small engines

[Bruce Hopf]

is there sombody who can tell me what horse power with a gas engine rateing would be compaired to a 6 horse powered diesle engine rateing. thanks

6 HP is 6HP. If you're talking torque, now that's another story.

Thanks for your reply. I realize 6hp is 6hp. My mistake. I should have ased about torq equivelentsy between the 2 types of engines. What hp of gas engine has torque iquivilent to a 6hp diesle engine? thanks.

Depends on the design of the gas engine. Stroke length, etc all have to do with torque.
Comparing torque figures is the best way.

RPMs being equal I would say diesel would usually have more bottem end torque. Matching up I figure 8 hp for a gas engine would probably be equal or close to 6 hp diesel torquewise but, if you need exact I would go with manufacturers specs.

Torque times RPM divided by 63025 equals horsepower (T_x_RPM_)
(63025) = HP
Horsepower times 63025 equals torque times RPM

6 Hp is 6 Hp, but the diesel may have more torque
at a lower RPM

Thanks for the replies.
Thinking of swapping an 8 hp gas to a 6 hp deisel, on my 8 hp x 26" snowthrower, or my Troy Built Tiller. Thanks

RPM's are one of the differences. Most small gas engines develop ratted HP at maybe 3600 RPM diesels are much slower for the most part maybe 2500 rpm for their rated HP.

then the torque on a gasser will vary depending on stroke length and such....lots of variables.

Bruce Hopf: I had a good friend here in my home town, whose name was Hopf! He pronounced it as Hoff, silent P. I live near Pittsburgh, Pa. Haven't seen that name much of anywhere than this area.
Just thought you'd like that info.

My grandfather imigrated to Canada, some time 1920, 1921, from Germany, some where around the Black Forest area. Ive noticed the Hopf name on here a couple other times. Chated with one guy, I think from MN. with the Hopf nane on anouther forum. He also told me when I think, his Great Great Grandfather came to the US through Ellis Island, and the inspector spelled the Hopf name Hoff, and he didn't wan't to make the inspector mad, so he left it alone. I know Hopf is an oncomon name, compaired to Hoff.

Bruce You nay need to account for rpm diferernces between deisel & gas with different pulleys. Probably wouldn't be too bad on a tiller but a snow blower usually needs max rpm to make it work right.

Thanks for the tip. I'll keep this in mind.
