Step 13Air Intake With Butterfly Valve
The syngas and air are both going into the Honda engine via the original air intake. That means the Honda engine can no longer control its own fuel/air mix. We built a new air intake with a butterfly valve so that we can control the fuel to air mix ratio.
The fuel to air mix needs adjustment while the car is driving, so we added a servo control which can be operated from the driver seat.
- The new airtake starts with a length of 2" diameter PVC pipe.
- The butterfly valve is a fender washer that matched the ID of the pipe.
- The fender washer is screwed to a 1/4" diameter aluminum rod
- The aluminum rod goes through 2 holes drilled across the pipe
- The servo turns the rod to open and close the valve.
