IMPROVEMENTS IN OR RELATING TO THE VALVE TIMING MECHANISMS OF INTERNAL COMBUSTION ENGINES |
摘要 |
<p>An internal combustion engine having at least one cylinder with inlet and exhaust valves operated via rocker arms by respective cams carried by a single camshaft. The camshaft is connected to its drive by an eccentric linkage, the eccentricity of which is varied by a device responsive to engine speed, and is least at high speed. As engine speed falls, increasing eccentricity results in a relative advance of inlet valve closing time and relative retardation of exhaust and inlet valve opening times but little change in the timing of exhaust valve closure. The lift of the valves may be varied also if the rocker arm axes are movably mounted.</p> |
