A piece that may be worth little to those who don't like cars or mechanics, but a true object of worship for aficionados who will be willing to pay around 5500 euros for a replica of this Stinger 609 engine. Each cylinder of the tiny V8 engine has 12,5 ml of displacement and the diameter x stroke ratio of the pistons is 10 x 9,7 mm – to give you an idea, the same measurement as the 1.0 engine in the VW Up is 74,5 x 76,4 mm.

A worthy competitor to the smallest V8 engine in the world?

In addition to the Stinger 609 engine, from the American company, the Toyan Engine, a Chinese company specializing in miniature components for the automotive sector, has developed its version of the smallest V8 engine in the world, which is basically a toy for big people big enough to fit in the palm of your hand.

The tiny V8 engine works perfectly like the traditional one and is built in a reduced scale of 1:10. The miniature can even be disassembled so that anyone can check its details or the functioning of the mechanisms, in addition to facilitating any possible repair. However, in this case, the owner must have the appropriate tools for adjustment.

The engine has only 28 cylinders, which are numbers far removed, of course, from what the original scale engines deliver. For reference, a Ford Mustang Coyote has 5.000 cc. The tiny V8 engine rivaling the Stinger 609 engine generates 4,25 horsepower, being fed by two carburetors, water-cooled and reaching up to 12.500 rpm.

Youtuber builds the world's smallest Wankel engine

YouTuber JohnnyW90 recreated a miniature Wankel thruster. Unlike many other scale models, the rotary engine built by Johnny is almost perfectly functional. On the first attempt, in fact, the air-fuel mixture in the tiny carburetor was too lean, resulting in the little carburetor shutting down. engine.

The solution was a double carburettor and so the little Wankel engine finally worked perfectly. The model can rotate between 4 and 14 RPM, something that is achieved in a very short time.

 Named after its creator, German engineer Felix Wankel, and perfected by Mazda, the rotary engine was abandoned with the end of production of the RX-8. Since then, several conversations about his return have happened sporadically. One of the rumors that makes the most sense is using a Wankel engine, which runs very smoothly, as a generator to power the batteries of electric cars.
