Transients in engine speed and torque, CO, NOx, HC.


Growing interest in quantifying and reducing the amount of engine emissions of CO, HC, and NOx loading the environment has led to increasingly tighter environmental regulations. Non-road emission standards are performed according to a steady-state test cycle, which does not include transient effects of emissions and thus underestimates the amount of emissions produced in real use of the engine. This study shows the effects of transients in engine speed on the fuel consumption and emissions in Multi- Cylinder diesel engines. Fuel consumption and emissions from the engines were measured in an engine dynamometer during various transient load conditions. The results showed that during fast transients, the measured fuel consumption was large. The effects of transients on emissions of nitrogen oxides were even greater, as effects of transient load increase with increasing transient conditions. In this study increasing in load there was increasing in fuel consumption NOx, HC and CO emissions.
