Popis:	In this article, the effects of thermal barrier coated combustion chamber on the single cylinder direct injection diesel engine with dual biodiesel (combination of pongamia pinnata oil and neem oil) are experimentally investigated. The piston surface and cylinder head of the diesel engine are coated with Aluminium Titanate. The two biodiesels are mixed with diesel in various proportions and their performances are examined by using both base engine and low heat rejection engine. Specific fuel consumption of coated engine (CE) with diesel--pongamia pinnata--neem 1 (DPN 1) fuel (mixture of diesel 75%, pongamia pinnata oil ethyl esters 22.5%, and neem oil ethyl esters 2.5% by volume) is 13.9% lower than the baseline engine. The brake thermal efficiency of DPN 1 CE is 11.9% higher than baseline engine. Smoke opacity and hydrocarbon emission from CE are lower than the baseline engine. The DPN 1 CE emits 16.6% lower smoke than the diesel fuel in baseline engine. However, nitrogen oxides and carbon dioxide emissi...
