In this article, a single-cylinder, direct-injection, variable-compression-ratio diesel engine is modified into a dual-fuel diesel engine by incorporating a venturi gas mixer at the inlet manifold.Abstract:
Biogas has great potential as a clean alternative fuel for dual-fuel diesel engines. The present work is aimed at investigating the operating parameters such as compression ratio (CR) and injection timing (IT) for a dual-fuel diesel engine run on biogas and rice-bran biodiesel. The motivation behind this investigation is to obtain a diesel equivalent performance together with a reduction in emission. To achieve this, a single-cylinder, direct-injection, variable-compression-ratio diesel engine is modified into a dual-fuel diesel engine by incorporating a venturi gas mixer at the inlet manifold. A set of combinations composed of CRs of 17, 17.5, and 18 and ITs of 23°, 26°, 29°, and 32° before top dead center (BTDC) at different loading conditions are considered. The combination of IT=32° BTDC and CR=18 is found to produce a maximum brake thermal efficiency of 25.88% and a liquid fuel replacement of 82.75% at 100% load. On average, there is a reduction of carbon monoxide as well as hydrocarbon emiss...read more

Hydraulic characterization of Diesel, B50 and B100 using momentum flux
TL;DR: In this paper , a method for different fuels for measurement of injection rate based on the spray momentum measurement and total fuel mass injected is presented, which shows that an increment in injection pressure boosted fuel spray dispersion whereas increment in ambient pressure showed a reverse effect.
