I was back at the site this week that had the high pressure NG fuel injection on the 10,000 HP engine added a couple of years ago. I did the interlocks on the engine and another company did the injection. The engine runs much smoother and with lower emissions than any of the other ones with carburetors when all is right. The technology is pretty new, so they are finding issues. The injectors have 500 PSI NG on one side and directly inject into the head. They have had problems with the injectors sticking closed and found that the surfaces were too smooth. The manufacturer had to send them out and get them roughed up a little. They also changed countries of manufacture and had a lot of electronic component failures.
 
I will clarify the term carburetor. The previous design had a fuel valve that bled 50 PSI NG into the air stream, then A/F ratio was controlled by adjusting the turbo boost. The new system replaces the fuel valve with individual on/off valves on each cylinder, I am still controlling the A/F ratio with the turbo boost.
 
David, The more complicated the system the higher the odds of complications are. Small problems are multiplied in these systems. They have to be just about perfect to work so any small thing goes wrong and the whole thing does not work.

I am assuming the injectors will not work at all when they stick closed??? So what does this do to the performance of the engine??? I know you say that they injection system is more efficient when it is working correctly but what about when it is not??? While a carbureted system is never perfect it will function at some level even when it has issues.

I have 20 year old tractors that will still work if a pressure sensor fails. The operator just has to be observant until we can fix it. My son's newer tractors will not even move let alone run if a sensor fails. This is not progress in my book. You make the system more prone to small failures and then make it to where small failures shut the whole system down. That is the true meaning of "Catch 22" to me.
