New-Style Turbocharger and Its Control System
Turbocharger of turbo-supercharged engine adds air input by compressing air. Usually, the exhaust gas produced by engine and the turbine is driven by the exhaust gas momentum. Then the turbine drives the coaxial impeller, and the impeller presses the air which comes from the pipe of air filter into the air cylinder. When the engines rotate speed is faster, the speed of exhaust air and turbines rotate speed are faster, too. So the impeller presses much air into the air cylinder. And the pressure and density of air in air cylinder are increasing at last; this will consume too much fuel eventually. So, the engines output power can be controlled by the quantity of fuel and the rotate speed of engine. Because a time difference existed in the process of turbo charging, and the out pressure which produced by the turbocharger always comes slowly. Usually, a good turbocharger needs two seconds to add or reduce the engines output power at least We have improved a kind of new-style turbocharger and its control system in accordance with the defect And the system has been passed some tests. Comparing with the conventional turbocharger system, tbe improved system has such advantages as low cost, high efficiency, and so on.
