| Popis: | The present data article is based on the research work which investigates the low-temperature combustion (LTC) in a dual fuel light duty engine. The LTC mode was activated by means of double pilot injection to control the energy release rate in the first combustion stage, thereby minimizing the increase of the rate of pressure and allowing the operation under LTC. This data article presents all the data which supports the choice for double pilot injection vs single pilot injection for that research. In this experimental work the engine was fueled with diesel, in full-diesel (FD) mode, and in dual fuel (DF) mode with natural gas and natural gas - hydrogen mixtures as main fuel. In DF mode the pilot diesel fuel was injected both with a single and a double injection at the same engine speed and torque. The pressure cycle in one of the four cylinders, the intake manifold pressure and the injector current signal were acquired on a crank angle basis for 100 consecutive engine cycles. Analysis of combustion rate, maximum pressure rise and fuel/air flow rate were performed. The data set, which also includes some engine control parameters, the combustion chamber geometry and some injector features, can potentially be reused to numerically model the combustion phenomena and, in particular, to investigate the effect on the ignition phase of combustion in LTC, also considering the variability from cycle to cycle. |
