"Dual Fuel" Deutz Tractor Powered By Raw Crop Oil

"Dual Fuel" Deutz Tractor Powered By Raw Crop Oil TRACTORS New Tractors 32-1-42 With a new dual fuel tractor engine from Deutz, European farmers can grow, extrude and burn their own crop oils. The Deutz Natural Fuel Engine was on display at the recent Agritechnica farm equipment show in Hannover, Germany. The design is available in two engine series, the TCD 2012 and the TCD 2013, and will be on the market by 2009. The Natural Fuel Engines have two fuel tanks. A smaller one is used for diesel fuel and the larger for rape or other seed based oil. The tractor starts on diesel. Coolant fluids are routed through the crop oil tank, heating it as the engine warms up. Once the raw oil reaches 158 degrees, the viscosity and flashpoint are equal to diesel fuel. This means it can be injected in the same fine spray as diesel for effective combustion. The engine will continue drawing heated oil as long as the oil's temperature remains at least 158 degrees F and the engine power output is at least 25 percent of the maximum load for more than 30 seconds. When operating on rapeseed or other oils, the operator must manually shift over to the diesel fuel before shutting down. This provides time for the system to purge itself of the raw oil, which could plug the ignition system once it cools. The operators can monitor and switch fuel sources from a terminal in the cabs. Ironically, both Fendt and Same Deutz-Fahr claim the distinction of being the first to introduce a tractor with the new engines. Fendt, for example, is introducing the new engine/fueling system in their 186 hp 820 Vario, while Same Deutz-Fahr is introducing the new engine in their Agrotron NaturalPower series with models rated from 131 to 184 engine horsepower.
