Abstract
PURPOSE: To improve starting-up property of an engine and also respending property to loads for feeding fuel from idle port and slow port to the side near the engine through a blower compressor in a domain where a throttle valve closes or a little opens.
CONSTITUTION: During operating of an engine, an exhaust gas enters an exhaust turbine 3 through an exhaust passage 5, which is rotated to run a blower compressor 2. In this case, the exhaust gas is little at the time of idling for which a throttle valve 18 closes and in a low-load and low-rotation area for which the throttle valve 18 opens a little, and a supercharger 2 runs too slowly to carry out supercharging. Under the condition a negative pressure works on an idle port 19 and a slow port 20, therefore the fuel is fed directly to a supercharging passage 6 form the ports 19, 20 taking a circuitous way from the blower compressor. Next, a turbosupercharged condition is obatined through opening the throttle valve 18 further, check valves 26, 27 at the ports 19, 20 close, and thus the fuel is fed through main nozzle 9 of a carburetor 7.
