“…The NOx emission behaviour for all the fuels was found to be similar at lower load with a slight increase in its magnitude at higher load. This is because at lower load, the adiabatic flame temperature of stoichiometric air/ ethanol flame is slightly lower [24]. The overall NOx emissions levels in DFC with 10% EGR is found to be lower due to burning of fuel takes place under lean premixed conditions that results in lower temperature.…”

However, many initial trails to adopt this technology were crude, leading to excessive diesel/biodiesel usage, over fuelling to achieve acceptable power levels, and unacceptably high emissions [24][25]. The present research is aimed to reduce the emissions from diesel engines by operating the engine in dual fuel mode.…”

“…NOx levels increased advanced injection timings(IT) for all fuel combinations in DF mode. The improved combustion and higher HRR during premixed combustion may leads to formation of higher NOx [24]. These higher NOx levels are possible to control by adopting EGR technique.…”

Effect of combustion geometry on combustion, performance and emission characteristics of CI engine using simarouba oil methyl ester N Keerthi Kumar, T K Chandrashekar, N R Banapurmath et al. (NOx) and smoke are mainly formed. In this study a diesel engine having single cylinder is converted into dual-fuel engine to operate with pilot injection of Diesel/biodiesel ethanol blend and Compressed natural gas (CNG). The engine was operated on both single fuel(SF) and dual fuel(DF) mode. The CNG was inducted into the inlet manifold through a gas carburettor on purpose designed for this application. The injection timings was optimized for CNG-biodiesel. The optimum injection timing was 27 o BTDC. The pilot fuel injection pressure was maintained at 230 bar. Engine was operated with optimum Compression ratio of 17.5 and CNG flow rate was optimized and found to be 0.5 kg/h. The effect of CNG induction on combustion and emissions characteristics of a compression ignition engine with a dual fuel was studied and compared with single fuel operation. Comparative results revealing the effect of dual fuel combustion on the engine performance, combustion and exhaust emissions. Based on the performance, combustion and emission characteristics it is concluded that, use of CNG in the dual fuel mode in a diesel engine improves the performance and reduces the exhaust emissions from the engine except for HC and NOX emissions.

“…And CO 2 emission was also reduced at low speed. R.S Hosmath [7] Studied how the injection timing is effected on dual engine functioning with honge oil methyl ether [HOME] and CNG. Maximum BTE of 28.7% at rate of 0.6 KG/hr of BTDC is obtained for DF Engine operation but it is lower than HOME operation and the low CO emission are observed at 26% with the rate of 0.6 Kg/Hr and 27 BTDC compared to HOME operation.…”

This Paper shows the effect of port fuel injection pressure of CNG in 3-cylinder SI Engine at Wide Open Throttle position using sequential port fuel injection system. All trials are performed on 4-stroke, 796 cc MPFI S.I engine at injection pressure of 2.0, 2.2, 2.4, 2.6, 2.8 bar for constant speed of 2500, 3000, 3500, 4000 & 4500 rpm. During the trial compression ratio is kept constant at 9.2 with Maximum Brake Torque (MBT) spark timing of 15 o BTDC. Optimum torque is obtained for CNG at injection pressure of 2.6 bar and 3000 rpm. Gasoline trials are performed at same compression ratio for comparison with CNG at same injection pressure. Performance and emission characteristics with combustion analysis are performed at optimum injection pressure of 2.6 bar.

“…Various gaseous fuels such as biogas, producer gas, hydrogen, LPG and CNG (Compressed Natural Gas) are suitable for Internal Combustion Engines [4]. But LPG and CNG are considered better alternatives because of their simpler structure with low carbon content, resulting in reduction of exhaust emissions drastically [5]. When CNG was used as fuel in automobiles, it results in lower carbon monoxide and particulate matter emission as compared to diesel operation.…”

In the present work experiments were done on a modified LPG Diesel dual fuel engine with diesel as primary fuel and liquefied petroleum gas as secondary fuel by providing a venturi at the inlet manifold for better performance at all loading conditions. The engine was run at different operating conditions and in each case the optimum combination fuel energy proportions were determined for best efficiency. The exhaust smoke level, temperature, and other emission parameters were measured. The results were compared with the performance of the engine with diesel as sole fuel, and as dual engine without modifications and specific conclusions were then arrived. It was concluded that the brake thermal efficiency slightly reduces with modified design in comparison with conventional design. Diesel consumption is reduced considerably and also CO and HC emission are slightly higher at lower loads and reduces with increase in load. Smoke density and NOx are reasonably reduced in the modified design with LPG flow rate of 0.3 kg/hr found to be optimum in all conditions.
