Key words:
engines.
Results arc given of the action factor analysis, showing that the free turbulence is the most important in the heat exchange in the engine exhaust manifold at the valve closed. Its effect is enforced by the natural convection and pressure pulses in the manifold. The calculation dependence is given in order to evaluate the non-stationary heat exchange, it is attained from experiments on the muffling channel model, dynamic engine model and the engine.
