Experimental Investigation on Exhaust Emissions With Ceramic Coated Diesel Engine Using Linseed Oil Based Biodiesel

Abstract

Experiments were conducted to determine exhaust emissions in a conventional diesel engine (CE) and ceramic coated low heat rejection (LHR) diesel engine [with ceramic coated cylinder head] with different operating conditions [normal temperature and preheated temperature] of linseed oil based biodiesel with varied injection timing and injector opening pressure. Exhaust emissions [smoke and oxides of nitrogen]. Smoke levels decreased and NOx levels increased with engine with LHR combustion chamber with biodiesel operation. Advanced injection timing, increase of injector opening pressure preheated biodiesel reduced exhaust emissions from LHR engine with biodiesel operation.
