摘要： PROBLEM TO BE SOLVED: To minimize reduction of engine output associated with knocking avoiding control and securely avoid the knocking. SOLUTION: An internal combustion engine equipped with a variable compression ratio mechanism capable of variable-controlling compression ratio is capable of reducing the compression ratio or lagging ignition time for the knocking avoiding control when a knock sensor detects knocking. In a relation of engine rotation speed Ne to loading Tp, the compression ratio reduction is carried out with priority on the lower speed side than a predetermined rotation speed NCR, and when the compression ratio reaches the limit, the ignition time is lagged. Lagging the ignition time is carried out with priority on the higher speed side than the NCR, and when the ignition time reaches the limit, the compression ratio is reduced. The output reduction is minimized as the influence of the compression ratio and the ignition time depends on operation conditions such as the rotation speed. The knocking can be securely avoided as for delay of changing the compression ratio in the high speed range. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To achieve compatibility between acceleration responsiveness and improvement of fuel consumption by making compression ratio control at the time of acceleration appropriate.
SOLUTION: The internal combustion engine is equipped with a compression ratio variable mechanism utilizing a dual-link type piston-crank mechanism, a turbo supercharger and an inter cooler. An intake air temperature sensor is provided at an outlet of the inter cooler to detect the inter cooler outlet temperature ICTemp. When an acceleration in which an accelerator pedal opening APO rapidly increased was detected, it determines correction amount of compression ratio, and corrects a target compression ratio based on the difference between the inter cooler temperature ICTemp and the intake air temperature in a steady state. Since the change of the intake air temperature has a time constant depending on a heat capacity of the inter cooler, the intake air temperature in an initial acceleration stage is lower than that in the steady state, and knocking hardly occurs, it is possible to increase a compression ratio ε. The acceleration response and fuel consumption are improved by correcting as shown in a dashed line.

摘要： PROBLEM TO BE SOLVED: To provide a switching procedure for the combustion states of an internal combustion engine when the internal combustion engine having two combustion systems not allowed to co-exist with each other in a same operating range is applied to a hybrid vehicle. SOLUTION: When the internal combustion engine 1 switchable between a compressive self-igniting combustion and a spark ignition combustion having different operating ranges is applied to the hybrid vehicle and the combustion state of the internal combustion engine 1 is switched, the supply of fuel to the internal combustion engine 1 is stopped by stopping a fuel injection device 12, and a first electric generator 2 is driven by a discharge from a battery 4 to switch the operating range of the internal combustion engine 1 before the supply of fuel is re-started. While the supply of fuel to the internal combustion engine 1 is stopped, a second electric generator is driven by the discharge from the battery 4 and the vehicle is run. Thus, the hybrid vehicle capable of realizing a low fuel cost/low emission while coping with a wide vehicle load can be provided by properly switching between two combustion states.
