THE PROBLEM OF CONTAMINATION OF ENGINE PARTS

This article considers the problem of formation of deposits on the parts of internal combustion engines. Describes the main types of deposits in engines and reasons for their formation. The analysis of influence of oxidation of motor oils on the technical condition of internal combustion engines. The author offers a brief description of the program-methods of laboratory research of engine oils, including the evaluation of changes in properties of motor oils in contact with different concentrations of diesel fuels

Influence of parameters of the liquefied petrol gas’ state on the time of a gas’ discharge from the automobile gas cylinder

The article is devoted to the current problem - safe, civilized discharge of liquid phase of the hydrocarbonic, propane, butane gas from the automobile gas cylinder. For implementing this condition there is described the functional diagram of the modernized system of supplying engine with gas in case of using the cylinder with a multivalve. There are presented results of investigating thermodynamic indexes of liquid and steam phases, characterizing the process of discharging liquefied petrol gas from the automobile gas cylinder. The regularities of changing parameters of liquefied petrol gas’s condition from the outer air’s temperature are revealed
