This paper deals with a two-stroke cycle Hythane engine with poppet valves on the cylinder head. The characteristics of two-stroke engine are high power and high torque from low revolutions range. But general two-stroke engines have problems of air pollution due to HC emission at scavenging process or consumption of lubricating oil. This two-stroke engine with poppet valves was improved from a four-stroke engine to solve their problems. The engine adopted direct injection to prevent short-circuit loss of fuel. The Hythane was adopted as fuel. The Hythane is fuel added hydrogen to methane in order to improve the combustion delay and ignition delay of methane. As a result of experiment, the power with the Hythane which contained 20% hydrogen was better than it with the Hythane which contained 15% hydrogen was obtained.
