i have seen old tractors that started on gasoline then when "warmed up" switched over to kerosene > from all the people who experineced the use of these tractors ,mention the fact that black smoke rolled out the exhaust when running on the kerosene >compression then was not much above 6 to 7 and the ignition systems were primative but the idea worked >when turning off the tractor you had to switch back to gasoline for a few minutes to empty the kerosene out of the fuel bowl and let it refill with gas so you could restart the tractor easily on gas> International havester has a daul fuel gas/ diesil engine >there was one here localy up until a few years ago it was in the 70 hp range >some one with better computer skills than mine could perhaps reseach the archives to get a better understanding how this worked >in europe dual fuels have been around for many many years in trade school we were shown,very large industrial units the ran on diesil or natural gas so this technology has been around for some time >whether its a advantage or not ,thats open to discussion>In the late seventys propane and natural gas conversions were popular > the bonous was cleaner air, but a lot of poor convertions led to fires and explosions of the vehilce plus the filling staions were not convienant and led to the demise >although the price of lpg and ng were cheaper and cleaner the program faded J
