Název v původním jazyce

Measuring Mechanical Losses of Piston Combustion Engine by Spinning at Various Working Pressures in Engine Cylinders

Popis výsledku v původním jazyce

This work deals with the measurement of mechanical losses by spinning on a test station. It is the current widely used procedure for detecting the effect of various measures to reduce mechanical losses in the piston combustion engine. From the point of view of mechanical losses on the piston group, these measurements show, as the main deficiency, a greater difference between cylinder pressure at engine spinning and cylinder pressure in standard engine operation (i.e. combustion of the mixture). A new way of measuring passive resistances by spinning on a test station in the laboratory of the Department of Vehicles and Engines (DVE), Technical University of Liberec (TUL) eliminates the above-mentioned deficiency for the most part by the fact that even when spinning it is possible to increase the pressure in the cylinder by means of a proportional pressure valve on the values common during normal operation of the engine.
