Engine load impact on maximum value of normal force in piston mehanism

Abstract

Working machines are an indispensable part of agriculture. Until today, all working machines, as a power engine, use the IC engine. Unlike the engines for the passenger cars, the engines for the working machines are exposed to more extreme working conditions. The normal force is known that have greatest impact on the cylinder wearing, and as such reduces engine life. An experimental determination of the pressure value in the cylinder of the engine was carried out for the cultivator engine. Measurement was performed for three different engine speeds at four different loads. On the basis of the obtained pressure, the values of the maximum normal force that act in the piston mechanism are calculated. As a result it is obtained relation between the maximum value of the normal force and engine load.
