Fourth(IV) GENERATION - Propane Injection System

IV generation propane injection systems are designed for vehicles with fuel injection. They can also be used when the vehicles electronic systems ECU are complex and sensitive to any interference. They are one of the most modern systems in which propane injectors are used, dosing propane similarly as in the case of gasoline. Each injector of this kind of installation serves one engine cylinder thanks to which driving on propane basically does not differ from driving on gasoline. Installations of this type are usually fully automatic- even when there is no propane in the tank, the engine automatically switches to gasoline.

IV generation propane injection system hardly violates the fuel system, its proper assembling and calibration allows keeping functions of the original fuel system such as traction control system. Because of the fact that propanes octane rating is higher than gasoline's, calibration of the kits propane ECU enables to obtain the same or even better parameters while driving on propane. This is one of the most technically advanced ECU's on the market. Its calibration functions are almost completely automated thanks to which adaptation process is relatively simple.   

How does it work?

Liquid propane runs from the tank to the reducer through the liquid state filter and solenoid valve, which is open only when the engine runs on propane. propane pressure is reduced in a one stage reducer; propane evaporates (transforms from liquid to propaneeous state) and in this state supplies the injector's rail. Between the reducer and the injector's rail an additional propane filter is installed. It keeps propane injectors clean. The engine is usually started on gasoline and automatically switches to propane after it obtains programmed in ECU AUTOpropane parameters such as: speed, temperature, etc. In the moment of switching fuel injectors are switched off and propane injectors are switched on. propane dosage is controlled by the technically advanced ECU  directly cooperating with gasoline control system ECU, which as the primary unit has the main influence on the engine working on propane. Both cooperating systems decide about the moment and time of the injection- proper propane dosage in a proper time of the engine cycle. Gas  propane is injected to the cylinders sequentially.
