Emissions and Performance of Gosoline Engine

概要

論文の詳細を見る
Most emission from automobiles are products of high temperature and high pressure combustion in combustion chamber. The formation of carbonmonoxide and nitric oxide are explained by equilibrium in the combustion reaction, and the quench zone in combustion chamber yields unburned hydrocarbons.<BR>Carbonmonoxide and hydrocarbons can be oxidized in expansion stroke or exhaust systems. The reduction of nitric oxide and particulate emission are most serious problems in exhaust control techniques. The exhaust thermal reactor and catalytic converter have been developed, while it seems that non leaded fuel is necessary to work them effective. Low emission vehicle should appear by 1975, and the power plant of family car still may be gasoline engine. In the near future, the fuel will be subject to more severe restriction in quality to reduce the pollutants in exhaust gas.
