摘要:
The invention relates to an engine control unit 50 to ensure operational performance and safety performance of a vehicle 200 by carrying out switchover of combustion according to an operating condition of a vehicle (automobile) 200. A vehicle peripheral condition such as vehicular gap, etc., a traveling geographical state, a condition that ensures vehicle stability, etc. are acquired, and switchover of combustion, for example, switchover between compression ignition combustion and spark ignition combustion is effected correspondingly.

A control device for an internal combustion engine 1, which comprise a turbocharger 2, of which turbo flow rate is made variable, and an intake valve 11 provided with a variable valve mechanism and in which mirror cycle is performed, the control device comprising: device, which calculates an intake air quantity per unit time and an intake air quantity per cycle on the basis of torque required to the internal combustion engine 1; device, which controls the turbocharger 2 so that with the intake air quantity per unit time, supercharging pressure is further increased in that range, in which a ratio of supercharging pressure and exhaust pressure is equal to or less than a predetermined value; and device, which controls the variable valve mechanism on the basis of the supercharging pressure and the intake air quantity per cycle.
摘要:
The present invention provides a spark advance controller capable of controlling spark advance in an internal combustion engine (10) with high accuracy without requiring a larger number of data maps and performing laborious optimization tests using an actual engine. In the spark advance controller, map data for controlling the spark advance is computed by a numerical simulator (51) simulating an internal combustion engine (10), and the map data for spark advance control is approximated with a regression model. The spark advance is computed by using the regression model depending on the detected operating conditions.

A control device (28) for an internal combustion engine (1) which has a variable valve train capable of variably controlling opening/closing time or lift amount of at least one of an intake valve and an exhaust valve, and a turbo charger comprises: an internal EGR scavenging ratio arithmetic operation unit to, in a charging status, when intake pressure becomes higher in comparison with exhaust pressure, perform arithmetic operation to obtain an internal EGR scavenging ratio as an internal EGR ratio scavenged from a cylinder to the exhaust pipe and reduced in the overlap duration in which both the intake valve and the exhaust valve are opened; and a unit to control the overlap duration so as to control the internal EGR scavenging ratio to a predetermined ratio.
