Abstract

169,766. Dodson, E. June 22, 1920. Spray carburettors.-In a multi-fuel carburetting system for an engine in which variations of the power are controlled by the throttle, a fuel of low self-ignition temperature such as paraffin is used when the engine compression is low and a fuel of high self-ignition temperature such as alcohol is automatically brought into use when the engine compression is high. As shown in Fig. 1, the paraffin is supplied from a tank B to a submerged jet B<3>, air entering at B" forming an emulsion with the fuel. This is drawn into the air-supply pipe B<9> through the Venturi tube B<8> and the mixture enters the main air pipe A at a second Venturi A<2>. The alcohol is supplied through the pipe C, and is controlled by a valve, which may be interlinked with the throttle. A starting-fuel may be supplied through the pipe E, and additional fuel may be admitted through the pipe F when the throttle is fully open. At low compression, the paraffin mixture is drawn in; on increased suction the Venturi B<8> limits the supply of paraffin so that at high compression and full throttle practically only alcohol is being used. In a modification a three-way cock definitelv shuts off the paraffin mixture supply as the alcohol pipe is opened and vice-versa. In a modification, the paraffin emulsion is formed in a perforated tube B<16>, Fig. 2, the air thereto being admitted past the valve B<15>. Air is added to the emulsion in a Venturi tube B<18> and the mixture passes through the chamber B<20> and the Venturi tubes B<22>, A<7> to the main air passage way A. An exhaust jacket surrounds the paraffin-supply device in both modifications. Any fuel that is not vaporized when it enters the chamber B<10> is heated therein and drawn through the holes in the Venturi tube B<22>. The alcohol is supplied through the raised jet G<2>, the suction on the jet being controlled by a. secondary air inlet G<5>. The two fuels may be supplied by pumps, actuated through variable levers to control the quantity delivered. The means for varying the leverage is interconnected with the throttle valve.
