The Thor 190 EVO is the latest version of this engine. The initial teething troubles have been overcome and the engine runs more powerfull and reliable than ever. Due to its low weight and high performance, this engine is predestined for ambitious and sporty paramotor flying.
The exhaust is specially designed for this engine and entwines elegantly around the engine to avoid turbulence in front of the propeller. The multi-part construction is the result of many years of product care and guarantees durability and little maintenance.
The lightweight belt transmission uses the reliable Poly-V belt technology. 2.83: 1 was selected as the reduction ratio, which means that the maximum power of the engine can be used. A centrifugal clutch is also used for the belt transmission.
The "spark cooling system" (SCS) from Polini lowers the working temperature in the combustion chamber and thus prevents overheating. The exhaust gas temperature is also reduced.
The 1.25 m propeller from Helix Carbon, perfectly matched to the engine, is made of unbreakable, carbon fiber and meets the highest safety standards. Compared to other propeller manufacturers, the Helix Carbon propellers are particularly characterized by their smooth running and the much more efficient blade profile.
The flash starter, revised by Polini with a reinforced spring and housing, enables a comfortable engine start. The starter spring buffers the energy required for starting during the tightening process and releases it suddenly when the maximum is reached. As result, the engine starts immediately.
Thermal stability is achieved by the cooling fan. The streamlined engine cowling directs the air flow, generated by the radial fan, through the cooling fins to the cylinder and cylinder head.
The Walbro carburetor is a membrane carburetor. The advantage for the experienced aviator is the possibility to fine tune the mixture depending on the altitude of the take-off site very easily. The fuel pump is integrated in the carburetor and the small size saves weight. The position of the carburetor is independent and therefore it cannot overflow. Trouble-free operation is guaranteed even during extreme flight maneuvers.
