The statistical analyze made in this paper shows the significant aspects, values and potential for development and investments in transport sector on national and local levels in Romania, with consideration of their influence also on the environment. The transport is one of the most developed activities developed by humans. It affects everybody and also the environment as a whole. Our country is focusing right now on transport activities, because since 2007, after integration there are increasing preoccupations for import and export activities. Predominantly importing materials and goods needs a lot of transportation to be made. Also people traveling between countries also need transportation and vehicles to do these trips. Many companies have been developed in the last 2 decades in order to meet these requirements of the market. There are no studies to show how far has been gone with this transportation development and which is the trend. The economics is close related to the transport activity or else it would not be done. The environmental impact is also great with high transportation activities, even if there are newer vehicles registered every year. The present paper shows the vehicle registration both in Cluj and on national level for different types of vehicles, especially those which are negatively impacting the environment and the economic activities, the market and society.

RESEARCH OF WEAR CAUSING FACTORS AND LUBRICANT CHARACTERISTICS IN CASE OF BIO-FUEL SUPPLY TO THE AGRICULTURE MACHINE’S ENGINE
Lubricants and fuels are used in over a billion machines. All of them are used in different operating regimes. Because the viscosity and density of engine’s fluids are different in each case, operating conditions are significantly changed. This idea underlines the specific engine operating conditions when performing actual tasks in agriculture. The fuel-lubricant interaction study leads to solutions regarding the wear problem. Experiments show the problems and also the optimal solutions. Agricultural machine lubrication takes part in determining the reliability and durability. Biofuel-adds in commercial fuel is now common practice and an actual task on agricultural engineering is machines life span. Biodiesel may be used alone or in mixtures with other fuels, either fossil diesel or alternative solutions. The content of biodiesel in commercial fuels throughout the European Union is under 15 percent, but it is supposed to increase toward 20 percent. So, we have to analyse the influence that biodiesel has in lubrication and in component wear. In this study were developed experiments concerning the biofuel use and influence on lubricants in various situations, determined by complex analyse of available data from applied research. There were changes in carbon deposits and quality of lubrication. Biodiesel influenced the lubricant composition.

RESEARCH OF THE ENERGETIC POTENTIAL OF FATI
ACIDS FROM OILS AND OTHER SOURCES FOR
MODERN UTILITARY APPLICATIONS
The present research points out, in specific technical concepts and strategies from engineering expertise, the problematic aspects concerning the use of fatty acids as energy source in some cases when it is not indicated and even a bad idea. After analysing thoroughly Gary Yourofsky’s lectures and essays regarding his views on various important topics we have initiated a study concerning fatty acids as sources for energy. Having an expertise in industrial type of oils use we could expand the interdisciplinary study after considering Gary’s ideas in a cross referencing approach with results of Dr. John Mcdougall, Dr. Collin Campbell, Dr. Neal Barnard, Dr. Joel Kahn, Dr. Nick Delgado, Dr. Michael Klapper, Dr. Garth Davis, Dr. Caldwell Esselstyn, Dr. Michael Greger. The fatty acids are some of the most important sources of energy on our planet, especially when they are used as fuel for multiple existing thermal machines. In our laboratory we use oils for Diesel engines as fuel or as an insulator for energy convertors, as well as lubricant or as transmission fluid. By a chemical process of trans-esterification oils are transformed in biodiesel. Link between machinery use of fatty acids and human use as food is important to be considered. In this paper are synthesized some of the data acquired till this moment regarding the energy potential of fatty acids for modern applications. Between food use of oils and fuel for combustion processes, as well as insulator or hydraulic fluid, there is a lot of consideration to be made.

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.

Contributions to experimental research OF technical state of suspension and of its influence upon confort and adherence to the road surface for opel corsa vehicle

 

The experimental work presented in this paper shows some of the achievements during practical testing of the suspension system and wheel train in order to gain information on their influence upon adherence or road contact stability. The experimental tests were conducted in order to point out the influence of suspension springs, tires and dampers on the adherence and road contact between tires and sustaining surface. There were examined the weight axle and suspension efficiency on each wheel of the vehicle during vibration of the testing plates. In the experimental work are also specified the main vehicle components and the suspension test-bed infrastructure in order to gain further more quality and definition of the practical procedure. The opportunity and main significance of testing the suspension quality at different vibration frequencies and for each wheel of the two vehicle’s axles in order to point out adherence level is based on the capacity of test-bed and on the importance of vibration influences in vehicle’s over-all performance.

Contributions to applied research OF kinematic-phenomenological aspects of PISTON-rings for compression ignited engine used in agriculture and automotive industry

 

The present scientific paper synthesizes an applied work on the engineering task of piston-ring displacement modelling and simulation in the case of an internal combustion engine for agricultural application. Piston-rings configuration and displacement, as well as their particular role in the whole assembly, materials, dimensions and lubrication process, in various working cases, are quite significant in influencing the engine’s performance and economy (oil consumption and pollution). In this paper are highlighted the piston-ring displacement modelling and their critical efforts analyse for an agricultural engine, defined on the bases Lombardini tractor engine (510 ccm). The opportunity and importance of modelling the piston-rings movement at different levels and cases in the operational cycle lay on the possibility of highlighting their stresses and predict work expectancy.

The present experimental research points out a complete work of testing the exhaust pipe and after-treatment systems for a modern spark engines with different components, by evaluating the phenomenology and few parameters. There is a fact that the gas exhaust system construction and operation has an influence upon the gas flow and also on the engine behaviour. Testing the exhaust after-treatment systems may generate engineering improvement solutions in order to optimize the engine performance and hydrocarbon economy.

Nowadays in Europe the environmental issues and energy independence are very often priorities on the public and private agenda. The present paper research the issue of practical testing exhaust gas pipe-line and advances the solution of repair and evaluate existing components, with significant changes in dynamic performance and engine environmental impact. By restoring the after-treatment components in their original state the emissions are lowered.
