    Engines Translations

        1) The engine is the power plant that produces the energy needed to propel the vehicleand operate other systems. It converts the heat energy of a fuel (gasoline, diesel,alcohol,etc) into movement. The burning and expansion of the gases in the combustion chamberproduces pressure. The engine piston, connecting rod and crankshaft convert this pressureinto motion for moving the car and operating other systems.


        2) Four separate piston strokes are needed to produce one cycle, which are intakestroke,compression stroke, power stroke and exhaust stroke.


        3) Valvetrain opening/closing and duration, as well as the geometry of the valvetrain,controls the amount of air and fuel entering the combustion chamber at any given point intime.
