This paper will focus on analysing the air quality on a frequently congested road section in the vicinity of Timisoara, Romania. The placement of the measurement equipment will be made next to a public transport station ...

This paper studies the kinematic parameters of the vehicle occupants in case of a frontal impact between a vehicle and a concrete barrier. The main objective is to determine the head and thorax acceleration of vehicle ...

The continuous rush for development has led the world of automotive engineering to progress that seemed unimaginable just a few years ago. This research paper examined the impact of a topological optimisation of an internal ...

The present paper aims to analyse the possibility to prevent machine failure due to bearing faults, with the use of frequency analysis. The experimental research consisted in mounting a simple mechanical transmission, ...

The biggest problem regarding the safety of occupants during the rear-end collision is the occurrence of “Whiplash” phenomenon, which means that the human head moves backwards in relation to the thorax movement which is ...

The functioning of the engine in a closed loop with lambda sensor and catalyzer makes the excess air factor to be maintained as close as possible to the value 1=1. Based on an own model, the authors realized an analytical ...

The balance between city development, as, for example, an increasing number of working places and emissions control, is a challenge in our days in the urban environment. All new developments in the urban area, either ...

Even though the frontal collisions occur in a much larger percentage than the lateral collisions, the lateral collisions consequences can be much more serious than the frontal collisions. This paper is meant to be a study ...

The present study aims to measure vibrations in machine parts, perform the corresponding spectral analysis and, finally, obtain a diagnosis. The test was performed on a cardan shaft, measuring the vibrations with a uni-axial ...

Diesel, as a fossil fuel, is widely used in industrial and agricultural fields. Added biofuels to fossil fuels affect the performance and combustion characteristics in the internal combustion engines. Ethanol is a renewable ...
