Ambient air is fed through a double wall pipe exhaust and subsequently directed into a pintle regulated Venturi. Fuel is vaporized and mixed homogeneously with air in the Venturi throat. The mixture is homogeneous at all throttle loadings because the pintle flow regulating valve maintains a high velocity at the Venturi throat. Water is injected into the Venturi throat to regulate the air/fuel charge temperature and, consequently, auto-ignition timing for a Homogeneous Charge Compression Ignition (HCCI) engine.
