Anyone remember this engine:

<a href="https://www.youtube.com/watch?v=inWZpHkyowQ" target="_blank">http://www.youtube.com/watch?v=inWZpHkyowQ</a>

Last September I posted it here. It's pity we couldn't manage to get it to production.

Engine is a dream. We didn't give up yet. In the past months, we designed a new machine and managed to control its cost in low level. Soon we'll launch it.

Wanna first share its first pictures here.

It's a Single Over Head Cam, and comes with water cooling, splash oiling, electric starter. We are also developing its CDI ( possible with ECU ).

Intensive testing will be carried out before launching.

Sid

hope the end of month we could test the sample, and deliver around end of August.

This engine is based on former one if you have saw the video.

Cost is around $2000 EX-work ( exclusive of spark plugs and ignitions ). It might come with CDI. This is under test.

Rhett

To clarify the mistake, check the pictures. it's a Single Over Head Cam Engine. There is a water pump. Camshaft and crankshaft are fully supported by bearings.

Jo · « **Reply #5 on:** June 11, 2022, 04:34:40 PM »

Would you like to tell us more about how you designed it Rhett ?

Your video about machining the Camshaft does not seem to be working. Have you got it set to private? Do you have any more videos about actually making the models?

Please keep in mind that we are not a commercial site so please do not put adverts on here but if members want to make contact with you directly about something that is not an issue.

Some parts are still on the way. Let's have a look at how it would look like in advance.

It would appear that "Youtube Shorts" type videos can't be played in embedded video.

Sorry but I can't watch most of the videos. When you record video with your phone in a vertical orientation it makes it seem like I'm looking through a keyhole when watching it. From what I saw of the full width videos your work is quite nice.

yes in future we need prepare 2 videos, one in vertical and the other horizontal.

Finally the camshaft comes. See how sharp it is. This one caused some trouble. The factory could not meet our precision. We have to find other supplier. It took some time.

as smooth as silk after break-in

Note the water channel, the dry sleeve, and the full supported crankshaft. Crankshaft is heat treated.

Looks very nice.
What was the tool used when installing the sleeves?
Looked to be some sort of induction heater?

Thanks, Sid

It looks like a glowplug from a diesel engine. Not so custom

petertha · « **Reply #23 on:** October 10, 2022, 12:03:09 AM »

In the spark ignition version you showed, what size/brand are the spark plugs? Have you settled on spark ignition vs. glow ignition or plan on offering both ways?

It's Spark Ignition (LSND 1/4-32), but you can turn it into a glow ignition engine. We don't plan to offer glow ignition for now.

Chuan Qi · « **Reply #25 on:** October 10, 2022, 02:32:40 AM »

Latest 2 updates. Engine is still under tweaking. The piston will upgrade to 2 rings. We'll turn all 12 exhausts spit fire.
