The best engine of Soviet mopeds was created by a village self-taught

The dream of boys in the USSR was a motor bike, but simply a moped. This is the only type of motor vehicle that did not require a driver's license to drive. The mopeds were equipped with special motors of the series D, modifications starting from D-4 and before D-8. Few of us knew that this engine was created by a rural carpenter and also an amateur designer.

At the beginning of the 30s, the first motorcycles of the USSR were created and, as a rule, on the basis of foreign samples, there was simply no own design school. Along with powerful motorcycles

lightweight models are also created "Arrow" and "K-1B" "Kievlyanin"

Models based on bicycles were also created, but not a single development reached serial production for various reasons.

In the early 50s, an amendment appeared in the traffic rules, obliging the owners of all motorcycles to obtain a driver's license. For people without a driver's license, it was decided to create bicycle motors with a displacement of less than 50 cubic meters. cm. They tried to use foreign experience ("

Irtysh", "MD-65"), and also came up with their own various layouts.

The operating experience of these developments gave a deplorable result - there were much more laudatory responses to complaints.

Against the background of this absurdity, an interesting model of a Kharkov bicycle factory appears with an engine created by a rural carpenter. Philip Alexandrovich Pribyloi.

Where did this self-taught Kulibin come from?

Philip Alexandrovich from a young age was fond of various mechanisms. A watch was brought to him from all over the area for repairs. Having studied the device of the camera, I assembled a homemade one from a matchbox. I wanted to ride a bike, but there was no money to buy it, it doesn't matter: I made a frame from wood and adapted wheels from a mower. There was no chain or sprockets, so I used a belt drive. After graduating from the 4th grade of a rural school, he began to work as a carpenter. I was able to buy a real bike with my salary. At the age of 18 I saw a motorcycle for the first time and decided to make a gasoline engine for my bike.

So many things happened in the process of creating the engine: they exploded and ended up in the hospital, but each time the engines turned out to be better and more powerful. When the next modernization of the engine turned out to be quite reliable, I decided to show it to the creators of bicycles and drove it to Kharkov. The motorbike rumbled and smoked like a steam locomotive, but developed a very decent speed. The young designer only had enough courage to reach the gates of the bicycle factory. After standing a little in front of the checkpoint, he was ashamed, turned around and went home.

Fortunately for him, the chief designer of the bicycle plant looked out of the window of the plant management - he was very much interested in the source of the incomprehensible rumble. Seeing the motorcyclist driving away, he sent the service driver in Pobeda after him.

For a long time, engineers could not believe that the engine was created by a self-taught carpenter. From that day, Philip Aleksandrovich Pribyloi became a full-time employee of the plant, a foreman of the experimental workshop. At the workplace, colleagues tighten up his education: he learned to read drawings, carry out calculations and was engaged in improving the engine.

In 1955, the plant produced an experimental batch of 300 bicycles with motors "D-4". The engine had a compression ratio of 5.2 units, ran on gasoline A-56, A-66 and developed a power of one horsepower and consumed only 1.2 liters of gasoline per 100 km.

The Moscow Commission highly appreciated the development of the Kharkovites and it was decided to mass produce such an engine at the Leningrad plant "Red October". Here are the memories of the factory workers of those years:

We instructed our plant to master the engine of the Pribylye. A sample was sent from Kharkov. We did exactly the same. They began to turn him on. And it won't start. Kharkiv starts up, but ours does not. They fought, fought - not in any! Then Pribylyi was summoned to Leningrad. He has arrived. Shy about everyone. He looked at our engine and said: “It’s clear, it won’t start! There's a dirochka in my carburetor! " Our engineers ask: “Why is she? There are no such holes in any carburetor. " - “That encore knows her! Tilka won't start without a dirochka. " We went to the Polytechnic Institute to see specialists. They laughed: “Nonsense! No hole needed. This is due to technical illiteracy. " And the fact remains: with a hole it starts, without a hole - no.
And, marveling at this incident, the guy said goodbye to us and left ...

In the early years, the engine was sold separately for installation on citizens' bicycles. Only in 1958, at the Kharkov Bicycle Plant, the first moped specially made for the engine was released "D-4". The model was named "B-901"

After him, the production of mopeds on D-4 engines was mastered by other factories.

This is how the development of the modern Kulibin-Philip Alexandrovich Pribylyi received a ticket for a long life. Simple and reliable, like a Kalashnikov assault rifle, the engine has served many generations. Even after the collapse of the USSR, the engine did not die, but continues to be produced in large quantities... in China.
