Exhaust Surge Tank System for Octane Test Engines

The Water-Cooled Exhaust Surge Tank System includes a Flex Exhaust Manifold, a Surge Tank and the Cooling Water Spray and Drain System, those are connected with the octane test engines. The Exhaust Surge Tank System is used for eliminating resonance pulses and back pressure during octane rating operation.Resonance pulses and back pressure may affect the stability of knock intensity signal.
Eliminating the interference of the variables makes the octane test result more consistent and accurate.
Meanwhile, this exhaust system can effectively reduce noise and air pollution.

SINPAR FTC-M2 Octane Test Engines are equipped with the Water-Cooled Exhaust Surge Tank System as a standard configuration.
