PL Silnik spalinowy napędzający samochód pracuje z mocą stanowiącą średnio poniżej 50% jego mocy znamionowej. W takich warunkach sprawność ogólna silnika w znacznym stopniu zależy od sprawności mechanicznej. Sprawność ta uwarunkowana jest rozkładem strat tarcia w poszczególnych fazach cyklu roboczego [[...]
EN The car combustion engine usually works with the power below 50% its nominal value. In such conditions the total efficiency of the engine essentially depends of the mechanical efficiency. This kind of efficiency is conditioned on friction losses in all phases of the working cycle [1]. There are meas[...]
