Yes, like high end gadgets; iPhone comes to mind. Wake up, the west is making place for the east.

I've just bought and succesfully sold a lot of pakistani nippers and chinese barber scissors. They're amazingly well made and finished. Very good stainless steel.
Serious competition to the traditional and world bestselling brazilian nippers.

Would I install a chinese engine that I've never even saw on my boat?
Nope.
I wouldn't have a chinese car. Not yet.

Re: Chinese Diesel Engines

Electronics made in China whose standards are highly monitored by western corporations is one thing but Chinese engines where this is not the situation is another thing.

Given my experience with Chinese metalurgy, I doubt the price difference is worth the hassle of having an engine whose reliability is questionable and which is going to have a shorter lifetime. This is especially true if your safety is dependent on the engine working.

One day Chinese metallurgy might improve but they do not seem to be there yet.

All the downsides are not worth the savings.

Re: Chinese Diesel Engines

Yeah, Jedi,
One of the most powerfull corps in the world is closely watching that iphone, which is a premium gadget.

If the motor was FREE, NEW, and sitting in my cockpit, and the perfect application for my boat I wouldn't consider wasting my time installing it.

Never, Never, Never.

Re: Chinese Diesel Engines

Funny

People are bashing against chinese things and they dont even know that their 'American' car is made of over 50% components made in china and/or Korea.... just start looking where the components are comming from on your car.....

under proper supervision they can achieve desirable results....just a matter of finding the right production plant/design....

just my 2 cents...

While there are certainly qualitative issues with many Chinese products this is not universally true. Here in Guatemala there are a lot of Chinese products. Many are junk, but some are quite good. Specific product experience is relevant.

Case in point, I have a friend who works for HP. They manufacture ship loads (literally) of PCs there.

I expect that market pressures will force them to improve their QC over time...just as it did the Japanese electronics and the American auto industries.

WOW!!!! REALLY?????



I am old enough to remember common sayings such as "NO WAY WOULD I PURCHASE THAT JAPANESE JUNK" and I can also remember the litany Yanmar was up against when they were criticized for introducing cheap, light weight Japanese diesel junk!

It is about time that American engine manufacturers faced some real life competition for diesel engines. IMHO, the only reason American engines are so high priced compared to a gasoline engine is because they face limited competition. OK, so a diesel is heavier because of internal stresses but that just requires more iron. And as to machining, today's technology with computerized automatic machining should stifle that argument.

When I said "Never" it pertainted only to my above scenerio.

I'm aware that China could make it happen someday.

X100. Don't laugh, giving the Chinese a few more years, they will kick our ass. In fact, they already did. Soon our children & grand Children will all work for them if our children or grand children are good enough. They will love our cockiness and then beat us in our own game.

I crewed with a old Danish Captain recently. He told me just before the WWI, Germany made the worst product, everyone insists on Empire Made. Trust me, China will advance even fasted Japan.

Re: Chinese Diesel Engines

The area where Chinese made stuff really fails, is in quality control of metallurgy. Remember the Rocna anchors? Groco's made-in-china through-hulls that all had to be recalled because the bronze wasn't bronze?

I'd steer clear of anything Chinese-made where metallurgy is a critical factor.

Re: Chinese Diesel Engines

When considering Chinese made engines look at some video footage of rescue workers digging men out of mine shafts or digging people out of landslides,they always use Komatso , Cat,or some other type of heavy equitment..go to Alibabas website and type in forklifts and read the description of the product,most if not all have chinese made frames with Cat or Kubota power plants..If they(the chinese) wont use indigionus power plants I wouldnt either..

ISO9000 certification is just that: quality control. So, you could say that it would be wise to limit Chinese options to those that are ISO certified, just like Europeans are better off using only ISO certified US manufacturers et visa versa.

The Rocna anchors had a lower strength steel because Rocna told them to use that steel instead of the originally specified stronger steel. How people can insist on repeating that false info is beyond comprehension.

Re: Chinese Diesel Engines

Did you know that about 70% of all foreign students in the US are Chinese, according to a study published by the University of Illinois - Champaign/Urbana. If their universities were that good, how do you explain the massive student flights to US engineering and medicine universities? I attended electrical engineering school in Missouri. Many of my classmates were from China. They unanimously will tell you, that when they go back they have to revert to the "Chinese Manufacturing Practice", irrespective to what they've learned in the US. In China, if you stand-out you will be "eliminated"; free-thinking is never encouraged or allowed, hence the shortfalls in their QC and in manufacturing. Mauritz

Re: Chinese Diesel Engines

As a side note, after checking the webpage , the chinese still using cast iron crankshaft for hig load engine aplications instead of superior forged steel, i wonder if the rods are iron to???

Liners and pistons + rings looks nice in the pics , the engines looks like 20 years ago technology, i mean lots of pipes around engines , bulky design,
dont know how many tough working hours we can expect from one of this engines ,,, Overhaul at 700 hours Lol!!!
