IGNITION AND ION SENSING PRODUCT OVERVIEW SmartFire Instrumentation Ignition The SmartFire ignition controller is the state of the art in combustion electronics. SmartFire and its combustion analysis software, WinFire, can be used to gather combustion data crucial for engine development and tuning with no modifications to the combustion chamber. SmartFire is the first commercially available ignition and engine diagnostic system to fully utilize ionization feedback. SmartFlame Module The SmartFlame module was developed to meet the need of researchers experimenting with ion currents. It provides a simple and convenient method of creating an ion bias voltage. Since the module is totally isolated it is easy to hook up and install. This module is used in conjunction with standard off the shelf NI hardware. It allows for real time acquisition and processing of ion signals. This platform can communicate the data either digitally over a network or analog via any of the many off the shelf modules. The NI systems that hold these modules range in size from 4-module portable systems to large rack mount systems capable of holding hundreds of systems. PAGE 7

SmartFire Instrumentation Ignition The SmartFire Instrumentation Ignition system provides the most user-friendly combustion feedback tool available. SmartFire provides individual cylinder feedback in a real time format and is designed to aid dynamometer operators eager to maximize their engine performance. The SmartFire system has applications on gasoline, natural gas, diesel and HCCI engines. On gasoline and natural gas engines the SmartFire system uses high-speed signal processing of the ion signal to detect ALL misfires. When misfires occur SmartFire uses closed loop re-strike to re-ignite the cylinder to prevent combustible mixtures from escaping the combustion chamber. SmartFire detects every occurrence of pre-ignition in the cylinder this feature is not available with conventional acoustic systems. SmartFire makes it possible to calibrate engines using misfire detection and prevention through the tip of the sparkplug without drilling holes. SmartFire is capable of using ion signals to detect knock with greater sensitivity than traditional acoustic transducers. SmartFire enables dynamometer operators to take full advantage of the system s unique ability to do knock calibrations where invasive cylinder pressure sensors are normally required. The system is designed to help maximize engine performance. Through in-cylinder start of combustion flagging on diesel engines, closed loop injection timing control is possible with SmartFire. The system is also able to improve cold startability of diesel engines compared to traditional glow plugs. The SmartFire system is able to provide feedback to control fuel injection and ignition timing on an individual cylinder basis. SmartFire uses ionization feedback to allow the engine builder to dial in the maximum horsepower for each individual cylinder. The SmartFire system includes a PC interface, which allows the operator to view the ionization waveforms of each cylinder in real time. The system can fire and monitor up to 12 cylinders. Knock and misfire displayed on PC software Rapid engine calibration Ion sensing through the tip of the sparkplugs NO DRILLING HOLES Knock detection Misfire Detection for OBD II Misfire Prevention Quicker integration Can be installed and running in as little as 3 hours Runs on Windows 95/98/NT/XP PAGE 8

SmartFire Instrumentation Ignition BENEFITS Data Acquisition Ionization can be logged to either the display PC or to the dynamometers high-speed data acquisition system. SmartFire performs knock and misfire detection in a real time format directly through the spark plug, with no extra holes to drill. SmartFire can analyze ionization from any type of fuel. Compatible with any engine the system provides an excellent return on investment. SmartFire s real time display is a useful tool for realtime engine development and diagnostics. Capable of data logging on Dyno and during in car transient testing. SmartFire eliminates drilling of any extra holes in engine to get good combustion information.

THROTTLE BODY PRODUCT OVERVIEW L Series ITB Integrated Throttle Body The L Series ITB is a member of Woodward s Integrated Throttle Body family. Several throttle body size configurations (between 25 and 50 mm) are integrated with speed control or actuator options for use on gaseous fueled industrial engines between 5 and 100 kw (7 and 134 hp). Applications include automotive, power generation, refrigeration units, pumps, irrigation, mobile industrial, and gas trim valves. The L Series ITB integrated throttle body and speed control or actuator provides a building block approach to total engine management. This modular design consists of a die-cast aluminum throttle body plus a fully programmable integrated digital speed control and bi-directional actuator. Flo-Tech ITB Integrated Throttle Body/Actuator The Flo-Tech ITB integrated throttle body and actuator is designed for direct replacement of manual throttle bodies, and is designed with flow shaping to assist in engine idle stability. The throttle body will provide equivalent maximum flow rates of standard butterfly throttle bodies of the same diameter. The system contains a return spring to fully comply with DOT 571.124 specifications. Determination of the proper size requires a knowledge of the absolute pressure drops across the valve, the expected temperature of the gaseous media flowing, and the density of the gas. Cv (volume coefficients) are provided to determine the flow vs. angle. For initial testing, a valve body diameter similar to the one typically used on the application can be used. The Flo-Tech integrated actuator/throttle body requires no actuator or linkage. ProAct ITB Integrated Throttle Body 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-degree 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. PAGE 25

