Sky Power's Wankel engine available for heavy fuel applications
Sky Power International's SP-180 SRE single-disc Wankel engine is now offered for heavy fuel (HF) applications
This Wankel engine is a hybrid electric motor with a compact design and class leading power-to-weight ratio. It was first introduced to the industry in 2017 and has since been installed in a wide range of drone applications.
The heavy fuel SP-180 HF SRE is a modified version of the original gasoline engine. This modification includes the SP-180 SRE with all auxiliaries and the additional of preheating equipment to compensate for the higher flash point of kerosene, and to maintain cold start capability.
Operational in several power modes
The heavy fuel SP-180 HF SRE can be operated as a direct drive, hybrid application or in electrical power generation mode. With hybrid boost power, an additional 15KW is optionally available for direct drive, depending on the capacity of the onboard battery. Conventional generators as well as starter generators are available depending on customer application and requirements with the latter having to be connected to a 48V battery pack with the preheater unit.
"Heavy fuel engines have a long history with us, as we have been offering our two-stroke engines in this configuration for a very long time,” explained Karsten Schudt, Managing Director of Sky Power GmbH. “Now, we are pleased to be able to use our Wankel engine for this fuel type, as well for military applications, notable the NATO single fuel policy.”
