Novel Exhaust system architecture for Petroleum Oil Tanker Application vehicle

A large amount of heat given off by ATS on BS-VI exhaust system vehicle. Heat shield is required to protect the surrounding components. As per PESO (Petroleum and Explosives safety organization) guidelines for POL Application vehicle is that,(i)the surrounding temperature should not be more than 180° C and (ii) there is no spillage of any petroleum product to the bare surface of exhaust part directly. In BS-VI vehicle the heat given off from ATS is higher than the BS-IV vehicle. Typically flexible or wrap around heat shield is provided over ATS. In BS-VI flexible heat shield is not possible as more sensors and components are coming. In this project the novel design of heat shield (combination of flexible and metallic sandwich) on exhaust system is used. This design ensures the surrounding temperature is below 180° C and there is no spillage of petroleum product to the bare surface of exhaust parts (Including Tail pipe, Exhaust main pipe and ATS) directly. Also this design protect the internal components as well as external sensors, cables by removing heat smoothly from heat shield.
