Are you tired of doing things the efficient way when using your lawn equipment? Look no farther. Here are some engine hacks where regular internal combustion engines have been modified to work on steam or compressed air. Surprisingly, all it takes to do this is to remove the carburetor and replace it with a steam line and to modify the valve timing.
First up is a lawn mower that runs on steam posted by [dquad]. This one is pretty great because it just looks so wrong. In [dquad’s] own words: “I am surprised by the fact that nothing at all failed during this test – other than a wheel catching fire!”
Check out some other examples of engines converted to run on air or steam after the break…
Here is video posted by [greenpowerscience] where a two-stroke engine has been converted to run on air and which also has a solenoid valve to control the air.
Finally, if you are wondering how these folks are converting their engines, take a look the second video on this page where the valve modifications are shown.
