Spark-ignition engine

TL;DR: In this paper, the authors investigate the influence of exhaust gas recirculation on the tendency toward knock in a spark ignition engine and conclude that the main influence on the engine tendency towards knock is the end-gas temperature profile.

TL;DR: In this article, the performance of a turbocharged SI engine, firing with butanol/gasoline blends, has been investigated by means of numerical simulations of the engine behavior, and the main necessary modifications in the Electronic Control Unit have been highlighted in the paper.

TL;DR: In this article, it was shown that it is possible to start a neat methanol engine down to at least −30°C using the product gas from the cold start reactor described in this paper.

TL;DR: In this paper, the authors examined fuel film behaviour in general, the particular emphasis being on the application of fundamental experiments in an especially designed rig and numerical simulation to obtain a better understanding of film formation.
