EXTENSION OF THE RANGE OF A VEHICLE EQUIPPED WITH A DUAL-FUEL HYDROGEN DIESEL ENGINE BY REPLACING HYDROGEN WITH NATURAL GAS

Popis výsledku v původním jazyce

The passenger car equipped with a dual-fuel hydrogen diesel engine shows the way how to fulfil the future requirement of regulations for CO2 tail pipe emissions of the internal combustion engine. One of the disadvantages of hydrogen vehicles is the lack of hydrogen filling stations. The dual-fuel hydrogen diesel engine can operate with diesel fuel only, however the CO2 tail pipe emissions are not reduced. Further possibility, how to extend the range is a substitution of hydrogen by natural gas, because the natural gas has lower carbon content than diesel oil and natural gas infrastructure is more developed than hydrogen one. This work deals with the substitution of hydrogen with natural gas in the case of a single cylinder research engine, which is partially optimized for diesel-hydrogen operation. The emission and combustion parameters are assessed and compared. The needed data are extrapolated into full-size four-cylinder engine, which is consequently used in the simulation of vehicle drive in GT-Suite. The main results of the simulation are CO2 tail pipe emissions of passenger cars in NEDC and WLTC cycles for pure diesel, diesel-hydrogen, and diesel-natural gas operation.
