AN EXPERIMENTAL STUDY ON INTERNAL COMBUSTIONNOISE AND EXHAUST GAS RECIRCULATION OF A DIRECTINJECTION DIESEL ENGINE OPERATING ON ETHANOL

摘要

The following conclusions can be drawn from the experimental work reported here:1. Increasing content of ignition improver gives decreased noise emissions due to decreasedignition delay, peak pressure and lower rising rate. Incxwtsing content of Avocet would causelower NOX emissions, but it was found a minimum for 2% Avocet. Probably because of thenitrogen content in Avocet.
