An adiabatic engine was constructed with the monolithic type ceramic material. A highly durable and superior heat insulating engine could be completed, through detailed study of the design, evaluating the ceramics of which reliability is inferior in strength, going back to the microstructure and improving it to the utilizable level as the engine parts.
I started studying the combustion in a bid to accomplish improvement of the fuel consumption rate, realization of multi-fuel engine and pollution-lowering, but I found out that recovering of the ignition delay shortening can be coped with by high pressure injection, fuel nature modification and so forth.
In future, I have to pursue my studies in connection with reduction of emission of exhaust gas like the NOx and recovery of energy from the exhaust gas, and the similar subjects.
