“…With high percentage of alcohol in the blends, the HC, CO emissions could increase and the BTE might be slightly reduced but the use of 5% blends could reduce the HC and CO emissions as well. Gnanamoorthi and Devaradjane [16] investigated the influence of compression ratio on the performance, combustion, and emission characteristics of a single cylinder 4-stroke direct injections naturally aspirated Diesel engine powered by diesel-ethanol blends. Compression ratios such as 17.5:1, 18.5:1, and 19.5:1 were considered and varied by altering the dimensions of piston bowl by keeping the standard stroke volume.…”

The paper presents results of co-combustion of diesel-biodiesel-ethanol fuel blend in direct injection Diesel engine. Test was performed at constant rotational speed at three commonly used loads of this engine: 100%, 85%, and 70% of load. During the test hydrated ethanol was used at a concentration of 89% of alcohol. In this study, the ethanol fuel was added to diesel-biodiesel fuel blend with concentrations up to 50% with the increment of 5%. The biodiesel was used as an additive to prevent the stratification of ethanol and diesel blends. Thermodynamic parameters of engine were analyzed, and combustion process and exhaust emission were characterized. It turned out that with the increase in engine load is possible to utilize larger ethanol fraction in blend. With the increase of ethanol fuel in blend the increase in ignition delay (38.5% for full load) was observed, but burning duration decreased (49% for full load). The ethanol fuel share in blend generally causes the increase in NO x emission (42% for full load) due to higher oxygen content and higher in-cylinder temperatures. It turned out that, at full load the unrepeatability of indicated mean effective pressure was near the same up to 50% of ethanol fuel in blend (about 2%). In case of partial load at higher ethanol fuel fraction the increase in indicated mean effective pressure un-repeatability was observed.

“…Gnanamoorthi and Devaradjane[26] demonstrated an improved performance of their diesel139 engine with the use of higher CR along with ethanol blended diesel fuel. Sharma and 140 Murugan [27] examined the effects of varying the CR at optimum injection timing and nozzle 141 opening pressure on the behaviour of a diesel engine by using a blend of 80% biodiesel, and 142 20% oil obtained from pyrolysis of waste tyres.…”

“…They found that NO x emission reduced marginally when compression ratio reduced from 18.40:1 to 16.00:1. Gnanamoorthi and Devaradjane [174] experimentally investigated the effect of compression ratio (17.5:1 to 19.5:1) on engine performance, emission and combustion characteristics of ethanol-diesel fuelled engine. They found that increasing compression ratio have positive impact on engine performance and combustion but increases NO x emission.…”
