Hello, and at the end of my publication on a 0.2 cc diesel engine, I would like to present you with drawings of its parts. Tolerances and fits are not specified, and are performed with the highest possible accuracy in your conditions. For your information, the prototype (in the video) worked for...

Hello, I answer: with the help of a dial indicator, beating is controlled on limit switches with a diameter of 3 plus minus 0.002. It should not exceed 0.02 mm. This will ensure that the liner and shaft axes are square. The indicator is installed horizontally in the holder, and by turning the...

Hello, as promised, a few files of my rig: 1-forming the edges of the crankcase and boring the hole for the cylinder. Shanks D-3 mm for aligning the perpendicularity of the cylinder axis to the shaft axis. 2-drilling and boring the diffuser seat. 3 - turning the crankshaft crank and similarly -...

My grinding head is installed instead of the tool holder, speed motor 540-12V, grinding wheel D-50x8. The shaft is installed in 4 bearings with clearance adjustment in them.

Thank you, the cylinder liner and crankshaft are made of steel with 0.4% carbon and 0.8-1.0% chromium, both parts are hardened, the crankshaft is tempered at 250 degrees C. There are no coatings. After heat treatment - grinding with a caliper grinding head (homemade) and lapping the liner...

Maybe, good luck to you

Thanks, so I will

Thank you all for your kind words and appreciation of my work. Drawings of all engine parts are available, as well as mandrels and accessories, which are in the photo, but I can offer you only not earlier than Monday. The problem is still - I can not insert PDF files into the text, but only a photo.

Thanks, yes, when designing the engine, I proceeded from the concept of AE0.1 and 0.2 cc engines, but only in the external design and technological features

I present a drawing of a general view of my 0.2 cc engine, maybe anyone is intereste

Thank you, I'm an old mоtor-mechanic, from 1975, I've redesigned, refurbished and refined many different model engines, but this one was built from start to finish. All manufacturing operations were thought out and performed as expected.

Hello, I am from Ukraine, I am 64. I would like to present to your attention my first engine. It has a volume of 0.2 cc and a cylinder diameter of 6 mm, stroke 7 mm, weight 23 grams. For its manufacture, only small homemade lathe was used. The structure was drawn in SolidWorks. The engine has a...
