| Zusammenfassung: | The present invention relates to a piston engine whose expansion stroke is greater than compression stroke, belonging to the field of piston engine technology. It is mainly characterized by adding expansion stroke of piston engine and making it be greater than compression stroke, and utilizing residual energy (pressure) in original cylinder to continuously apply work so as to raise engine efficiency and reduce noise of exhaust pressure of engine. Its concrete method lies in that a negative compression process and negative compression recovery process are added. Said method is applicable to various engines. |
