Title: Study on the Noise of a Hydrogen-Diesel Dual-Fuel Engine
Keywords: Noise, Sound pressure level, Diesel dual-fuel cycle

Abstract: Abstract. Presented in the present paper are the experimental results related to the influence of hydrogen fuel on the noise of a single-cylinder diesel engine operating on a dual-fuel cycle. The variations in the engine noise are assessed by measuring the sound pressure level with four sound-level meters, with microphones positioned one meter from the engine. Registered, further, is also the in-cylinder pressure rise rate. It should be noted that the study is performed at an engine speed of n = 2000 min-1. Made, additionally, is a quantitative assessment of the sound pressure level and maximum in-cylinder pressure rise rate variation while operating on a dual-fuel cycle with hydrogen. The evaluation is performed by comparing the engine noise and the maximum in-cylinder pressure rise rate as a function of both the percentage of the hydrogen content mass ratio at constant mean effective pressure and the mean effective pressure at constant hydrogen content mass ratio.
