Dual Fuel Injector

1. Throttle body with integrated electronic governing maintains precise engine speed control
   
   
   • Operates without the need for a throttle position sensor
     
     
   • System does not require external throttle linkage
     
     
   • Governor can maintain 3 set speeds plus idle speed (4 total operating speeds)
     
     
   • Unit can also be operated utilizing drive-by wire technology
     
     
   • The Electronic Control Unit (ECU) mounts directly to the fuel system throttle body and can control ignition timing and governing on DIS equipped engines
     
     
   • Engine can be easily de-rated (power) per application requirements or customers specifications
     
     
   • Customized PID settings allow superior governor control for each individual customer application
     
     
   • Tamper proof controls ensure continued optimum performance for life of system
     
     
2. Delivers only the amount of fuel the engine requires to operate efficiently under different load conditions
   
   
   • Better engine exhaust emission control (Enables engine manufacturers to meet emission requirements.)
     
     
   • Automatically compensates for altitude changes
     
     
   • Enhanced fuel economy
     
     
   • Closed loop system with O2 sensor for optimum 3-way catalysts emission performance
     
   
   
3. Enhanced engine performance over carburetors
   
   
   • Superior cold weather starting (Eliminates need for automatic and/or manual choke.)
     
     
   • Eliminates dieseling of engine on shutdown
     
     
   • Superior hot start performance
     
   
   
4. Compact size and design for easier application and installation of package
   
   
   • Designed to fit within current carburetor size envelope for easier installation
     
     
   • All electronic components are environmentally sealed and protected
     
     
   • Maximized use of automotive components and sensors for cost control and assurance of quality
     
     
   • Provision of EGR control if required by customer application
     
     
   • Diagnostics can be accomplished using a common 12 volt test light for field service
     
     
   • Capability for dashboard diagnostics can be added with software revisions
     
     
   • Easy calibration for different engine sizes and applications
     
     
   • Single throttle body design can accommodate 1 to 3 liter engines - gasoline or liquid propane
     
     
   • Engine manufacturer, distributor, or application builder can customize performance parameters
     
   
   
5. Can be used for various fuels: gasoline and liquid propane
   
   
   • Can be used for dual fuel applications
     
     
   • In-line fuel pump supplied as part of system provides easy installation and application flexibility
     
   
   
6. Dual Fuel system has capability of switching fuels on-the-fly while engine is running under load
