Abstract
In the article, emphasis made on determining the start operation time of catalytic converter in the open storage car conditions. In this regard, experiments made on author’s experimental setup, quantity of which provides a confidence probability 0,95. Results of experiments allow us to determine the dependences of the warm-up time changes of catalytic converters when the ambient temperature changes from +1°С to -30°С. The compliance with current regulatory requirements for content of CO and CH in engine exhaust provided.
Highlights
The modern three-component automobile catalytic converters are the most important and the most common devices in exhaust cleaning system of internal combustion engines in passengers cars
This paper presents experimental studies and their results to determine the influence of ambient air temperature on warm-up time of catalytic converter in the open storage car conditions
It is necessary to agree with the studies that the amount of carbon monoxide (CO) and CH emissions increases with a decrease in engine temperature [17]
Summary
The modern three-component automobile catalytic converters are the most important and the most common devices in exhaust cleaning system of internal combustion engines in passengers cars. Under low temperatures influence the temperature mode of automobile catalytic converters is changes It explained by increasing heat transfer from surface of the unit to environment. In this regard, the catalytic converters warm-up time is increasing after start and the period of their cooling after stopping is decreasing. The heating time to efficient temperature of catalytic converter depends on different factors, among which the ambient temperature has a significant influence [2]. In this regard, the task of establishing the dependences of the warm-up time changes of catalytic converters in the open storage car conditions becomes relevant