Several throttle body size configurations (between 25 and 50 mm) are integrated with speed control or actuator options for use on gaseous fueled industrial engines between 5 and 100 kw (7 and 134 hp). Applications include power generation, refrigeration units, pumps, irrigation, mobile industrial, and gas trim valves. The integrated throttle body incorporates the proven Woodward L Series speed control or L Series actuator, which operates the throttle plate. The L Series ITB Speed Control can be programmed via the RS-232 port of a personal computer to a variety of configurations, as follows: Isochronous speed control Droop Auxiliary input Dual dynamics Adjustable ramp time Self-tuning gain The L Series Actuator comes in two basic configurations with or without on-board final drivers. The onboard driver version accepts a 7 32 Vdc, 150 3100 Hz PWM position command signal. The version without drivers brings the actuator coil (4 Ω @ 25 C, 14 mh @ 500 Hz) leads directly out to the Deutsch connector. The L Series Actuator also has an optional, integral 0 5 Vdc throttle position feedback signal. DESCRIPTION The L Series ITB integrated throttle body and speed control or actuator provides a building block approach to total engine management. This modular design consists of a die-cast aluminum throttle body plus a fully programmable integrated digital speed control and bi-directional actuator. The throttle body incorporates a corrosionprotected, plated steel shaft, plate, and a sealed ball-bearing design for durability and long life. An internal throttle return spring is standard to close the throttle in the event of power failure. The modular design of the L Series ITB system reduces total engine assembly cost, eliminates external linkages, lowers inventory and part number proliferation. The programmable controller offers security to your configuration. The L Series ITB speed control is compatible with Woodward s venturi-style mixer and other brands of gas mixers using suitable adapters (see L Series product specification 03225 for speed control details and operating parameters).

Flo-Tech ITB Integrated Throttle Body and Actuator 04140B APPLICATIONS The Flo-Tech ITB integrated throttle body and actuator is designed with flow shaping to assist in engine idle stability. The throttle body will provide equivalent maximum flow rates of standard butterfly throttle bodies of the same diameter. The system contains a return spring to fully comply with DOT 571.124 specifications. Determination of the proper size requires a knowledge of the absolute pressure drops across the valve, the expected temperature of the gaseous media flowing, and the density of the gas. Cv (volume coefficients) are provided to determine the flow vs. angle. For initial testing a valve body diameter similar to the one typically used on the application can be used. The Flo-Tech ITB is designed for direct replacement of manual throttle bodies. It requires no actuator or linkage. DESCRIPTION The Flo-Tech family of electrically actuated throttles/valves controls flow. The flow is a function of throttle position and pressure drop. The throttle position is proportional to the position command signal. The Flo-Tech ITB can be made with 33, 48, 60, 68, and 75 mm bore sizes for various applications. Command input options come in PWM, 0 5 Vdc, 4 20 ma, and 0 200 ma. Position feedback output signal will vary from 0.5 ± 0.1 volts to 4.5 ± 0.1 volts nominal at the min and max actuator position respectively. The PWM command input version will return to minimum actuator position with a command of greater than 95% duty cycle. The Flo-Tech actuator requires a power supply of 9 32 Vdc. The supply must be capable of supplying a sustained 25 watts at steady-state and 50 watts for transient state conditions for at least 0.25 second. No linkage or couplings Cost-effective and highly efficient Extremely low maintenance product Small size for easy installation Conveniently integrated electronics Includes returnspring to fully comply with DOT 571.124 specs Versatile 12 or 24 Vdc operation PAGE 28

