摘要： PROBLEM TO BE SOLVED: To provide a controller for an internal combustion engine having a variable valve train capable of excellently preventing any fogging of an ignition plug and reducing the cylinder wet amount while maintaining fuel atomization effect using the inspiratory flow rate when performing the retarded opening control of an intake valve.
SOLUTION: The controller has an intake variable valve system 34 capable of changing the opening timing and the lift speed of an intake valve 30. During the cold start of an internal combustion engine 10, the intake valve retarded opening control for retarding the opening timing of the intake valve 30 from the intake top dead center is executed for promoting the fuel atomization. While performing the intake valve retarded opening control, the intake valve 30 is controlled so that the lift amount in the section from the opening timing of the intake valve 30 to the predetermined crank angle is higher in comparison with the lift curve longitudinally symmetric with the maximum lift position as the reference under the condition of the same operating angle.

摘要： PROBLEM TO BE SOLVED: To generate and add a reformed gas only when a fuel economy can be surely improved in an internal combustion engine utilizing the reformed gas. SOLUTION: Conditions for reforming are acquired (step S100), and a reforming efficiency under the conditions is predicted (step S102). A fuel economy enhancing rate when the engine is operated by adding a reformed gas to a hydrocarbon fuel under the present operating conditions is calculated (step S104). Based on the reforming efficiency and the fuel economy enhancing rate, a reforming is performed by a fuel reforming device under the present operating conditions, and an overall fuel economy enhancing rate when the engine is operated by adding the reformed fuel provided to the hydrocarbon fuel is calculated (step S106). The overall fuel economy enhancing rate is compared with a reference value (step S108). When the overall fuel economy enhancing rate exceeds the reference value, the reformed gas is generated and added (step S110). When it is equal to or less than the reference value, the generation and adding of the reformed gas are stopped (step S112). COPYRIGHT: (C)2008,JPO&INPIT
