    The common rail is like an air compressor but inplace air fuel is compressed once it rich a specific pressure it cutoff then this compressed fuel is feed to the injectors which are controlled with a ECU.

    Your demo rail, the one for the 5.9... it only has 1 injector connected. Where do the other injectors connect?
    I see the 5 other ports on the rail but I guess I just expected all the injector ports to be in a row. (I'm making the assumption that the 5.9 is a 6cyl)

    • @thoroughbreddiesel
      @thoroughbreddiesel  2 ปีที่แล้ว +1

      Yes and no, it depends on who is talking and what they are referring to. A pressure relief valve is often call a cascade valve or some people mistakenly refer to them as “race valves”. They can be fully mechanical or electronically actuated in some applications. Usually found in the fuel rail. A FCA or fuel control actuator (sometimes called a MPROP) is usually located in the injection pump and it controls the fuel pressure supplied by the fuel rail.

    So first let me say thank you for the video , Second I want to apologize right up front for my terminology or lack there of . Here goes . It seems to me that the injection pump is now just a high pressure pump which supplies fuel to the injectors all the same consistently . What I think happens next is the injectors are electronically operated when to open from some sort of command module . Compared to my p7100 pump which each injector has an individual line from the pump to the injector and then probably has some type of distributor mechanism these modern pumps only have to supply fuel to common rail and from there the injectors get there instructions from a computer ( I think ) . Though this greatly simplifies the responsibilities of the pump the weak link here to me is the computer for if it does not send out the right signal at the right time I don't think it could be good . Am I close here ??

      Depends on who you are talking to. Pressure limiting is the same as the cascade or overflow valve on the rail. Control valve is usually the electronically controlled portion of the common rail pump that controls the pressure delivered to the rail and injectors.

    One question no one seems to know the answer to. And a firm in Brighton called auto diesel marine a Bosch agent repairing injectors and repairing engines had no idea. How terrible they did not know the exact point in a Diesel engine when the injector fires. I’m after thinking about it, believe that it is either just after piston has reached top dead centre so as the explosion goes off it fires downwards. Or as piston rising from air intake stroke. As it’s pressurised in the rail, and if it was to be injected into the compressing air, I would think maybe when piston is 75 percent up and air not too hot yet to make Diesel go bang. My first answer I believe more though. Do you know?

    • @richardrichard5409

      That makes sense with the turbo being a mechanical device, and it's operation being sensed by electronics can be monitored. I drove it 200 miles yesterday on a good highway run. Even on 70% throttle, hard acceleration from a stop I'm getting less and less black smoke and more of a regular LBZ haze. I think it was just sooted up by the in town driving of the last owner's hugely in town use.
      One thing I found interesting on this drive is at exactly 9000 miles, the change engine oil level from the DIC came up, does this really mean that the DIC is not set for 10000 miles as a mileage ticker, and uses real world use engine parameters to decide?

    Hey Wade, an excellent overview of common rail injection systems but I disagree the "injector is the brain". As I believe you will agree (on second thought 😀?), an injector only does what it's told, in the case of my LB7, by the Fuel Injection Control Module, itself with instructions from the Engine Control Unit. Looking forward to future installments!

      Use diagnosis tools connected to ECU and measure amount of fuel from each injector and measure pressure in the fuel system. To find fault will take up to 30 minutes and some hours to replace defect parts. Greetings from car mechanic in Norway.
