Operational stability of a spark ignition engine fuelled by low H2 content synthesis gas
Andraž Kravos, Tine Seljak, Samuel Rodman Oprešnik, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: synthesis gas;spark ignition engines;thermodynamic combustion analysis;knock detection;cycle-to-cycle variations;operational stability;
The paper focuses on the implementation of a comprehensive and robust optimization procedure for a synthesis gas fired four-cylinder, spark ignited, 2.2 L industrial engine used in combined heat and power applications. Innovatively designed workflow is for the first time incorporating also a thoroug ...

Simultaneous particulate matter and nitrogen oxide emission reduction through enhanced charge homogenization in diesel engines
Urban Žvar Baškovič, Rok Vihar, Samuel Rodman Oprešnik, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: compression ignition engine;low temperature combustion;partially premixed combustion;tire pyrolysis oil;engine control;combustion parameters;emissions;
In the presented study, low temperature combustion was established with a direct injection of diesel fuel being a representative of high reactivity fuels and tire pyrolysis oil being a representative of low reactivity fuels. Tire pyrolysis oil was tested as a potential waste derived fuel for low tem ...

Real-World fuel consumption, fuel cost and exhaust emissions of different bus powertrain technologies
Samuel Rodman Oprešnik, Rok Vihar, Tine Seljak, Rok Vihar, Marko Gerbec, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: tehnologije avtobusnih pogonskih sklopov;trenutni plinski in PM10 izpusti;vozni cikel v realnem svetu;bus powertrain technologies;instantaneous gaseous and PM10 mass emissions;real-world driving cycles;
Air quality in urban areas is strongly influenced by exhaust emitted by the public transport fleet. The aim of this study was to analyze benefits in the fuel consumption, fuel costs and exhaust emissions when replacing baseline diesel fueled EURO III city buses by the compressed natural gas (CNG)-fu ...

RCCI combustion with renewable fuel mix - Tailoring operating parameters to minimize exhaust emissions
Urban Žvar Baškovič, Rok Vihar, Samuel Rodman Oprešnik, Tine Seljak, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: low temperature combustion;reactivity controlled compression ignition;waste-based fuels;hydrotreated vegetable oil;low swept volume;internal combustion engines;emissions;
This article demonstrates a feasible approach towards minimizing negative impact of combustion, which comprises low net carbon emissions operation of internal combustion engines while achieving ultra-low engine-out exhaust emissions. Ultra-low emission operation was achieved by combining Reactivity ...

RDE-based assessment of a factory bi-fuel CNG/gasoline light-duty vehicle
Davor Rašić, Samuel Rodman Oprešnik, Tine Seljak, Rok Vihar, Urban Žvar Baškovič, Tomaž Wechtersbach, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: osebna vozila;komprimiran zemeljski plin;bencinsko gorivo;Real Driving Emissions RDE;Portable Emission Measurement System PEMS;light-duty vehicle;CNG;gasoline;
On-road exhaust emissions of a Euro 5 factory bi-fuel CNG/gasoline light-duty vehicle equipped with the TWC were assessed considering the Real Driving Emissions (RDE) guidelines. The vehicle was equipped with a Portable Emission Measurement System (PEMS) that enabled the measurement of THC, CO, NOx, ...

Complementing syngas with natural gas in spark ignition engines for power production
Carlo Caligiuri, Urban Žvar Baškovič, Massimiliano Renzi, Tine Seljak, Samuel Rodman Oprešnik, Marco Baratieri, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: spark ignition engines;renewable fuels;combustion;syngas;natural gas;
Power generation units based on the bio-syngas system face two main challenges due to (i) the possible temporary shortage of primary sources and (ii) the engine power derating associated with the use of low-energy density fuels in combustion engines. In both cases, an external input fuel is provided ...
