Fuel consumption and CO2 emissions of passenger cars over the New Worldwide Harmonized Test Protocol
Dimitris Tsokolis,Stefanos Tsiakmakis,Athanasios Dimaratos,Georgios Fontaras,P. Pistikopoulos,Biagio Ciuffo,Zissis Samaras +6 more
TL;DR: In this article, the effect of WLTP introduction on the reported CO 2 emissions from passenger cars presently measured under the New European Driving Cycle and the corresponding test protocol is assessed.
Journal ArticleDOI
A simulation-based methodology for quantifying European passenger car fleet CO2 emissions
TL;DR: In this paper, the authors proposed a new method for the detailed calculation of the European light duty vehicle fleet CO2 emissions, which could help to overcome such limitations, achieve better results when making CO2 emission projections and better support future policies.
Journal ArticleDOI
Comparative Evaluation of the Effect of Various Technologies on Light-duty Vehicle CO2 Emissions over NEDC and WLTP☆
Athanasios Dimaratos,Dimitris Tsokolis,Georgios Fontaras,Stefanos Tsiakmakis,Biagio Ciuffo,Zissis Samaras +5 more
TL;DR: In this article, the effect of various fuel economy technologies on the certified CO 2 emissions of light duty vehicles is evaluated under two different driving cycles, namely the New European Driving Cycle (NEDC) and the Worldwide harmonized Light duty Test Procedure (WLTP), which is considered closer to real world driving and is going to be the new type approval test in the near future.
Journal ArticleDOI
The difference between reported and real-world CO2 emissions: How much improvement can be expected by WLTP introduction?
Georgios Fontaras,Biagio Ciuffo,Nikiforos Zacharof,Stefanos Tsiakmakis,Alessandro Marotta,Jelica Pavlovic,Konstantinos Anagnostopoulos +6 more
TL;DR: In this paper, a first estimate of the certification-reality gap under the present (2015) conditions is attempted and the impact of the new test procedure is investigated and a detailed simulation matrix was subsequently formulated, taking into account the two tests and expected conditions occurring during real world driving.
Journal ArticleDOI
Performance analysis of a small-scale combined heat and power system using agricultural biomass residues: The SMARt-CHP demonstration project
Dimitrios Mertzis,P. Mitsakis,Stefanos Tsiakmakis,P. Manara,Anastasia Zabaniotou,Zissis Samaras +5 more
TL;DR: In this paper, a small mobile agricultural residue gasification unit for decentralized CHP (combined heat and power) production is designed and constructed within the framework of the SMARt-CHP LIFE+ project.
