CONTROL CIRCUIT OF INJECTOR WITH CUT SOLENOID OF LPI ENGINE, METHOD OF CONTROLLING CUT SOLENOID, AND METHOD OF TROUBLESHOOTING CUT SOLENOID

摘要

PROBLEM TO BE SOLVED: To provide a control circuit controlling injectors with cut solenoids capable of meeting the requirements of various related laws and regulations without causing air pollution by effectively cutting off the leakage of a fuel from the injectors into the atmosphere when an LPI engine is stopped, a control method of controlling the cut solenoids, and a troubleshooting method of determining whether the cut solenoids are defective or not. SOLUTION: This control circuit of the injectors with the cut solenoids of the LPI engine comprises the cut solenoids installed in the large number of injectors, a power supply commonly connected to the cut solenoids, an electronic control unit for controlling the cut solenoids, and a control line connected between the electronic control unit and the cut solenoid.
