( Deere's Application Guideline 18 has more to say about use of aviation fuels, including this: PowerTech PSX, PVX, PWX Engines \(4.5 L / 6.8 L / 9.0 L / 13.5 L\) \(Engines with John Deere supplied Diesel Oxidation Catalyst\) Aviation Fuels All Not allowed. Aviation Fuel has sulfur content levels greater than 0.002% \(20 ppm\) and are not allowed for use with John Deere engines with Diesel Oxidation Catalyst. This includes fuels such as;...

Lightened Crank Question
Published (2009-11-05 20:00:00)
I know of all the points you made regarding the engine characteristics. I guess we are trying to have our cake and eat it too. I want the power/torque of the 750 engine but I want it to rev and handle like the lighter 600 engine.

Lightened Crank Question
Published (2009-11-05 19:41:00)
( Kev A bigger engine is normally slightly less responsive than a smaller engine as the parts are normally heavier caising higher inertia. The further the weight is removed from the axis of a rotating part the greater the reduction in inertia and gyro effect. A heavier bike and stronger gyro will both contribute to slower transition. A heavier crank contributes to both. The bigger motor, even though less responsive on a free rev will have more...

I have to admit that sabotage did occur to me too. It does happen.

If the jacket water heaters are convection type, then yes, they can degrade the corrosion protection. If you pull a heating element out and see a white to tan deposit, and loose debris in the bottom of the tank, then your tank heaters are affecting your coolants corrosion protection. KIM Hotstart sells smaller jacket water heaters with small circulation pumps, actually work better than the convection...

CNG DI injector

hajiali- I would be pessimistic you could build one in a reasonable amount of time for a reasonable amount of money. If you want this for research purposes, get in touch with Westport Innovations and explain what injector you want. Make it clear that this is for research...

Like anything, there is a large gap between what you can get away with for XXX operating hours, and what the system in question has been validated to work with for its specifed life.

Adding 2 stroke oil to diesel fuel
Published (2009-10-29 04:47:00)
OK guys, hold back, snake oil it is then. I knew I could rely on you lot to put me straight ! To put a slightly different twist on the discussion, whats the best way of adding some sulphur back into ULSD for the old timer motors that need this for lubrication ? Once you've got the sulphur levels back up (is there a limit ?) do you need to consider what spec of sump oil you use to cope with the new sulphur ? Or is there...

The further from the center the mass is removed, the greater the reduction in inertia. See the simplified treatment here: http:/ /www.engin eeringtool box.com/mo ment-inert ia-torque- d_913.html From a performance standpoint, you want to decrease inertia. Since the overall mass you are saving in a linear sense is not significant. Although I imagine the manufacturer sized the ...

First of all let me apologize ahead of time for my not being a engineer and dropping into this forum to start a thread. I've considered discussing this concept in other forums but had the impression that the members weren't quite eager to take up the topic. I'm not an engineer - I'm a small business owner - but I'm considering becoming a mechanical engineering student. First a quick outline ...

Up to 01 these units had indeed cam wear problems, it was to do with the case hardening process and the way it had been carried out. I have come across one only after 01 to have wear issues but I have a feeling after doing a bit of research that the correct oil had not been used or service intervals abused. Although this is not a pumpe duse(PD, unit injector) engine I do believe that using the ...

and forgot to add, is there any possibility that using 2 stroke oil (1:200 ratio) will cause any damage ? The only thing I've see is not to use it with DPF set-ups.
