All hello from Russia! There was a wish to show the project to foreign colleagues on this hobby. For mistakes in spelling I ask to forgive as I don't know your language and I write through a site translator.
In the project was engaged a little more than half a year, now it is complete completely and I will try to lay out its main parts on you court. As I don't possess extensive base of machines that and quality of production of details corresponding, all was made almost of garbage.
Piston/sleeve. The piston self-made, served as a material a brake support from the car, well I didn't find at work of the necessary diameter of aluminum and melted the piston into a tube, further preparation was processed on the lathe and ground in to a sleeve manually. Diameter of the piston 19MM. The sleeve - the pumping-up pump from diesel TNVD, is more exact than it the case was sawn and polished inside, there is a small honingovka. Piston ring - sanitary rubber.
The cranked shaft - one-basic is made also on the lathe, the crankshaft isn't balanced (balancing will be then if the project lives to a final stage). Piston stroke - 18мм. The crank is pressed in a cheek of a cranked shaft in the hot way.
The cylinder head in the first version was made of aluminum (at that time got hold of the necessary piece), and was compound - saddles of valves were from bronze. But such design when saddles and a separate detail directing the valve was difficult in grinding in and as a result I didn't manage to grind in the valve and the head went to a garbage can. It was made new completely of bronze, channels and openings directing the valve are more precisely drilled, in a consequence it and got used almost hermetically. The valve are made of self-tapping screws with long naked part, at the self-tapping screw it is possible to tell an ideal facet, got used very well. On a photo new head at the left and old on the right. Well and photo of valves.
If it it is possible to call the block so, support of bearings of a cranked shaft are more exact and the case to which will be fastens everyone and everything also fine-molded and welded electric welding. In it two ball-bearings on which actually are installed and the cranked shaft rotates.
After that came to make time a camshaft. Made a start from gas distribution gear wheels as their size had a direct bearing on a design of all mechanism of gas distribution. I made cams, pushers of valves, yokes and were aggregated by everything.
Spark plug also self-made.
Ignition system classical - contact and transistor from the truck. The system was hidden in an engine box support, the key of inclusion of a food and a nest of the plug of the accumulator are removed.
The carburetor can be told standard for self-made engines. Preparation of a mix happens from saturation of air soaked up by the engine by vapors of fuel.
Well here it seems the main parts also I described if that missed that ask and I will try to answer. The engine was painted and cultivated, installed on a support and is ready to start.
Here video of its work. I will be very glad to your comments and manuals, yours faithfully from Russia.
