Precision air, matched to demand.
Hansen Engine Corporation develops the patented Hansen Variable Displacement Supercharger ® — delivering exactly the airflow an engine needs, at the moment it needs it, with the waste engineered out.
An engine laboratory, not a slide deck.
Since 1977 Hansen Engine has conceived, designed, fabricated, and tested advanced engine technologies in its own Minnesota laboratory — the kind of patient, hands-on research that produces issued patents rather than press releases.
Technology
A continuously variable, positive-displacement supercharger that supplies pressured air precisely as driver demand changes.
Capabilities
Design, fabrication, assembly, and dynamometer testing under one roof, supported by a trusted vendor network.
Applications
Automotive, marine, off-road, and specialty engines where fast response and fuel economy both matter.

How it earns its place.
Conventional superchargers move a fixed displacement of air. To match a smaller demand, that air must be throttled or dumped — work the engine paid for, thrown away. The Hansen design varies its displacement continuously, so the engine spends fuel only on the air it actually uses.
