Author Name:

Abstract:
ABSTRACT Investigations were carried out to study exhaust emissions of a high grade low heat rejection (LHR) diesel engine consisting of air gap insulated piston with superni (an alloy of nickel) crown, air gap insulated liner with superni insert and ceramic coated cylinder head with different operating conditions [normal temperature and pre–heated temperature] of linseed biodiesel with varied injection timing and pressure. 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) and 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 28o 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. Key Words: Crude vegetable oil; biodiesel; exhaust emissions; LHR combustion chamber.
