Embodiment Construction

[0021] Such as figure 1 As shown, the vehicle according to the preferred embodiment comprises a motorcycle 1 . However, the vehicle according to the preferred embodiment of the present invention is not limited to the motorcycle 1 . Vehicles according to preferred embodiments of the present invention may be other straddle vehicles or other non-straddle vehicles. In addition, "motorcycle" also includes small motorcycles and the like in addition to so-called motorized bicycles.

[0022] The motorcycle 1 includes a vehicle body 2, front wheels 3 and rear wheels 4 mounted to the vehicle body 2, and an engine 5 that drives the rear wheels 4 through a drive chain (not shown). In the preferred embodiment, the engine 5 preferably comprises a single-cylinder four-stroke internal combustion engine.

[0023] Such as figure 2 As shown, the engine 5 includes an engine body 10 , an intake passage 11 and an exhaust passage 12 . Engine block 10 includes housing crankshaft 42 (see image...

Abstract

A single cylinder engine includes an engine body having a cylinder and a combustion chamber, an intake opening that faces the combustion chamber, and an intake passage in communication with the combustion chamber through the intake opening, a piston provided in the cylinder, an ignition plug arranged in a position within about 5% of a bore diameter of the cylinder from an axis of the cylinder, a throttle valve provided in the intake passage, a sensor that detects an opening degree of the throttle valve, and an ECU that causes the ignition plug to lag in ignition timing during two or three cycles when the throttle valve is increased in opening degree from an idling state.

Description

technical field [0001] The present invention relates to a single cylinder engine and a vehicle provided with the same. Background technique [0002] Conventionally, it is known that an engine mounted on a vehicle is prone to knocking at the time of acceleration. Ignition timing control devices that suppress knocking at the time of acceleration have been proposed. For example, the specification of US Patent No. 4,448,163 discloses a control device that retards the ignition timing by a predetermined number of cycles when the accelerator pedal is depressed while the vehicle is stopped or driven at a steady speed. [0003] The control device is applied to a vehicle, such as an automobile, that is accelerated by depressing an accelerator pedal. The control device is considered to be applied to a multi-cylinder engine. [0004] On the other hand, single-cylinder engines with only a single cylinder are known in addition to multi-cylinder engines. Single-cylinder engines differ ...
