Let’s address a secondary question first: Will operating my vehicle at a leaner mixture with my Hydrogen Solutions Center system, cause damage to my valves?
With a Hydrogen Solutions Center system seeking to run on the leanest air/fuel mixture that has acceptable torque and power, in pursuit of the best possible gas mileage, we have had repeated questions from misinformed customers concerning whether they would burn their valves by running the extra lean mixture. Our answer to make sure or this misinformation comes from the aviation field. An aviator I know told us that piston engine aircraft take off and climb at maximum power, and cruise at a leaner mixture, watching the EGT gauge to insure a safe temperature. Of course we all assume that safe temperature means a temperature that doesn’t burn the valves. This information gets us to assume that an electronic fuel injected engine runs at the rich mixture that is cool enough to protect the valves from burning. Most also assume that if we lean out the mixture we will be in danger of burning the valves. A ‘too hot’ exhaust gas temperature also would indicate a too hot combustion temperature t
