ok that sure makes sense. Cooling of parts, harmonics, and lubrication. Everyone knows that you break in your car by driving first several hundred miles at varying speeds and rpms, but I've never had a clear understanding of why. Sometimes its always very good to return to understanding the basics.
So it seems that an industrial engine could be used easily in an automotive situation, but an automotive engine might not be stout enough or lubricated properly for an industrial scenario. Bigger rods and cams is simple enough, but how is the lubrication problem solved?
Ok, so next question. Do you know how power is calculated? I dont know how power is defined, either in hp or torque presumably, but for instance on a multifuel engine the strength of the fuel as determined by BTU's presumably will vary. I seem to remember (but I could be wrong on the numbers) that automotive diesel is like 115,000 btu's/gal and standard 87 gasoline is 85,000 btus/gal, and propane is like 55,000 btu's/gal or something. So presumably with the same engine, the different fuels will result in different power outputs, however thats measured. Do you know how you would calculate this?
And by the way, I appreciate your input as well as everyones here. I find it very interesting learning from this group of knowledgeable people. Thanks.
