The authors discuss their mathematical model of in-cylinder heat exchange processes, based on actuating medium heat calculation. The model simulates processes during suction and compression strokes, as well as heat exchange through combustion chamber walls. This contributes into the analyses of engine fuel economy and mechanocaloric load on combustion chamber components vs. coolant temperature.

Investigation results are given, showing that the 2-phase fuel condition is quite typical for most automotive diesel engine fuel systems; we should note that the gas phase at the most operating conditions is not diluted at the fuel injection. The effect of the gas phase on hydrodynamic processes in fuel systems is shown.

A short analysis is described of discharge characteristic variations, relating to two models of national carburettors of series production. Investigation results are considered of the effect of individual dosage element parameters and several carburettor parts as a whole at low expenses. The factor distribution is evaluated, considering their effect on the dosage characteristic variation and recommendations for the variation reduction.

A new method is offered for the assembling of complicated conjugated precision parts. Advantages of this method are considered, comparing with existing methods: increase of the accuracy of the part assembly and a possible automation. A construction and operation are described of a semiautomatic installations for the two-parameter diffuser completion on the diametric clearance and the needle course, using a microcomputer.
