Abstract:

Purpose. Modeling of the engine intake process with a non-traditional power mechanism and improvement of maintenance system and repair of vehicles by adjusting maintenance modes.

Methodology. During the simulation of the intake process of the gasoline engine, theoretical positions based on the fundamental theory of thermal motors, thermodynamics and hydraulics are used. The work of a non-shaft engine was investigated with usage of calculation-theoretical research methods. Experimental studies of the change in the life-cycle of trucks during the exploitation operation were carried out using simulation numerical modeling and road tests at the automobile enterprise. The methods of theory of probability and mathematical statistics, reliability theory are used.

Findings. The mathematical model of the engine intake process with an unconventional power mechanism allows us to evaluate the measures aimed at optimizing the design of the engine and increasing its fuel efficiency. It is simpler, less labor consuming and requires less machine time for calculations compared to conventional models. Algorithms of analysis of truck failures and determination of their rational modes of maintenance (on the example of Volvo vehicles) have been projected. The economic effect of innovations involves reducing operating costs per unit of performed transport and increasing profits.

Originality. The mathematical model of the working cycle of the engine is specified in the part of development of the model of the intake system, which takes into account kinematics of the engine and an alternating degree of compression, which increases its fuel efficiency by 10 %.

Practical value. Measures are developed for controlling the technical condition of the main parts of trucks and their maintenance, taking into account the actual state of the vehicles, which allowed increasing the probability of predicting 10 % of malfunctions. The usage of these measures can increase the technical condition of the mining industry.
