Active Coolant Deaeration System for Advanced Turbocharged Engine
Problem statement
Coolant deaeration is a significant challenge on advanced down-sized turbocharged engines. The initial coolant fill of a complex network of internal engine cooling passages and hoses can result in air pockets that must be vented. Furthermore, hot spots in the engine may result in localized boiling, where active venting is required to extract the vapor from the cooling passages. The goal of this projects is to use analytical and lab test methods to design a network of interconnecting deaeration lines for such an engine. The solution must strike a balance between competing engineering constraints – to have enough continuous vent flow to extract air and vapor bubbles from the cooling passages without exceeding the flow limits of the pressurized hot bottle, which is the collection point for all air in the system.
