To analyse and research the idle hydrocarbon emission regularity of passenger car gasoline engine, based on large sample detected data of different type cars, parameter estimation and hypothesis test are carried on by statistical tools and neans, and the optimum distribution parameters of idle hydrocarbon emission of different type engines are also got. Then the optimum distribution models of these engines are established. The calculating result shows that the maximum error between model calculating and sample detecting certification rates is only 0.526 8%, and the established models have very high calculating precision and practical value. On the other hand, the research also shows that the inspect and maintenance program should be strengthen in order to control vehicle emission pollution effectively.

A novel approach is proposed for precise control of two-phase spray evaporative cooling for thermal management of road vehicle internal combustion (IC) engines. A reduced-order plant model is first constructed by combining published spray evaporative cooling correlations with approximate governing heat transfer equations appropriate for IC engine thermal management. Control requirements are specified to allow several objectives to be met simultaneously under different load conditions. A control system is proposed and modeled in abstract form to achieve spray evaporative cooling of a gasoline engine, with simplifying assumptions made about the characteristics of the coolant pump, spray nozzle, and condenser. The system effectiveness is tested by simulation to establish its ability to meet key requirements, particularly concerned with precision control during transients resulting from rapid engine load variation. The results confirm the robustness of the proposed control strategy in accurately tracking a specified temperature profile at various constant load conditions, and also in the presence of realistic transient load variation.
