The currently reported work was concerned with experimental and numerical evaluation of the potential to partially replace diesel with hydrogen fuel, which continues to attract attention as an alternative longer-term fuel solution. The experimental work was involved with the fumigation of hydrogen on a single cylinder HD diesel engine under two real-world driving conditions at low and mid loads. Highest practical hydrogen substitution ratios could increase indicated efficiency by up to 4.6 and 2.4% while reducing CO 2 emissions by 58 and 32% at low and mid loads, respectively. Soot and CO emissions were reduced as more hydrogen was supplied, particularly at low load. The numerical study was made by using two distinct phenomenological models being run in parallel. While, an in-depth evaluation of the unique dual fuel combustion was possible, the arising errors were largely associated with lack of dual fuel burning velocity data, which will remain a key barrier to dual-fuel simulation.

“…A similar trend is found with the peak cylinder pressure for 13-40% loading condition, and a decrease in pressure is recorded for loads greater than 80%. HRR was found to decrease for both the fuel blends as compared to normal diesel operation (Dhole et al, 2016). An experimental validation was provided for the NOx model generation of H 2 -diesel DF engine.…”

PurposeThe different performance tests were conducted on diesel engine compression ignition (CI) mode and CRDi engine.Design/methodology/approachThe CI engine was suitably modified to CRDi engine with Toroidal re-entrant combustion chamber (TRCC) and was run in dual-fuel (DF) mode. Hydrogen (H2) was supplied at different flow rates during the suction stroke, and 0.22 Kg/h of hydrogen fuel flow rate (HFFR) was found to be optimum. Diesel and biodiesel were used as pilot fuels. The CRDi engine with DF mode was run at various injection pressures, and 900 bar was found to be optimum injection pressure (IP) with 10o before top dead center (bTDC) as fuel injection timing (IT).FindingsThese operating engine conditions increased formation of oxides of nitrogen (NOx), which were reduced by exhaust gas recycle (EGR). With EGR of 15%, CRDi engine resulted in 12.6% lower brake thermal efficiency (BTE), 5.5% lower hydrocarbon (HC), 7.7% lower carbon monoxide (CO), 26% lower NOx at 80% load as compared to the unmodified diesel engine (CI mode).Originality/valueThe current research is an effort to study and evaluate the performance of CRDi engine in DF mode with diesel-H2 and BCPO-H2 fuel combinations with TRCC.

“…To reduce the moistness, the gas was entranced to a sandbed filter (6) to clean again. Finally, the gas was inducted by the blower (8) to compress into a Y-shape mixing chamber and an intake manifold of diesel-engine generator (7). Properties of producer gas are shown in Table II.…”

“…In addition, Reference [7] increased the ratio of hydrogen mixed with producer gas as secondary fuel while diesel fuel was injected into the engine as primary fuel at constant speed and various loads. Increasing hydrogen combined with producer gas gave the combustion characteristics better than the use of only producer gas combined with diesel fuel on dual fuel mode.…”

The objective of proposed work is to present about engine performance and emissions analysis of a diesel engine using the diesel fuel and the supercharging producer gas in dual fuel mode compared with only diesel fuel mode. Producer gas is generated from a small downdraft gasifier 75 kW using a charcoal as the primary fuel. Results of performance and emissions at engine speed 1,600 rpm show that using diesel fuel and supercharging producer gas at various flow rates in dual fuel mode increase the electrical power and electrical efficiency and decrease the energy consumption. Carbon monoxide, hydrocarbons and black smoke emissions increase with increasing producer-gas flow rate. Compressing producer gas at 125 lpm indicates that there is the highest diesel saving at 40% on engine speed of 1,200 rpm.
