Gas Engine Controls

The Woodward 2301A Load Sharing and Speed Controls are designed for use in electric generator systems where multi-unit load sharing is desired. 2301A controls may be used with diesel, gas or gasoline engines, or steam or gas turbines. Controls are available for applications requiring droop and/or isochronous speed control; in forward- or reverse-acting models; for single or tandem actuator installations; with accelerating or decelerating ramps; and in several speed ranges. Automatic, adjustable start fuel limiting regulates the maximum fuel setting while the engine is starting.

Woodward?s 2301E provides load sharing and speed control of generators being driven by diesel or gaseous engines. Using an external computer (PC) and built-in configuration software, application variations may be programmed to accommodate engine speed range, gear teeth, and select forward or reverse acting The 2301E controller is backward compatible with existing 2301D products using the same footprint and mounting configuration with enhanced features.

The Woodward 723PLUS Compressor Performance Control controls the speed, air/fuel ratio, and ignition timing of reciprocating engines in variable speed/load applications. The control includes inputs for two speed sensors for monitoring engine and turbocharger speed, a notch filter to attenuate the effect of flexible coupling torsionals, a remote speed setting input, and inputs for air manifold pressure, fuel gas header pressure, and air manifold temperature.

The Woodward 733 Digital Control manages and controls reciprocating engines (gas, diesel, dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. It has been designed to enable to be mounted directly on the engine or inside control cabinets. The 733 is available as a stand-alone speed control and is the main control unit within an engine management system. Designed for network connectivity, it may be programmed to perform all engine functions: speed, air and fuel control, monitoring, alarms, engine protection and sequencing.

The Woodward E3 Rich-Burn Trim control system is designed for the most popular engines used in gas compression and many power generation or irrigation pump applications. The system analyzes and controls all of the functions of an engine and catalyst, optimizing the amount of time the engine is in compliance.

The Woodward E3 Lean-Burn Trim control system is designed to control lean-burn industrial gas engines used in many power generation, pumping, and other stationary applications ranging from 300 kW to 2,000 kW (400-2,700hp). The highly accurate, closed-loop control system helps customers meet regulated emissions levels, while maintaining engine performance over a very large range of fuel qualities.

The Woodward FireFly™ Control detects the occurrence of knock in gas engines and adjusts the ignition timing to compensate. This provides protection from the harmful effects of knock and thereby increases efficiency. The FireFly uses knock sensors placed on the engine block. These sensors pick up vibration signals and the FireFly detects the specific vibrations associated with determining the knock condition. The FireFly ensures that only knock related vibration signals are acted upon, ignoring all usual vibration signals produced by a gas engine.

The Woodward Gas Engine I/O-Node (GEION) in combination with 723 DCS can be used for lean-burn gas engines running in both “closed or open loop” air fuel ratio control and for stoichiometric gas engines, naturally aspirated or turbocharged, in the power range of 20 to 2000 kW. In case of a V-engine, air fuel ratio control per bank is possible using two gas engine I/O-nodes and a 723 DCS, one for each bank. The gas engine I/O-node is specially designed to do the air fuel ratio control on carbureted turbocharged or non-turbocharged gas engines.

The Woodward In-Pulse™ II Fuel Injection Control manages and controls electronically fuel injected (EFI) reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, industrial engine, and process markets. It also managesthe core fuel system and injection events for many EFI fuel systems, including electronic unit injectors and pumps (EUI/EUP), common rail systems (C-R), SOGAV™ Solenoid Operated Gas Admission Valves, micro pilot injection systems, and electronic rail valves (ERV). The In-Pulse II can mount directly on the engine nearby control cabinets.
