Our unique patent pending design solves the inherent challenges of pre-ignition, poor cold starting, unbalanced combustion, uneven temperatures, limited RPMs and loads with Homogeneous Charge Compression Ignition or Homogeneous Compression Ignition (HCCI/HCI).

Welcome to Nautilus Engineering


-Flameless Combustion
-No Spark plugs 
-No Direct-Injection

This Changes Everything

Our most advanced engine exhaust valve cooling technology for HCCI/HCI. Cycle to cycle control over exhaust valve temperature, which prevents intermittent transient autoignition events.
