Ignitability Study of a Spark-ignited Heavy-duty Engine, fueled with Natural Gas (CNG)
In-order to meet today’s stringent emission regulations of the European Union, the use of low-carbon fuels in ICE, for instance, Natural Gas (CNG)1 is on the limelight. Due to the high knock-resisting properties of methane (high octane rating), the SI (Spark-Ignition) combustion process is the best match with CNG1. A major disadvantage with an SI engine is its low thermal efficiency mainly due to
