In the two-cycle engine, there is one power stroke to each up-and-down journey of the piston.
In 1880 he began to commercialize a two-cycle stationary engine.
Thus eight pounds per square inch is about the usual limit of crank case compression with this type of two-cycle motor.
Thus it is plain that the motor is of the four-cycle type and it should not be confounded with two-cycle motors.
This is called a two-cycle motor, because two complete revolutions are necessary to accomplish all the operations.
Atkinson was ingenious and persevering in the invention of two-cycle engines.
It will thus be seen that the piston of the two-cycle motor acts as a pump in two ways.
It certainly cannot become a perfect mixture in the time of a stroke of a high-speed motor of the two-cycle class.
This two-cycle engine later became very popular, especially for motor launch work.
The design shown at D in side and plan views is the conventional form employed in two-cycle engines.
