THOR 190 EVO HF clutched version with electric starter

POLINI THOR 190 HF As its Thor 200 HF older brother, the Polini Thor 190HF has been developed by the R&D team using the new 3D modeling software systems and flow dynamic simulation. The result of this research and the introduction of the innovative HF System grant better cooling improving the performance of the Thor 190HF. Polini THOR 190 HF engines feature: 193cc displacement, reduced weight till 12,3 kg if equipped with Titanium exhaust system (available as an optional). Technical features: “HF” COOLING SHROUD The new design of the “COVER” cooling shrouds optimizes and accelerates the incoming flows and increases the exit power towards the propeller. Together with the air forced system it grants great performance in terms of cylinder cooling. SPARK COOLING SYSTEM SCS is the innovative cooling system of the spark plug that lows the working temperatures in the point of highest warm and in the burning chamber, eliminating the events of over-heating. Polini SCS system reduces the EGT temperatures till 100 C° and till 50 C° the ones under the spark plug. HEAD The new profile of the burning chamber improves the propagation of the flame optimizing the fuel combustion phase. This peculiarity, together with the increasing of the compression ratio, increases the engine performance reducing the fuel consumption. TRASMISSION Belt transmission with 2,83 reduction ratios. The belt is made of special mixture with the aim to increase the grip, to reduce the servicing, to improve the stability, life and power output. To reduce and contains vibrations a new crankshaft with distributed and optimized rotating weights has been designed for this specific transmission system. 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. SPECIFIC POWER UNIT The light alloy casting cylinder has a 193cc displacement, 64mm bore, 600mm stroke. It offers the best performance with 27hp of power at 8000 rpm., even with the highest working temperatures. Its liner has a nickel-chrome coating for the best piston sliding. The piston is made of gravity die-cast light alloy at high silicon content with 2 special chromed and nitride steel rings. The new profile improves the performance and reduces the piston wear. EXHAUST SYSTEM The exhaust system is completely hand made for a better product quality. It is divided into two sections with manifold with spherical connection and fixed on natural rubber suspensions that grant longer life. The exclusive new springs with steel hooks make them stronger and offer the possibility to be better fastened. The exhaust system has a compact design and contained dimensions to reduce the weight. The small overall dimensions improve the aerodynamic and grant a low noise level. FUEL SYSTEM Walbro carburetor with specific setting and air box. This setting, grants both a power increase at 8000 rpm and more constant power output. The Air Box with the new inlet holes grants a noise reduction and makes the setting easier. FRAME CONNECTIONS To make the assembly on the frame easier, the frame-engine connecting points of the Polini Thor 190 HF are the same as the other engines: Thor 80, Thor 130 EVO, Thor 200 HF and THOR 250. FLASH STARTER  It is made of carbon steel material by Polini which grants longer life. To improve the fixing, M6 screws have been used. The other models of THOR 190 HF are equipped with: – POLINI THOR 190 HF with CENTRIFUGAL CLUTCH Thor 190 HF is also available with the centrifugal clutch studied to grant the maximum safety features during the engine preparation, take-off, flight and landing. This model weights 14,4 kg. It includes the Flash starter. – POLINI THOR 190 HF with MANUAL and ELECTRIC STARTER Thor 190 HF is also available with electric starter without centrifugal clutch. This model includes the battery charger and a 12V electric connection for the flight instruments. This model weights 14,9 kg. The engine comes with battery, starter relays and throttle control. – POLINI THOR 190 HF with CENTRIFUGAL CLUTCH, ELECTRIC STARTER and manual FLASH STARTER The full optional model fits the centrifugal clutch, flash starter, electric starter, 12V electric connection, battery, relay, and throttle control. This model weights 17 kg.Even richer range of Thor engines presented by Polini Motori. In occasion of the Coupe Icare Expò 2014 Polini Motori presents in preview the brand new Polini THOR 190EVO HFfull optional, which is the most complete of this range.

Supplied with electric starter and centrifugal clutch, this is a very performing engine with really reduced weight of 17 kg and a comfortable drive.
TECHNICAL FEATURES
PURE TECHNOLOGY - Polini Thor 190 engine features advance technical solutions; dimensions, power torque ratio, 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.
TRANSMISSION - 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 tension.
SPECIFIC POWER UNIT - The power unit with 193cc displacement, 64mm bore and 60mm stroke, is made of light alloy. It offers the maximum performance with 27 hp at 7400 rev/min. even at the maximum working temperatures. 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.
EXHAUST SYSTEM - The exhaust system is completely hand made for a better product quality. The muffler has been designed to achieve a compact design, contained dimensions and reduce its weight. The reduced overall dimensions improve the aerodynamic and grant a low noise level.

THOR 190 Light

The great success achieved with the Thor paramotor engines hasnt stopped the research and development of the Polini Motori technical department. Light, reliable, compact and powerful here it is the new range of Polini Thor 190 Light engines: three different models that among them stands out the new one with centrifugal clutch.

Its 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.
