Design of the Compression Chamber and Optimization of the Sealing of a Novel Rotary Internal Combustion Engine using CFD 2020-37-0007
The increasing demand for lower fuel consumption and pollutant
emissions favours the development of novel engine configurations.
In line with this demand, the present contribution aims to
investigate the sealing performance of a new concept rotary
split-engine with a very promising thermal efficiency, a very low
NOx emissions' level, and a much higher power density than any
conventional internal combustion engine can. It uses the Atkinson
cycle, a low-temperature combustion process and when it uses two
pistons, symmetrically positioned around its shaft, it gives one
power stroke every 180 degrees. The main focus of this work is to
provide all the steps followed so far in order to ensure an
efficient sealing and operation of the compression process of this
engine, including the 1D & CFD simulations, CAD design &
optimisation, and experimental campaign for verifying the digital
results. The so-far investigation and experiments conclude that
this new rotary engine can work with no oil lubrication inside the
compression chamber and with much lower mechanical losses compared
to the existing reciprocating engines.
