In this paper, the effects of formaldehyde addition on the performance of compressed natural gas homogeneous charge compression ignition engine, CNG (HCCI) were investigated. In this study, the four-cylinder, four-stroke engine was used. The results obtained from the use of various percentage of formaldehyde addition in CNG (HCCI) engine were compared to those of numerical and theoretical analysis. The results indicated that when addition fuel additive as the formaldehyde in CNG engine were used, engine performance parameters such as torque and power, brake mean effective pressure and brake specific fuel consumption are optimum condition at 0.13% formaldehyde addition in CNG (HCCI) engine and these parameters are decreased with increasing more than 0.13% formaldehyde addition amount in the engine. It is also shown that the air/fuel mixture will ignite earlier using this additive so it is conceivable to reduce inlet mixture temperature resulting in better performance due to higher volumetric efficiency
