Abstract
In the course of burning, the processes of gas movement intensively occur in the cylinder, which contribute to heat transfer to the cylinder walls. A diesel engine has different heat dissipation conditions than a gas engine. Due to the higher compression ratio, the temperature of the gases leaving the cylinder is much lower. The temperature of the gases in the cylinder in the course of burning reaches 2000-2300 °C. Using methyl hydroxide and changing the installing angles of advancing fuel injection there is a tendency to change the temperature of the cycle in the cylinder of the diesel engine. Starting from a certain position of the piston in the course of the compression stroke, the air temperature becomes higher than the wall temperatures, and the heat flux changes direction, i.e., heat is transferred from the air to the cylinder walls.
