Improving the efficiency of post-warming up of the engine by dynamic loading

There is a calculated and theoretical justification of the time reduction method of post start engine′s warm up by switching it to the operation mode “free acceleration-coasting”. The working in this mode is cycled with increasing speed range of the crankshaft angular speed as the engine warms up by decreasing the lower limit of steady crankshaft speed to minimum and increasing the upper limit to the allowable maximum safe crankshaft speed at the actual temperature caused by a sharp increase in fuel supply to maximum . The developed method allows you to download the mates of unsteady speeds which increases significantly the efficiency of internal combustion engines in relation to the steady of the state idling mode.
