ABSTRACT:
A family of embodiments of mechanical, electromechanical and electronic for the control of intake and exhaust cylinder valves applicable to both spark and compression ignition engines. Electronic control or programming of valves in respect to their opening and closing times is effected in accordance with predetermined relationships based on data such as air density, engine temperature, engine speed, vehicle speed, fuel octane, automatic transmission data and operator control commands and operating mode selections is provided. The operator control commands include acceleration and deceleration; and the operating mode selections include "computer starting" (without cranking as by a starter mechanism); and constant speed, constant torque, engine reversal, low nitrogen oxide emission, high performance, optimum fuel economy and service modes.
