Prototype model of diesel engine vibration and noise generation

Influence of noise and vibration to comfort in diesel engine cars running at idle

a bench has been designed and built : it allows that a subject can be placed on a car seat excited in the vertical direction; the subject also has his hand on a vibrating steering wheel and can hear noises through headphones. Thus a realistic simulation of the environment of the driver of an engine car running at idle is possible. After measurements on six cars, three paired comparison tests ha...

Simulation of Small Diesel Engine Vibration using Artificial Neural Network

The use of bio-ethanol as an alternative diesel engine fuel is increasing rapidly. Bioethanol is mixed with diesel fuel in different ratios and used in CI and SI engines. Vibrations have direct effects on engine components and users when the engine is operated on a vehicle. For this reason, analysis of vibration resulting from combustion in IC engines is very important. In this study, evaluatio...

Narayan Time - Frequency Analysis of Diesel Engine Noise

Combustion is the main type of noise radiated from diesel engines. Several methods have been devised to reduce the noise levels. Fourier tranformation methods along with block attenuation curves have been used to study the correlation between cylinder pressure and noise radiated from engines. In this work wavelet method has been used to study noisee mitted from a dual injection diesel engine. T...
