Here is the machine. Lets take a look closer to the cooling system.
This engine is still using Air/Fan Cooling system. Why Kymco is still using this technology on 150cc CVT engine? According to some article on the internet, 150cc CVT engine will produce higher heat than can not be cooling down by only Fan System. It can only using Liquid System. May be there is some secret that Kymco try to offer to us.
See picture above, It said KMAP (Kymco Magnesium Apply Production). According to the Kymco.com.tw, this machine using Magnesium-Alumunium alloy. What I know is this alloy is superb light. Key to Nonferrous said that this alloy will be more cooler. And the most amazing is, this is aerospace technology. Damn, from where does Kymco has this technology!
Back to the heat. If this alloy can release heat better than other alloy, then may be Kymco calculation is correct, that this machine do not need Liquid Cooling system. The answer is simply, because this alloy is cooler.
May be this Fin will help the cooling process. Air flow coming from this fin will flowing to the back. Blowing the hot air backward that blowed by the fan onto the engine surface.
Look at the bottom of this machine, you will see the secondary air that control the emission. They put it on the left side, differ than other type that put on the right side. But this will not effect the emission, because it just only the placement. Left or right is just the same.
Wait, something strange with the muffler.
There is a bolt on the muffler. What is this bolt function after all? I read on some bike magazine. To test bike emission, it should be plug some device on the front, middle and the rear muffler, so the test will be more accurate. May be this bolt is a preparation for this test. If so, then this is a great functionality.
Another feature that I like is, they put a plate in the middle of the shock absorber to protect the electricity from water, sand and dirt, so it will not come up. Yup, I'm so amaze by this, because this is very clever solution to protect the electricity when the road is not in perfect condition.
On the mid stand there a cube that make the stand to stop on the proper place. I think this is funny, because of the shape. Another question is, how strong is this cube can hold up to the high pressure of this machine weight plus the rider when they sit on?
I call it a safe hook, just like SR-125. Why I said that, because when you park this machine and lock it. You can place your stuff on this hook and lock it by pushing it. Your stuff can not be remove until you open your handle lock and this hook will release automatically. Unless they cut down your stuff tie.
The key is just like JR-100. It does not have a shutter key yet! I don't know why, because SR-125 SE+ has this feature. Last I remember that in Taiwan this product had launched before the shutter key invented by the engineers. But if they launch in Indonesia, I said this will be a step back technology. Because in Indonesia, SR with shutter key function is launched before Techno. This key has a great function. Turn to left end to open the baggage and turn to right end to open the gasoline cap.
The speedometer is so futuristic, but I'm so sorry I can not take a good picture of it. May be picture from kymco.com.tw will be a perfect to describe it.
This speedometer is a combination between analog and digital. Speed on the above are analog. The RPM meter are digital, sign by a light that will light the bottom indicator. Odotrip, watch, gasoline capacity are also digital.
The mirror design is very unique and exclusive. See the arrow. When I saw it, first thing in my mind is, "is this mirror had broken?" But when I look closely, it not. This is like a two piece alloy that joined together. The engineers made this mirror is so good, event I do not know how to plug this mirror, I don't see any nut on it. May be they cover it. Very interesting.
Last thing I want to said that the seat has a writing "Techno GT" that same design as the sticker. Cool.
It's good work ai_zeus.
ReplyDeleteAbout the bolt on the exhaust pipe, it should be connected with a pipe to the air pump (but it's removed) for the purpose of better emission control. This device called "Air Injection Reactor" (A.I.R.). A.I.R. reduces the products of incomplete combustion (hydrocarbons and carbon monoxide) by injecting fresh air into the exhaust manifolds of the engine near to the exhaust valves. In the presence of this oxygen-laden air, further oxidation occurs in the manifold and exhaust pipe.
Generally the air is delivered by pump (sometimes called a 'smog pump') driven from a belt off the engine through tubing and valves to the inlet manifold(s). To prevent backfiring a diverter valve is used. When the engine is coasting this valve vents the air to the muffler (silencer) and at high engine speeds allows excess air to escape through a relief valve. Non-return valves prevent exhaust gasses entering then pump.
This technology was introduced in 1966 in California, and was in use for the next several decades. It is not generally in use subsequently, having been supplanted by cleaner burning engines and better catalytic converters.
I saw on the Royal Enfield 500CC (made in India), the classics very old technology, but the brand new made year 2004, with digital ignation and of course the smog pump, etc.... etc...
But,,,,,
There is some debate as to A.I.R. effects on the exhaust valves. Some owners claim that the system has kept their exhaust valves clean and prolonged their life, others have blamed them for burning out valves and seats. This appears to trend with the brand and engine configuration, and may be affected by each implementation.
A.I.R. systems have been known to cause exhaust manifolds to glow red (incandesce) due to excess heat.
A.I.R. systems cause increased back pressure in the exhaust. Some engine combinations are more sensitive to this then others. Usually higher revving engines or those with high performance cams that include increased valve overlap.
A.I.R. systems do cause some parasitic drag on the engine, but despite criticism from many backyard mechanics, they cause very little loss of engine power, typically around 1-2 hp. This amount is unnoticeable except through repeated testing and is incidental to the usual poor tuning in older vehicles. Gains from removal are typically either psychological or due to an improperly maintained system.
My opinion, Kymco do the right thing by removing the smug pump.
I hope this comment will enrich your information about motorcycle world especially for Kymcos.
Keep writing Bro.....

Welcome on board.
ReplyDeleteThank you so much for your knowledge shared, I'm very pleased. I think Techno using A.I.R that you mentioned. The system inject fresh air after the valve open as you can see under the bottom of this machine.
What I'm thinking is, the bolt position is in the middle of the muffler, not on the front. What I know is, A.I.R working in the best performance when they've put on the front muffler when the smog is out from the combustion chamber. So, the smog can be quickly react with the fresh air especially with the Oxygen and the Hydrogen. The result is cleaner emission.
I don't think the engineer would put the A.I.R on the mid muffler. Cause the result would be differ if you put on the front. And it such a weird decission if they has made a hole for the A.I.R, but they unplug it.
Getting more interesting.
Nice review, Ndri. Well done!
ReplyDeleteThank you boss Soyuz. Feel so happy if someone helped by my writing.
ReplyDeletei think it is not for A.I.R. i think it is for O2 sensor for EFi equipped engine. Kymco doesn't want to waste money making two different type of exhaust system. So they make 1 exhaust system that can be applied to both type engine
