Thermal system simulation and modelling for Alternative Fuels in a Heavy Duty Truck

In the current scenario, demand for Alternate energy source is increasing to reduce dependency on presently available fuels. Internal Combustion engines working on multiple fuels developed in which LNG/CNG is a close contender. Cooling system is one of the critical components of an automobile that influences the engine performance and efficiency. Higher heat demands efficient Cooling system. In this paper an approach is defined to arrive at a Cooling system architecture for CNG/LNG fuel. The aim is to finalise a Cooling system package which is simple and Energy efficient. Modelling is done in Thermal simulation software KULI. Detailed study is done on simulation results of air flow and temperatures and correlated with test results.
