Dynamic Thermal Equilibrium Test and Analysis of the Small Gasoline Engine

Abstract

To research the relationship between the coolant heat power and engine working conditions, and to guide the reasonable design of all heat-radiating components, an experiment method of heat balance at all operating modes was developed and implemented for a certain type of small gasoline engine. Based on the multivariate regression analysis, the correlation between the coolant thermal power and the engine rotation speed and torque was obtained. Tested by the experimental results and significant approach, the multivariate regression equations established have a high precision, and a certain theoretical and practical value for the cooling system analysis and design for small gasoline engine.
