It’s a two stroke 193cc engine, with really reduced weight of 13,2 kg, transmission with belt gearing-down, compact dimension but powerful. It has been designed to meet the needs of the “pilots” who are willing to use a really performing engine of reduced weight. Project and approval required many tests and many hours of flight to grant the best performance and safety requirements. For the most exigent pilots a model with electric starter and a model with centrifugal clutch and flash starter are available.
Polini Thor 190 engine features advanced technical solutions; dimensions, power torque ratio, reduced vibrations, performance of climb, innovative and compact design, but, above all, everything has been studied to grant the best weight-power ratio, studying every single part in order to reduce its weight.
Belt transmission with 2,83 reduction ratio. To reduce vibrations a new crankshaft with distributed and optimized rotating weights has been designed for this specific transmission system. In order to resist to the belt strength, a special bearing has been housed on the transmission case side. It can stand a transversal load 10 times higher than the standard roller bearings. It lets the belt have a constant stretch.
The power unit with 193cc displacement, 64mm bore and 60mm stroke, is cast in light alloy. It offers the maximum performance with 27 hp power at 7400 rev/min. even at the maximum working temperature. The cylinder liner has a nickel-chrome coating for the best piston sliding. The piston is gravity die-cast in light alloy at high silicon content with 2 chromed and nitride steel rings.
