Numerical Research Engine Coolant Temperature and Flow Rate Effect on the Engine Cold Start

To study the influence of LNG fuel supply system on engine cooling system, ensure that the engine cold start performance, an AMESim based LNG fuel supply system simulation model with the key components of vaporizer was proposed. By analyzing the influence of the coolant temperature and flow rate on the phase transition of LNG, and worked out the ranges of temperature and flow rate in vaporizer when the engine reached normal operating. It has a strong significance to the design of LNG fuel supply system.
