Inspection and Maintenance of In-Use Motor Vehicles – Mitigating Environmental impact

International Centre for Automotive Technology-Vijayanta Ahuja, Aditya Gautam
  • Technical Paper
  • 2019-28-2427
Published 2019-11-21 by SAE International in United States
The existing rule no. 62 of CMVR, 1989 applies to various commercial vehicles and yet is unable to provide a promising template to have a concise format which will cover all the motor vehicles and their different components with more precise equipment plus virtual testing along with proper management of time during the bulk inspection of all the vehicles. This paper will include all the technicalities and the different course of actions which must be taken into account for the proper implementation of the desired regulations on the designated concern. The idea behind this paper is to have a compact procedural document for the periodical inspection and maintenance of all the motor vehicles running on the Indian Roads that adhere to the basic safety concerns of other on-road vehicles, the pedestrians and the surroundings. Concluding the fact that there are various aspects of environmental degradation henceforth we start by picking one of the hazards trying to execute a method to resolve every respective issue on a micro level, thus eliminating maximum threats onto the environment.…

Experimental Analysis of Gasoline Direct Injector Tip Wetting

SAE International Journal of Engines

Technical University of Munich, Germany-Fabian Backes, Sebastian Blochum, Martin Härtl, Georg Wachtmeister
  • Journal Article
  • 03-13-01-0006
Published 2019-10-14 by SAE International in United States
At gasoline direct injection, light-duty engines operated with homogeneous, stoichiometric combustion mode, particulate emissions are mainly formed in diffusion flames that result from prior fuel wall wetting. Besides the piston, liner, and intake valves, the injector tip acts as a main particulate source when fuel is adhered to it during an injection. Hence, this injector tip fuel wetting process and influences on this process need to be analyzed and understood to reduce engine-out particulate emissions. The present work analyzes the injector tip wetting process in an experimental way with a high-speed and high-resolution measurement system at an optically accessible pressure chamber. The performed measurements reveal that injector tip wetting can occur during the complete injection event by different mechanisms. Large spray cone angles at start and at end of injection or distortions of the spray result in direct contact of the fuel spray with the step-hole wall. Additionally, fuel accumulates during an injection in the step-hole volume and discharges onto the injector tip surface subsequently. Furthermore, a poor primary breakup at end of injection can…
