LEED-Certified Structure Welded with Miller Electronic Fuel Injection (EFI) Welder Generator

While construction equipment is just one small portion of the LEED certification equation, Apex Steel ran one of the first Trailblazer® 302s with electronic fuel injection (EFI) and realized a 20-percent reduction in fuel use while also reducing harmful HC, CO and NOx emissions.

What I want to know about is how it handles crap gas, service guys that don't run 8 hours a day, or even everyday at all. If it sits on the truck with out running with the worthless modern gasoline turning to corn-varnish will it start/idle/run smooth? ie will fuel injection pressure help push the fuel thru a deposit? This is the question that has me considering a deisel or LPG machine next. But I was hoping for economy that efi might be a cheaper solution to bureaucrat-gas.

Good question. One of the strengths of the EFI system is handling poor quality and aging gas. Gasoline varnishes when exposed to atmosphere for extended periods of time. That causes problems in carburators that have fuel sitting in them and also have the fuel exposed to the atmosphere. In the EFI system, there is no fuel bowl, and the fuel is not exposed to atmosphere which greatly reduces it degrading and varnishing.

In addition, the fuel in the EFI system is under pressure and pressure also deters varnishing.

So, while EFI is greatly beneficial to construction and fabrication users who put a lot of hours on the machine because of the fuel savings, it is very beneficial to the user who does let the machine sit for periods of time in between uses because it eliminates carburetor problems caused by fuel varnishing.

So the dude is worried about emissions from that little engine? Carbon print this and carbon print that, just a bunch of catchphrases to sound more "green." Not sure what the big deal is, plants use CO2 to make O2, at least that is what I was told in school. So what's the problem? And my fuel injected Honda motorcycle clogs up way faster than my 1980 carbureted BMW R100T motorcycle. So all of you theorizing about fuel injection being better for overcoming degrading fuel problems are wrong.
