#Power stroke - Fuel combusts and piston is pushed downwards. #Exhaust stroke - Exhaust is driven out. This is a large improvement on the existing image; it is higher resolution, has smoother animation and removes some of the unnecessary detail.

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.
#Exhaust stroke - Exhaust is driven out. Reason Suggested replacement, a much larger version is also available. A superior version of this animation is now available.

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 same principles apply to having two ...
Desaxe engines are usually automotive, but the term can also apply to steam engines. An animation of a Scuderi Split Cycle Engine. If the offset is in the direction of rotation, it has the effect of increasing the leverage applied to the crankshaft during the "power" stroke, and reducing thrust wasted against the cylinder wall.
All models of the Dash 7 Series are powered by a 12-cylinder or 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine carried over from the Universal Series, and have speed-based adhesion control with a multi-channel LED annunciator panel. Dash 7 Series traction motors are powered by direct current.
Nope, a 4 stroke engine only requires a single firing of the spark plug at the start of the power stroke. However, many 4 stroke engines add an extra firing during the exhaust stroke to clean-up any unburnt fuel. This helps emissions but is not a strict requirement of the 4 stroke engine.
According to 2007 Scuderi Group claims, tests indicate that the Scuderi engine shows gains in efficiency and reduced toxic emissions over conventional four-stroke Otto cycle designs. The company also says that the Scuderi engine could be used as part of an air hybrid system, allowing recovered braking energy to be stored as compressed air. [10]
