“…Fuel-burner systems are faster in reaching light-off than electrical ones since they can deliver significantly more power (10 to 20 kW) but are more complex [22]. Bhaskar et al [23] tested the influence of air supply, together with an electrically heated precatalyst, both placed before the main catalytic converter, on the final conversion efficiency. The pre-catalyst was heated using a band-type resistance heater (RHCC).…”

Despite the current boost in the use of electric vehicles to reduce the automotive sector’s footprint, combustion vehicles are and will be present in our cities in both the immediate and long term. In this sense, catalytic converters, which are exhaust gas post-treatment systems for vehicle emission control, are critical for complying with increasingly stringent environmental regulations. This work proposes a systematic review to identify the most relevant knowledge regarding the parameters (materials, geometries, and engine conditions), conditions (cold start, oxygen storage, and deactivation), and mathematical models to consider in the design of catalytic converters. The Scopus database contains 283 records related to this review’s objective. After applying the inclusion and exclusion criteria, 65 reports were retrieved for evaluation. A table was created to present the results and prepare this manuscript. The evaluation revealed that the following topics were active: the study of non-noble catalyst materials, as well as new substrate materials and geometries, for designing more compact and cost-effective catalytic converters; the development of strategies to improve conversion during cold starts; and the development of accurate and fast estimation models.

“…In general, the results obtained allow for the conclusion that, on a global scale, there is possible substantial progress in the reduction in pollutant emissions from automotive combustion engines, especially during engine warm-up. Therefore, further works towards the improvement of internal combustion engines are necessary, e.g., on the accel-eration of the heating of catalytic exhaust after-treatment systems and on the long-term maintenance of the thermal status of the engine after stopping with the use of thermal accumulators [29][30][31][32].…”

Influence of the Thermal State of Vehicle Combustion Engines on the Results of the National Inventory of Pollutant Emissions

et al. 2021

The article presents the results of studies on the influence of the thermal state of vehicle combustion engines on pollutant emissions. This influence was analyzed based on data from Poland’s inventory of pollutant emissions for the years 1990–2017. The results show that during engine warm-up, carbon monoxide emission constitutes the largest share (up to 50%) in the national annual total emission. Volatile organic compounds are next in the ranking, whereas the share of nitrogen oxides is the lowest (less than 5%). Under the model traffic conditions, close to those in Poland’s cities in winter, simulation tests regarding additional pollutant emissions from passenger cars during engine warm-up were also carried out. As a result of the cold-start emissive behavior of internal combustion engines, emissions of carbon monoxide and volatile organic compounds showed a considerably greater impact on national pollutant emission, as compared to carbon dioxide, nitrogen oxides and particulate matter. This is particularly evident for the results of the inventory of pollutant emissions from road transport.
