Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
THERMACTOR Systems: Operation: Notes
Inlet air to the air pump is drawn through a centrifugal air filter fan. The pump then supplies air under pressure to the exhaust port near the exhaust valve, by either an external air manifold, or through internal drilled passages in the cylinder head or exhaust manifold. The oxygen in the fresh air, plus the heat of the exhaust gases, causes further oxidation (burning), which converts the exhaust gases into carbon dioxide and water.
