Government regulations and the growing awareness of the general population about the impact caused on nature and human health by the pollutant emission from automobiles have increased the demand for a more environmentally friendly solution for the future of mobility. Considering the high cost of electric vehicles, the negative environmental impact of their battery production due to mining, the long charging time and, above all, the fact that 65% of the global electricity is generated by fossil fuels, the relevance of further developing internal combustion engines fueled with biofuels is unquestionable. Lately, the turbulent jet ignition (TJI) system has been intensively studied as a means to reduce specific fuel consumption (SFC) and pollutant emissions from engines. Both active and passive TJI are endowed with high ignition energy allowing the spark-ignited engine to run with lean mixtures and low covariance of IMEP.
