The efficiency of heating the gasoline engine while working in cyclic mode: acceleration - coasting

The article provides a rationale for a way of increasing the efficiency of the engine post-launch by transferring it to the “free acceleration-coasting” operating mode. The method allows to download the coupling and engine parts by means of inertial forces arising while working on non-braking unsteady speed modes, which significantly increases the efficiency of the post-start heating of internal combustion engines in relation to the steady-state idling. A comparative assessment of the run-out of parts of the main details of the major coupling of the ZMZ-4062.10 gasoline engine during the start-up period in the dynamic capacity mode and at idling is given. It remains completely acceptable and by no means can be considered threatening. It is worth noting that the application of the method is accompanied by an increase in efficiency due to the reduction of the warm-up time and fuel consumption, which makes it reasonable to consider it acceptable for use in automobile operation conditions.
