Advantages of the unscavenged pre-chamber ignition system in turbocharged natural gas engines for automotive applications

In view of the increasing restrictions for CO2 mitigation, evaluation alternative fuels to ensure sustainability transportation is becoming increasingly important. Since some these alternatives can be refined from renewable sources, they are interesting perspective both: use current power-plants and emission. this sense, natural gas arises as an propellant substitute fossil fuels. Therefore, combining fuel with specific combustion strategies help decrease environmental footprint in broadest sense. paper, possible advantages combination has been conducted. The investigation carried out a port fueled turbocharged spark-ignition engine, using compressed (CNG) passive pre-chamber ignition system. effects CNG properties on have analyzed global impact appraised by means life cycle assessment. Results show that different sources not only reduces emission but also contribute remove existent pollution. addition, increase engine thermal efficiency when concept.
