Journal ArticleDOI
Effect of fuel injection timing and pressure on combustion, emissions and performance characteristics of a single cylinder diesel engine
Avinash Kumar Agarwal,Dhananjay Kumar Srivastava,Atul Dhar,Rakesh Kumar Maurya,Pravesh Chandra Shukla,Akhilendra Pratap Singh +5 more
TL;DR: In this paper, a single cylinder research engine was used to experimentally determine the effects of fuel injection strategies and injection timings on engine combustion, performance and emission characteristics, and the experiments were conducted at constant speed (2500-rpm) with two FIPs (500 and 1000 bars respectively) and different start of injection (SOI) timings.
Journal ArticleDOI
Effect of fuel injection pressure and injection timing of Karanja biodiesel blends on fuel spray, engine performance, emissions and combustion characteristics
Avinash Kumar Agarwal,Atul Dhar,Jai Gopal Gupta,Woong Il Kim,Kibong Choi,Chang Sik Lee,Sungwook Park +6 more
TL;DR: In this article, the effect of 10, 20, and 50% Karanja biodiesel blends on injection rate, atomization, engine performance, emissions and combustion characteristics of common rail direct injection (CRDI) type fuel injection system were evaluated in a single cylinder research engine at different start of injection timings and constant engine speed of 1500 rpm.
Journal ArticleDOI
Production of biodiesel from high-FFA neem oil and its performance, emission and combustion characterization in a single cylinder DICI engine
TL;DR: In this article, the performance, emission and combustion characteristics of this biodiesel and its various blends with mineral diesel were compared with baseline data in a direct injection (DI) diesel engine.
Journal ArticleDOI
Performance, emissions and combustion characteristics of Karanja biodiesel in a transportation engine
Atul Dhar,Avinash Kumar Agarwal +1 more
TL;DR: In this paper, the effect of Karanja biodiesel (Karanja oil methyl ester; KOME) and its blends on engine performance, emissions and combustion characteristics in a direct injection compression ignition (DICI) engine of a medium size utility vehicle with varying engine speed and load has been investigated.
Journal ArticleDOI
Experimental investigations of performance, emission and combustion characteristics of Karanja oil blends fuelled DICI engine.
Avinash Kumar Agarwal,Atul Dhar +1 more
TL;DR: In this article, performance, emission and combustion characteristics of Karanja oil blends (K10, K20, K50 and K100) with mineral diesel were investigated in unheated conditions in a direct injection compression ignition (DICI) engine at different engine loads and constant engine speed (1500 rpm) vis-a-vis baseline data from mineral diesel.
