摘要： A start control apparatus for a port injection internal combustion engine (1) starts the engine (I) by supplying fuel to an intake stroke cylinder in which a piston (5) is stopped in an intake stroke, when a predetermined start condition is fulfilled. The start control apparatus includes a throttle valve (20). The position of the throttle valve (20) is switchable between a closing position (P1) in which the throttle valve (20) decreases a flow passage sectional area of an intake port (3a), and an opening position (P2) in which the throttle valve (20) fully opens the intake port (3a). The, start control apparatus determines whether a piston (5) in the intake stroke cylinder is stopped in a predetermined crank angle range, when the predetermined start condition is fulfilled. When it is determined that the piston (5) in the intake stroke cylinder is stopped in the predetermined crank angle range, the start control apparatus switches the position of the throttle valve (20) to the closing position (P1), and then, starts the engine (1).

摘要： A stop-start control apparatus for a port injection engine (1) including cylinders (2) stops the engine (1) by stopping fuel injection from each injector (13), when a predetermined stop condition is fulfilled. An estimated position of a piston (5) in each cylinder (2) after the engine (1) is stopped is determined during a stop process period from when the predetermined stop condition is fulfilled until when the engine (1) is stopped, and a compression stroke cylinder in which the piston (5) is to be stopped in a compression stroke is identified. An amount of fuel to be injected from the injector (13) for the compression stroke cylinder during the stop process period is set based on the estimated position of the piston (5) in the compression stroke cylinder. The injector (13) injects the fuel in the set fuel amount so that the fuel is contained in the compression stroke cylinder when the engine is stopped.

摘要： Provided is a control apparatus and a control method of an internal combustion engine which can intend to suppress a deterioration of an emission and suppress a reduction of a startability. According to the method, a target ignition timing at a time of starting an internal combustion engine is acquired (step ST101); an ignition timing is controlled to a spark advance side and an air fuel ratio of the internal combustion engine is controlled to a lean side (step ST103) if a start of a cranking is judged (step ST102); the ignition timing is controlled to a spark retard side (step ST106) if an end of a first cycle after the cranking is judged based on the acquired engine speed (steps ST104 and ST105); and a spark advance correction of the ignition timing to a spark advance direction in correspondence to an exhaust temperature is executed until the ignition timing comes to the target ignition timing (steps ST108, ST109, and ST110).
摘要翻译：提供了能够抑制发射劣化并抑制起动性降低的内燃机的控制装置和控制方法。根据该方法，获取起动内燃机时的目标点火正时（步骤ST101）。如果判断起动开始，则将点火正时控制到火花提前侧，并且将内燃机的空燃比控制为稀薄侧（步骤ST103）（步骤ST102）。如果基于所获取的发动机转速来判定起动后的第一循环的结束，则点火正时被控制到火花发动机侧（步骤ST106）（步骤ST104和ST105）。执行与排气温度对应的向火花提前方向的点火正时的火花提前校正，直到点火正时达到目标点火正时（步骤ST108，ST109，ST110）。
