The causing a fuel mark. So what’s happening with a fuel knock well the injectors firing fuel either a little too early or a little too late, and, it kind of misfires, and it’ll give you a knocking sound. When you’re not used to hearing. Now if you’re getting smoke, you can try doing a cutout test if you have access to that and try to identify which cylinder it is. You could also try removing the exhaust manifold. If it does, it’s a certain rpm. You know rev it up, see if you can find out which hole is, you know, usually in a when it’ll emit like white smoke.
If it is a diesel engine fuel mock now also I get a question on 3126 is a lot. And it’s a two starting on 26 that has a weird knock noise under heavy to medium to heavy acceleration. And I would say If you’re used to the truck and it’s always done this. That’s kind of indicative of 3120 sixes. They have a weird fuel mark to them. Now if it’s a new sound you’re not used to getting that checked out. But I call 3126 is crackly I know it’s not a word, but that’s kind of how they sound when they’re under medium to heavy acceleration sometimes they have a weird injector clack, that is a that’s just how they fire, and I’ve seen several 3126 is like that so say if you just bought a 3126 you had to check that everything seems okay. It might just be how it sounds I wish I had a recording of what it sounds like, in the shop right now.
So that’s kind of discussing, you know what to look for if your engines ticking, or knocking, or tapping. You know what it can be what the causes can be, you know if it is polos vowel covers, it’s easy to do on pretty much every engine, and you’re just looking for big damage. Usually, you can see without removing any components. You know, try to get it fixed, as soon as possible because usually, takings turn into bigger damage. A little thought experiment there was just to show you that a very large engine, even running at very low relative RPM, that makes a lot of torque can make horsepower easily at a low RPM range.
Now they are limited though, in their capacity to reach rpm. If you could rev that 15 liters up to the same 31,000 RPM, you’d be making 1000s of horsepower. But you have to remember the small engines have lighter weight components and typically that enables them to reach the RPM necessary to make good horsepower. It’s just they’re not producing In a flat torque curve like diesel would necessarily so don’t go putting the 600 horsepower, one-liter engine in your truck and thinking it’s gonna last long either the lightweight nature of the components would probably not last very long making that amount of power.
Don’t try to rev that big diesel up though past 2000 RPM or possibly worse things could happen. There was simply to show you that an exceptionally huge motor, in any event, running at low relative RPM, that makes a ton of force can make torque effectively at a low RPM range. Presently they are restricted, however, in their ability to arrive at rpm. On the off chance that you could fire up that 15 liters to a similar 31,000 RPM, you’d make 1000s of pull. Yet, you need to recall the little motors have lighter weight parts, and commonly that empowers them to arrive at the RPM important to make the great pull. It’s simply they’re not creating In a level force bend like diesel would fundamentally so don’t go putting the 600 pull, one-liter motor in your truck and believing it’s going to keep going long either the lightweight idea of the parts would presumably not keep going long creation that measure of power. Don’t attempt to fire up that enormous diesel however past 2000 RPM or conceivably more regrettable things could occur.
