L-Series Air/Fuel Ratio Control
The L-Series 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 L-Series is a microprocessor-based air/fuel ratio control for four-stroke, gaseous-fueled 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. Learn more about the OEM air/fuel ratio control from product spec 03255.
GECOTM
The GECOTM Stoichiometric Model 100 (GECO S100) was designed as an inexpensive, state-of-the-art air/fuel ratio control for natural gas engines in the aftermarket. The GECO S100 is an easy-to-install, low maintenance, and expandable solution for natural gas engines. Woodward is the only manufacturer offering a system for the stationary engine market combining air/fuel ratio with adaptive catalyst control and oxygen sensor health monitoring. The GECO S100's wide range of control authority quickly manages engine speed and load variations. The GECO S100 is also available in a lean burn configuration to further enhance emissions control.
PWM Steppermotor Valve
The PWM Steppermotor Valve (PSV) is a gas trim valve designed to mount directly to a gas mixer (such as the D100 gas mixer). Due to the piston position feedback, the PWM Steppermotor has a high position accuracy which results in excellent Lambda control. The PSV is suitable for naturally aspirated and turbocharged intercooled engines. The PWM Steppermotor Valve covers an engine power range of 70-275 kW (NA and TCI). Learn more about the PWM Steppermotor Valve.
Lambda Control Valve
The Lambda Control Valve and the Double Function Valve are designed to mount directly to a gas mixer (such as the D100 gas mixer). Both valves have a main gas trim function resulting in optimal lambda control. The Double Function Valve has an extra function as idle gas trim valve, which ensures good performance at idling. The Lambda Control Valve and the Double Function Valve cover an engine power range of 70-275 kW (NA and TCI). Learn more about the Lambda Control Valve.
