- W1565682711 abstract "There is a scarcity of data on which decisions can be based regarding the limitation of idling during standstill periods. There is also reason to believe that the significance of engine management during standstill may vary between different propulsion systems and technical standards etc, which will increase the need for a decision base. The need for data that describe exhaust emissions during crawling speed is particularly great in the case of tunnels. Ventilation plants in tunnels are designed on the basis of relationships between emissions and mean speed. Up till now, for speeds below 30 km/h, these relationships have not been satisfactorily based on measured data. The primary objective has been to fill the gaps in knowledge by exhaust measurements. The methodology has comprised a survey of the literature, measurements and analyses. Different objectives result in different limiting times for idling during standstill periods. For the vehicle fleet as a whole, different limits have been estimated for different objectives: for private economy, 12 seconds; for macro economy overall, 23 seconds; for energy policy, 12 seconds, and for air quality, 36 seconds. There are also time limits per compound, per technical standard and per vehicle type. The time for diesel is shorter than for petrol engine. According to measurements, emission of oxides of nitrogen (NOx) at crawling speed varies over the range -51 and 171% for different engine types when speed drops from 25 to 10 km/h. There are considerable differences in the speed dependence of fuel consumption both between and within studies. The relationships which could be estimated for particulate emissions do not, in any one case, indicate an increase in emission as speed drops from 25 km/h." @default.
