  2. Mower blade - Wikipedia

    en.wikipedia.org/wiki/Mower_blade

    The first known lawn mower had a cylinder cutting gear made of iron. [citation needed] It was used to mow sporting grounds and wide-ranging gardens.As manufacturers changed the design and structure of mowers, the cutting mechanism also developed and evolved into several varieties, including cylinder/reel blades, deck blades, mulching blades, and lifting blades.

    Blade mounting and drive system: The blade of a rotary mower is usually mounted directly to the crankshaft of its engine, but it can be propelled by a hydraulic motor or a belt pulley system. Mower blade : A blade that rotates in a horizontal plane (about a vertical axis).

  4. D-400 engine - Wikipedia

    en.wikipedia.org/wiki/D-400_engine

    The D-400 series engine or the Iron Horse engine was a light-duty two-stroke engine used for powering lawnmowers produced from the 1950s to the late 1970s. D-400 engines were single-cylinder engines designed and manufactured by the Outboard Marine Corporation (OMC; Johnson and Evinrude) for Lawn-Boy [2] and Masport. The D-400 engines displaced ...

    en.wikipedia.org/wiki/Small_engine

    The combustion cycle can be either two-stroke (which results in a lighter engine for a given power output) [3] [4] or four-stroke (which produce lower levels of exhaust gas emissions). [5] [6] The fuel is usually either petrol or diesel. [7] In 1973, a small Wankel (rotary) engine manufactured by NSU was used in a lawn mower. [8]

  6. Turbocharger - Wikipedia

    en.wikipedia.org/wiki/Turbocharger

    Schematic of a typical turbo petrol engine. The simplest type of turbocharger is the free floating turbocharger. [44] This system would be able to achieve maximum boost at maximum engine revs and full throttle, however additional components are needed to produce an engine that is driveable in a range of load and rpm conditions. [44]

  7. Engine configuration - Wikipedia

    en.wikipedia.org/wiki/Engine_configuration

    1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...

  8. Turbine blade - Wikipedia

    en.wikipedia.org/wiki/Turbine_blade

    The turbine blades have a golden colour in this engine cutaway. A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. [2] Each turbine disc has many blades. [3] As such they are used in gas turbine engines and steam turbines.

  9. Variable-geometry turbocharger - Wikipedia

    en.wikipedia.org/wiki/Variable-geometry_turbocharger

    If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the ...
