Abstract

There are currently 4 types of compressed natural gas (CNG) tank. As the type number increases the typical weight decreases. Type 1 tanks are a formed steel or aluminum which typically have a protective coating around them. Type 2 tanks use a steel liner around the volume which is surrounded by a partial composite material ‘wrap’ in the middle of the tank. Type 3 tanks are typically made with an aluminum liner and a full composite wrap. Type 4 tanks have no metal, instead using plastic with a rubber liner and a composite wrap around the natural gas. The goal of the project is to analyze the optimum pressure of the type 4 CNG tank by using finite element analysis. The software selected is SolidWorks. A new design of the tank will be drawn and undergo pressure simulation to analyze the optimum pressure. The new design idea is taking from the REL conformable tank by applying the same material but however a different design of the tank structure. The project objective is to design a CNG tank with improvement in the volume of the compressed natural gas to solve the weakness of the current natural gas vehicles problem. Since, the volume of the compressed gas is inversely proportional to the pressure of the compressed gas while the temperature of the compressed gas remains constant according to Boyle’s Law. The other objective is to free up the cargo space by using the underneath space of the truck.
