Research & Development

In addition to the development of existing engines, the Świątek company is carrying out new projects, the most important of which are: a power bench for altitude simulation (temperature and wind), as well as the “INNO-LOT” project, a hashtag composed of INNO- (innovation) and -LOT (from the word “lotnictwo” – aviation in Polish). The aim of this project is to create an engine that consumes kerosene, but in the Beau de Rochas thermodynamic cycle (which means, it will be a spark-ignition engine), and not in the Diesel cycle, which should keep the engine a reasonable weight.

Experimental monocylinder

An experimental monocylinder turns on the bench with a modular cylinder head, in order to test different forms of the combustion chamber. But the elements of the future engine are gradually taking shape; we were able to show at the RSA meeting in Brienne-le-Château a four-cylinder model:

Prototype VJ-115 Gdi

The prototype uses a VW block, aluminum cylinders with steel sleeves, instead of cast iron (94 mm bore, 82 mm race), and separate liquid-cooled cylinder heads. The injection will be direct, and the compression will be 50% higher compared to existing air-cooled models.
From the point of view of thermodynamics, this engine will – of course – be less efficient than a diesel engine, but it will be much less heavy.
In its atmospheric version, it will have to reach 115 hp (and why not 109 hp), in turbo version, we expect 140 hp.
