The ProAct™ ITB integrated throttle body includes 107 mm, 120 mm, and 135 mm bore sizes, and is designed for use with engines in the 1–2 MW range. These large ITB units are made to couple directly to Woodward’s ProAct™ actuators (an electromagnetic, 75° device), and therefore alleviate the problems associated with linkages on gas engines, such as non-linearity and wear. This direct combination of throttle and actuator results in excellent low-load stability and transient characteristics, and requires no hydraulics, pneumatics, or governor gear train. (product spec 04162) Actuators The L-Series Position Controller provides a building block approach to total engine management. The microprocessor-based bi-directional actuator design easily attaches to fuel pumps, mixers, or throttle bodies. The L-Series Position Controller accepts a position command and drives the 0–60 degree output shaft to the commanded position based on an internal shaft position sensor. The high-efficiency torque motor delivers 0.34 Nxm (0.25 lb-ft) nominally over 60° travel range to operate fuel or air control devices. (product spec 03328) The ProAct™ Digital Plus actuator is intended to be mounted on-engine to control varying functions including (but not limited to): fuel rack positioning, timing control, throttle valve, and wastegate positioning. The actuator is effectively a positioner with an integral driver, which will accept a position command signal from another device in the system such as a speed control. The ProAct Digital Plus actuator includes an integral digital driver capable of controlling the actuator, communicating with the outside control system, and containing on-board software and intelligence to realize monitoring and customizing functions. (product spec 03231) The UG-Actuator offers the advantages of electronic control and load sharing systems while using the convenient, existing UG8-type drives and linkages. The actuator provides the muscle for Woodward analog controls such as the 2301A, as well as Woodward digital controls such as the 2301Dand the 723 Plus. The UGActuator can be used with diesel or natural gas engines, as well as with steam and industrial gas turbines. The UG-Actuator has a self-contained oil sump so a separate oil supply is not required. (product spec 37511) The PGPL Actuator/Driver is an electrohydraulic actuator with a proportional driver interface which can be used with electronic controls providing a 0 to 200 mA position signal. The actuator is designed for use with Woodward 2301A and D series, 700- series, Peak® 150, and 505 digital controls. (product spec 37520) Air-Fuel Ratio Control Units The LCS Air/Fuel Ratio Control provides precise air/fuel ratio control for engines using three-way catalytic converters to reduce exhaust emissions. [A catalyst that simultaneously eliminates hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) is referred to as a “three-way” catalyst.] The LCS is a microprocessor-based air/fuel ratio control for four-stroke, gaseousfueled engines operating with a near-stoichiometric air/fuel ratio. It is designed to work in conjunction with a three-way catalytic converter to efficiently reduce exhaust emissions. By automatically maintaining an optimum air/fuel mixture, emissions compliance is achieved and catalyst life is maximized without operator supervision. An Aftermarket Kit can be applied on engines between 100 kW and 250 kW (134 and 340 hp). The aftermarket kit will accommodate the full range of fuel types and fuel qualities.
