If a gasoline engine can be run with a lean air-fuel mixture, a considerable improvement is expected in fuel consumption and in exhaust emissions. Especially in the case of automobile use, this effect is remarkable because of a peculiarity in the high frequency usage of engines operating under a partial load. Therefore, investigation of lean air-^fuel ratio combustion has been put foward zealously. But it seems to have been concentrated on aspects of hardware improvements such as the shape of a combustion chamber, the configuration of an intake manifold, etc. This study was attempted under these circumstances as a software approach. It means a real time optimalization control of an air-fuel ratio with the object of maximum indicated thermal efficiency by using an on-line digital computer. as a result of the control operations, an expected improvement was attained.
