Abstract
The invention discloses a double-line oil supply device for a bus. The device is mainly composed of a diesel engine, a diesel box, an emulsified diesel box, an emulsified diesel solenoid valve and a diesel solenoid valve; an output tube of the diesel box is connected with the input end of the diesel solenoid valve; an output tube of the emulsified diesel box is connected with the input end of the emulsified diesel solenoid valve; and the output end of the diesel solenoid valve and the output end of the emulsified diesel solenoid valve are connected with each other, then connected with a diesel engine return tube and a diesel engine injection pump return tube, and then connected with a diesel engine transfer pump inlet tube. A better effect can be obtained when the emulsified diesel solenoid valve and the diesel solenoid valve are replaced with two-inlet one-outlet solenoid valves. After the refit, the bus uses diesel while a low-temperature start and uses emulsified diesel while running. A three-month trial of two urban traffic air-conditioning buses indicates that the average fuel saving ratio can reach 17.46%; the average emission value of exhaust smoke is 0.321m-1, which is farther lower than the limit value 3.0m-1 of a trial diesel engine so that the emission reduction effect is obvious; and therefore, the double-line oil supply device for the bus is widely suitable for urban buses.
