摘要:
A drive train of a motor vehicle, having a drive assembly which has at least one internal combustion engine (1), having a transmission (3) which is connected between the internal combustion engine (1) and an output (2), and having a starter clutch (4) which is connected between the internal combustion engine (1) and the transmission (3), having a bypass transmission (5) which can be connected in parallel with the starter clutch (4) and has at least one transmission stage (6) and an additional clutch (7), wherein in order to reduce the rotational speed of the internal combustion engine (1) in the overrun mode of the drive train the additional clutch (7) is closed and the starter clutch (4) is at least partially opened.

An engine (1) includes a crank case (2) which rotatably supports a crank shaft (6). Formed on the crank case (2) are first transverse walls (73) positioned below and in the vicinity of crank webs (6c, 6d) of the crank shaft (6) and curved along outer peripheral surfaces of the crank webs (6c, 6d). Formed on the crank case (2) are second transverse walls (74) positioned above and in the vicinity of gears (43 to 46) on a main shaft (41) to cover upper portions of the gears. Formed on the crank case (2) is an oil scattered space (98) extending to the second transverse walls (74) from the first transverse walls (73) in the vicinity of the outer peripheral surfaces of the crank webs (6c, 6d). Downwardly projecting projections 94 are formed on the second transverse walls (74). The crank shaft (6) rotates in a direction, in which the crank webs (6c, 6d) move toward a transmission (25) from the first transverse walls (73).
摘要:
The present invention provides an engine cover structure for an engine (1) whose cylinder head (7) is covered at three of front, rear, right and left sides thereof by a fuel tank (10), an air cleaner (20) and a muffler (9), respectively, comprising a cover (50) which covers the remaining one side and/or a top side of the cylinder head (7).
摘要:
An air intake apparatus for a four-cycle internal combustion engine comprises air intake passages passing into at least one combustion chamber and throttle valves disposed in said air intake passages. Fuel injection valves are provided in close proximity to the throttle valve in the air intake passage, and at least one damping valve being arranged upstream of the throttle valve to vary the cross section of said air intake passages according to the air intake conditions, and to dampen increased air intake flows resulting from the aperture of the foregoing throttle valve.
摘要:
An intake apparatus of an internal combustion engine for a vehicle comprises a duct for taking into a wind during a running of a vehicle, an air cleaner operatively connected to the duct, a fuel supply device for injecting a fuel into an intake air coming from the air cleaner, a movable valve arranged between an outlet port of the duct and an inlet port of the air cleaner, a negative-pressure motor for driving the movable valve, and an electronic control unit for controlling the movable valve. The electronic control unit is connected to an ignition means, and the electronic control unit controls the opening and closing of the movable valve in accordance with a rotational speed of an internal combustion engine, an opening degree of a throttle of the engine and a gear position of the engine as control parameters and carries out a delay angular control of an ignition timing in response to the opening and closing control of the movable valve.
摘要:
The present invention relates to a supercharged engine structure (15) for a motorcycle (2) comprising a connecting rod (25) substantially dividing an interior of a crankcase into first and second air chambers (B), wherein the first air chamber (A) is connected to an air introduction unit via an air cleaner (35) while the second air chamber (B) connects to a combustion chamber via an intercooler which cools the air output from said second air chamber (B) and an air intake passage connected to an outlet of said intercooler (36), wherein said second air chamber (B) serves as a compression chamber and said connecting rod (25,33) forming a compressor element by changing an effective internal volume of the crankcase. In order to reduce or inhibit the inflow of lubricating oil from the crankcase compression chamber to the combustion chamber, an outlet of said intercooler (36) being located at an upper portion of said intercooler (36).
摘要:
The present invention relates to an induction system for a multiple valve internal combustion engine, specifically a 5-valve motorcycle engine, comprising a plurality of intake valves (40b,40c,40d) for each cylinder served by an intake manifold (29) to which an intake passage (62) for each cylinder is connected via an outer connecting port (27h) leading to individual valve ports of the intake valves, and a fuel injection arrangement having at least one fuel injector (31) for charging the intake valve ports. Specifically, the fuel injector is disposed above the engine in an area between an air cleaner (20) and the air intake manifold/intake passage-arrangement.
