The finite element modeling methods of a passenger car exhaust system’s flexible parts are introduced. A finite element (FE) model of the exhaust system is established with the finite element software and modal analysis of the FE Model is carried out. Through changing both automotive exhaust hangers’ Z direction of stiffness and bellows’ each direction of stiffness, the data of natural frequencies and vibrating modes of the exhaust system were obtained respectively. Comparing and analyzing the results indicates how the stiffness of exhaust hangers and bellows influences the modal of passenger cars’ exhaust system.

Vehicle Motion

In terms of simulation research, it is important to simulate real conditions as precisely as possible. This type of approach makes it possible to minimize the error in the obtained results. The dynamics of acceleration is one of the most important factors having a direct impact on fuel consumption and exhaust emissions from vehicles. The work was carried out with the use of PTV Vissim microscopic vehicle motion simulation software. The considerations were carried out on theoretical acceleration profiles with different dynamics values and the actual character of acceleration, recorded during road tests. The simulations were carried out for a car powered by spark-ignition and compression-ignition engines. The research showed that the calibration of the acceleration character of the vehicle in simulation tests may result in significant differences in obtained results of exhaust emissions.

In this paper, particulate numbers were measured from an in-service PASSAT passenger car fueled with blends of biodiesel and China Phase IV diesel in different ratios using EEPS-3090 (Engine Exhaust Particle Sizer) Spectrometer. Fuel blends composited of 5%, 10%, 20%, 50% and 100% biodiesel were used and nominated as B5, B10, B20, B50 and B100, respectively. A total average speed of 31 km/h was observed, and for urban arterial roads and suburban freeways, average speed displayed an individual magnitude of 19.7km/h and 72km/h. After using blends of biodiesel/diesel, particulate mass emission factors displayed different reduction percentages. For particulate number emission factors, increasing trend was observed on city arterial roads and a declining trend for sub streets in urban and suburban areas. Particulate numbers emission exhibited normal distribution on suburban highways, while bi-normal distribution was revealed for other types of roads. With higher biodiesel/diesel blending ratios, particulate number in accumulated mode from passenger car exhaust showed lower value but higher value for nuclei mode, and the center size for peak particulate number emissions moved towards smaller scales.
