Title:
3サイクル気体燃料エンジン
Document Type and Number:
Japanese Patent JP5065532
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a three cycle gas fuel engine capable of obtaining smooth and strong rotating power.SOLUTION: A rotary stirling cycle mechanism in which three power rotors 6 placed inside a cylinder conduct orbital motion where mutual positional relationship of the three power rotors 6 is not changed, includes: a spark plug 20 on one end side in a short axis direction of a rotor housing 4; an air-fuel ratio controlling means which is provided with an intake port 7 and an exhaust port 8 on the another end side in the short axis direction on both sides of the short axis, and a fuel supply means that supplies gas fuel into a cylinder on another end side of a long axis, which is composed of a direct-injection fuel supply means, and which controls an actual air fuel ratio to a ratio that varies according to operation state by increasing and decreasing air supply amount from a scavenging air supply means; a dilution gas recirculating mechanism which leads circulating dilution gas to a trailing section of an intake actuation chamber; an intake eccentricity mechanism which eccentrically mixes a part of the intake gas to the trailing section of an exhaust actuation chamber; and a metering supply means which effectively lubricates metering oil inside the cylinder.
