IPC: F02B37/18
Filed: 1994-11-04
Abstract: PURPOSE: To avoid rapid reduction of supercharging pressure on the way of acceleration operation of a vehicle, and change supercharging pressure into a constant fully open supercharging pressure by controlling supercharging pressure in such a way that high side fully open supercharging pressure is gradually reduced When restrict control of supercharging pressure by high side fully open supercharging pressure is passed a prescribed time so as to change supercharging pressure into low side constant fully open supercharging pressure. CONSTITUTION: When an internal combustion engine 2 is started, it is judged by output of a throttle sensor 134 whether condition of acceleration is constant acceleration or rapid acceleration. At the time of constant acceleration, supercharging pressure by a supercharger 52 is restricted to constant supercharging pressure. On the other hand, at the time of rapid acceleration, a constant duty value is retrieved by characteristics of constant accelerating pressure which is found out by engine rotating speed, and also a correction duty value for rapid acceleration is retrieved, and then both values are summed up so as to obtain the summation duty value of the high side fully open supercharging pressure higher than constant supercharging pressure.  When restrict control of supercharging pressure by the high side fully open supercharging pressure is passed a prescribed time, the high side fully open supercharging pressure is subtracted per a set value and per a set time from the high side fully open supercharging pressure.
