摘要： A motorcycle (saddle type vehicle) includes a vehicle body frame, an engine, a bracket and an ignition coil. The engine is mounted to the vehicle body frame. The bracket is mounted to the vehicle body frame. The ignition coil is mounted to the bracket. The bracket includes a frame mounting part, an extension part, and an ignition coil mounting part. The frame mounting part is mounted to the vehicle body frame. The extension part extends away from the frame mounting part toward an outer side in a left-right direction. The ignition coil is mounted to the ignition coil mounting part such that the ignition coil is positioned in the outer side in the left-right direction of the vehicle body frame.

摘要： Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as “weave.” A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.

摘要： An electric generator for generating electric energy upon rotation of a crankshaft supported in a crankcase of an internal combustion engine has an outer rotor and an inner rotor. An electric generator cooling structure includes a first cooling oil passage and a second cooling oil passage that are branched from a lubricating oil passage of a lubricating system of the engine toward the electric generator. A first ejection port is defined in a downstream end of the first cooling oil passage for ejecting lubricating oil to an outer side surface of the outer rotor, and a second ejection port is defined in a downstream end of the second cooling oil passage for ejecting lubricating oil to the inner stator disposed in the outer rotor. The electric generator cooling structure can thus efficiently cool the electric generator in its entirety.

摘要： An engine is disclosed of the V-configuration having an integrated engine and transmission. The engine has a crankshaft which directly couples to drive the water pump, oil pump and transmission clutch. The water pump has a drive shaft coupled to the crankshaft that extends across the crankcase from a first to a second side. The water pump includes a housing where at least a portion is defined in the face of the crankshaft.

摘要： An engine for a two-wheeled vehicle includes at least one cylinder comprising a combustion chamber and a cylinder head positioned adjacent the combustion chamber. The engine further includes a crankcase coupled to the at least one cylinder which includes a crankshaft. Additionally, the engine includes a valve train operably coupled to the crankshaft which includes at least one intake valve fluidly coupled to the combustion chamber, at least one exhaust valve fluidly coupled to the combustion chamber, at least one pushrod operably coupled to at least one of the intake valve and the exhaust valve, at least one camshaft operably coupled to the at least one pushrod and the crankshaft, and a cam phaser assembly operably coupled to the at least one camshaft and positioned generally outside an envelope of the cylinder head.

摘要： In a water-cooled inner combustion engine (1), in particular for equipping scooters and motorcycles, the arrangement of the outer cooling tubes connected to a radiator is simplified by arranging a by-pass valve (27), arranged directly on the engine block (2) at a discharge opening (18) obtained therein, which, when the cooling water is lower than a reference temperature, prevents the water circulation in the radiator (18) and it addresses it through a by-pass line (26) by implementing a cooling circuit wholly included in the engine block (2).

摘要： A saddle-type vehicle can be driven by finer control by judging the driver's demand based on operation of the driver relative to the vehicle when the engine is started from the idle-stop state. A saddle-type vehicle can include bar handle mounted on its opposite tip ends a grasping grip grasped by the driver and a throttle grip for an accelerator operation; an engine controller for automatically stopping an engine and making the engine an idle-stop state: and a clutch. The saddle-type vehicle can include a judgment controller for judging a driver's demand based on operation conditions of the driver relative to the vehicle and a clutch controller for selecting a travel state and a stopped state.

摘要： An apparatus is provided including an insert for an engine. The insert includes an elongated body sized to be positioned in an opening defined in the engine. The elongated body extends along a longitudinal axis from an upper end to a lower end. A fin extends outwardly from the elongated body. A flange extends outwardly from at least one of the fin and the elongated body. A locking mechanism is coupled to the elongated body and is moveable along the longitudinal axis between a first position in which the locking mechanism is positioned in the elongated body and a second position in which the locking mechanism extends outwardly from the lower end of the elongated body.
