ROTARY ENGINE

摘要

A rotary engine is provided to use a hydrogen gas as fuel in a rotary piston engine to provide good performance and reduce manufacturing cost of the rotary engine. A rotary engine includes rotary pistons(1,2), ignition plugs(3), a cylinder block(4), a rotary piston shaft(5), a cylinder residual gas exhaust port(6), a hydrogen mixed gas suction port(7), an combustion gas exhaust port(8), and rotary piston blades(9,10). The rotary pistons have projection blades. The blades are rotated in the rotary piston engine housing to be folded to prevent collision of the blades. When the engine is operated for a long time, a timing gear is worn to generate friction between the blades. The timing gear is formed of a wearing resistance material.
