Engine Cooling & Environment

3 days MOT/REFEM-E
  • Engineers and technical staff from engine design and testing involved in thermal behavior and energy management, including cooling system designers.
  • To give participants the knowledge related to engine thermal behavior and the vehicle energy management through “external” cooling systems.
Learning Objectives
  • To know the main associated stakes.
  • To be able to implement a new engine in a new vehicle.
  • To know how to quickly size the cooling system and suggest the required trade-offs.
  • Engine fundamentals knowledge would be better.
Ways and means
  • This training uses simple exercises of cooling system sizing, giving orders of magnitude.
  • Clear progression from simple cooling loop up to very complex thermal management of hybrid electric vehicles.
  • In parallel many components, new, used or faulty will be circulated.
  • The last 0.5-day is dedicated to simulation of various in-use situations.

Engine cooling and external circuits 0.4 day
  • Engine cooling requirements, cooling systems types, convection air system, induced air system, liquid system.
  • Engine heat balance, thermal power to be evacuated.
  • Automotive liquid cooling circuit architectures, engine internal component (water pump, thermostat), external components (exchangers, fans, ...), split-cooling, coolant, non-automotive applications.
Impact on vehicle - How do the internal components work? 0.4 day
  • Cooling air circuit: air inlet, electric fan.
  • Coolant circuit: main radiator, engine oil cooler, transmission oil cooler, EGR cooler, passenger compartment heater core, charge air cooler, expansion tank, degassing tank.
Control and driving - Approach to energy management 0.5 day
  • Control parameters: temperature, pressure, flow.
