(57) [Summary] [Object] An object of the large-sized side-injection type methanol engine according to the present invention is to provide a large-sized side-injection type methanol engine which can secure ignition stability and glow plug reliability in a direct injection type engine. To do. [Structure] In a large-sized two-cycle side injection engine that uses only methanol as fuel, main fuel valves 7 and 8 arranged point-symmetrically so as to inject in the direction of the swirl SW, and provided in the cylinder cover U Main sprays Z1, Z2, Z3, Y1, directed toward the engine center EC through the spray guides G1, G2 having the truncated cone shape. It is characterized in that it has a plurality of auxiliary fuel valves 1 and 2 for injecting so as to reach Y2 and Y3 in the shortest distance, and a pair of glow plugs 3 and 4 inserted in pairs in the spray guide. |
