Experimental researches of the operational problems concerning the power supply system for the ACID battery from Dacia solenza

 

The present paper express in available technical terms and means of an experimental research concerning problematic aspects of the power supply system from Dacia Solenza 1.4 MPI vehicle in relation with liquid acid accumulator on board.

After cold starts of the internal combustion engine some unusual engine speed fluctuations occur which destabilize the proper operation for the first minutes in cold running of the vehicle.

The worst case scenario is when engine stops suddenly in the middle of a street junction without any previous major signs and as a bonus without any possibility to restart immediately. Analysing the power supply system and differential potential allows the researcher to gain some significant insight in the process and to develop important knowledge (as know-how) and arguments in solving the problem once and for all.

The development of present research aims toward the goal of pointing out the symptoms and problematic aspects related to the power supply and management systems on vehicle Dacia Solenza.

31-54 STUDII ȘI CERCETĂRI PRIVITOARE LA VALIDAREA METODELOR ŞI ASIGURAREA CALITĂŢII REZULTATELOR ÎN LABORATORUL DE ÎNCERCĂRI PENTRU ULEIURILE MINERALE ELECTROIZOLANTE

Studies and researches concerning

the methods validation and data

quality check IN TESTing laboratory

for INSULATING mineral oils

 

This applied technical paper shows the strict procedures and specific operation in specialized laboratory for physical-chemical studies, in order to ensure a proper validation method and data quality checking. Specialized authorities on national and international levels are verifying and control the proper functionality of research certified laboratories. Also beneficiaries and consumers are interested in getting all the precise data in the physical-chemical measurements both in heavy and food industry. In this situation the present scientific article makes a presentation of operating methodology and specific aspects which define the work and quality checks in this field.

20-41 FOLOSIREA DEŞEURILOR INDUSTRIALE ÎN MATERIALE DE CONSTRUCŢII

USING INDUSTRIAL WASTES IN BUILDING MATERIALS
Using industrial waste (especially those of organic nature) are a
success for both construction and environment. In previous experiments
rubber waste does not undergo thermal or chemical transformations, only a
simple shredding process. Thus, the shredded rubber is inserted in the
concrete mixture, partly replacing the aggregate. By means of this recycling
process, a major objective for sustainable development is confirmed –
improving environmental quality.
