SCIENTIFIC PRINCIPLES AND WAYS OF REDUCTION OF TOXIC CHARACTERISTICS OF AUTOMOBILE SPARK-IGNITION ENGINES

Analytical methods of studying the operation of the engine at deep throttling conditions have been developed, new quality coefficients for the cylinder working charge and the methods of calculating the formar have been introduced, the method of estimating the efficiency of the operation at the above conditions has been suggested by using the criterion of comparing the working charge activeness coefficient with its theoretical values. Methods and designs of the adaptive control systems for engine fuel have been proposed by considering the efficient mixture leaning limits, neutralizer microwave heating and activation of the nitrogen oxide reduction process in the neutralizer through supply of hydrogen to it. The results of the design studies have been introduced at the Volga Automobile Plant (VAZ), and the design solutions developed are used in the engine fuel feed systems of the automobiles made at the VAZ, Gorky Automobile Plant (GAS), Ulyanovsk Automobile Plant (UAZ), Izhevsk Machine-Building Plant (IzhMASH) and Saporozhye Automobile Plant (ZAZ). The results of the work have been used in the educational process.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
