Impact of Fixed Injection Timing on Exhaust Emissions with Ceramic Coated Diesel Engine Using Linseed Oil Based Biodiesel.

Research for decreasing the escalating costs of fuel; minimize the exhaust emissions in internal combustion engines and technological innovation studies have been continuing. In this paper, 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 pre-heated temperature] of linseed oil based biodiesel with fixed 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. Increase of injector opening pressure and preheated biodiesel reduced exhaust emissions from LHR engine with biodiesel operation. Increased combustion chamber temperature of ceramic coated internal combustion engines causes a decrease in soot and carbon monoxide emissions.
