The aim of the tests and measurements presented in this thesis was to analyze and study both the statutory and non-statutory pollutant emissions of four vehicles for different driving cycles. Passenger gasoline-powered vehicles, compliant with EURO 1-4 emission standards, were compared with each other regarding pollutant emissions under real-world conditions. The effect on the rate of increase in engine temperature and exhaust gas emissions of different ambient temperatures was studied in tests conducted not only in summer but also in winter. It should be noted that a greater effect of ambient temperatures was observed on the rate of increase in the temperature of the lubricant and the coolant than on the operating temperature of the catalyst until it reaches its maximum efficiency. Five different urban driving cycles were developed and used, including free-flow driving and congested driving. Exhaust emissions under real driving conditions in an urban environment were measured and compared with the relevant EU legislation using the FTIR (Fourier Transform Infra-Red) emission measurement system installed in the vehicles. Different driving parameters such as speed, fuel consumption and air/fuel ratio, coolant, lubricant and exhaust gas temperatures were recorded and analysed for all the above driving cycles. The temperature profile indicating the required time period for maximum catalyst performance and the effect of cold start on fuel consumption were investigated and evaluated. In addition to the CO 2 , CO, HC and NOx emissions, the emissions of volatile organic compounds (VOC) were also analyzed and the ozone formation potential (OFP) was calculated on major urban roads and intersections for different cars. Various greenhouse gases, such as CO 2 , N 2 O and consequently the global warming potential (GWP) and CH 4 emissions, were also calculated as a function of the engine warm-up rate and driving cycles. The results had a reasonable repeatability in most pollutant emissions and provided a better understanding of the greenhouse gas emissions associated with traffic congestion in urban areas and will contribute to the control of climate change. This research analyzed the factors that affect exhaust emissions in the city and will be useful for better traffic management and the reduction of pollutant emissions. The research data can be used to predict pollutant emissions in urban areas.

Dimitrios Savvidis, "Modern braking systems and safety", Gkiourda Publishing House, (first edition), ISBN 960-630-763-8, Thessaloniki, Greece, November 2006.
This book contains information on vehicle braking systems and the various components used today, while the operating principle of the ABS system is also studied, with emphasis on the various variants on the market. The operation of a vehicle's wheel slip control system is analyzed and described in detail, while the effect of the braking system's characteristics on the vehicle's road behavior is studied. Sections such as electric and hydraulic retarders are covered, while finally, a reference is made to the type approval process of a braking system and the legislation that must cover it, from the initial design stage to its installation in modern vehicles.

This paper evaluates the methodology proposed by the European Commission for the monitoring and certification of CO2 emissions and fuel consumption of heavy-duty vehicles (lorries and buses) in Europe. The new methodology is based on a combination of component tests and computer simulation of the fuel consumption of the vehicles. Measurements were carried out on two vehicles, a 40t Euro VI long-haul tractor and an 18t Euro V two-axle truck. The measurements were carried out both on a brake dynamometer and in real road conditions. A simulation software was used to simulate the tests. The ability of the software to record vehicle performance and fuel consumption was evaluated based on the measured data. The simulation results are very close to those of the dynamometer tests while the final simulated fuel consumption value deviates by approximately ±2-4% compared to the measured values. During the tests carried out on the road, the final fuel consumption showed a deviation of ±3.5% from the simulation and it is concluded that a future vehicle certification system can be based on this approach and achieve high representativeness, compared to

Pierre Bonnel, Adolfo Perujo, Alessio Provenza, Pablo Mendoza Villafuerte in collaboration with Dimitriοs Savvidis, "Non Road Engines Conformity Testing Based on PEMS", JRC Scientific and Policy Reports, Report EUR 26438 EN, ISBN 978-92-79- 35090-0, doi: 10.2789/18679, Luxembourg: Publications Office of the European Union, 2013
With the introduction of the EURO V standards for heavy-duty engines, European exhaust emission legislation requires verification of the compliance of heavy-duty engines with the applicable emission certification standards: these provisions are defined as "In Service Conformity (ISC)". It was considered impractical and costly to adopt an ISC system for heavy-duty vehicles that required the removal of the engine from the vehicles for testing emissions against the legislative limits. Therefore, it was proposed to develop a protocol for checking the in-service conformity of heavy-duty vehicles based on the use of Portable Emission Measurement Systems (PEMS). As a result, the PEMS-based ISC test was introduced in the EURO V and EURO VI standards. The corresponding administrative and technical provisions were laid down in European Regulations 582/2011 and 64/2012. The above path was also followed for engines of non-road mobile machinery (Non Road Mobile Machinery - NRMM): preliminary research activities were studied and confirmed the applicability of the methods developed for heavy-duty engines with minor modifications. The basis for the introduction of ISC provisions based on the PEMS approach in the European legislation for the type-approval of NRMM has been confirmed in several texts. The "NRMM PEMS" pilot project was launched to facilitate the introduction of the use of PEMS as a tool for ISC in the European legislation on NRMM emissions. This was to be achieved by improving technical procedures (e.g. available from the heavy-duty vehicle programme) and raising awareness of the various stakeholders about PEMS as a new legislative tool.

Ioakimidis, "Engine emissions measurements from passenger cars at two different locations within the metropolitan area of Antwerp in Belgium and further statistical analysis", Internal Combustion Engines: Performance, Fuel Economy and Emissions, IMechE Combustion Engines and Fuels Group Conference, London, England, 27-28 November 2013: 67-77, ISBN: 9781782421849. Woodhead Publishing.
The paper presents real-world measurements of exhaust emissions from passenger car engines (petrol and diesel) at two different locations on the campus of the University of Antwerp within the metropolitan area of Antwerp in Belgium. Most of the vehicles were measured under different operating conditions (warm or cold engine) and under different weather conditions (different ambient temperature, humidity, etc.). Very low temperatures, snowy or rainy weather conditions and sunny days were included and taken into account in the measurements and the differences in exhaust emissions are presented in this paper.

J. Fuels Lubs. 3(1): 133-148, 2010. (SAE Technical Paper Series 2010-01-0477. SAE Book SP-2292: Advances in Alternative Energy and Fuels for the Transportation Sector, 2010. ISBN: 978-0-7680- 3426-4. SAE World Congress, Detroit, USA).
This work investigated three of the greenhouse gases emitted by road transport using a EURO 2 petrol-powered passenger car: Specifically, CO 2 , N 2 O and CH 4 emissions were evaluated as a function of the vehicle’s cold start and ambient temperature. A real-world test cycle has been developed in Leeds and is referred to as LU-BS, which has a free-flow urban driving pattern. The test vehicle was driven on the same route by the same driver on different days with different ambient temperatures. All tests started with a cold start. An FTIR (Fourier Transform Infra-Red) exhaust emission measurement system with an accuracy of 0.5 Hz was installed inside the vehicle for the measurements. This emission measurement system was calibrated to a standard CVS measurement system and excellent accuracy was found between the CO 2 measurements and the CVS (Constant Volume Sampling) results. N 2 O and CH 4 were calibrated with calibration gas cylinders. The effect of ambient temperature on greenhouse gases and global warming potential (GWP) were also evaluated in this work. The research helped to better understand the impact of traffic on greenhouse gases in an urban area and will contribute to the control of climate change.
