A fluid flow regulator of the present invention comprises in combination a stationary hollow duct housing having a first end and a second end through which fluid flows. The device also incorporates a movable member aligned concentric with the duct having an end essentially similarly shaped and sized to the first end of the housing. The member may be spaced apart from the duct so that fluid can enter the duct housing through an opening defined by the space between the end of the member and the first end of the duct, with the movement of the member serving to change the size of opening. The movement of the member is controlled by the movement of a float located within the duct. The position of the float can be preset by the operator of the invention so that when fluid flow into the duct is at a predetermined amount the float will remain stationary, and when the fluid flow increases above such predetermined level the float will be moved in the direction of the fluid flow and when fluid flow into the duct is below said predetermined amount, the float will move the member opposite the direction of fluid flow.

A poppet valve engine incorporates a single rotary combustion chamber serving multiple cylinders to decrease emissions and increase thermodynamic efficiency. Virtually zero emissions are achievable by on-board fuel reforming to hydrogen. Limited heat range exposure of the rotary combustion chamber, low temperature combustion, and ceramic coatings reduce heat loss while three stage combustion, intake and fuel preheating, and fuel reforming reduce combustion process irreversibility. A supercharger increases the power density to allow engine displacement reduction. A z-crankshaft assembly coupled with a pre-combustion chamber allow knock-less and stable hydrogen combustion at virtually all load and speed conditions. Variable compression, possible in certain configurations of the z-crankshaft assembly, further increases thermal efficiency.
