TL;DR: In this article, the in-cylinder flow structures in a vertical plane at the center of cylinder were obtained both within the piston bowl and within the squish volume, during the compression and expansion stroke.

TL;DR: In this article, a detailed information about the engine modifications which result in improving the overall efficiency and extending the maximum load of the engine is presented, and control-related problems associated with the higher loads are also identified and appropriate solutions are suggested.

TL;DR: In this paper, a 12 L six-cylinder heavy-duty engine with port-injected ethanol was ignited with a small amount of diesel injected into the cylinder, and the setup left much freedom for influencing the combustion process and resulted in a combustion resembling that of a homogeneous charge compression ignition (HCCI) engine with high efficiency and low NOx emissions.

TL;DR: In this article, the authors outline and discuss the key elements of an EU industrial development policy consistent with the Paris Agreement and assess the current EU Industrial Strategy proposal against these elements, and propose a framework for the purpose of developing and evaluating industrial policy for net-zero emissions.

TL;DR: In this article, a comparative technical and economic assessment of promising future fuel/vehicle combinations is presented for light duty vehicles, i.e. passenger cars and light trucks, which account for approximately half of global transportation energy demand and a major share of carbon dioxide and other emissions from the transport sector.
