This paper presents the development of a MCVIT (mechanical continuous variable injection timing) system for evaluating effects of injection timing – one of the efficiently experimental methods for improving diesel engine performance and emission characteristics to match modern emission regulations and bio-fuels. A MCVIT system has been designed and built with the ability to adjust freely and directly the injection timing for a wide range from 0 to 40°CA BTDC (before top dead center) while keeping the same injection pressure rate. Some experiments have been done to verify its significant specifications such as friction torque – speed curve, accuracy and stability. The results show that the maximum friction torque of this system is around 2.6N.m over range of engine speed and its maximum deviation is ±1.0°CA over a large range of testing injection timing. Preliminary study on VIKYNO RV215-2 agricultural small diesel DI engine has also proved that the engine performance and emission characteristics are directly influenced by injection timing. Thus the developed MCVIT system is an efficient and low cost tool for R&D activities in small diesel engines.

In the view to maintain ecological balance, downtrend in availability of petroleum-based fuels and stringent pollution norms have triggered to search for an alternate fuel for internal combustion engines. Present work is to study the influence of IT (Injection Timing), IOP (Injector opening pressure) and number of holes in nozzle on the performance and emission characteristics of diesel engine fueled by Rice bran Oil Methyl Esters (ROME) is reported. For a 5-hole nozzle, IOP at 240 bar obtained the highest brake power of about 28%. Gradual upturn of peak pressure was observed when the IOP was varied from 210 bar to 240 bar.

Fuel Injection Timing

The conventional diesel fuels are depleting at a faster pace. To reduce the burden on the economy, the reserves and sources for future has to be limited. The use of biodiesel derivatives from various sources and its blends in diesel engine has gained more importance in recent years. The present work investigates the feasibility of using dairy scum methyl esters (DSOME) of B20 blend in a modified single cylinder of common rail direct injection (CRDI) engine at a constant speed. Experiments were carried out at different injection timings from 25deg BTDC to 5deg ATDC with constant injection pressure as 600 bar. The fuel injection timing plays an important role in evaluating the performance, emission and combustion characteristics of the engine. The results show that the performance is improved with retarded injection timings compared to the operation of single cylinder DI engine fuelled with DSOME B20 biodiesel.
