Collection: Enjomor DOHC Engine & Parts

Enjomor engine company was founded in 2009 in China and we have been producing rc engines and stirling engines, internal combustion engines and so on since 2021. We have worked with e-commerce websites stirlingkit.com since 2021 and we ship worldwide on a daily basis.

Our new engine has been designed using the latest CAD software, prototyped and tested thoroughly. Cison v2 engine is our latest products, which are thought highly by our customers internationally. Cison inline four engine is the 2nd RC engine we are producing now. Of course, Cison inline four engines are in pre-order sales at stirlingkit.com now

Why we need your help

All our engines take months of designing, trying out various mechanical linkages and parts, and then building prototypes to perfect. Just like previous development of engines, it takes numerous design iterations to get to our final working prototype. We could start producing a small batch tomorrow and with a few weeks have a small number of engines built, but small batch runs are inherently expensive. Why is a small batch run expensive? All the parts will be machined on our own lathes and milling machines at our workshop. But the CNC machines first need to be programmed and set to run a batch of parts; usually taking hours for each component. CNC machines are not cheap, and it is industry standard to bill the set up time across the batch of parts. e.g. If the setup cost for part is $8,000 and you make 10 parts, then those parts would cost $800 + the raw material + the time to machine. But if 1000 parts were made the cost would drop to $8 per part + the raw material + the time to machine.

Tooling cost is a large cost. We need to design and machine tooling so our CNC machines can hold the raw material securely and to allow for quick, efficient machining. Designing the tooling carefully and making many parts at one time optimises production, meaning the machine can produce more parts faster. This reduces costs considerably. Making a good size batch also means we can save on material cost by buying in bulk. It won’t be a huge saving but it all helps. By increasing the batch size and optimizing tooling for more efficient machining we can attain in excess of a 60% reduction in production costs. So in summary we need your help to make tooling for all the components, and to spend the time to programme the CNC machines to make the components in the most efficient way.

With your help we can make the project (pre-order) a success!

Designed and Engineered in China

All of the parts for this engine are manufactured by us in our modern CNC equipped workshop located in China. This allows us to maintain very high standards, and gives us absolute control over the precision parts used in our engines. Cison engine Ltd was formed in China in 2000. And then we have continued to develop new and exciting internal combustion model engines ever since. We pride ourselves on producing stunning engines using excellent engineering. The 12 Years of ICE engine experience is shown in our engines.
