New water injection system
Previous Image | Next Image
Description: I've made an air intake pipe that sweeps back to connect to a 44mm carburetor to inject water. I'll need to cut off about half this pipe and complete it with a rubber hose.

Sorry. This has been covered extensively on other threads, so I probably need to explain! :)

I have built a biodiesel RE using a 2000 military frame. I have added a water injection system to improve efficiency (by as much as 20 percent). Essentially, the diesel uses a fuel injector, no carburetion. By adding a carburetor to the air intake of the diesel, and using the carburetor to meter water into the air intake, I add water to the system as a supplementary fuel. The water is converted by the diesel fuel combustion into steam with a 1700:1 expansion ratio. More than a certain amount of water decreases performance; but up to a certain point, you get greater fuel efficiency.