Flo-Tech ITB Integrated Throttle Body and Actuator 04140B INSTALLATION The Flo-Tech ITB integrated throttle body and actuator may be mounted in any position. Both mounting flanges on the throttle body have four 10 mm through-holes in a square, 74 mm pattern. The base of the unit has an optional bolt pattern that can be used for mounting support. It uses 4 M8x0.125 bolts in an 88.9 mm square pattern. The connector to the Flo-Tech actuator is a Packard Electric male connector. The mating connector is a Packard female connector (Woodward p/n 8923-461) with seals and pins. Different connectors are available but not standard. Please contact the factory if you would like to use a different connector. Cv for Standard Flo-Tech Units DETERMINING PROPER VALVE SIZE Proper valve size can be determined by using the following equation: Cv = Q *.00978 * (G * T / ((P1 P2) * K)) ^ 0.5 Where: Q = Flow (PPH) G = Specific gravity of fluid ( = 1.0 for air) T = Absolute temperature (460 + F) P1 = Inlet pressure (psia) P2 = Discharge pressure (psia) K = P2 if P1 P2 is less than 10% of P1 = P1 if P1 P2 is 25% or more of P1 = (P1+P2)/2 if P1 P2 is in between 10 & 25% P2 must be Greater than.53 * P1 (or flow becomes choked). Cv (flow coefficient) should be calculated for the minimum and maximum flows expected (at 50 ) on the application. Cv (Flow Coefficient) Angle 33mm 48mm 60mm 68mm 75mm 0 0.689 1.36 1.81 2.44 1.41 5 0.787 1.81 2.57 3.04 3.37 10 1.30 3.34 4.65 4.83 2.71 15 2.70 6.64 9.39 10.4 8.28 20 4.63 10.8 15.9 18.3 16.9 25 6.86 16.0 24.0 28.1 28.3 30 9.58 21.8 33.1 39.7 41.8 35 12.7 28.5 43.7 53.4 57.8 40 16.3 36.2 55.9 70.0 76.2 45 20.4 45.0 70.4 88.0 97.3 50 24.9 54.8 86.8 109 120 55 30.1 65.9 105 133 147 60 33.8 75.6 125 157 174 65 35.9 81.6 138 179 200 70 36.1 82.9 151 197 220 COMMAND VS. POSITION FEEDBACK/THROTTLE POSITION The actuator is designed to provide 0.5 volts output at zero position, and 4.5 volts at full position. Feedback signals of 0 or 5 Vdc indicate faults. The PWM input signal greater than 95% causes the output to go to zero position. Thus, if the PWM fails to 5 Vdc, the unit fails in a safe direction. Temperature drift from 25 C to 105 C or from 25 C to 40 C causes the internal sensor to shift calibration. The effect of this is that the output position does not start to move until 0.8 Vdc and gets to the full position at 4.2 Vdc at 40 and 105 C. The output position signal will still track the command signal. This means that although the OEM cannot use this signal for true position, the OEM can still use this signal to verify that the Flo-Tech unit is responding to the command signal. PAGE 29

ProAct ITB Integrated Actuator and Throttle Body for Large Bores (105, 120, 135 mm) 03305B No linkage or couplings Cost effective and highly efficient Low maintenance Requires no hydraulics, pneumatics, or governor gear train Long lasting, easy to install throttle option APPLICATIONS The ProAct ITB integrated actuator and throttle body is designed to throttle air or air/fuel for gaseous engines. This system is designed for direct replacement of traditional throttle valves, and requires no linkage between valve and actuator. The three sizes are designed to cover a wide range of engines and should be selected using the sizing procedure described inside this specification. DESCRIPTION The PoAct Integrated Throttle Bodies (ProAct ITBs) are butterfly valves electrically-actuated by ProAct Analog and ProAct Digital Plus actuators to control flow output. With bore sizes of 105 mm, 120 mm, and 135 mm, these ProAct ITBs are designed for use with engines in the 1 2 MW range. The ProAct actuators are electro-magnetic, 75 degree-of-travel devices, and therefore alleviate the problems associated with linkages on gas engines (such as setup, non-linearity, and wear). This direct combination of throttle and actuator results in excellent stability and transient characteristics, and requires no hydraulics, pneumatics, or governor gear train. Therefore, you end up with an efficient, long lasting, and easily-installed throttle option. PAGE 32

ProAct ITB Integrated Actuator and Throttle Body for Large Bores (105, 120, 135 mm) 03305B DETERMINING THE PROPER VALVE SIZE The proper size valve can be determined using the equation below. The required Cv (flow coefficient) should be calculated for both the minimum and maximum flows expected on the application. This design allows for a nominal travel of 75 degrees of rotation. Using the graph and table below, select the closest valve that has a Cv equal to or greater than the calculated maximum flow value at approximately 80% opening (60 degrees) to ensure reasonable flow margin. Also, check that the particular valve s minimum Cv listed below is less than the minimum calculated Cv for good low idle performance. For further assistance, consult the Woodward engineering department. Cv vs Angle for ProAct ITBs Cv := Q. 0.00976. P1.Sg (T + 460). P1.
