Abstract: Methods and systems for reducing the temperature of the charge air provided to a turbocharged internal combustion engine. A supercharger is installed on the air intake path, upstream the turbocharger's compressor. A secondary charge air cooler is installed between the supercharger and the main compressor.

Abstract: In a vehicle condition in which an engine rotation speed is likely to exceed a maximum rotation speed, since supercharging by a supercharger is curbed, it is possible to curb an increase in an engine torque. Even when the engine rotation speed exceeds the maximum rotation speed, the engine rotation speed is made less likely to increase by control of decreasing the engine torque. In a vehicle condition in which the engine rotation speed is less likely to exceed the maximum rotation speed, since a supercharging pressure becomes relatively high, it becomes easier to secure power performance. Accordingly, it is possible to curb a decrease in power performance due to curbing of supercharging and to prevent an engine from falling into a high-rotation state in which the engine rotation speed exceeds the maximum rotation speed.

Abstract: Since a maximum rotation speed is set to a lower value when a supercharging pressure from a supercharger is high than when the supercharging pressure is low, an engine torque is decreased at a relatively low engine rotation speed and the engine rotation speed is less likely to fall into a high-rotation state. Since the maximum rotation speed is set to a relatively high value when the supercharging pressure is relatively low and the engine rotation speed is less likely to fall into a high-rotation state, the engine torque is not decreased at a relatively high engine rotation speed and power performance can be easily secured. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the engine torque and to prevent the engine rotation speed from falling into a high-rotation state.

Abstract: Turbocharged engine water vapor ingestion control techniques determine a dew point of a charge air cooler (CAC) in an induction system of the engine based on measured humidity and temperature of a mixture of (i) air drawn into the induction system and (ii) exhaust gas produced by the engine that is cooled and recirculated by a low pressure cooled exhaust gas recirculation (LPCEGR) system of the engine back into the induction system.
