Abstract
A method and apparatus for starting a cold internal combustion engine under optimum conditions. Engine r.p.m. is maintained to a desired value until either the car is started, driven, or the temperature of the engine reaches a predetermined value, whichever first occurs. During this time, the ratio between the air and fuel fed to the engine is kept at the optimum values corresponding to the prevailing engine conditions during this time.
