CONTROL DEVICE FOR ENGINE EQUIPPED WITH TURBO-SUPERCHARGER

Номер: US20170067394A1
Принадлежит: MAZDA MOTOR CORPORATION

Disclosed is a controller for a turbocharged engine. The engine includes a supercharger configured to supercharge intake air using an exhaust gas from the engine, and including movable flaps arranged so that a boost pressure generated in an intake passage is adjustable. If a rotational speed of a turbine and compressor that constitute the supercharger has reached a first threshold lower than an endurance limit, an amount of fuel injected to the engine is reduced to a predetermined amount. If the rotational speed has reached a second threshold lower than the first threshold, the amount of fuel injected is reduced in accordance with an excess of the rotational speed over the second threshold. 1. A controller for a turbocharged engine , the engine comprisinga supercharger configured to supercharge intake air using an exhaust gas from the engine, and including movable flaps arranged so that a boost pressure generated in an intake passage is adjustable, whereinif a rotational speed of a turbine and compressor that constitute the supercharger has reached a first threshold lower than an endurance limit, an amount of fuel injected to the engine is reduced to a predetermined amount,if the rotational speed has reached a second threshold lower than the first threshold, the amount of fuel injected is reduced in accordance with an excess of the rotational speed over the second threshold, andif the rotational speed has exceeded the first threshold, the shorter the amount of time it takes for the rotational speed to reach the first threshold from the second threshold, the higher a rate of decrease from the required injection amount of the fuel is set to be.2.
