Abstract
Diesel engines’ performance and emissions characteristics may be greatly enhanced by effective heat transfer control. In this work, the heat transfer losses in a CI engine running on PM5 and PM10 blends ternary fuel combinations made of diesel, methanol, and 1-pentanol, are examined. The goal is to assess these blends’ potential for lowering heat losses and improving engine performance by adding nanoparticles. The convective and radiative heat transfer coefficients, blowby volume flow rates, and total blowby losses for PM5, PM10, and diesel under various engine loading situations were examined through experimental research. The comparisons and trends between the fuel mixes and diesel were clearly seen in the data. In terms of convective heat transfer, PM5 exhibited slightly higher coefficients than diesel at low load conditions, but lower coefficients at higher loads. Moreover, PM10 consistently demonstrated lower convective heat transfer coefficients than diesel across all loading conditions. Except at 75% load, where it showed higher coefficients, PM5 typically showed lower radiative heat transfer coefficients than diesel. At all loading circumstances, PM10 consistently shown lower radiative heat transfer coefficients than diesel. Following the trend of cylinder temperature, blowby volume flow rates for PM5 and PM10 were typically lower than those for diesel. However, except at 75% load, PM5 demonstrated greater overall blowby losses per cycle than diesel. Diesel exhibited higher overall blowby losses than PM10. According to the results, both PM5 and PM10 blends might decrease heat transfer losses in CI engines, which could boost thermal efficiency. The examination of losses due to heat transfer in a CI engine running on a combination of PM5 and PM10 fuel, in summary, sheds light on the potential for these fuel mixes to enhance engine performance. The results lay a foundation for further investigation and the creation of innovative fuel mixes for improved engine performance and lower emissions. They also contribute to our understanding of the features of heat transfer in CI engines.
