A novel mechanism concept for a fully flexible, motordriven, cam-actuated engine valve was reported in [1]. It is capable of i) variable valve timing, ii) variable lift and iii) individual valve phasing control. To check the validity of the concept in real engine environment, engine tests were performed using a single-cylinder of a modified sixcylinder 3.8-liter production engine, with the new ...

Due to the serious issues caused by air pollution and global warming, emission regulations are becoming stricter. New technologies that reduce NOx and PM emissions are needed. To cope with these social exhaust gas regulation demands, many advanced countries are striving to develop eco-friendly vehicles in order to respond to stricter emissions regulations. The homogeneous charged compression ig...

A broad class of mobile ad hoc network (MANET) applications will require every mobile node in a connected subnet to establish persistent paths with a single sink or gateway or command-post. Temporally ordered routing algorithm (TORA) is the only MANET routing protocol which has been explicitly designed to facilitate such a requirement. However, TORA has several shortcomings like i) the need for...

Constrained Nonlinear Predictive Control of Gasoline Low-Temperature Combustion — Combustion of a gasoline fuel with a high amount of recirculated exhaust gas is increasingly gaining interest. Such in part load conditions, a low combustion peak temperature can be achieved, which yields lowest emissions but suffers from instabilities of the process and a highly nonlinear behavior. These properti...
