“…In the first case, called Engine Matched to the Fuel, commercial gasoline is combusted in a modified CI engine while in the second one, named Fuel Matched to the Engine, the ignitibility properties of gasoline are modified to be able to be used in a market available diesel engine. 19,20 The Engine Matched to the Fuel GCI variant is still under development at Aramco. Preliminary results showed CO 2 similar to the one of a diesel engine.…”

The pressure to reduce CO2 and criteria pollutants of internal combustion engines (ICE) powered vehicles is higher than ever. The existing gasoline and diesel engine vehicles face a critical challenge to adjust to these stringent demands. By combining a clean fuel like gasoline with a high efficiency thermodynamic cycle (compression ignition), it is possible to create a powertrain that is clean both globally and locally thus breaking the historical trade-off between decreasing CO2 and reducing criteria pollutants. Recent works have demonstrated the potential of higher reactivity gasoline (HRG) fuels to reduce NOX and particulate emissions simultaneously when used in compression ignition (CI) engines. After performing the engine calibration using Design of Experiment (DoE), tests on a roller bench were conducted on a vehicle adapted to be operated with HRG. The results show 7% CO2 reduction using HRG fuel compared to the baseline diesel vehicle while 17% of CO2 benefit compared to the best in class SI car of equivalent size and power. Furthermore, vehicle simulations were used to assess the potential of the GCI vehicle technology when combined with a hybrid electric architecture. From the HEV simulation study, the 2030 CO2 target was reached by using a 48 V 1 kWh battery, P2 architecture, and recalibration the internal combustion engine and after-treatment system (ATS) while fulfilling the expected new EU’s pollutant emission standards.

“…A more optimized combustion chamber design was developed by Chang et al [25] to improve the idle and light load combustion stability of naphtha fuels. The application of low cetane number (CN) naphtha fuels on diesel CI engines were evaluated by Won et al [26] and Chang et al [25] with different bowl and nozzle designs. Diesel CI engines can run with low CN naphtha fuels without compromising the vehicles' drivability, emissions, and power requirements.…”

In this work, the spray and auto-ignition characteristics of light naphtha (LN), primary reference fuels (PRF65, PRF95), Haltermann gasoline (CARB LEVIII, 10vol% ethanol), and a gasoline surrogate were studied in an optically accessible constant volume combustion chamber. An outwardly opening hollow cone piezoelectric gasoline direct injection fuel injector was used. Five ambient temperatures from 650 to 950 K with a 75 K step were selected with a fixed ambient density of 3.5 kg/m 3 , similar to the Spray G density defined by the engine combustion network 2 (ECN). Fuel auto-ignition was achieved with varying ignition delays for the five investigated fuels depending on the selected experimental conditions. Results show that the auto-ignition locations are randomly distributed in the combustion chamber. Differences in ignition delay times among the five fuels are more significant when the ambient temperature is lower than 750 K. When the ambient temperature is lower than 750 K, PRF95 always has the longest ignition delay and LN has the shortest. Ignition delays of the five fuels are almost identical when the ambient temperature exceeds 750 K. Meanwhile, the five fuels have a similar spray front penetration length and spray angles before the occurrence of auto-ignition under all the investigated conditions.
