Fuel system for diesel drive unit has two ball valve which mix fuel with ball valve for diesel fuel completely open and ball valve for vegetable oil completely closed in initial position

摘要

Fuel system has ball valves (7,8) which mix fuel. Ball valve for diesel fuel is completely open and ball valve for vegetable oil is completely closed in initial position. Both are connected to ball valve by control lever and linkage. Stepless control actuates baud train. This control could also be effected over gear wheels on ball valve and rack resting against both gear wheels or chain. Depending upon adjustment of the stepless control, fuel mixture changes proportionally up to the pure fuel. The fuel arrives over the feed pump (6) at the heat exchanger (5), which warms up the fuel over the engine cooling system. From the heat exchanger the fuel arrives over the filter (4) at the injection pump (3) and then at the diesel unit (2).
