Abstract
Wankel rotary engines (REs) are often used for unmanned aerial vehicle (UAV)
applications due to their excellent power-to-weight ratio and their smooth
operation. Existing RE propulsion units are mainly designed to run on
high-volatility fuels like aviation gasoline or regular gasoline. However,
specific applications require a jet fuel or even multi-fuel capability. Due to
their geometry, the low compression ratio (CR) of REs prevents the
implementation of compression ignition (CI) combustion processes. While
publications of modified spark-ignition engines that are able to run on
low-volatile fuels are already few in number, publications of heavy-fuel
spark-ignited (SI) REs can hardly be found at all.
The purpose of this paper is as follows: The operation of a SI RE operated on
kerosene is discussed. Accordingly, a thermodynamic analysis is carried out at
warmed-up operation with kerosene. It is shown that sufficient performance and
power output can be achieved on kerosene for full-load behavior. Furthermore,
cold-start tests are carried out to investigate the limits of kerosene
operation. Therefore, a low-temperature test bench is developed that allows the
investigation of engine starts down to −30°C. The challenges of mixture
formation for heavy fuels in port fuel injection systems for REs at cold-start
conditions are investigated and discussed. It is demonstrated that cold starting
a SI RE down to −25°C is possible with correct measures.
