Abstract

Investigations were carried out to study exhaust emissions of a medium grade low heat rejection (LHR) diesel engine consisting of air gap insulated piston with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions [normal temperature and pre–heated temperature] of linseed biodiesel with varied injection timing. Exhaust emissions of particulate emissions and nitrogen oxide (NOx) levels were evaluated at different values of brake mean effective pressure (BMEP) of the engine. Comparative studies were made with conventional engine (CE) with biodiesel and also with diesel operation with similar working condition. The optimum injection timing was 31o bTDC (before top dead centre) with conventional engine while it was 29o bTDC for engine with LHR combustion chamber with biodiesel operation. Particulate emissions decreased while NOx levels increased with engine with LHR combustion chamber with biodiesel in comparison with CE.
