PURPOSE:To obtain high combustion efficiency and excellent fuel consumption by burning air-fuel mixture in a cylinder by use of combustion gas as a primer produced from ignited/burnt air-fuel mixture in the fuel concentrating part. CONSTITUTION:A grounded electrode 32 is opposingly mounted on the edge of a center electrode 31. A air-fuel mixture staying near a fuel concentrating part 39, formed on the piston side, of the grounded electrode 32 is ignited/burnt with a spark between the respective electrodes 31, 32 acting as the first primer. The air-fuel mixture in a cylinder is also burnt with combustion gas of strong intensity acting, as the second primer following, an expansion-turbulence action produce in the fuel concentrating part 39. The initial combustion speed right after ignition can be remarkably accelerated by spreading combustion of the gas in the fuel concentrating part 39 with strong or intensity than the spark between respective electrodes 31, 32. In this way, high combustion efficiency and remarkably superior fuel consumption cna be obtained. |
