| Abstract: | Based on the micro-controlling of P87C552, the composing and operation principles of diesel / ethanol dual-fuelelectronic ejecting system are illustrated. Not only the design of hardware such as the expand of memory and the design ofdrive circuit, but also the realized methods of software, which including the measuring method of rotational speed, themethod to collect signals of fuel-feeding drag link displacement pick-up and the control method of injection pulse arediscussed in detail. The feasibility of this system is proved by tests. |
