Time-Resolved Analysis of Soot Formation and Oxidation in a Direct-Injection Diesel Engine for Different EGR-Rates by an Extinction Method 952517

The formation of soot during the first phase and the oxidation of soot during the later phase of the combustion in a direct-injection diesel engine have been investigated in detail by an extinction method. The experiments were performed in a 1.9 l near-production high-speed four-cylinder in-line direct-injection diesel engine for passenger cars for different rates of exhaust gas recirculation (EGR) and for different fuels. The measurements result in crank angle resolved and cycle-averaged soot mass concentrations in the piston bowl and the combustion chamber.
The results show that with increasing EGR-rates the amount of soot formed is increased only slightly but the amount of soot oxidized during combustion decreases significantly. This is assumed to be the main reason for the increase of soot in the exhaust gas with increasing EGR-rates.
