Mini Single Over Head Cam V12 Gasoline Engine
« on: June 07, 2022, 03:20:50 PM »
Anyone remember this engine:


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.

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.

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.
