Abstract
An engine-equipped vehicle capable of preventing gear noise and gear wear when the engine is started is provided. A multicylinder engine, a gear transmission that shifts power from the multicylinder engine by a shift operation, a centrifugal clutch arranged in a power transmission path from the multicylinder engine to the gear transmission, and an electronic control device that controls an operation of the multicylinder engine are included and the engine is configured to be started with a partial cylinder operation start where under control of the electronic control device, only some cylinders are operated and an operation of other cylinders is stopped.
Claims21
An engine-equipped vehicle comprising:
- a two-cylinder engine;
- a gear transmission that shifts power from the two-cylinder engine by a shift operation;
- a centrifugal clutch arranged in a power transmission path from the two-cylinder engine to the gear transmission;
- and an electronic control device that controls an operation of the two-cylinder engine, wherein
- the engine-equipped vehicle is configured so that the engine is started with a partial cylinder operation start where under control of the electronic control device, only a first cylinder is operated and an operation of a second cylinder is stopped, and
- the centrifugal clutch is arranged at an end of a crankshaft on a first cylinder side, and a ring gear is arranged at an end of the crankshaft on a second cylinder side, the ring gear becoming engaged with a starter when the engine is started, so that with the partial cylinder operation start, a rotation torque of the first cylinder and the rotation torque of the ring gear are applied to opposite sides of the second cylinder.
