Method for cold start of Engine Fueled with alcohol and system for cold start of Engine Fueled with alcohol. A method for comprising a trigger an internal combustion engine 10 under cold condition. The regulating valve of the intake manifold 36 is kept closed and the ignition spark is suspended.The fuel and the air are admitted into the cylinders 14, 44 and the pistons 16 are rotated by a plurality of revolutions. During each cycle of revolution of the engine, the fuel / air mixture is compressed and heated 44 way by arivador adiabatic engine power engine, and the mixture is expelled at the exhaust manifold 28.During the overlap of the valve, a portion of the mixture is carried to the cylinder and compressed again in the next cycle. The additional fuel can be injected to replace the fuel lost. After several cycles of the engine, the ultra - violent fuel / air 44 become heated to a temperature above the flash point of the mixture.The spark is restored to burn the mixture heated and the regulating valve inlet 36 is reactivated. The first combustion can produce enough heat to keep the combustion mixture for spark of the recently introduced after that.
