Nice videos Ronald, thank you.   Thanks, back ya .  You're welcome.

Nice dyno too. looks like an old Clayton portable. No, Not a Clayton. I Goggled Clayton PTO dynamometer and nothing came up. You are good with Google what did you find on a Clayton PTO Dyno??. I said it LOOKS like an old Clayton – didn't say it was. I think those are called agricultural dyno's, which are made by many manufacturers.

Could have sworn you said you would never do that unless you were pre-paid. If you will reread my post 13, it states how you won the video. It sounds like a couple of phone calls compelled you.

Did I send you a check? Hmm, no.    If you will reread my post 13, it states how you won the video. Ditto.

Anyway, you performed a pretty good lab experiment, which is what it was – a lab test under controlled conditions, You got to be kidding me !!! LOL, now that is funny !!!. Ya got a tractor setting in front of a shop bay door, in direct sun light, hot summer day, (8-10-2011. zip code 23322).  And you call that a Lab Test Under Controlled Conditions…… Hmmmmm…lol. Yep. Ok, For some reason I was thinking that engines that were ran on a dyno in a Cell were considered Dyno Tested Under Controlled Conditions???. Yep, those meet SAE and ASTM conditions – very controlled.    which, and I'm sure you'll agree with me, Sorry, not yet?. The only thing I had control of was how hard I wanted to twist it’s tail (load). I didn’t have any control over intake air temperature, exhaust back pressure etc, etc,etc..  Well then I guess you don’t believe those things effects how a fossil fueled engine performs?. Same tests are performed on natural gas and gasoline engines too.   has little bearing on the physical world. No, that is one of the beauty's of a PTO Dyno. It’s as close as I can get to real life conditions without trying to run beside the tractor with a wrench in my hand.  LOL. Good analogy. 

Or maybe you're making the statement that Chinese diesel engines are exempt from certain operating norms. No, I am not trying to make any type of statement. This is your Ego Thread Sorry, I try to leave that at the door. I was invited to by you so you can set me straight and I ended up giving you what you ask for. Yes, exactly, almost.

The ball head in the governor and the rack are barely doing anything in your demonstrations. That’s another Funny !!, LOL. Ask for a Video and don’t even know what you are looking at. I know you want believe this either but,…  There is enough sound in the Dyno video to hear the engine go into a smooth full throttle (2450 rpm, engine rpm spec taken off front crank pulley) . If the governor is not working at all ….. you will never get the engine rpm off of base idle when you push the throttle.  If the governor is working and/or have a problem with the fuel rail or available fuel,  same similar engine performance results …. really!.  You can also hear the engine get pulled into a full load and hold it (meaning the engine was running smooth under full load) .. If the governor or fuel rack was out of adjustment/broke etc, or if the injection pump fuel chamber was not full….. it does not take very much of a engine load before it falls or try's to fall on it’s face (cut off/miss,flutter etc. starving for fuel. maybe you get the idea?.) . I know this statement ain’t worth much either but, when fully loaded the governor weights where slung out as far as they could go and the the fuel rack was pulled as far as it would go with a full fuel chamber.  In the last part of the dyno video you can hear me load the engine down below it’s power curve (tip, rpm’s start to fall).  The engine can’t do that with improper fuel supply or control. It was trying but at the same time it was saying I ain’t got not more. Meaning I am sucking in all the air and fuel I can and if you keep going I will stall/cut off. That dyno can handle up to 115 hp (considered small one) which means you can bring 115hp to its knees. Let me know what you find on that Clayton pto Dyno. It appears that Clayton was bought out by Mustang some years ago but some still do exist.

In the physical world, say plowing a field or “brush-hogging”, the rack and flyweights will be on a roller coaster while maintaining engine speed under widely and rapidly fluctuating loads. Now you know about plowing / bush-hogging, OK. Nope, I know absolutely nothing about the technical aspects of them other than they can cause very rapid changes in the governor demands which cannot be duplicated by manually moving the rack or turning the wheel on a dyno. The video without the dyno shows rapidly fluctuating flyweights forced by rapid throttle demands. Sorry, you can't duplicate an instant stall like coming against a rock. On the dyno video…….  as steady load is applied the weights sling out and pulls the fuel rack. Hard to check that running beside a tractor plowing / bush-hogging. But at the same time you could bet 50 cent it would plow / bush-hogg if the engine will hold full throttle & full load on a dyno for 30-45 minutes after it reached full field operating temp.

Unfortunately you can't see this because it's all inside. (there is a nie Plexiglas model at the Woodward school – check it out). Doubt if I check it out, but maybe you should check out a different school model and then apply what you think you know and see if it is applicable to this tractor?.

I think you are saying that it is nothing more than a superfluous check valve. No. I am not smart enough to use big words like that. The average reading comprehension in the US is eighth grade level, so I am guilty of the crime of trying to better myself. Truth is simplicity – sometimes you can say with one applicable word what would otherwise take a paragraph. I speak like I do with my peers.

You will become very famous if you can convince Bosch, CAV, Kiki, Stanadyne, Cummins, Cat, Detroit, Mack, et al. to eliminate the fuel pressure regulating valve from their fuel systems. No, not wanting to be famous. This Chinese tractor does not have a injection pump made by any of those manufactures you listed ????. Perhaps not but I guarantee they are exact copies, and if I could read Chinese I would have listed them too.

There are an awful lot of people besides myself that think and know they are completely necessary. I have NEVER stated the check valve in this tractor was not necessary. Please provide link and post number. You alluded to it and even went to prove it with your videos.

PS: I thought you were going to read up on diesel fuel systems? Please provide link and post number.  None, it was my suggestion.  Guess you didn't yet, otherwise we wouldn't be having this discussion. This is not a discussion this is a all about you topic and how dumb I am. ?? I don't think you are dumb at all.

Addendum: My wholehearted apologies Ronald on some of the personal comments I made, even though they may be taken out of context. Don’t need or want your apologies .   I want to know how you really feel.  Okay: I respect you and I actually like you. I like doing business with you and your company. I respect your deep understanding of the Chinese wheeled tractors, and you provide excellent technical and sales support to those of us that need it. There is also no doubt in my mind that you are a good father, husband, and local community supporter.

I believe I was still a little miffed over your trolling me in on the pressure gauge issue. I see, if someone don’t agree with you……  you are getting trolled. Hold on. LOL. Ya, that's my fault.

Now that I look back, I have to laugh at myself for getting suckered in like that.  How could you have been so stupid ???..crazy. Again, my fault.

I think that one of these days I'll go back and get my high school diploma, or take a GED test or something… So all this self profaned (look up “profaned”) so called high profile job, education and super pay check is not true?. Nope, it's true. Maritime academy gpa was 4.0, all courses at Calhoon Engineering School 90%. Have the documents. o’well….it’s the internet.  I am sure you will let us know how it goes.

Working on another video…. you got me started. I'm glad, those videos are great. Keep up the good work. As for the controversial valve, I digress.

All of the concrete work was included in the price of the building so I won't really know until next week, but I kinda think not. I'm just glad it wasn't more serious. The time it would take a mechanic up there with a new air compressor, you would have nine yards of set-up concrete in the drum.
