Abstract Experiments are performed on a diesel engine working in single fuel mode using fossil diesel (FD) as well as 5% and 10% (v/v) di-ethyl ether (DEE) additives with FD as fuels as well as in dual fuel mode using the above fuels as pilot fuels along with producer gas (PG) as primary fuel. This study aims to draw comparative analyses of engine combustion, performance and emission characteristics using the above fuel combinations to establish the most suitable fuel strategy for a diesel engine. The study revealed greater control over nitric oxide (NO) and smoke opacity in dual fuel mode compared to single fuel mode operations. Addition of DEE with FD, produced lower HC and CO emissions, comparable NO emissions along with reduced smoke opacity compared to FD in both modes of operation. Further, in dual fuel mode operation, the diesel percentage energy substitution (PES) reduced with increase in DEE content in the blends. The tradeoff study involving engine performance and emissions with respect to the cost of operation revealed that the fuel strategy used in dual fuel mode operation delivered better engine performance along with reduced NO emission and smoke opacity at lower operational cost compared to all the considered fuel strategy in single fuel mode operation. Especially, FD+5% DEE+PG and FD+10% DEE+PG fuel strategies were found to be the most suitable dual fuel mode combinations in a diesel engine in terms of their superior engine performance, lower emissions along with better economy.

Engine Performance And Emissions

An experimental investigation has been carried out to compare the performance and emissions of a low-compression-ratio Euro 5 diesel engine featuring high EGR rates, equipped with different injector technologies, i.e., solenoid, indirect-acting, and direct-acting piezoelectric. The comparisons, performed with reference to a state-of-the-art double fuel injection calibration, i.e., pilot-Main (pM), are presented in terms of engine-out exhaust emissions, combustion noise (CN), and fuel consumption, at low–medium engine speeds and loads. The differences in engine performance and emissions of the solenoidal, indirect-acting, and direct-acting piezoelectric injector setups have been found on the basis of experimental results to mainly depend on the specific features of their hydraulic circuits rather than on the considered injector driving system.

Engine Performance And Emissions

The present study is investigated on the performance and emissions characteristics of a diesel engine fuelled by compressed natural gas and base diesel (CNG + Diesel). The CNG fuels used as the primary fuel, and diesel as pilot fuel under dual-fuel mode. The pilot fuel is partially replaced by CNG at a different percentage. The primary fuel is injected into the engine with intake air during the suction stroke. The experimental results reveal the effect of CNG + diesel under dual fuel mode on BTE, BSFC, CO, CO2, HC, NOx and Smoke. It is observed from the experimental results that CO2, NOx and Smoke emissions decreased but HC and CO emissions increase with an increase in CNG energy share.
