Abstract The faster depletion of fossil fuels and rapid increasing cost of the petroleum fuel are the main reasons for this experimental investigation to arrive at an alternative fuel for the present diesel engines. Many researchers have submitted their work and succeeded with 20 % volume of biodiesel fuel with diesel at various ambient conditions. The alphabet “P” refers to Pongamia, which is best suited for the Indian climate and can be cultivated even on a nonagricultural land. The other biodiesels under research are Jatropha, Karanja, Neem, Mahua, Karanja, cotton seed oil, etc. In India, the edible oil is used for cooking; it is decided to use nonedible oils for the research. Out of the total energy produced in compression ignition (CI) engines, one third of heat energy alone is used for useful work as the remaining energy is rejected to coolant and surrounding. To retain the heat energy in the combustion chamber a thermal barrier coating for a thickness of 0.5 mm is applied on the top surface of piston and bottom surface of cylinder to retain the heat energy. The ceramic material preferred for coating is partially stabilized zirconia (PSZ). The tests were conducted with Diesel as the reference fuel and 20 % Pongamia biodiesel blended with diesel (P20) as the test fuel. The results were compared and a discussion has been made with suitable justifications. Compromising results were obtained for brake thermal efficiency (BTE), specific energy consumption (SEC), hydrocarbon emission (HC), and carbon monoxide emission (CO). Nitric oxide (NOx) emission is higher in the experimental work, for which the suitable means have been discussed in the scope for the future work. Keywords Biodiesel • Thermal barrier coating • PSZ

1 Introduction The intensive research is an urgent requirement for the replacement of conventional petroleum diesel as the depletion rate is more day by day. Use of vegetable oil is already demonstrated in the 1900 in an exhibition at Paris by Rudolf Diesel [1]. He demonstrated the engine with peanut oil. Since the vegetable oils have higher viscosity, it leads to a poor combustion and further exhibits poor performance characteristics. The emission characteristics of the biodiesel blends indicate that the blends provided a good alternative to conventional diesel. Experimental investigation with Waste cooking oil study showed that Waste Cooking Oil methyl esters have similar properties with diesel fuel [2]. Transesterified vegetable oil, which is known as biodiesel has lesser viscosity and can be com
