Summary:

An optically-accessible single cylinder small-bore HSDI diesel engine equipped with a Bosch common-rail injection system is used to study the effects of differing injection strategies on combustion and soot. Laser-Induced Incandescence (LII) is used to visualize the evolution and distribution of soot within the combustion chamber from the onset of ignition to late into the expansion stroke. A low-sooting fuel, blended from two single component fuels, is used for experimentation. Because of the low-sooting nature of the fuel blend, the lean operating conditions, and optical distortion of the complex shaped engine, acceptable LII signal levels are difficult to obtain. Therefore a low-sulfur European Diesel fuel is also employed during experimentation. Acceptable LII signal levels are obtained using the Diesel fuel, however, without extreme caution, surface damage to the optical components of the engine are possible. The objectives of this paper are to document the difficulties of performing LII within Diesel engines with realistic bowl geometries while operating under low-sooting conditions
