Abstract

Reducing noise and vibration emissions, which are the most important factors affecting driving comfort in diesel engine vehicles, is an important issue. It seems possible to reduce these emissions by adding renewable fuels to diesel fuel. The main purpose of this study is to reduce engine vibration and noise emissions by mixing ethanol and isopropanol fuels with diesel fuel. In the experimental study, 7% ethanol (D93E7) and 7% isopropanol (D93IP7) were added to the pure diesel fuel to reduce vibration and noise emissions caused by the use of standard diesel (D100) fuel. The experiments were carried out at two different loads (3-6 Nm) and at four different speeds (1000-1500-2000-2500 rpm). When the test results are evaluated in general; In the tests performed with D93E7 fuel at 6 Nm load and 2000 rpm, it was determined that vibration emissions decreased by 26% compared to D100 fuel and noise emissions decreased by 2%. On the other hand, in tests performed at low load (3 Nm) with D93I
