We have done the research in the field of increasing the performance of internal combustion engines by improving the works processes. We proposed a method for carrying out research and development work, providing solution to the problem. We carried out the analysis of the relationship of teamwork crank and valve train mechanisms reciprocating internal combustion engines. We proposed a mathematical model of gas exchange processes specifying assumptions. Constructed a mathematical model based on the principle of sharing the basic equations of isotropic and unsteady gas dynamics. Consider the problems of the cylinder, intake and exhaust. The problem of the cylinder placed in the form of open-equilibrium thermodynamic system. The problem of the intake and exhaust considered in quasi-one setting. Justified using gas exchange dynamics benchmark for selection of rational design of valve train mechanism internal combustion engines. The possibility of numerical evaluation of the effectiveness of the variable valve timing in the process of purging the cylinder are considered. Conclusion about the necessity of simultaneous variable valve train, intake and exhaust working fluid.
