presses the air sent by the air filter to increase the pressure into the cylinder.
When the engine speed increases, the exhaust gas discharge speed increases synchronously with the turbine speed, and the impeller compresses more air into the cylinder. The pressure and density of the air become larger, which can burn more fuel. By increasing the fuel and adjusting the engine speed, the output power of the engine can be increased.
