the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

The vehicle emissions tests, which are performed using the Portable Emissions Measurement Systems (PEMS), indicate that diesel cars produce several times more NOx on road than during certification realised according to methodology New European Driving Cycle (NEDC). This fact initiated infamous "dieselgate" affair. It is a well-known reality current emission limits very strict and therefore seri...

Driving cycles are used for certification, for comparison of vehicles, and to an increasing extent as an engineering tool in vehicle design. A situation with only a few fixed driving cycles to use would then lead to the risk that a test or design would be tailored to details in the driving cycle instead of being representative. Due to this, and due to the increased use in the development proces...

The European Union is aiming at increasing the market share of biofuels in order to improve the security ofsupply of transport fuel and to reduce CO2 emissions. The target is to reach a 10% of fuels from renewablesources on energy basis in the transport sector by 2020 and biofuels represent one of the most importantoptions. Bioethanol and biodiesel represent the only biofuels cu...

This paper focuses on light duty of china 6 with the same emission control technology. three vehicles, different engine displacements, were selected to study and fuel consumption characteristics under test cycles NEDC, WLTC CLTC. The results show that emissions CO, THC NOx cycle are minimum, compared NEDC CLTC circulation. decrease displacement, difference CO increases among cycles, which shows...

Through the fuel consumption test of several listed vehicles in China, basic results cold start under CLTC-P cycle, condition air conditioning on, and off are measured. At same time, differences between NEDC cycle China's certification compared, combined The higher than those procedures Chinese more line with actual driving situation China.

In this paper, an economy-oriented car-following control (EOCFC) strategy is proposed for electric vehicles in scenarios. Specifically, a controller based on model predictive (MPC) developed to optimize the host vehicle’s speed better energy economy while ensuring good performance and ride comfort. The consumption accurately quantified form of demand power, which incorporated cost function opti...

This paper aims to design thermal dummy cells (TDCs) that can be used in the development of lithium-ion battery management systems. Based on physical property and geometry real 18,650 cylindrical cells, a three-dimensional model TDCs was designed, it is numerically simulate performance TDCs. Simulations show TDC mimic temperature change surface cell both at static dynamic current load. Experime...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...
