摘要： PROBLEM TO BE SOLVED: To provide a start control device for an internal combustion engine which can quickly restart from idle stop with a simple structure. SOLUTION: When a condition for idle stop is met, the start control device stops the engine and outputs a fuel injection instruction to fuel injection valves of all engine cylinders to inject restarting fuel (S10-S14). When a condition for restart is met, the device activates the starter and starts cranking (S16-S18). Then, the device lights up spark plugs of a cylinder #1 and a cylinder #4, or, a cylinder #2 and a cylinder #3 by a first chipped dent of a sensing ring which came by a crank angle sensor, and starts the engine by combusting the restarting fuel which is injected and inhaled into combustion chambers when the engine is stopped (S20-S22, S30).

摘要： PROBLEM TO BE SOLVED: To provide a variable valve gear of an internal combustion engine which can promptly learn a control range of a variable control member without causing mechanical trouble.
SOLUTION: When the internal combustion engine is in an operating state (S02), a position at a predetermined proximate distance from a regulation member is set to a control target position with reference to a minimum value of a control range of a variable control member up to the present (S03). After an actuator is operated at a first speed or higher so as to force an operating position of a variable control member to be the position at a predetermined proximate distance (S04), the actuator is operated at a speed not higher than a second speed which is lower than the first speed until the variable control member is determined to reach the position of the regulation member (S05, S06). When the variable control member is determined to reach the position of the regulation member, an operating position detected by a variable operating position detection means is learned as the minimum value of a new control range of the variable control member (S07-S10).

摘要： PROBLEM TO BE SOLVED: To provide a controller of an engine improving combustion characteristics in a combustion chamber and suppressing an increase in the size of a storage section (memory) storing a map. SOLUTION: The controller of the engine includes: the storage section storing a setting map defining a parameter value affecting a combustion state in the combustion chamber of an engine, according to an alcohol concentration in a mixed fuel; a concentration detection means detecting the alcohol concentration in the mixed fuel; and a parameter value setting means appropriately referring to the setting map and setting a predetermined parameter value according to the alcohol concentration detected by the concentration detection means. In the storage section, a transport delay correction map is stored as one of the setting maps.
