    Mercury Marine, Mercury Racing, Tohatsu, Yamaha Marine, Nissan and Evinrude each developed computer-controlled direct-injected two-stroke engines. Each brand boasts a different method of DI. Fuel economy on both direct-injected and four-stroke outboards measures from a 10 percent to 80 percent improvement compared with conventional two-strokes.

    The cylinder head from the Toyota 4A-GE engine was developed by Yamaha and built at Toyota's Shimayama plant alongside the 4A and 2A engines. [ 28 ] In 1984, executives of the Yamaha Motor Corporation signed a contract with the Ford Motor Company to develop, produce, and supply compact 60° 3.0 Liter DOHC V6 engines for transverse application ...

  5. 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.

  6. Total-loss oiling system - Wikipedia

    en.wikipedia.org/wiki/Total-loss_oiling_system

    These engines were designed to have a total-loss lubrication system, with the motor oil held in a separate tank from the fuel in the vehicle, and not pre-mixed with it as with two-cycle engines, but mixed within the engine instead while running. Castor oil was often used because it lubricates well at the high temperatures found in air-cooled ...

    en.wikipedia.org/wiki/Two-stroke_power_valve_system

    A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...

  9. Engine balance - Wikipedia

    en.wikipedia.org/wiki/Engine_balance

    Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
