“…(l/100 km), which is declared by the manufacturer of the GICEV, is determined according to the NEDC. This cycle lasts 1180 s and the vehicle covers a road of 11,007 km during the cycle [97][98]. In this study, analyses of GEHICEVs have been conducted using values between 0 and 30 l/100 km as to be consisted to vehicles on the market.…”

Current Vehicle Air Conditioning (VAC) systems, which are operated by compressors driven by Internal Combustion Engines (ICEs) or batteries, increase the fuel consumption and emissions depending on the thermal load of the vehicle passenger cabin. Since decreasing the thermal load of the vehicle will decrease the fuel consumption and emissions, studies in this area is very important from the economic and environmental aspects. In this study, an Auxiliary Air Conditioning (AAC) system for Internal Combustion Engine Vehicles (ICEVs) or Fuel Cell Vehicles (FCVs) that store Liquid Hydrogen (LH 2) as a powering source has been proposed to make contribution to the works in this significant area. ICEVs were evaluated as Gasoline Equivalent Hydrogen Internal Combustion Engine Vehicles (GEHICEVs) and Diesel Equivalent Hydrogen Internal Combustion Engine Vehicles (DEHICEVs) considering their average fuel consumption rates according to the New European Driving Cycle (NEDC). According to the analyses, approximate hydrogen consumption values have been found that reach 0.7 g/s for GEHICEVs, 1.6 g/s for DEHICEVs, and 0.6 g/s for FCVs with maximum cooling rates of 326 W, 704 W, and 250 W, respectively.

“…In addition, a homogeneous mixture in HCCI results in minimizing Particulate Matter (PM) emissions. However, HCCI suffers from several technical difficulties that require to be solved [14][15]. The main problem associated with HCCI lies in controlling the combustion phasing and the rate of heat release.…”

The European Union (EU) has recently adopted new directives to reduce the level of pollutant emissions from non-road mobile machinery engines. The main scope of project RIVER for which this study is relating is to develop possible solutions to achieve nitrogen-free combustion and zero-carbon emissions in diesel engines. RIVER aims to apply oxy-fuel combustion with Carbon Capture and Storage (CCS) technology to eliminate NOx emissions and to capture and store carbon emissions. As part of this project, a computational fluid dynamic (CFD) analysis has been performed to investigate the effects of oxy-fuel combustion on combustion characteristics and engine operating conditions in a diesel engine under Homogenous Charge Compression Ignition (HCCI) mode. A reduced chemical n-heptane-n-butanol-PAH mechanism which consists of 76 species and 349 reactions has been applied for oxy-fuel HCCI combustion modeling. Different diluent strategies based on the volume fraction of oxygen and a diluent gas has been considered over a wide range of air-fuel equivalence ratios. Variation in the diluent ratio has been achieved by adding different percentages of carbon dioxide for a range from 77 to 83 vol.% in the intake charge. Results show that indicated thermal efficiency (ITE) has reduced from 32.7% to 20.9% as the CO2 concentration has increased from 77% to 83% at low engine loads while it doesn’t bring any remarkable change at high engine loads. It has also found that this technology has brought CO and PM emissions to a very ultra-low level (near zero) while NOx emissions have been completely eliminated.
