Part of the Heat and Mass Transfer book series (HMT)


In this paper, the authors report on a combustion technique that is applicable to direct injection, internal combustion engines, both Diesel or gasoline fueled. This technique is based on porous medium (PM) combustion technology. Theoretical considerations are presented for internal combustion engines, indicating that an overall thermal efficiency improvement will exist for the PM- engine. This is explained and the general performance of the new PM-engine is demonstrated for a single cylinder, air-cooled direct injection Diesel engine. Initial results are presented and an outlook is given on how the present developments might continue in the future.
