NOVELTY - The system (100) has an actuator (110) for generating linear motion. A transform mechanism (201) is coupled to the actuator, and transforms the linear motion of the actuator into rotational motion for actuating a throttle valve. The actuator includes an actuator rod (112) coupled to the mechanism. The mechanism includes a turning device (230) to be coupled to the valve. The mechanism includes a control rod (120) with first end (122) and second end (124), where the first end is coupled to the actuator rod of the actuator and the second end is coupled to the turning device.    USE - Control system for controlling operation of an on/off throttle valve e.g. wastegate valve and blow-off valve, in a throttle valve assembly, of an internal combustion engine (all claimed) e.g. V-type 8-cylinder dual fuel main/auxiliary internal combustion engine such as turbine engine, gas engine, diesel engine, natural gas engine, propane engine and dual fuel engine, of a vehicle, in engine powered application. Uses include but are not limited to an on-highway lorry, off-highway lorry, earth moving machine, earth moving equipment and ship e.g. cruiser liner ship, cargo ship, container ship and tanker ship, in locomotive applications, stationary equipment applications, generator applications, industrial applications, aerospace applications and pump applications.    ADVANTAGE - The actuator controls operation of the throttle valve so as to reduce heat impact on the actuator, so that the system ensures proper operation of the throttle valve when the actuator can be spaced apart from the throttle valve to be employed in an exhaust gas system of an internal combustion engine. The system is provided with an outlet of the turbine that can be fluidly connected to an exhaust gas stub so as to release exhaust gas into an exhaust treatment system or directly to the environment through an exhaust pipe.    DETAILED DESCRIPTION - The actuator is an electric actuator. The turning device is a pulley device. INDEPENDENT CLAIMS are also included for the following:    (1) a throttle valve assembly    (2) an internal combustion engine    (3) a method for controlling operation of a throttle valve of an internal combustion engine.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a throttle valve with a control system to control operation of the throttle valve.
