Diesel generator exhaust gas turbocharging system: this is our usual turbocharging device, the supercharger has no mechanical connection with the engine, in fact, it is an air compressor, which increases the intake volume by compressing air. It uses the inertia impulse of the exhaust gas discharged by the engine to promote the turbine in the turbine room, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase, the impeller compresses more air into the cylinder, the air pressure and density increase can burn more fuel, and the corresponding increase in the amount of fuel can increase the output power of the engine.
In general, the engine power and torque after the installation of exhaust gas turbochargers should be increased by 20%-30%. However, the exhaust gas turbocharger technology also has its place that must be noted, that is, the pump wheel and the turbine are connected by a shaft, that is, the rotor, the exhaust gas discharged by the diesel generator drives the pump wheel, the pump wheel drives the turbine to rotate, and the turbine turbocharges the intake system after rotation. The supercharger is installed on the exhaust side of the engine, so the working temperature of the supercharger is very high, and the rotor speed of the supercharger is very high when working, which can reach hundreds of thousands of revolutions per minute. Such a high speed and temperature make the common mechanical needle roller or ball bearings unable to work for the rotor, so the turbocharger generally uses full floating bearings, which are lubricated by oil. There is also coolant to cool the supercharger of the diesel generator.
