Performance simulation of a spark ignited free-piston engine

چکیده
Free-piston engines are under investigation by a number of research groups worldwide due to potential fuel efficiency and engine emissions advantages. The free-piston engine generator, in which a linear electric generator is fixed to the mover to produce electric power, has been proposed as an alternative prime mover for hybrid-electric vehicles. This paper investigates the performance of a spark ignited free-piston engine generator and compares it to a conventional engine using a computational fluid dynamics simulation model. The particular operating characteristics of the freepiston engine were not found to give noticeable performance advantages, and it is concluded that the main potential of this technology lies in the simplicity and flexibility of the concept.

متن کاملKnock and Combustion Rate Interaction in a Hydrogen Fuelled Combustion Engine
The paper describes correlation between combustion knock intensity and combustion rate calculated as the heat release rate from combustion pressure traces of a hydrogen fuelled spark ignited engine. Unlike a gasoline spark ignited (SI) engine, the hydrogen fuelled engine can easily generate knock during combustion at working conditions similar to a gasoline engine. However, the hydrogen knock d...
