Following the recently presented SP-110 FI TS, Sky Power GmbH is starting 2019 with another new product and presents the second newly developed 2-stroke engine. The SP-210 FI TS is based on the same engine concept and optionally can also be offered without system carrier.

The newly developed SP-210 FI TS with max. 8,2 kW at 5,000 rpm has a system carrier, just like the SP-110 FI TS, according to the company. This is mounted above the cylinders with the two electronic systems of the HKZ215 ignition and also the engine injection system. The injection system as well as the system carrier are screwed firmly together with the engine. All data lines of the sensors, which gather engine data at a variety of measuring points and transmit these to the ECU030, are bundled on the system carrier.

In the event of faults the system carrier can be dismantled complete, together with the injection system. A new system carrier with all modules and data cables can then be mounted and screwed together. Due to the passive ignition system, which is controlled by the ECU030, the engine is operational again after just a few minutes. “Consequently, the engine is extremely user- and maintenance friendly”, explained Karl Schudt, CEO of Sky Power GmbH. The engine is equipped with plug connectors from racing as standard. Plug connectors according to MIL specifications are possible as an option. At the request of the customer, the system carrier can also be left out, whereby longer cables are required and the integration of the engine is more complex.

As with the SP-110 FI TS, special attention was also given to designing the smooth running of the SP-210 FI TS. In addition, the objective was to achieve a fuel consumption as low as possible. “Just like with the SP-110 FI TS, our theoretical calculations proved to be true. The dynamometer tests verified the fuel requirement specified by us. At 5,000 rpm this is about 480 gr/HP/hour. Consequently, with this engine we will also satisfy the demands of our customers who are searching for efficient and fuel-saving drive solutions”, declared Schudt.

The SP-210 FI TS is available as a petrol engine. A Heavy Fuel (HF) variant will follow in the middle of 2019, according to Sky Power.
