“…Hydrogen contributes H atoms that are expected to improve the auto-ignition of methane [23]. In-cylinder injection of small amounts of diesel, very early in the compression stroke (about 120 BTDC) was effective in lowering the ICT with natural gas [24]. Experiments with small amounts of diesel (2e3% on the energy basis) being injected at about 60 BTDC in a turbocharged diesel engine revealed that HC emissions can be significantly reduced by using hot EGR [25].…”

“…An infrared sensor was used to sense the position of the crank shaft and gives senses to the electronic control unit. The start of the injection and injection duration of the injector were controlled by using the ECU [1], [6], [7], [8]. An electric pump is used for ethanol pressurizing, which operates at 7 bar.…”

“…As in other forms of combustion, this exothermic reaction releases chemical energy into a sensible form that can be translated by an engine into work and heat Contents [3], [6]. Dual fuel engine is an alternative piston-engine combustion process that can provide efficiencies as high as compression-ignition direct-injection (CIDI) engines producing ultra low oxides of nitrogen (NOx ) and particulate matter (PM) emissions.…”

The increasingly strict restrictions being place on diesel engine emissions have the interest in alternative combustion concept. The dual fuel engine exhibits much better emission characteristics than a diesel engine whilst having similar efficiency. The dual fuel engine is investigated for their potential to achieve near zero nitrogen oxide (NOx) and soot-particle emissions. In both SI and diesel engines, the fuel must burn hot to ensure that the flame spreads rapidly through the combustion chamber before a new "charge" enters. In a dual fuel split injection engine, there is no need for a quickly spreading flame because combustion occurs throughout the combustion chamber. As a result, combustion temperatures can be lower, so emissions of nitrogen pollutants are negligible. The fuel is spread in low concentrations throughout the cylinder, so the soot emissions from fuel-rich regions in diesels are not present. As the method for reducing exhaust emissions from diesel engines, a homogenous charge diesel combustion technique is used where by a portion of fuel is supplied into the intake port to form homogenous pre mixture then the mixture is fed into the cylinder port before ignition of the diesel fuel, which is injected directly into the cylinder. The homogeneous pre mixture is prepared with the help of electronic fuel injection.

One of variables, which affect the performance and emission of dual fuel engine is injection pressure. Hence in the present work, effect of Injector opening pressure on the performance of the engine was studied. A four stroke single cylinder engine was modified to work in dual fuel mode. Three injector opening pressures (180 bar, 200 bar and 220 bar) were considered for the present work. Methyl ester of mahua oil was used as pilot fuel and LPG was used as primary fuel. From the test results, it was observed that the injector opening pressure of 200 bar results in higher brake thermal efficiency. The higher injector opening pressure results in better atomization and peneatration of methyl ester of mahua oil. The exhaust emissions such as Smoke, unburnt hydro carbon and carbon monoxide of 200 bar is lower than other pressures.
