    Coconut oil is very familiar and useful for human civilization. Now-a-days many coconut oil extraction procedures are used. All these process are adapted in large industries. In this project the main concern was to produce coconut oil by using simple extraction process and ensure its perfect quality. In modern coconut oil extraction machine, only copra is used to produce oil, but in this machine, all kinds of coconut can be used to produce oil except baby coconut. In this thesis paper, the design procedure, production process and quality of the coconut oil are described clearly. The construction of coconut oil extraction machine is very simple, small in size and low cost. It is made of stainless steel, mild steel bar and plain sheet. Coconut meat is used as a raw material. In every process coconut meat is heated inside the machine. But here in this machine moisture of coconut meat is removed by using direct sunlight. That is why the nutrition value of produced coconut oil is better. Applications of coconut oil are versatile. It is used for cooking, health care, direct fuel mixed with diesel and producing biofuel. It is also used as a lubricant in the textile industry. Special feature of this extracting machine is that anyone can operate and produce coconut oil easily by this machine. The paper also contains a comparison study of exhaust gases produced by using pure diesel and 15% coconut oil mixed with diesel.
