In this research, the air intake and exhaust systems in internal combustion deck’s engine are investigated and the volumetric efficiency as a major impact on effective power of deck’s engine is studied comprehensively and thoroughly. Some of the parameters affecting the volumetric efficiency were studied such as air pressure, air temperature, compression ratio, residual gas pressure, variation of temperature, compressor temperature and fuel air ratio individually. This was done through the aid of computer program using the MATLAB environment. The effects of those parameters were varying on the volumetric efficiency, where air pressure, air temperature and compressor temperature were having a proportional effect on the volumetric efficiency and effective power. On the other hand, the compression ratio, variation of temperature, residual gas pressure and fuel air ratio were having an inverse effect. As conclusion, the maximum value of volumetric efficiency (86%) and the corresponding effective power was attained due to the effect of compressor temperature. The minimum value of volumetric efficiency was (62%) due to the effect of increasing the fuel air ratio.
