Piston engine e.g. sport and/or racing engine, has intake system having intake manifolds and integrated electro-mechanical pressure wave generator

摘要

The piston engine has intake system (1) having an intake manifolds (S1,S2) and an integrated electro-mechanical pressure wave generator (2). The pressure wave generator has a frame (3) with clamped rubber supported metal membrane (4) which is enclosed by voice coil (6) which is in turn surrounded by a magnet (7).
