More cost-effective than high altitude simulation test chambers.

ETC’s Altitude Simulation System is a uniquely designed environmental simulation system that is engineered to accurately simulate high altitude conditions at the induction air and exhaust side of the engine being tested. The Altitude Simulation System is comprised of a Combustion Air Unit which provides air at precisely controlled environmental conditions and a Pressure Control Unit controls the pressure drop of the engine intake air through the use of a valve and vacuum blower system. These reduced pressure conditions are also created for the engine exhaust creating a more cost-effective solution to your high altitude simulation test needs.

ETC’s Altitude Simulation System is considerably more cost-effective than high altitude simulation test chambers, which have gained the attention of the racing industries, heavy duty diesel and many automotive original equipment manufacturers and tier suppliers. New vehicle design and performance verification requires extensive testing where performance verification is done under extreme environmental conditions with stringent accuracy and repeatability requirements. ETC’s Altitude Simulation System can satisfy these requirements as well as the requirements of the Environmental Protection Agency’s NTE emissions envelope.

The Altitude/Pressure Control System performs tests at the following conditions:

  • Altitude Simulation – Sea level to 30,000 ft. (±100 ft.)
  • Boost pressure simulation up to 3 psi above barometric pressure (± 0.01 psi)
  • Optional pressure control configuration designed to deal with drafting and other engine air intake velocity variations
  • Precisely controlled environmental conditions through the use of a Combustion Air Unit
  • Modular components providing easy installation in existing spaces
  • Easily adapted – retrofit existing chambers or test cells
  • Repeatable test results

Applications for the Altitude Simulation System:

  • Gasoline Engine R&D
  • Diesel Engine R&D
  • Cold Start Testing
  • Fuel Economy Testing
  • Aircraft Engine R&D
  • Induction System R&D
  • Power Testing
  • Turbo Charger and Aftercooler R&D
  • Emissions Testing
  • Steady and Transient State Testing
