According to the simulation results, compared with the original engine, the fuel saving rate map of the 2/4-stroke switchable secondary expansion IC engine was made by combining the high fuel saving rate conditions of the 2-stroke and 4-stroke working modes. The experiment results showed that the fuel consumption of the engine working on the 4-stroke secondary expansion mode was lower than that of the original engine. Though mechanical wizardry the energy produced by this is used to propel a car forward. Yes, while the engine is firing, a combustion process is taking place. In May 1876, Nicolaus Otto built the first practical four-stroke piston cycle internal combustion engine.He continued to develop his four-stroke engine after 1876 and he considered his work finished after his invention of the first magneto ignition system for low voltage ignition in 1884. And the name basically explains what happens within the engine while it is running. A GT-Power simulation model was established as the supplement of the experiment to evaluate the 2/4-stroke switchable secondary expansion IC engine. Well, to the layman, an internal combustion engine is simply the engine they have that powers their car. A traditional 4-cylinder gasoline IC engine was transformed into a secondary expansion IC engine, however, without the valve time switching device, its expansion cylinder could only work on the 4-stroke working mode. The 2-stroke secondary expansion mode has great advantages in high load condition on both fuel efficiency and power output, but it is not suitable in low load condition, so the 4-stroke secondary expansion is applied to maintain the high energy conversion efficiency in the low load condition. For 100 years the four-stroke internal combustion engine has been the dominant automotive powerplant, but there is a pressing need to improve fuel efficiency, emissions and power density beyond what can be achieved through fine-tuning this. The expansion cylinder could switch its working mode between 2-stroke and 4-stroke to perform different secondary expansion modes just by varying the valve timing. Alternatives to four-stroke engines promise an increase in efficiency.

The 2/4-stroke switchable secondary expansion IC engine is a 4-cylinder engine with two combustion cylinders and two expansion cylinders. The secondary expansion means the burned gas, after working in a traditional 4-stroke combustion cylinder, is transferred into another cylinder to expand again.
To develop an internal combustion (IC) engine with high energy conversion efficiency, simple structure, and high reliability, a 2/4-stroke switchable secondary expansion IC engine concept is proposed in this paper.
