Topic: Adiabatic Compression

A caller disputes the safety of propane and butane blends in automotive systems, citing the risk of adiabatic compression causing internal ignition within the compressor. Proponents of the hydrocarbon blends argue that the auto-ignition temperature is approximately 1630 degrees Fahrenheit, which is classified as non-flammable under certain Australian mining standards. The debate centers on whether the frequency and consequence of potential fires constitute an acceptable risk compared to the toxicity of government-mandated coolants.
