２サイクルガスエンジン
Document Type and Number:
Japanese Patent JP5765819
Kind Code:
B2
Abstract:
An object is to provide a two-cycle gas engine in which generation of NOx (nitrogen oxide) is suppressed by promoting premix of fuel gas with air. A two-cycle gas engine includes a cylinder 2, a cylinder head 3, a piston 4 that defines a combustion chamber "c" with a surrounding wall 2a of the cylinder 2 and the cylinder head 3, a fuel gas injector 8 configured to inject fuel gas 8a, 8b into the combustion chamber "c", an ignition unit 10 configured to ignite the fuel gas inside the combustion chamber, a scavenging port 6 configured to supply air into the combustion chamber "c" upon the piston 4 being positioned in vicinity of a bottom dead center, a fuel gas injection timing control unit 12 configured to cause the fuel gas injector 8 to inject the fuel gas 8b upon the piston 4 being positioned at 10° to 100° before top dead center in an ascending stroke and to cause the fuel gas injector 8 to inject the fuel gas 8a upon the piston 4 being positioned in vicinity of the top dead center, and an ignition timing control unit 12 configured to ignite the fuel gas inside the combustion chamber "c" by the ignition unit 10 upon the piston 4 being positioned in the vicinity of the top dead center.
