what engines are capable to run 100% on hho, h2, hydrogen gas for vehicles?

David Schw

Is there ideal engines for the conversion? I want to construct a van that holds enough hydrogen to operate 200 miles power day ++ and cover it with solar panels & a bracket to hold a1,500 watt windmill. Ideally,I would use an AC outlet to produce the hydrogen but with added options to make its own too. This is the ultimate bug out vehicle. I will probably wonder off into the wilderness forever once its complete.

Sounds like an interesting project. There are some car companies that make hydrogen internal combustion engines/cars but they are hugely expensive and conversions from gas to hydrogen has some problems. A propane engine design might be suitable for adaptation to hydrogen. The fuel/air mixture is much different for hydrogen requiring special carbs and engine timing changes and hydrogen embrittlement of engine parts or exhaust can lower engine life and other parts.
Storing hydrogen is another issue as it requires a large volume of gas under very high pressures to have a suitable range you're looking for.....special tanks, lines, valves, refueling, etc..

There are some new methods coming out to make on-demand low pressure hydrogen gas using chemical processes like sodium silicides or cobalt catalysts which could alleviate some of the problems with onboard storage/use. You can also make hydrogen from urine which has twice the hydrogen molecules as water and splits apart in electrolysis at lower voltages..

Kohler SV590 mower engine will not start.?

Lee

Have a troy-bilt rider with Kohler SV590S (SV590-0017, see below) that has been stored and unused last season (2012), i.e. stored fall 2011, with stabilizer treated gas. Now won't go. new gas, Fuel flow from tank to carb OK (through fuel filter), fires if carb sprayed with carb cleaner. Solenoid works (don't know if it was stuck at first before I pushed on it a couple of times).

Got the bowl off, ruined the gasket. Local repair shop pointed out that a disk (about 3/8 inch) was missing, probably due to freezing with water in gas. He had kit with gasket, disk and other pieces.

Cleaned carb with carb cleaner, which blew through all the various ports (3x so far). Reassembled, still dies when (jump) starting, but runs for a few seconds with some carb cleaner down the throat. Can hear solenoid click, bowl now has some gas in it when removed.

Each time I made sure that the various interlocks were OK - seat down or bypassed, brake on, PTO (blade) off, and jump started since battery is only good for a few tries if charged overnight.

Note there is no evidence of a fuel pump as shown in the manual as the gas line goes from fuel tank to filter to carburetor.

Now what? Any suggestions for troubleshooting & fix ups so that my son doesn't have to use the push mower again? Can't afford repair shop diagnostics - unemployed

(will probably have to replace battery again if this thing starts)


Kohler Courage 19 Engine SV590S (electric start) Spec no SV590-0017 (MTD) SN 3605950363 (found manuals online including service manual 20 690 01 Rev. G)
Troy-Bilt Model 6605 SN 1C026H20244 Manufactured 3/2006 13AX60TG766 (found manuals online)

BTW: Also when moving carburetor assembly noticed an extra spring on the ground - about 1 5/8 inches long with squared hook at one end and rounded "eye" at other, narrower coil at hook end to wider coil at "eye" end. Looks brand new and mower is 2006 so suspect spring is from something else, like a new bike that was being worked on a few days earlier. Also not in found in any of the parts diagrams related to the fuel & throttle assemblies. Hopefully it is not from the mower. Looked at Troy-Bilt mowers with Kohler engine in store with similar throttle/choke assembly and do not see any evdience of this spring.

I have the following online manuals obtained online over the last few days. Note that file names listed below have been prefixed with descriptive names

Answer
I think that you still have something in the carburetor that needs to come out. Sometimes it is difficult to get the things clean. I use a chem dip type cleaner that I got from the auto parts store specifically for carburetors. Comes in a gallon can for around $20.00 but last for years and is good for a lot of parts. You take the carb apart and soak for an hour or so, rinse it with water and blow it dry with compressed air. Works first time every time, except once on a outboard motor, but that is a different story. It is possible to get them cleaned out with spray carb cleaner once they are off and taken apart but it doesn't work as well as the soaking cleaner. When taking things apart that are somewhat complicated, a digital picture or two can save your bacon in the home stretch. Anyway, what you describe sounds to me like a dirty carburetor.
