SOLUTIONS FOR REDUCING THE AIR POLLUTION GENERATED BY VEHICLE
Abstract
Reducing air pollution is a major objective of road transport, the most important consequence of this reduction being the decrease in the number of illnesses and, implicitly, a better quality of human life. To achieve this goal, researchers- efforts have been directed towards reducing the quantities and treating the exhaust gases of vehicles equipped with internal combustion engines. It is important to note that the reduction of environmental pollution must also aim at decreasing the emissions of particles that are not generated by the operation of internal combustion engines. The work aims to reduce the pollution generated by the malfunctioning of the steering systems of motor vehicles. Failures of this type cause additional friction between the tires and the roadway, generating additional amounts of NEE particles. The experiments focused on the detection of these faults during driving, using a Dacia Renault vehicle, a Samsung Galaxy brand mobile phone, type A71, with an accelerometer and iNVH-Bosch software for data processing. The analysis of the results revealed that the symptoms of failure of the steering systems, abnormal shocks and vibrations, can be detected while driving, inside the passenger compartment. The paper highlights the possibility of development of an electronic control system, with a software for vibration analysis, in order to implement a predictive maintenance system. The advantages of equipping vehicles with a system of this type are the early detection of faults and the reduction of environmental pollution.
