Numerical Comparison of HHO and HHOCNG Fuel Performance Analysis with Pilot Diesel Injection

Abstract:

Nowadays, alternative fuels usage is increasing due to limited oil reserves and increasing petrol demands. There are many advantages and disadvantages of alternative fuels when used alone. In this study, alternative fuels with various specifications are mixed in different proportions to tolerate these disadvantages. Hydroxy (HHO) and hydroxy enriched compressed natural gas (HHOCNG) fuel mixtures with pilot diesel injection was used as dual-fuels on a non-modified diesel engine and investigated their performance parameters such as torque (T), power (P), brake specific fuel consumption (BSFC), indicated mean effective pressure (IMEP) and volumetric efficiency (η_v). This study conducted with AVL Boost simulation program and all graphs are plotted to compare HHO and HHOCNG fuel mixtures performance outputs, additionally all results are compared with neat diesel performance values. The general results show that, HHOCNG enrichment has the best improvement values with respect to single HHO enrichment. Overall improvements for BSFC, torque, power and IMEP values of 25 HHOCNG are 4,086%, 1.67%, 4.13% and 3.67%, respectively.
