Title:
吸気とアルコールの暖化を備えた、アルコールおよびフレックスエンジンのためのコールドスタート補助システム
Document Type and Number:
Japanese Patent JP5001282
Kind Code:
B2
Abstract:
An internal combustion vehicle cold start control system method is provided. The method includes warming alcohol and air when a door handle is actuated, while the engine is cold and starting an electric turbine connected to an intake manifold. The method also includes actuating valves allowing recirculation of the warmed air through the intake manifold and actuating spark plugs providing an initial warm-up of electrodes and engine cylinders if the temperature is less than 30° C. The starter motor is driven by 2-4 turns of a crankshaft axle so that any cold air in an air filter at the cylinders' entrance is drawn inside and is expelled by the exhaust system. A small volume of the warmed alcohol fuel is maintained in the fuel injectors. The method also includes injecting the warmed alcohol, verifying the minimum air temperature; and deactivating the system after appropriate warm-up of the engine.
