This work is a continuation of earlier research conducted on the effects of different combustion chambers on turbulence, combustion, emissions and efficiency for natural gas converted diesel bus engines.
In this second measurement series the engine (Volvo TD102) was supercharged to enable bmep up to 18 bar at λ = 1.6-1.9. Six different combustion chambers were used. The results show that different geometrical combustion chambers, with the same compression ratio (12:1), have very different combustion performance. A high rate of heat release is favorable for lean operation, and the design of the combustion chamber is very important for the knock and misfire limits.
