Abstract
Development trend in diesel engine is to achieve more power from same size of engine. With increase in brake mean effective pressure (BMEP), the peak firing pressure will also increase. The methodology to control the peak firing pressure on higher BMEP is the major challenge. We achieved better SFC with CPCB II emission targets on a constant speed engine. This study involves a systematic approach to optimize combustion parameters with a cost effective and robust Inline Fuel Injection System.
This paper deals with the strategies applied and experimental results for achieving the power density of 25kW/lit @ 1500 rpm with Inline FIP by keeping lower Peak firing pressure. Various combustion parameters such as Combustion Bowl Geometry, selection of Turbocharger, Swirl, FIP, Nozzle configuration, EGR flow rate, EGR operation strategy, optimizing injection pressures, start of injection, end of injection, injection duration are optimized. The innovative way of Temperature Input based EGR valve operation is used to meet emission at reduced cost and complexity.
This Paper describes Inline Fuel Injection solution for meeting CPCB II emission norms up to 20 bar BMEP level with best in class fuel consumption. With the given solution, it is also observed that the part load fuel consumption values obtained are better than CRDI system. The lower Fuel consumption gives lower operating cost and low CO2 emissions.
