  • Supercharging pressure control method for internal combustion engines
    Patent number: 5224853
    Abstract: A method of controlling supercharging pressure in an internal combustion engine is disclosed. The supercharging pressure is controlled based on a basic control amount determined in dependence on operating conditions of the engine. When the transmission is in a lower speed position, the basic control amount is corrected so that the supercharging pressure is lower than a value assumed when the transmission is in a higher speed position. When the engine is in a feedback control mode, the basic control amount is corrected in response to the difference between the actual supercharging pressure and a desired value of the same. The desired value of the supercharging pressure is set lower when the transmission is in the lower speed position than a value assumed when the transmission is in a higher speed position.

The desired value of the supercharging pressure is set lower when the transmission is in the lower speed position than a value assumed when the transmission is in a higher speed position. When the transmission is in the lower speed position, the rising speed of the supercharging pressure in a transient states is set lower than a value assumed when the transmission is in a higher speed position.
