Abstract Demands for improved fuel efficiency and reduced CO 2 emissions of diesel engines have been the driving force car industry in past decades. One way to achieve this would be by using thermal spraying apply a insulation layer on parts engine’s combustion chamber. A candidate spray process give coatings with appropriate properties is suspension plasma (SPS). SPS, which uses liquid feedstock deposition finely structured columnar ceramic coatings, was investigated work application light-duty engines. In work, different processes materials were explored optimized microstructure head aluminum pistons used engine cars. The functional evaluated single-cylinder experiments. influence thermo-physical their has discussed. coating formation complex piston profiles also results show that SPS can promising technique producing chamber, possibly lead higher
