“…Dhole [49] used hydrogen as a secondary fuel for a diesel engine, with good results in terms of thermal efficiency (i.e., a 6 to 10% increase, depending engine load and hydrogen content) and NO x emission level reductions (i.e., a 63% decrease with small engine loads and 32% decrease with large loads) [49].…”

Considering the current environmental restrictions, particularly those imposed on fossil fuel exploitation, hydrogen stands out as a very promising alternative for the power and transportation sectors. This paper investigates the effects of the employment of hydrogen in a K9K automotive diesel engine. Experiments were conducted at a speed of 2000 min−1 with various engine load levels of 40%, 55%, 70%, and 85%; several quantities were monitored to evaluate the performance with hydrogen use in terms of brake-specific energetic consumption (BSEC), fuel economy, maximum pressure, and heat-release characteristics. It was found that at 55% engine load, the engine efficiency increased by 5.3% with hydrogen addition, achieving a diesel fuel economy of 1.32 kg/h. The rate of increase of the peak pressure and maximum pressure started to increase as a consequence of the higher fuel quantity that burned in the premixed combustion phase, while still remaining within reliable operational limits. The accelerated combustion and augmented heat release rate resulted in a combustion duration that was reduced by 3° CA (crank angle degree), achieving a mass fraction burned percentage of 10% to 90% earlier in the cycle, and the combustion variability was also influenced. Hydrogen use assured the decrease of CO2, HC, NOx, and smoke emission levels in comparison with classic fueling.

The present work attempts to determine the optimal engine load, fuel injection pressure (FIP), start of injection timing (SOI) and pilot-main injection intervals (PMII) regarding the performance and emissions of a diesel engine fueled with J20 biodiesel (20 vol% Jatropha curcas biodiesel + 80 vol% 0# diesel). A four-factor and three-level full factorial design and response surface methodology (RSM) were employed in the design of experiments and in the analysis of test results. All the models developed using RSM for measured responses like NO X , Soot, HC, CO emissions, brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) were determined to be statistically significant by analysis of variance. Interactive effects between load, FIP, SOI and PMII were analyzed using tri-dimensional response surface plots that were fitted using developed multiple regression models. The multi-objective optimization was carried out using the desirability-based approach of the RSM for minimum emissions and BSFC and maximum BTE. The best condition of engine parameters with J20 was load of 65.71%, FIP of 160 MPa, SOI of 4.02 CA and PMII of 4.40 CA. And the optimal values with a high desirability of 0.866 were 1172 ppm, 0.0061 FSN, 2.78 ppm, 17.53 ppm, 203.818 g/kW h and 40.96% for NO X , Soot, HC, CO emissions, BSFC and BTE, respectively.
