摘要： The present teaching aims to provide a control device for a rotating element rotated by a four-stroke engine, having a high degree of freedom in the choice of an apparatus to which the control device is applicable. The control device includes: a rotation speed acquisition unit configured to obtain a rotation speed of the rotating element rotated by the four-stroke engine; and an undulation detection unit configured to, based on a rotation speed obtained by the rotation speed acquisition unit, detect a periodic undulation contained in a rotation fluctuation of the four-stroke engine, the periodic undulation having an angular period longer than a crank angle corresponding to four strokes.

摘要： An object of the present teaching is to provide an air-cooled engine that is able to improve cooling efficiency, and particularly cooling efficiency at a time of initial sliding of a piston part. The present teaching provides an air-cooled engine including a piston part and a cylinder body part with a sliding surface on which the piston part is slidable. The cylinder body part includes a heat dissipation portion provided on an outer surface of the cylinder body part, and is made of an Al-containing metal. At least an inner peripheral portion of the cylinder body part, which includes the sliding surface, is made of an Al alloy with an Si content of 16% by mass or more. The sliding surface is configured such that a plurality of substantially parallel linear grooves are formed therein and Si primary crystal grains having an average crystal grain diameter of 8 µm or more and 50 pm or less are exposed thereon so as to be contactable with the piston part. An Al contact portion where an Al alloy base material has contact with the piston part, which is formed between the plurality of linear grooves, is exposed on the sliding surface at a location between two adjacent Si primary crystal grains. Al contained in the cylinder body part is physically continuous from the Al contact portion to the heat dissipation portion.

摘要： To provide a drive control device for a vehicle capable of driving an engine at a desired fuel consumption. The drive control device has a map which correlates each engine rotation speed with an evaluation value indicating a fuel consumption in driving the engine at that engine rotation speed. The drive control device calculates a targeted evaluation value Etg between a first evaluation value Elim1 indicating a fuel consumption in driving the engine in the fuel economy mode and a second evaluation value Elim2 indicating a fuel consumption in driving the engine in the acceleration responsive mode. Further, the drive control device calculates a target engine rotation speed Stg correlated to the targeted evaluation value Etg, with reference to the map.

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.

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.
