  2. Four-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_engine

    Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.

    A Honda Super Cub engine. The most popular motorcycle in history, with over 100 million produced. A motorcycle engine is an engine that powers a motorcycle.Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.

  4. List of motorcycles by type of engine - Wikipedia

    List of motorcycles by type of engine is a list of motorcycles by the type of motorcycle engine used by the vehicle, such as by the number of cylinders or configuration. A transverse engine is an engine mounted in a vehicle so that the engine's crankshaft axis is perpendicular to the direction of travel.

  5. Stroke (engine) - Wikipedia

    en.wikipedia.org/wiki/Stroke_(engine)

    The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine.It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.

    Motorcycles commonly have from one to four cylinders, with a few high-performance models having six; although, some 'novelties' exist with 8, 10, or 12. Snowmobiles Usually have one to four cylinders and can be both 2-stroke or 4-stroke, normally in the in-line configuration; however, there are again some novelties that exist with V-4 engines

  7. Two- and four-stroke engines - Wikipedia

    en.wikipedia.org/wiki/Two-_and_four-stroke_engines

    The M4+2 engine has a four-stroke piston and a two-stroke piston. The shaft of the four-stroke piston rotates twice as fast as the shaft of the two-stroke piston, and the two-stroke part always runs at half speed. This ensures that both parts work optimally regarding fuel consumption at all times.

    The Honda CB400F is a motorcycle produced by Honda from 1975 to 1977. It first appeared at the 1974 Cologne motorcycle show, Intermot , and was dropped from the Honda range in 1978. [ 3 ] [ 4 ] It had an air-cooled , transverse -mounted 408 cc (24.9 cu in) inline four -cylinder engine with two valves per cylinder operated by a single chain ...

    The temperature range of an air-cooled two-stroke is even more extreme and component life even shorter than in an air-cooled four-stroke. As applied to motorcycles, two-stroke engines have some advantages over equivalent four-stroke engines: they are lighter, mechanically much simpler, and produce more power when operating at the high rpm power ...
