Stepless Variable Valve Timing System

View page
US Patent:
20080121198, May 29, 2008
Filed:
Nov 28, 2006
Appl. No.:
11/605121
Inventors:
George Ratz - San Diego CA, US
Rikardo Ratz - San Diego CA, US
International Classification:
F01L 1/047
US Classification:
123 9017
Abstract:
A control system for changing permanently and stepless valve timing in engines with internal combustion.The system is based on the fact that camshaft turns two times slower then the crankshaft.The system contains a double gear that is pivoting around the camshaft gear.The pinion gear is coupled with the camshaft gear.The driver gear is connected to the crankshaft gear through satellite gears, chain or belt. Pivoting the system around the camshaft gear can change valve timing in large limits.There are two different cassettes, the first one (FIG. , FIG. and FIG. ) is for pushrod engines and helps eliminate the inertia of the moving parts. Its movement is controlled by the accelerator pedal.The second cassette (FIG. and FIG. ) is designed for OHC (over head camshaft) engines and it must pivot around the camshafts moved by actuators under the control of the car computer.
