Camshaft valve control layout for IC engine - has camshafts with axes running in parallel and two rows of cylinders

摘要

Camshaft valve control with two rows of cylinders (1,2,3,4) and two camshafts in which the valves (5-10, 15-20) have their axes running parallel to each other. Drag levers (35,36,39,40) are arranged between the first cams (39,30,31,32) and their associated valves (7,8,19,20). Rockers levers (43,44,45,46) are arranged between the second cams (27,28,31,32) and their associated valves (9,10,17,18). The rocker levers have axes (47,48) arranged between consecutive cylinders in the longitudinal direction below the camshafts (25,26). USE/ADVANTAGE - Camshaft valve control layout for IC engine permits a parallel arrangement without increasing the space requirements for the cylinders and the camshafts.
