This study introduced the bulk combustion systems instead of the conventional gasoline spark ignition system and diesel compression ignition system. To achieving both high efficiency, without ignition systems to the conventional single cylinder diesel engine, established the inlet-air heating and control systems for the heating and controlling of inlet-air.<br/> The lean limit of air-fuel ratio improved by the inlet-air heating with the compression ignition combustion systems' and the allowable air-fuel ratio extended to 63 when the temperature of the inlet-air was 170 ℃ and the engine speed 1000 rpm.<br/> The cycle maximum pressure and the brake mean effective pressure increased to proportional, when the air-fuel ratio was richer.<br/> The brake specific fuel consumptions increased largely at the air-fuel ratio was above 45 and affected strongly by the inlet-air heating temperature.<br/> The maximum brake thermal efficiency showed at the air-fuel ratio was 35 and decreased in case the leaner region and improved the higher inlet-air heating temperature.<br/> The maximum heat release rate increased in according to decreased and advanced the<br/> accurance period of the maximum heat release rate.<br/> Also, as showed the mass burned rate, the burning period shorted and established the rapid combustion in according to the air-fuel ratio decreasing.<br/>
