Data for: Lean combustion analysis using a corona discharge igniter in an optical engine fueled with methane and a hydrogen-methane blend

Since the amount of data that has been acquired, processed and presented in the paper is non-negligible, the Authors decided to share, as an example, only two combustion points data.
Both these points are related to a lambda 1.4 air-CH4 mixture: one ignited by a conventional spark igniter, and one by an RF corona igniter. They have been acquired in the Internal Combustion Engine Lab of the University of Perugia, Department of Engineering.
Authors agree to share further data upon request.
-------------------------------------------------------------------------------------------------------
The shared data have been converted into an open-access format for sharing purposes: a .csv file for indicating analysis (only in-cylinder pressure is shown) and a .mp4 file (flame images).
The .csv files contain the in-cylinder pressure traces in 103 columns: the first one is related to the crank angle degree value (one row each 0.1 CAD), the second one to the average pressure trace, and each of the following 101 is related to the in-cylinder pressure of a single combustion event.
The .mp4 files contain the flame images related to one of the 101 combustion pressure traces reported in the corresponding .csv file. The temporal resolution is 0.3 CAD/frame, and the .mp4 speed, during the conversion, was set to 20 fps.

鉴于本论文中获取、处理并展示的数据体量可观，作者仅选取两组燃烧点数据作为示例予以共享。
上述两组燃烧点均对应当量比（lambda）为1.4的空气-甲烷（CH₄）混合气：一组采用传统火花塞点火，另一组采用射频电晕（RF corona）点火器点火。该数据采集自佩鲁贾大学工程学院内燃机实验室。
作者同意应使用者请求共享其余相关数据。

为便于共享，本次共享的数据已转换为开放获取格式：包含用于分析展示的.csv文件（仅展示缸内压力数据）以及存储火焰图像的.mp4文件。
该.csv文件共包含103列缸内压力曲线数据：第一列为曲轴转角（CAD）值，每0.1 CAD对应一行数据；第二列为平均压力曲线；后续101列则分别对应单次燃烧事件的缸内压力数据。
该.mp4文件包含与对应.csv文件中101条燃烧压力曲线之一相关的火焰图像序列。其时间分辨率为0.3 CAD/帧，且在数据转换过程中已将.mp4文件的播放速度设置为20 fps（帧每秒）。
