PURPOSE:To prevent the burning of an engine by detecting the temperature immediately before the burning of an engine while operating an increased fuel supply mechanism through said sensor and supplying a super dense mixture gas. CONSTITUTION:When an engine will overheat, the bimetal valve 23 in a bimetal valve switch 21 will bend reversely. Consequently the casing 22 and a pressure conducting pipe 20 are conducted to lead the positive pressure in a crank case 3 through the casing 22 and the pressure conducting pipe 20 into the pressure receiving chamber 18a of a diaphragm chamber 18. Consequently the diaphragm 17 will flex and a gate valve 16 will close the air path 15. As a result the air through an air bleed hole 14 will not be mixed with the fuel sucked through a needle jet 9, to produce the super dense mixture gas thus to promote the cooling of the engine. |
