FORD TRACTORS AND CONVERSIONS AT THE BLUE FORCE WORKING WEEKEND IN WILTS...

More action from the Blue Force Working Weekend held at Coombe Bissett in Wiltshire in September 2013

The tractor used a 20 hp (15 kW), inline four-cylinder engine. The engine used to be just like the Ford mannequin T engine in many respects. Like many engines of its day, it was once multifuel-in a position; it was usually tuned for gas or kerosene, but alcohol could also be burned. (Tractor vaporising oil [TVO] existed in 1920 but was once not yet extensively used. It entered broader use within the 1930s and Forties.) Like many other multifuel machines, the Fordson began on gas from a small auxiliary tank (just a few quarts) and then converted to the primary gas tank once warmed up sufficiently (not more than 5 minutes[8]). To control the kerosene (or, not often, TVO), the intake method had a vaporizer downstream of the carburetor. The blend coming from the carburetor was intentionally rich, and the vaporizer heated it and combined it with more air to lean it out to the ultimate ratio earlier than getting into the inlet manifold.[9] The consumption approach additionally had a water-bath air cleaner to filter the dust out of the air inhaled with the aid of the engine[10][11] (an invention that did not originate at Ford but that used to be still alternatively novel in 1917). Air cleansing is relevant to engine lifespan, even for avenue autos and most above all for farming and building autos (which work in environments the place grime is usually stirred up into the air). The Fordson carburetor and air cleaner have been designed via Holley.[12] In later many years, the water tub would be replaced with an oil bathtub for higher filtering performance.
