摘要： During start-up of an engine, an engine unit is controlled to perform a reverse rotation start-up operation. In the reverse rotation start-up operation, a fuel-air mixture is introduced into a combustion chamber while a crankshaft is rotated in a reverse direction, and the fuel-air mixture is ignited such that the crankshaft is driven in a forward direction. In the reverse rotation start-up operation, an ignition threshold value is set based on a first parameter corresponding to friction of the engine, and the fuel-air mixture in the combustion chamber is ignited when a second parameter corresponding to pressure in the combustion chamber reaches the set ignition threshold value.

摘要： During start-up of an engine, a crankshaft is rotated in reverse such that a crank angle reaches a start-up ignition range across a start-up intake range. At least part of the start-up intake range is in a normal compression range, and the start-up ignition range is in a normal intake range. A fuel-air mixture is introduced into a combustion chamber when the crank angle is in the start-up intake range, and the fuel-air mixture in the combustion chamber is compressed when the crank angle is in the normal intake range. After that, when the crank angle is in the start-up ignition range, the fuel-air mixture in the combustion chamber is ignited and then combusted.

摘要： During start-up of an engine, a reverse rotation start-up operation is performed in which a crankshaft is rotated in a forward direction after being rotated in a reverse direction. An engine unit is controlled such that the reverse rotation start-up operation is performed again, in a case in which a rotation state detected by a rotation state detector does not satisfy a predetermined start-up condition when the crankshaft is rotated in the forward direction in the reverse rotation start-up operation and before a piston reaches a first compression top dead center. A fuel injection device injects fuel such that a fuel-air mixture is introduced into a combustion chamber from an intake passage through an intake port in at least the first reverse rotation operation. An ignition device ignites the fuel-air mixture in the combustion chamber.

摘要： A camshaft rotates in forward and reverse directions in conjunction with a rotation of a crankshaft in the forward and reverse directions. An intake cam and a sub-intake cam are provided at the camshaft. The intake cam acts on an intake valve within a range of a crank angle corresponding to an intake process by integrally rotating with the camshaft. The sub-intake cam is rotatable within a constant angular range with respect to the camshaft, thereby being movable between a normal position and a start-up position in a circumferential direction of the camshaft. During the rotation of the crankshaft in the reverse direction, the sub-intake moves to the start-up position by rotating with a delay relative to the intake cam.

摘要： An EUC controls an engine and an integrated starter generator such that an engine start-up operation including at least a reverse rotation start-up operation is performed. In the reverse rotation start-up operation, a fuel-air mixture is introduced into a first cylinder while a crankshaft is rotated in a reverse direction, and the crankshaft is driven in a forward direction by combustion of the fuel-air mixture in the first cylinder. A decompression mechanism, in the engine start-up operation, reduces pressure in the first cylinder or another cylinder such that an increase in rotational resistance of the crankshaft caused by an increase in pressure in the first cylinder or the other cylinder is inhibited.

摘要： A forward rotation positioning operation of rotating a crankshaft in a forward direction is performed before start-up of an engine, and a reverse rotation start-up operation of rotating the crankshaft in a reverse direction is performed during the start-up of the engine. In the forward rotation positioning operation, a rotation driver drives the crankshaft such that a crank angle reaches a predetermined reverse starting range. In the reverse rotation start-up operation, the rotation driver drives the crankshaft such that the crank angle exceeds a predetermined start-up intake range from the reverse rotation starting range and reaches a predetermined start-up ignition range, a fuel injection device injects fuel such that a fuel-air mixture is introduced into a combustion chamber from an intake passage through an intake port, when the crank angle is in the start-up intake range, and an ignition device ignites when the crank angle is in the start-up ignition range. Ignition performed by the ignition device is prevented during the forward rotation positioning operation.
