Abstract

In
this study, the effects of boron based thermal barrier coating (Fe₂B
and NiCrBSi) on the performance and emission of a single cylinder diesel engine
were investigated.  In the coating
process of the engine parts, two difference methods were used. Cylinder liner
and valves were coated with solid boronizing and the top surface of the piston
is coated with plasma spray method. Boron layer (Fe₂B) and NiCrBSi
have low thermal conductivity and high thermal resistance. So that, the
combustion chamber of diesel engine was converted in to insulated form. Tests
were carried out under 5 speeds (1800-2100-2400-2700-3000
rpm) of diesel engine. commercial D-2 was used as test fuel. Coated (CE) and
standart engine (SE) test results were compared. Comprehensive analyzes have
shown that brake specific fuel consumption (BSFC) was reduced by 11 %, in the
CE. On the other hand, CO and HC emissions of the CE decreased by 33-17 %,
repectively. And NOx emission increased by 14 % .
