A Study on Shallow W-Type Combustion System for High-Speed Diesel Engine 910485

The authors of this paper have experimented on four and six-cylinder engines of ϕ 0102 x 125mm with shallow W-type combustion system, showing satisfactory results. In a 1200-2800 r/win speed range the prototype engine showed excellent performance characteristics, moreover, it required less accuracy in making their inlet ports. Based on fuel injection and combustion heat release pattern measured under various matches of combustion chamber, injection system and inlet port, the authors have studied each effect of design parameters on combustion characteristics and put forward the key points for optimum combustion match.
