Listeroid Engines / Re: Catalytic converter to reduce exhaust odor
« on: February 27, 2020, 09:39:13 PM »

cujet,   long time !  :)

To my knowledge a Cat Converter only works on gasoline emissions.
Diesels must use a Diesel Particulate Filter (DPF) which also reduces odour considerably.
New diesels have a fuel re-burn system which introduces fuel into the hot exhaust stream just downstream from the engine to create additional combustion in the DPF. This helps to burn the particulates and partially clean the DPF. Eventually they do clog.
In the case of my diesel the "regen" burn cycle lasts approx 10 minutes every 7 hours of driving.

I heard somewhere that in Europe they have a fuel additive which changes the diesel exhaust odour to something less offensive.
I have not researched to see if anyone here carries it in North America.

cheers,

just got a few with external antenna so i can build it in an enclosure.

regards bernhard

If you have any programming issues or need some help to get up and running send me a PM  ;)

WiFi range.
I have seen a few tests on youtube where users reached 350 ft (clean line of sight) using the Wemos /Arduino module.
It uses the ESP8266 wifi chip and does have an onboard antennae.
I use mine at 75 ft without issues. In one application I added a wifi extender (booster) to my system approx 100ft from the main router.
That enhanced the coverage considerably.

The big difference with the Wemos is that it's pins are all 3.3vdc (like the raspberry Pi) unlike the Arduino which is 5vdc.

Do you see some advantage in that?

I think there are a few boards that have the built in Wifi now.


Nope, No advantage to 3.3 volts. Just pointing out the differences in the boards.
Some people make the mistake of assuming the Wemos is the same as an Arduino in all respects and fry the board by using 5vdv sensors and inputs instead of 3.3v.

Very thoughtful that you gave the two engines a window so that they can view outside while working  ;D

You may already be aware, but the arduino "uno" and "mega"do not have WiFi capability.
If you wish to communicate with the system from the house, take a look at the Wemos D1R2.
Form factor and programming language is the same as Arduino but it has WiFi connectivity.
It even uses the Arduino programming software.
Costs around $10
The big difference with the Wemos is that it's pins are all 3.3vdc (like the raspberry Pi) unlike the Arduino which is 5vdc.
Buy local from Amazon. (As you know, ... EBay is not shipping from the Asia at the moment)
Make sure it's the Wemos D1 R2 . The older Wemos D1 has been phased out but there may still be some old inventory being sold.

Amazing amount of work being done (and man/animal power being saved) by a single piston.

It's unlikely that you will need water injection on a continuous basis so consider an algorithm to intermittently dose the engine.

Yep. Have a look at this earlier post where we see Changfa's earning their reputation.

Listeroid Engines / Re: QUIET Exhaust - Listeroid - HOW?
« on: February 18, 2020, 07:35:57 PM »
Yes, the official Lister design using an underground concrete chamber is very effective.

I recently added an Arduino to my lister.
It monitors the engine coolant temperature and RPM using an infrared sensor to a white dot on the flywheel.
The Arduino sends the data to a cloud application so my cell phone can monitor it when I'm not in the garage.
(It will be running for up to 5 hours per cycle as a CHP system and I will not always be nearby).
My phone can communicate with the Arduino also, as part of my phone application I added a kill button.

If the engine senses overspeed, (or If I hit the kill button on my phone for any reason), the Arduino energizes a solenoid which closes the fuel rack until the flywheel rpm is zero..
It also allows me to have the engine run for a set time and then have the arduino turn off.
In the picture below you can see the Solid State relay attached to the right side of the Arduino enclosure.
That relay energizes the shutdown solenoid.

You could just as easily have the relay activate the water injection pump when the coolant temperature reaches some desired set point.
You could also use this same logic to active a fuel switch-over valve after 'x' minutes of running or after the engine shows some heat.
In reverse, the arduino could switch the fuel back to diesel 'x' minutes before auto shutdown.
Whatever you want.  ... As long as you are having fun !  ;D

Also below is the 12vdc fuel switching valve that I will be using to switch from diesel to WVO (Currently my fuel switching is manual).
A second relay will be added to the Arduino to accomplish this.

That method of timing looks about right.
Give it a try.
You will have to find a way to mark your flywheel at approx 20 deg BTC and then adjust your initial spray point to either side of that mark depending on the engine specs and the fuel being used.

Hi Oldsid,

Welcome. Looking forward to seeing some of your projects.
That's a lot of engines. !

Everything else / Re: Mid Brusnwick Green Paint Match Offer
« on: January 27, 2020, 12:43:24 AM »
Not sure if this helps...
A few years ago I went to a paint shop and had them blend a quart of paint according to the Lister colour spec.
Somewhere I had found the components of mid-brunswick green.
Below is the modern CIL paint spec for this colour. Any paint shop should be able to make some from this label.
I used it to paint my Listeroid.

No guarantees that it exactly matches the original Dursley Lister colour.
I have not been able to find a genuine Lister to compare colours.

That's a really good price.
I have 2 of these engines on small generators.
Very reliable little units.
