Air-fuel mixture preparing device for gasoline or diesel engine, has piston vibrating in main inlet line, where acoustic wave created in line is amplified due to mixing of air and fuel mixture caused by fuel and air column oscillation

摘要

The device has a piston (1) vibrating in a main inlet line (2) to assure forced oscillation of air, and driven by cams (3) that are driven by cam shafts (11). The camshaft is driven by a belt drive system (10). Fuel is injected before opening an inlet valve. Oscillation of fuel and air column permits mixing of air and fuel mixture, so that acoustic wave generated in the main inlet line is amplified.
