Changfa Engines / Re: Slow rpm Chang fa?
« on: November 09, 2021, 01:59:17 PM »
Don't know if I should continue this thread or start a new one...is there an engine comparable to the Changfa that IS legal to sell in the US...that has similar reliability?  I am looking for water cooled, with an electric starter as an option...removable sleeves....

Thank you!  Is the S195 not allowed into the US now?  Can anyone recommend an honest place to buy one - so that I know that I want I am ordering is what I will get?  Does that engine use a removable cylinder sleeve?  It is nice to know that it will run below 1000 rpms.  Initially, I will need an engine to put out more power - use a gen head, compressor and a few other tools.  Once I get my place built, I can revamp the engine to run a 3KW gen head.

Thank you all!  A Chang Fa fits my budget at this point  ::)  Are they as versatile about fuels as the Lister engines, i.e. biofuels, waste oil, etc.?

Changfa Engines / Slow rpm Chang fa?
« on: October 30, 2021, 03:22:54 AM »
I am looking at websites for the Chang fa and related and I only see conflicting info - mostly look at the mfg page.  One part they say 800ish rpm and on another part of the same page they say something like 2,500 rpm.  Is there a Chang fa that is really a slow speed engine?

Listeroid Engines / What factors make it durable?
« on: October 29, 2021, 03:21:15 PM »
I like this forum - like the way you folks think.  Am I in trouble?   ;D

What makes them so durable?  The mass of the block?  Slow speed?  Dual pulleys to even the load?

Listeroid Engines / How much?
« on: August 26, 2021, 09:23:19 AM »
I hear people talk about listers being $2-3K.  I just got a quote from a company in India that showed a 10/1 as about $600.  What is missing here?

Listeroid Engines / Lister clones from China?
« on: August 20, 2021, 02:27:13 PM »
I have read through a lot of posts on this forum and have seen references to lister clones that are made in and sold from China.  I have searched Alibaba and madeinChina.com and could not find anything.  Are they sold through some other medium?

The last addition here was 2011  Many of the links posted here are dead.  Is this engine going the way of the dodo bird?

Lister Based Generators / Gen head with inverter?
« on: July 20, 2021, 08:54:40 AM »
I often seen generators advertised as being "inverters generators".  My understanding of that is that the inverter generator puts out a more suitable kind of electricity for computers and electronics.  Is the inverter portion of that similar to what used to be called a line conditioner?  an electric device that would prevent surges and clean up the electricity?

General Discussion / Re: A Pulley On Each Flywheel?
« on: July 20, 2021, 08:31:07 AM »
Thank you!  I am not sure which kind of clutch assembly I would use.  I just learned about these engines a couple of months ago.  I like what I have learned so far - the durability, economy and simplicity.  Cons - heavier than a "modern diesel" but I think I can accept that.  It look like something that I could take apart and fix myself, which is a huge plus!

So far, the optimal solution is: belt to air compressor; belt to generator (the generator will power charging for a 48v battery pack, as well as other tools); and belt to water pump;

When I get my specs drawn up I will be back with more questions.

General Discussion / A Pulley On Each Flywheel?
« on: July 19, 2021, 12:40:23 AM »
If I want a lister to power two machines at the same time, is it advisable to put a pulley on each of the flywheels?  Also, what about putting a clutch mechanism in each of the pulleys, so that one machine can be disengaged without fan belt follies?

General Discussion / Re: Utility trailer
« on: July 13, 2021, 03:58:13 AM »
Thank you!  Is there some way to "like" a response on this forum?  Good discussion from all of you.  The trailer mount is likely to be permanent.  Trailer is a little misleading.  I want it to be a flat platform that is powered by low speed (10 mph) electric motors, and remote controlled.  The first two years will be used extensively in construction.  After two years or so, I may switch out some of the tools that are no longer necessary, putting a much smaller compressor on it, a couple of 48v alternators on it (for back-up charging of PV battery packs - maybe even putting a 250 or 500 gallon water tank on it for distributing water.  The point is, the little lister will have two lives :)  I can understand the potential nightmare of direct drive, but I also see the benefit.  If running directly off the motor, a tool will have much greater potential - only limited by the load on the engine.  If running off of an electric motor, the tool will be limited to the power of the electric motor, regardless of the load on the engine.  Also, if the generator dies, nothing will be useful.  If pulleys can be attached to both flywheels, if one side goes down, I still have the other side to power things.   One of the reasons for putting a water pump on the "trailer" is for fire control - it is desert property.  A belt driven high pressure water pump can run a large gamut of power ranges - devoting the whole engine to the pump would help more quickly put out a fire.  If tools are belt driven, I can buy more powerful tools for the same $$ as a tool with an attached electric motor.  Lights, on the other hand, require a fixed voltage and wattage - they have to be run off of a generator or alternator - or a battery pack.  More and more tools are coming out in cordless versions - charging these has to be a generator/alternator function and it eliminates some of the air hoses that come with a compressor.  At least, this is the theory behind what I am thinking.  I have used generators before (engine attached to the genset as a set) but never had the option for anything more creative.   I envision having 4 devices hooked up directly to the motor: a compressor pump; a water pump; a 48v alternator set and a bigger generator (110v and more)

Sounds like a b eaut project and once set up will serve you for many years. Mounting the Lister on a trailer will do no harm to it but I certainly would consider a way to cover the engine from the elements when not in use and travelling.
Depending on which Lister you are considering as to what rating your trailer springs should be and if you only require a single or dual axles which would help us make a more informed reply.
There are many Listers already coupled to generators  of various sizes and would be perfectly matched engine HP to Kva. Ensure your arc welder is able to be run by the size generator you are thinking. Just meeting the specs of the welder will work but means that the generator will be working hard when your welding instead go a little bit bigger on the generator so it does not have to work hard and will last longer. Then all your power tools will work no problems. Even if you have air tools for the compressor depending on the size of the compressor, cfm rating, if the compressor can keep up supply.
There is a lot to think about and if you have all the tools then lay them out on the ground inside the size deck you intend for the trailer to see how and more importantly where they are best suited. A heavy engine and generator usually best over the axle then balance the load front and rear weight wise but still give easy access.
I would like to know more and see some pics about this project as it is an interesting one but sit down and do some sums on the amount of electricity you need to generate to make this rig work for you.
Thanks for the ideas.  So you are of the opinion that the lister should power a generator and that all tools should be powered by electricity from the gen?

General Discussion / Utility trailer
« on: July 12, 2021, 11:28:41 AM »
I am really intrigued by the Lister!  I would like to build what many people call a utility trailer or a tool trailer.  It will be a flat trailer with an engine, generator, compressor, water pump, arc welder and a set of relatively high powered lights.  My property is in the high plains desert and beyond what you would simply call "off grid", so this trailer will be used for construction purposes but also for maintenance and survival.  The Lister engines are quite a bit heavier than more modern engines but I like the fuel consumption, the low noise and rpms and the dependability of the Lister.  My questions:
1. Will the lifespan and performance of a Lister be negatively affected by being put on a mobile platform (assuming the trailer is designed for the weight.  I am guessing that the weight of the whole thing - including some hand tools, chains, etc will be about 2,000 pounds). 
2.  Do you think it is better to have the lister turn a generator and have each of the other tools powered by electric motors, or have a series of pulleys and belts turn as many of the other tools as possible (direct drive).  I will appreciate your opinions.
