Abstract
The influence of the number of nozzle holes, turbocharging and an oxidizing catalytic converter in an ethanol fuelled spark-assisted diesel engine (SADE) is investigated. Emissions, brake thermal efficiency and other performance parameters are measured and compared with the base-diesel model. The results show that a SADE equipped with a 7-hole injector nozzle and an oxidizing catalytic converter reduces HC and CO emissions drastically at low load, and meets the ECE-49 exhaust emissions standard. Additionally, the SADE exhibits superior brake thermal efficiency at high loads. The brake specific HC and CO emissions are superior to the base-diesel model and the engine operates on lean mixtures at all speeds and loads.
