“…In the tests the measurements of toxic compounds emission were performed and, for comparison, signals from an on-board diagnostic system were also registered (standard SAE J1850), e.g., engine speed, load, vehicle speed and intake air temperature [8][9][10][11][12]. Some of these signals served to specify the time density maps presenting the share of the operating time of a vehicle in the real operation.…”

In order to measure the concentration of toxic compounds a mobile analyzer for toxic tests SEMTECH DS by SENSORS Inc. was used. In the study the results of the vehicle emission tests in the road conditions were presented, as this was the only way to obtain the information on real vehicle emissions. They include information on the emissivity of the vehicles in operation and deal with the real conditions of the vehicle motion. Reliable measurement results were obtained, which were verified in simulated conditions on a chassis test bed. The obtained data were used to specify the dependence characteristics for the influence of the dynamic engine properties on the harmful compound emissions. The obtained data enabled one to define the vehicle emission factor, which can be used to classify fleets of vehicles in relation to toxic compounds emissions that differ e.g. in production data, i.e. limits of exhaust emissions, mileage of vehicles or operation conditions.

“…Born fifty year ago, the theory of vehicular control deals with system's optimization for streamlining the driving style. One of the most popular application concern the measurement and control of emission relevant parameters of internal-combustion engine in road car, bikes and trucks [1], [2] driving behavior studies [3], and fault diagnosis [4]. This has led the auto manufactures to directly install on board the vehicle a complex measurement system for self-diagnostic and reporting capability (OBD) according to the Society Automotive Engine (SAE) Standards [5],…”

The main purpose of this work is to develop a data acquisition platform prototype for automotive telemetry applications such as driving style analysis, fleet management and fault detection. Measurements are gathered from On-Board Diagnostics (OBD) sensors, Global Positioning System (GPS) and an Inertial Measurement Unit. (IMU) logged on the onboard device for remote backup. The data obtained could be used to driver behavior studies, to define insurance premium, to engage user in saving fuel and money and to correlate faults on car with the driving style.

“…An important thing however is the impact of diesel engines on the natural environment. According to research published in [1][2][3][4][5] the exhaust gas from diesel engines is very harmful to human health. The results of research conducted by IARC (International Agency for Research on Cancer), a member of WHO (World Health Organization), in the report published in June 2012 qualified diesel exhaust gases to a group of carcinogenic factors.…”

In urban areas, the most frequently operated type of vehicles are the on-road vehicles such as passenger vehicles and city buses. In many agglomerations (Berlin, Munich) zones have been introduced where only exhaust emissioncompliant vehicles are permitted. If they fail to meet the set standards for a given zone an appropriate charge is incurred. We should remember, however, that in city centers non-road vehicles are also used for specific work such as the maintenance of green areas. Unfortunately, these types of vehicles are fitted with engines that are technologically obsolete in comparison to modern on-road vehicles. Hence, the exhaust emissions from the non-road vehicles are far greater as compared to regular vehicles, which is confirmed by much more liberal emission standards for this group. This paper discusses this issue in detail and presents the results of the exhaust emission tests carried out under actual operating conditions (maintenance of green areas). In order to better depict the situation the results were compared with the exhaust emissions of passenger vehicles also obtained under actual traffic conditions.
