摘要： PROBLEM TO BE SOLVED: To provide a control system of an internal combustion engine by which vibration caused in stopping the engine is suppressed, variations in the crank angle occurring at the time of an engine-shutdown can also be suppressed to conduct a favorable shutdown and start-up of the internal combustion engine.
SOLUTION: During the period from establishment of shutdown conditions of the internal combustion engine to the instant of an actual shutdown of the engine, when the engine speed is higher than a specified speed, the inlet air-flow in the cylinder of the engine is reduced (S102). During the above period, when the engine speed is lower than the specified speed, the inlet air-flow in the cylinder is increased (S106).

摘要： PROBLEM TO BE SOLVED: To provide sufficient combustion torque when a cylinder is ignited in an expansion stroke even if a stop position of an engine is uneven. SOLUTION: In this hybrid automobile, when engine restart conditions are satisfied and a piston of a fourth cylinder being the cylinder in the expansion stroke stops between a position of ATDC 90° and a position of exhaust valve opening, this cylinder is ignited to rotate the engine forward. At this time, since the cylinder in the expansion stroke has sufficient amount of air because volume of a combustion chamber 37 is comparatively large, large combustion torque is obtained. On the other hand, when the fourth cylinder stops in front of the position of ATDC 90°, a third cylinder being a cylinder in a compression stroke is ignited to rotate the engine reversely, the combustion chamber of the fourth cylinder is compressed, and then this cylinder is ignited to rotate the engine forward. At this time, volume of the combustion chamber of the fourth cylinder when stopping is comparatively small and it is difficult to obtain large combustion torque if held as it is, but it is ignited after it is compressed once, thereby obtaining large combustion torque.

摘要翻译：要解决的问题：即使在发动机的停止位置不均匀的情况下，当在膨胀行程中点燃气缸时提供足够的燃烧转矩。解决方案：在这种混合动力汽车中，当满足发动机重启条件时，膨胀冲程中的缸体的第四缸的活塞在ATDC 90°的位置和排气门开度的位置之间停止时，该气缸被点燃以使发动机向前旋转。此时，由于燃烧室37的体积比较大，膨胀冲程中的气缸具有足够的空气量，所以获得了大的燃烧转矩。另一方面，当第四气缸在ATDC 90°的位置前方停止时，点燃压缩行程中的气缸的第三气缸反向旋转发动机，第四气缸的燃烧室被压缩，然后该气缸被点燃以使发动机向前旋转。此时，停止时第四气缸的燃烧室的体积相对较小，如果保持原样，则难以获得大的燃烧转矩，但是在被压缩一次之后被点燃，从而获得大的燃烧转矩。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To improve probability of ignition after the engine restarts of air-fuel mixture put into a cylinder stopping in a compression stroke when an engine stops. SOLUTION: In this hybrid automobile, the engine is stopped when engine stop conditions are satisfied, but air-fuel mixture is put in the cylinder stopping in the compression stroke when the engine stops. When engine restart conditions after that are satisfied, cranking is performed by driving a motor, and the cylinder in the compression stroke is ignited when the cylinder in the compression stroke reaches ignition timing (S210 to S230). When air-fuel mixture in the cylinder in the compression stroke causes misfire, ignition is repeated until air-fuel mixture in the cylinder is ignited during a period when a piston of the cylinder reaches an ignition lag limit angle. Multiple ignition is repeated when air-fuel mixture in the cylinder is not ignited even if the piston in the cylinder exceeds the ignition retard limit angle (S240 to S280).
