Variable Valve Operating System for an Internal Combustion Engine

Abstract

A variable valve operating system for an internal combustion engine that has a plurality of electromagnetic actuators for the intake and exhaust valves in a multi-cylinder engine. This engine does not have the conventional lifters, pushrods, rocker arms, cam, timing chain and gear. Computerized software controls and executes the duration of valve opening and closing, lift, timing, and synchronization of the valve action to the crankshaft. This allows a dynamic operation of the engine to effect various selected performance modes. One mode can be selected for the desired driving condition. An engine built comprising this current invention will require fewer parts, be more reliable and less machine work to manufacture as a savings and benefit to all.

1 . A variable valve operating system for an internal combustion engine comprising: 
 (a) a plurality of electromagnetic valve actuators that are installed and attached to each of a plurality of intake and exhaust valves of a multi-cylinder engine.    (b) a computer processor and software/firmware having means to track top dead center of number  1  piston and ignition timing of number  1  cylinder.    (c) said software firmware with means to control the valve's duration of opening and closing, lift, timing, and synchronization with crankshaft.    
   
   
       2 . The software/firmware of  claim 1  wherein said means to control valve's duration of opening and closing is arranged to execute appropriately designed software/firmware to provide one each of multiple modes of performance.  
   
   
       3 . The multiple modes of performance of  claim 2  wherein performance modes can be manually selected one at a time by the operator of the vehicle to instruct said software/firmware to execute the functions necessary for the desired performance mode.  
   
   
       4 . The electromagnetic valve actuators of  claim 1  wherein the design of the tappet covers has the means to cool the actuators by a cooling medium flowing through said tappet covers and passing over said actuators. 
 Whereby we now have said internal combustion engine that can run as a selection of one of several different performance modes and said internal combustion engine will cost substantially less to manufacture because there is a substantial number of parts and amount of machine work that have been e
