TL;DR: In this paper, the effects of injection timing and spark timing on engine performance and NO x emission were investigated under wide engine loads under a single-cylinder test engine using a high-pressure gas injector, and the results indicate that direct injection of hydrogen prevents backfire and high thermal efficiency and output power can be achieved by hydrogen injection during late compression stroke.

TL;DR: The possibility of establishing a hydrogen-fuelled compression ignition engine has been investigated experimentally using a conventional swirl chamber diesel engine as discussed by the authors, and the results indicated that ignition and engine operation are satisfactory without any ignition aid.

TL;DR: In this article, a single-cylinder direct-injection diesel engine equipped with a common-rail injection system and a cooled EGR system was used to find strategies for extending the load range of pre-mixed charge compression ignition-based combustion.

TL;DR: In this paper, a laser homodyne technique is applied to measure turbulence intensities and spatial scales during compression and expansion strokes in a non-fired engine, and the relative fluid motion in a turbulent flow is detected directly without cyclic variation biases caused by fluctuation in the main flow.

TL;DR: The experimental results on fuel-spray development and combustion characteristics were affected by the properties of biodiesel fuels (BDFs), which may support potentially the optimal design of diesel engine fueled with BDFs.
