The goal of the existing investigation is to research the impacts of the minor enlargement of benzyl liquor, classified one at a time as aliphatic and fragrant sort alcohols depending on the classified hydroxyl collecting function in their sub-atomic shape. Lemon grass and diesel mixtures (B25 and B50) had been organized and attempted to take a look at the CI engine execution, discharge and burning attributes under zero burden conditions. To each one of the four mix gasoline checks organized for B25 and B50, benzyl liquor introduced substances were included at 1% - 5% fixations with the aid of quantity. Test assessments for the general public of the diverse powers had been accomplished in a multi chamber, 4-stroke and regular pace CI motor and the motor attributes have been contrasted and diesel and bio gas mixes. The exploratory exam uncovers that the bad execution of B25 and B50 is upgraded with benzyl liquor (Bn) growth. The development in execution is substantial with an expansion in the centralizations of liquor in B25 and B50 mixes. Higher HC, CO and smoke outflows related with B25 and B50 mix fills emanations are dwindled with liquor compulsion. The end result of this exploration paintings is that poor burning attributes of the bio gas- diesel mix may be progressed with the minor enlargement of aliphatic and aromatic liquor. Higher NOx emanations, benzyl liquor verified promising outcomes as a long way as execution parameters like productiveness, discharge and ignition improvement.

Work has been carried out using four stroke single cylinder diesel engine with retrofit attached with fuel injector and at optimum injection pressure 210 bar and 230 BTDC. The main purpose of using retrofit is to achieve HCCI (Homogeneous charge compression ignition) with which emissions can be reduced. Four Variants of retrofits were used and with V-cut type retrofit it was found that there is reduction in toxic emission like CO and NO but there was slight increase in HC emission when compared with normal fuel injector. Engine performance was compared with normal injector and injector with V-cut and it was found that Break thermal efficiency was increased by 0.25% at full load and 1.53% at 80% load and specific fuel consumption decreased by 0.01%.

In this investigation high FFA CRBO a renewable non-edible vegetable oil was tested to find its suitability as a CI engine fuel in its blended form. A dilute blend was prepared by mixing it with petroleum diesel in volume basis [20% CRBO + 80% No.2 petroleum diesel]. The main objective of this investigation is to study the performance and emission characteristics of this high FFA CRBO blend by employing it as a fuel for diesel engine. Tests were conducted on a naturally aspirated DI stationary diesel engine coupled to a swinging field dynamometer. Emissions were measured by using MRU Delta 1600 L gas analyzer. Variations in the emission of UBHC, CO, NOX and smoke density were found for different loads and compared with diesel. It was observed that when operating with CRBO blend, engine emissions levels are reduced significantly than that of diesel. When compared with diesel fuel, NOx emission, UBHC emission and smoke density for CRBO blend were lower with slight increase in CO emissions. It was also observed that the variations in brake thermal efficiency between CRBO blend and diesel were minimum at all operating conditions. From the experimental results it can be concluded that as a dilute blend higher FFA CRBO has an ability to replace petroleum diesel partially as the engine emissions were reduced significantly with minor loss in power.

In this present paper, an attempt has been made to examine the performance and emission characteristics of a single cylinder diesel engine fueled with blends of mixed biodiesel (Thevetia peruviana, Neem, Jatropha, Pongamia). Experiments were conducted with various blends of mixed biodiesel in CI engine for different loads. The results show that lower brake thermal efficiency and higher brake specific fuel consumption were obtained with mixed biodiesel blends when compared with diesel. Lower the value of CO and HC and higher the value of CO2 emissions were determined for mixed biodiesel blends compared to that of diesel. Also, higher in NOx and lower smoke opacity were found compared to diesel.

Experimental study is focussed the performance and emission characteristics of a compression ignition diesel engine using biodiesel and biodiesel mixed with aluminum oxide nanoparticles as an additive in different proportions. The aluminum oxide nanoparticles promote complete combustion in the diesel engine. The experiments were conducted using biodiesel (B100) with aluminum oxide nanoparticles additive in proportions of BN100, BN200, BN300, BN400 and BN500 ppm at different brake power. Results were analyzed and compared with diesel, biodiesel, biodiesel with addition of aluminum oxide nanoparticles. Gas analyzer was used to measure the various gas pollutants. The test results showed that the addition of aluminum oxide nanoparticles with biodiesel has improved complete combustion of the fuel leading to better performance and reduced exhaust emissions like CO, HC, smoke and NOx when compared to diesel fuel.
