Early investigation on utilization of Jatropha methyl ester (JME) tyre pyrolysis oil (TPO) blends in a single cylinder, constant speed, direct injection diesel engine revealed that a blend of 80% JME and 20% TPO referred to as JMETPO20 blend give a better performance and lower emissions compared to other Jatropha methyl ester tyre pyrolysis oil (JMETPO) blends. In this study, for further improvement on performance and emission characteristics, and also to find optimum injection timing for blend, experiments have been carried out with varying the injection timing. Tests have been conducted under two advanced and two reratarded injection timings in addition to the original injection timing of 23 °CA bTDC. The experimental test results showed that for the JMETPO20 blend at advanced injection timing of 24.5 °CA the brake thermal efficiency increased by about 2.21%, compared to the result of original injection timing at full load. For the JMETPO20 blend at advanced injection timing of 24.5 °CA the nitric oxide and carbon dioxide emission increased by about 4.56% and 11.91% respectively at full load, and the carbon monoxide emission decreased by about 11.21%, compared to that of original injection timing.

Due to the depleting fossil fuel reserves and increasing environmental concerns, researchers have been studying the effect of adding different types of oils to diesel and more recently plastic oil. The present paper is an experimental study of the effect of compression ratio and injection parameters such as injection pressures and injection timing on the performance and emission characteristics of a variable compression ratio diesel engine fuelled with blends of plastic oil. Various proportions of ethanol and diesel are blended with plastic oils for the preparation of test fuels. It is observed from the experimental study that P90D5E5 blend gives the highest brake thermal efficiency yielding an increase of 16% and 38% compared with pure diesel and pure plastic oil, respectively. Smoke emissions are found to be the lowest for P90D5E5 than diesel and P100. Brake-specific fuel consumption, carbon monoxide and smoke values are reduced for all blends with an increase in injection timing, pressure and compression ratio. Combustion analysis of the blends indicates higher values of cylinder pressures and net heat release rates for P90D5E5 and P100, respectively.


In this world, the population is increased and the number of vehicles increased. Not only population the pollution is increased lot by vehicles in the world harmful pollutant is realized from the vehicles like CO, HC, NOx and smoke particulates. It is inevitable to find some new technology, which increases the better performance and emission characteristics. Partially premixed compression ignition (PCCI) is the best technology for the reducing of harmful pollution in the vehicle, which uses the diesel as fuel it, gives the advantages of both CI and SI engine. This paper investigates the performance and emission characteristics of partially premixed diesel engine. Diesel engine has two injectors of port fuel injector (PFI) and direct injector (DI) to inject the fuel in different timing and electrical control unit (ECU) passes the power to PFI; it can control the injection timing and increases the fuel content from the fuel pump. The main aim in this paper is studied is effect of partially premixed ratio, performance of engine and emission characteristics of diesel engine

The primary objective of this study is to discover the effects of injection timing on performance, emission and combustion characteristics effect of advanced and retarded injection timing of the engine fuelled with mahua oil biodiesel blends. The engine performance, combustion and emission characteristics of the mahua oil biodiesel blends (B20, B40, B60, B80and B100) are investigated in this experimentation without any modification of the diesel engine. At this advanced pressure t he efficiency of engine by means of CO, Unburned HC gases and smoke emissions with higher oxides of nitrogen was observed compared to diesel. The obtained results are compared with a neat diesel and mahua oil biodiesel blends are shown through the graphs. From this study, identifies optimum fuel blend of this work. Thus, the combustion of duration is similar in all variance in pressure. This research paved a way to bio-diesel in mahua oil mixture and draws best outcome in emission less and to maintain eco-friendly environment.
