Chinese engine identification
Does anybody know how to interpret Chinese engine model reference numbers?.
I know the first numbers appear to indicate capacity, but sometimes the number changes not because of different displacement but to indicate that it has a balancer. What do the letters mean, for example on a number like 156FMI?
So far I have this for the prefix numbers:
139 is 50 cc
147 is 90 cc
150 is 100 cc
152 is 125 cc horizontal engine (Honda Cub type)
154 is 125 cc " "
156 is 125 cc vertical or sloping single (Honda CG125 type)
157 is 125 cc vertical with balance shaft
161 is 150 cc
162 is 180 cc
169 is 200 cc

Hbing,
Thanks for re-translating the info... I know that takes a lot of work!
CC

Many thanks humanbeing. I'm amazed that something that useful can be deleted, but I've noticed that chinariders only keep threads for so long. Not a good idea, as a lot of knowledge and tips are lost that way.
Other forums have an archive so not everything is lost.

I think the above text translated by google is readable to native user finally. :mwink:
Translation to proper grammar will be done in my spare time slowly.

Re: Chinese engine identification
I have a E22 clone engine with the model # HW139FMB. This thread helped out some, but I can't seem to track down much information. Any additional info would be helpful! Thanks, -65Cub

Re: Chinese engine identification
hi i have a dirt bike but cant find out what engine it has can anybody help please
markings it has are E22 on one side and DJ152FMH *050704525* on the other what cc is it any one

Re: Chinese engine identification
E22 is a family of Honda engine | DJ often refer to http://www.dajiangmotor.com/about.asp | the cc can figured out by urself using above infos | *???* is just engine serial no.

Re: Chinese engine identification
167FMM
single, 67mm bore, air cooled, motorcycle engine, 250cc
You need the stroke to calculate the exact displacement.
The LF167MM claims it is at 64.5 for the stroke and that calculates to 227cc.

This could be set into a software program....it would read an engine code and then generate information.
It could be linked to documents that define it and even to include any licensing rights, it could be open or restricted based on the terms. I am not sure but patents expire with or over time. It could be linked to diagrams and parts and even detail how to adjust and even rebuild it.
The point is that all of this struggling to identify is unnecessary and so is the huge amounts of money spent on government regulators that are not really doing anything.

Re: Chinese engine identification
M in the sixth character place is for "water cooled" QJ469MS-A QJ Qianjiang 4 cylinder 69 bore M water cooled S 600cc A revision. should be QJ469MMS-A

Hmm I didn't know that, I'll have to update the diagram in my last post.

Re: Chinese engine identification
I wonder if you should, it may be just this one engine that is not conforming. actually you can add M for water cooling. But this QJ engine is missing the M in the 7th character place.

How did you know that it's water cooled anyway?
-
Re: Chinese engine identification
I seen it before the 250cc is 170MM and it is pretty consistently used./

Re: Chinese engine identification
The seventh character is what is not being covered if it is always M for motorcycle then what does L, Q, J and I signify
http://www.lifan.com/English/Industr...f-424d703b053d
something is not correct.
-
Re: Chinese engine identification
Maybe it's just being left out since it's kind of redundant saying that a motorcycle engine is for motorcycle use.
-
Re: Chinese engine identification
So you need to have under 7th character always M… but optional
163FML Forced air for F and L is 200cc ( M is used)
Then 170MM where M is water cooled and M is 250cc, but M is not their as above? ( M is not used)
The use of M consistently in the 7th character place is or could be an older convention, the later engines do not adhere to it.
-
Re: Chinese engine identification
I read it again unsigned is water cooled, sorry about that so the M still represent Motorcycle, so in cases were there are only two characters alpha(after the cylinder and bore) then it is water cooled.
So then....if in a computer program the code would have to insert a null character where the Chinese should have placed a "W", other wise it would not read the characters consistently.
should be YG170 MM
should be YG163FML

Re: Chinese engine identification
Ok I added that in.
I'd like make a form that could decypher all this automatically but I've totally forgot how to program :(

Re: Chinese engine identification
does not matter we can do it manually in our noggins.

1 - One cylinder
3 - 39mm bore diamater
9
F - Air colled
M - For motorcycle use
B - 50cc
A quick Google confirms this and that it's also a 4 stroke. There are 3 varients of this engine shown here.

Re: Chinese engine identification
Hello: I've acquired a number of engines but cannot decipher who made them or what they are. Can anybody help? The numbers are:
TZH152FMH 60607091
IP54FM1 51214377
LC1P391MA DC009900
LC152FMI FZ132484
152FMH 08064827
It's possible that some with a prefix of 1 could be I or vice versa. Any assistance would be appreciated.

Re: Chinese engine identification
Thanks very much for your reply: Do you have any idea of which manufacturers use the prefixes, "TZH", "IP" and "LC"?
