adj. term used to describe an internal combustion engine in which air flows into the engine by means of atmospheric pressure only. Compare supercharge.

n: a special compressor used on two-stroke engines to supercharge the engines intake air and scavenge (remove) exhaust gases from the engine cylinders. The blower has tWo corkscrew-shaped (helical) rotors with blades (lobes) that rotate inside a housing. The engine drives the rotors with gears at about twice the engines speed. The rotors rotate in opposite directions at the same speed. As they rotate, the lobes compress air drawn through an air cleaner on top of the housing. The compressed air exits the blower from the bottom or the side of the housing and goes into the engines air intake manifold.

v: to supply a charge of air to the intake of an internal-combustion engine at a pressure higher than that of the surrounding atmosphere.
