Improvement in thermal efficiency and reduction in emission from diesel engines are major thrust research work in all around the world. This research work is on the performance and emission characteristics of diesel engine using Low Heat Rejection (LHR) techniques of thermal barrier coated cylinder liner and piston. A piston was coated as 100 micron thickness and three cylinder liners were coated in the thickness of 100,150 and 200 micron. Piston and cylinder liners were coated with equal percentages of Alumina and Yittria Stabilized Zirconia powder using the plasma spraying coating method. The test results compared with base engine showed reduction in the performance parameter of specific fuel consumption (SFC) on an average by 6.11%, 12.78% and 16.89%, while the brake thermal efficiency increased by 1.68%,3.75% and 5.19% in 100,150 and 200 micron thickness coated cylinder liner used engine respectively. There was reduction in Carbon monoxide (CO), unburned hydrocarbon (HC) and smoke emissions levels while Nitrogen Oxide (NOx) emission was slightly higher in the coated engine compared with the uncoated engine in all load conditions. Overall, 200 microns thickness coated cylinder liner showed a better performance parameter and low emission compared with other cylinder liner coated engine.

Performance And Emission

In present days industries are growing at a rapid rate and so as the usage of the diesel. The fossil fuels are limited in nature, the increased usage of diesel is resulting in the depletion of its reserves this gives rise to the need of alternative fuels. Due to low specific fuel consumption and supreme power efficiency it has vast applications compared to other fuels but NOX and smoke has seriously causing problem to environment. For this the Palmyra oil has same properties of diesel with varying compression ratios effects the performance and emission characteristics are evaluated. In this process step wise increase of CRs from 16 initially .Then increases EGRs of 0%,5% and 10% and studied performance and emission characteristics. There is improvement in engine efficiency during EGR increment and at low load .There is simultanesly decrease in NOX emissions . The single cylinder four stroke variable compression performance and emissions can be varied.. when fuel is pure diesel,b15and b35 of Palmyra oil is examined and bear with standard automobile usable diesel was conducted at compression ratio of 16:1 at the degrees of 19 and 23 degrees. The influence of Palmyra oil like compression ratio on fuel consumption ,brake thermal efficiency and exhaust gas emissions like NOx and hc has been investigated .the overall optimum is found to be b15 biodiesel –diesel blended for compression ratio of 16 at different exhaust gas recirculation such as 0, 5 and 10. The same experimentation is done for other blends B15 and B35 with palmyra oil. All the values are compared with each other. The configuration which achieved highest Break thermal efficiency is compared to the common diesel engine configuration used and the advantages and the disadvantages are listed out

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 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.

The present work examines the oxygen enrichment on diesel engine at the fuel side and air side. Oxygenation at the fuel side is done by blending the Dimethyl carbonate (DMC) additive with a maximum percentage of oxygen whereas that of air side is done by coupling a blower to the inlet manifold. The experiment was conducted with four different blends of oxygenated additives with diesel, and then the effects of supercharging in these blends were analyzed. The performance and emission characteristics of DMC blend with diesel fuel were examined and compared with the base engine characteristics. The results show that for 5% of DMC there is an increase in the thermal efficiency of the engine and decrease the CO emissions.

Performance And Emission

To meet the challenges of increased energy need and concerned about environmental friendly, renewable fuels are being explored in the current energy scenario. In the present study non edible Linseed oil was used as alternative source for diesel engine fuel. The physico-chemical properties were evaluated and compared with mineral Diesel and found in close resemblance. The fuel was tested by using performance and emission parameters on an unmodified single cylinder diesel engine. The study was done by using diesel & Diesel-linseed oil blends at various loads from no load to 100% loads with interval of 20%. The linseed fuel was blended into 5%, 10%, 15% and 20% v/v ratio with neat diesel and compared with baseline data of neat diesel operation. Performance parameters such as brake thermal efficiency and brake specific fuel consumptions were studied and emission parameters such as CO (carbon mono oxide), UBHC (unburned hydrocarbon), NOx (oxides of nitrogen), CO2 (carbon di oxide), exhaust temperature were measured. The thermal efficiency of the engine was lower and the brake specific energy consumption of the engine was higher when the engine was fueled with Linseed oil-Diesel blends compared to diesel fuel. Emission characteristics are better than diesel fuel. NOx formations, using various fuel blends during the whole range of experiment were lower than diesel fuel. The results from the experimental study suggest that the linseed oil could be a potential substitute for diesel engine in the near future as far as small and medium energy productions are concerned.
