Computational Fluid Dynamics is used to assess the thermal (heat transfer) performances of an automobile engine considering different grille opening and closing degrees. For this purpose entire vehicle modelled three fundamental aspects are examined, namely, open area air intake grille, position upper lower grilles their shape. The results show that have some influence also on aerodynamic chara...

Real{time systems are de ned as those systems in which the correctness of the system depends not only on the logical result of computation, but also on the time at which the results are produced. Real-time systems span a broad spectrum of complexity from very simple microcontrollers (such as a microprocessor controlling an automobile engine) to highly sophisticated, complex and distributed syst...

This paper reports about practical experience and algorithmic improvements in active isolation of engine induced vibration. The analysed control algorithms are implemented on an experimental setup that resembles the automobile structure of interest. All considered algorithms are of feedforward structure. An important condition of the given application is the availability of a tachometer signal....

The paper presents design and experimental investigation of an electronic system for control the temperature exhaust gases turbocharging air pressure in turbochargers diesel automobile engines. existing problems are faults fuel engine. indicators changes values exact areas turbocharger. presented device is a controller that monitors precisely pressure, which so vital long operation automobile. ...

The development of automobile emission reduction technologies has decreased dramatically the particle concentration in emissions; however, there is a possibility that unexpected harmful chemicals are formed in emissions due to new technologies and fuels. Therefore, we attempted to develop new and efficient toxicity prediction models for the myriad environmental pollutants including those in aut...

Automobile component malfunctions are typical causes of many on-road accidents. Proper fault diagnosis conducted on automobile engines helps to prevent accidents by providing early warnings. The instantaneous angular speed (IAS) method, which uses low-cost sensors, has proved useful in diagnosing combustion-related faults in engines. In this paper, we evaluated various types of faults that occu...

The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO), soot, particulate matter (PM), etc. The use of Dimethyl Ether (DME) biofuel in diesel engines or other c...

This paper used the data of automobile traffic accidents from 2018 to 2020 in Chinese National Automobile Accident In-Depth Investigation System. The prediction features accident severity are innovated. Four that did not participate importance ranking were added: location, form, road information, and collision speed. Eight (engine capacity, hour day, age vehicle, month year, day week, band driv...
