Opis:: The inner atmosphere of a car vehicle became one of the most important environments of human life. Many elements inside of a car cabin are potential sources ofvolatile organic compounds (VOC's) which hazardous effect on human health is proved. To estimate quality of indoor air of a car the qualitative analysis of hydrocarbons is very important considering the fact that some substances (i.e. benzene, acetone and xylene isomers) despite low concentration level characterize toxic and carcinogenic properties. A significant impact on VOC's concentration has vehicle cabin eąuipment and quality of applied materials. The internal sources of the pollution are elements of cabin equipment (textiles, foams, plastic materials), solvents in glues, paints, lacąuers and car cosmetics. The external sources of the pollution are pollutants emitted to environment in gas phase by mobile or static sources. This paper presents the results of the research which aim was qualitative and quantitative analysis of VOC's concentration inside of various classes of car vehicle cabins. The research was done in Emission Research Laboratory of the Division of Motor vehicles and Internal Combustion Engines. The analysis was done according to European standard (EN ISO 16017-1: 2006) on gas chromatograph (Varian 450 GC) eąuipped in capillary column and flame-ionization detector (FID). Keywords: Volatile hydrocarbons, indoor measurements, car vehicle cabin.

Opis:: The description of the scheme and design of the test bench for testing vibration isolators intended for use in the vehicle's cabin suspension. Test bench construction allows to implement a wide range of loadings on vibration isolator of the vehicle cabin, to investigate the impact of the loading's arm changing and to perform analysis of the vibration isolator’s elastic and damping characteristics changing impact on cushioning quality. Variant of the test bench construction modernization, which can allow applying typical exploitation loads, which include vertical and lateral components, is described. We propose a scheme of forced oscillations excitation system on the test bench by cam-eccentric mechanism. It includes a DC motor with stepless frequency regulation and with cams of different shape on its shaft, which affect the contact surface of the test bench's vertical H-beam of a rocker arm. We also propose a scheme of forced oscillations excitation system on the test bench by inertial exciter. It includes a DC motor with stepless frequency regulation with inertial vibration exciter on its shaft, which consists of a mass, placed eccentrically relative to the shaft axis. There are two variants of the test bench scheme – with the forced oscillations excitation device and without it.

Opis:: The effects of additional cavities and air-gaps in the acoustic response of a passenger vehicle are investigated. It is observed that the cabin cavity and the trunk cavity of the passenger vehicle are connected through an aperture in the rear seat. In the trunk cavity of the vehicle, there are two more air-gaps which are designed as countermeasures to trunk lid slam noise. It is established that acoustic modes and acoustic eigenfrequencies of the vehicle are altered through the trunk cavity and its air-gaps. To develop an analytical solution, the actual acoustic cavity is simplified into a rectangular shape. In the analytical solution, the coupling of trunk and cabin cavities is considered. It is shown that the computational analysis results match well with the results of the analytical solution proposed. Further, the resonator effect of air-gaps present in the trunk cavity is examined.
