Driving cycle simulation of hybrid passenger cars powered with hydrogen engine

Original language description

The hydrogen combustion engine (H2ICE) provides an available and mature solution to the demand for carbon neutral trans- portation. H2ICE doesn’t produce (relevant) on-site CO2 emissions and the emitted amount of the principal pollutant (NOx) can be minimized to near zero levels using correct engine control and aftertreatment. The research objective is to evaluate the per- formance of H2ICE in passenger cars, accounting for current powertrain trends (downsizing, turbocharging and hybridization). Experimental data from a single cylinder engine are used to construct an equivalent virtual 4-cylinder 1.5l engine, which is in- corporated into a vehicle model. Mild hybrid vehicles, representing four segments, are then investigated through driving cycle simulations. The subsequent virtual engine maintains very high efficiency and low NOx emissions throughout majority of its operating range, achieving peak power of 53 kW/l @4000 RPM. The predicted hydrogen consumption for a C segment vehicle in WLTC is 1.1 kgH2/100 km (4 l/100 km of gasoline equivalent), the NOx emissions are kept well below the EURO6 limit without the use of any aftertreatment (0.02 g/km) and the CO2 emissions induced by lubricant-burning amount to 0.2 g/km. With the consid- ered storage solution, the vehicle attains a range of 480 km. The results indicate the potential of H2ICE to decarbonize transportation and to further decrease vehicle fuel (energy) consump- tion while maintaining ultra-low pollutant emissions and an acceptable range.
