1.Characteristics
(1) OBD-II Self-diagnosis function
- Service data monitoring
- Output of self-diagnosis failure code
(2) Fail-safe function
- Automatic switch to gasoline fuel injection in case of - - disconnection or short circuit of CNG injector
- Automatic switch to gasoline fuel injection in case of CNG pressure sensor and temperature sensor failure
- Automatic switch to gasoline fuel injection if the CNG tank pressure goes below a set pressure.
- Automatic switch to gasoline fuel injection in case of disconnection or short circuit of cut-off solenoid valve
(3) Basic performance
- Built-in ignition advance function (limitless ignition advance available)
a Output signal direct control, which is classified into the power TR signal control type or primary coil direct control type depending on the vehicle type
a Applicable regardless of the type of vehicle
a c The entire system is very stable as the turn on timing and the turn off timing are simultaneously advanced by a set degree at the time of ignition advance, the dwell time is always consistent regardless of the degree of advance, and ignition energy is stable.
a L Optimal ignition advance map for each operating area is applied.
- Produces power in CNG mode, which is equivalent to over 90% of that produced in the gasoline mode
- Starts the engine using CNG fuel at cold start and/or initial start-up (reduced emission during cold start and improved fuel economy)
