    Abstract: The paper discusses the experiences to design the piston used in the CNG gas engine and gives some analysis on the main points that should be taken care especially while designing the piston concerning the characteristics and application of CNG engine.An example is given herein to present the design process of CNG piston.It is introduced how to modify the heavy-duty diesel piston into that part that should be applicable for natural gas engine. What this test dissertates is the development of natural gas engine piston which was reconstructed from the heavy diesel engine piston.
