Experiments will be conducted with baseline gasoline and later with dual fuel mode of experiments i.e., gasoline with LPG with different ratios (25%, 50%, 75% and 100% of LPG by mass). Experiment will be carried out with varying speed from 2000 rpm to 4500 rpm in steps of 500 rpm at full load condition with factory set static ignition timing of 5 deg. bTDC to investigate combustion characteristics and cyclic variations. Results revealed that as the LPG percentage increases the peak pressure also increases and it is maximum for 100% LPG for all the speed. At 4500 rpm the percentage increase in peak pressure is 20% for 100% LPG, 9% for 25%LPG, 3% for 50%LPG, 1% for 75%LPG when compared to gasoline at full load. This increase in peak pressure will indicate the LPG will give better combustion properties compared to that of gasoline. Compared to peak pressure, the variation in cycle to cycle for IMEP is less.Net heart release rate shows that gasoline will give the more heat release compare to all other fuels, but LPG will release the heat little earlier than gasoline. Since peak pressure is near to TDC for LPG which results in NHRR to occur earlier than gasoline. Final outcome of the research is LPG will have better combustion properties compared to gasoline but cyclic fluctuations are more for LPG.

Biomethane is induced along with the intake air stream while diesel fuel is injected in a conventional way. Experiments were carried out on an exhaust gas recirculation (EGR)-equipped CI engine (single cylinder, four stroke, water cooled). The main goal of this investigation is to study the combustion characteristics of a biomethane–diesel fuel combination in dual fuel mode of a CI engine. The EGR system is also used in the dual fuel mode of operation to determine its effects. Cylinder pressure, rate of pressure rise, and heat release are the combustion parameters examined. Experimental results showed that all combustion parameters give lower values in the dual-fuel mode of operation compared to straight diesel operation. EGR again reduces the values of combustion parameters in dual-fuel mode.

For this purpose, the conventional carbureted SI engine is modified into an electronically controllable engine, wherein an electronically controllable unit was used to control the ignition timings and injection duration of gasoline. The tests were conducted with different spark timings at the wide open throttle position and 3000 rpm engine speed. The experimental results demonstrated that brake mean effective pressure and engine brake thermal efficiency increased first and then decreased with the increase in spark advance. Peak cylinder pressure, temperature and heat release rate were increased until 20% hydrogen addition and with increased spark timings. NOx emissions were continuously increased with the increment in both spark timings and hydrogen addition, whereas hydrocarbon emissions were increased with spark timings but decreased with hydrogen addition. CO emissions were reduced with the increase in spark timing and hydrogen addition.

Its energy content per unit mass and higher heating value is almost about three times that of current fossil fuels. Hydrogen ignites across a wide range of concentrations, from about 4 to 74 percent, and only requires a small amount of energy to initiate ignition. Moreover when hydrogen reacts with oxygen to generate energy, the resulting reaction product is water vapor.

In India, tons of poultry litter is damaging the fields due to uncontrolled disposal of poultry litter as fertilizer. It also contributes to the emission of greenhouse gases namely methane and carbon dioxide thus polluting the atmosphere. About 100 tons per day manure can be collected which can be used as fuel source at the location selected. With this amount of fuel available, energy can be generated in the cogeneration power plant. ost feasible of this work that can be implemented in cogeneration power plant in sugar factory.

The experiments were conducted in two stages. In stage I, the test fuels were prepared using 99.9% pure ethanol and gasoline with a cycloheptanol blend, in the ratio of E69.5 + 0.5 cycloheptanol, E64.6 + 0.4 cycloheptanol, E59.7 + 0.3 cycloheptanol, E49.8 + 0.2 cycloheptanol. The remainder was gasoline. In stage II, the test fuels were prepared using 99.9% pure ethanol and gasoline with cyclooctanol blend, in the ratio of E69.5 + 0.5 cyclooctanol, E64.6 + 0.4 cyclooctanol l, E59.7 + 0.3 cyclooctanol, E49.8 + 0.2 cyclooctanol. The remainder was gasoline. Performance and emission tests were conducted on a multi -cylinder SI Engine coupled with an eddy current dynamometer. The emission tests were measured using an exhaust gas analyzer. The experimental results proved that the blend increased brake thermal efficiency more than a sole fuel, such as gasoline. The emission tests found that the CO slightly decreased, while HC and O 2 increased moderately and CO 2 and NO x appreciably decreased. In addition, combustion analyses were made with the help of combustion analyzer, in which cylinder pressure and heat release rate were analysed.
