    Liquid Phase LPG Injector Calibration

    Hi Pat, Thanks for the feedback, I can appreciate everything you've stated. As with all fibre reinforced composites, material properties are highly dependent on fibre direction, length and dispersion. I guess my suggesting of GRP Nylon was a nod towards current industry where this material is...

    Liquid Phase LPG Injector Calibration

    Turbo: I was fortunate to read an SAE paper of yours yesterday: The Effects of Fuel Composition, System Design, and Operating Condition on In-System Vaporization and Hot Start of a Liquid-Phase LPG Injection System. In addition to the above paper I came across a few of your patents, of...

    Liquid Phase LPG Injector Calibration

    Hi Nick great to hear from you, I'm definetly interested! Maybe you can share some of your experience in this thread? Btw does your dog wear a hat and sun glasses?

    Jet Pump - EFI Fuel System

    Possibly f both pumps were pumping at the same pressure and capacity. In this instance the jet pump is using wasted power in the form of pressure from the EFI fuel rail, in fact most modern fuel systems incorporate a jet pump. Below is a description of the fuel system of a Z06 corvette, it has...

    Jet Pump - EFI Fuel System

    Good day everyone, I am hoping someone may be able to point me in the direction of some useful information regarding jet pumps. I am looking to design and manufacture a jet pump for the purpose of filling a container in an EFI fuel system. Below I have listed my objectives and the design...

    Liquid Phase LPG Injector Calibration

    Sorry for the delayed reply, been extremely busy with work this past week. I understand the logic behind the butane/gasoline injection strategy, my previous comments were regarding the filling infrastructure. I have not seen a commercial gasoline bowsers which is able to fill a LPG pressure...

    Liquid Phase LPG Injector Calibration

    Turbocohen, regarding the injector calibration I understand your situation, this is the exact motivation for my need to calibrate the injectors. I fully understand the P/T look up tables, it is a very elegant strategy to determine fuel composition. I have read numerous papers by a few Korean's...

    Liquid Phase LPG Injector Calibration

    Gentlemen, My apologies for the belated reply, I had stopped checking this thread a few months ago once it became inactive. Jzabs thank you for your input, it is interesting to hear the different methods used to realize a solution to this problem. From the commencement of this project I have...

    Liquid Phase LPG Injector Calibration

    franzh: I believe you are right. The only aftermarket product I have been able to find generous amounts of information about is the Icom JTG stuff. Initially I believed it was more sophisticated than I do today, that the Icom PCM varied the LPi injector pulse width based on fuel pressure and...

    Liquid Phase LPG Injector Calibration

    Good morning guys, I believe method 4 is the most elegant approach for a number of reasons: 1. There is no phase change, the LPG remains as a liquid which allows the N2 to be purged off as the volume is displaced by the LPG. This simply allows for delta mass to be calculated and converted to...

    Liquid Phase LPG Injector Calibration

    Gentlemen, Would anyone be able to share a method to measure actual injector pulse width (msec) vs volume flow at a fixed fuel pressure for a liquid phase (lp) LPG injector? I have come across eight Siemens LP LPG injectors used in the Icom JTG systems which I am planning to use in my own...
