Homogeneous charge compression ignition (HCCI) seems to be the most promising solution for gasoline engines in the light of future emissions regulations. This novel combustion technique allows for significant reduction of fuel consumption and engine-out NOX emissions at low and medium engine load/speed conditions. High heat release rate enables realization of the Otto cycle close to ideal, incr...

Engines equipped with camless valve trains will have greater space for performance optimization. In this paper, based on the electromagnetic actuated valve train system, one-dimensional and three-dimensional simulation models on engine thermodynamic cycle and in-cylinder charge motion are established, respectively. With the application of early-intake-valve closing (EIVC) strategy，unthrottled l...

Over the past 25 years, natural resources have been used up quickly, causing significant damage and contamination to planet which is earth. Tribology, a new technology for keeping power parts running, supported extremely fast efficient coal oil-powered machinery throughout history. Many different kinds of resource reserves, like those parts, will be gone in century. Revolutionary zero-emission ...

This Thesis concerns the development of fullerene-like (FL) carbon nitride (CNx) thin films and the discovery of phosphorus-carbide (CPx) compounds. The work dedicated to CPx include first-principles theoretical simulations of the growth and properties of FL–CPx structures. I have employed DC magnetron sputtering methods to synthesize both CNx and CPx thin films. The deposition conditions for C...

Increasing fuel economy in modern passenger car engines has become one of the primary development targets, due to swiftly increasing raw oil prices. Initially, vast progress was achieved in the development of the combustion process. Computer Aided Engineering (CAE) has been one of the keys to success; however, further potential is now being investigated. Currently, the primary focus of engine d...

The global automotive industry is undergoing a significant transition as battery electric vehicles enter the market and diesel sales decline. It widely recognized that internal combustion engines (ICE) will be needed for transport years to come; however, demands on ICE fuel efficiency, emissions, cost, performance are extremely challenging. Gasoline compression ignition (GCI) one approach achie...
