solve the problems of this area, specialists need both knowledge of the
mathematical, statistical, legal, psychological and social. In order for the
investing activities to be conducted under conditions of maximum efficiency, all
factors which contribute to its realization, must take responsibility for conducting
the activities on schedule. Delivering the construction on due term should be a
basic requirement in the good development of the investment program. During

30-76 TASARE FOARTE REDUSĂ A SOLULUI GRANULAR LA SĂPAREA CU TBM A METROULUI BUCUREȘTI

VERY LOW GROUND SETTLEMENT IN TBM TUNNELLING IN
GRANULAR SOIL AT THE BUCHAREST METRO LINE 4
The second stage of the Bucharest Metro extension started with the metro
tunnel excavation presented in this paper, the M4 line. Tunnels in soft ground
usually imply drilling through sub-surface un-lithified deposits, namely
cohesive/non-cohesive/mixed soils that involve soft ground tunneling conditions
where the tunnel is driven using a closed shield as temporary ground support. This
must be followed by immediate involvement of tunnel lining due to considerable
potential of ground movement during excavation, realized using a high
mechanization level of the process. The Bucharest soil grain size distribution and
the rest of the soil geotechnical parameters was the main factor to deal with. The
water table also played a major role in determining the TBM type used, presenting
further influences on the stability of the excavation face, with the option of
dewatering the drilling site soil enhancing the TBM circumstances.
The chosen EPB type of TBM handled the geological variations that
occurred at the excavation face (e.g. voids) due to the non-compressive medium
which fills the working chamber at the TBM front and responds instantly and
efficiently at the combined activity of hydraulic jacks thrust pressure; advance
speed; cutter head torque and revolution speed; mucking screw speed which were
controlled via a complex software and proper manning to set a constant value to the
drilling head and TBM shield to achieve the smoothest and fastest advance of the
boring machine. Using a soil conditioner that presented an up-graded formula
rendered to the excavated soil considerably improved parameters. Moreover, the
high degree of mechanization and automation of the excavation activity with TBM
has decreased the high level of soil settlement and excavation face failure risk,
resulting a very low ground settlement value for the project.

Lubricating system from any engine plays an significant role in
generating all of its dynamic performances. Fuel economy and energetic
performances from all compression ignition engines correlate with the working
degree of its lubricating system. The present work studies the mathematical
models of important phenomena from lubricating process. Compression ignition
engine lubrication process has a considerable part in influencing all sequences
of the working cycle and the components life duration. Some phenomena that
influence the lubricating process have a significant role in the engine durability
and consequently on pollution level. Environmental problem and engine’s
working time are significant problems for everyone in the present days. Human
life style has a specific relation with the ambient and modern engines. The
present article studies and outlines the influence of fuel type and engine’s
speed upon the compression ignition engine power losses, due to the
lubrication process through simulation and modeling. It is obvious that there are
very important factors which highly influence the quality of the lubricating
process and thus of the engine’s losses. In this study are presented the
variations and graphs of some important factors that are influenced by the

THE STUDY TROUGH MODELING OF AFTER-TREATMENT
SYSTEM FOR EXHAUST GASES FROM INTERNAL
COMBUSTION ENGINES
The present work shows a detailed analysis of gases after-treatment
systems for modern spark engines with different components installed, by
generating a simulation research of the working phenomenology and
parameters. It outlines the specific field of gas after-treatment methods (with
modern catalytic components) developed for spark ignited engines, specifically
the energy and economy improving possibilities through simulation of the final
evacuation process of gases. There is considered that the gas evacuation and
exhaust system architecture besides the catalytic converter have a major
influence upon the phenomena of gas flow and also on the engine economy
and pollution. Modeling and simulating the after-treatment systems on spark
ignited engines may lead to a multitude of engineering acts and improvement
strategies in order to optimize the environmental performance and fuel
economy, while the engine dynamic performance will be accurately managed.
Today in European Union the specific regulations in antipollution domain and oil
independence in relation with the Middle East are more often discussed, being
high priorities on the institutional and executional panel. The present article
outlines the issue of modeling/simulating exhaust engine systems and
improving the existing components but with significant changes which must
comply with the law requirements of reduced pollution and low consumption.

The research paper outlines an experimental evaluation of the parameters
related to fuel consumption, engine speed, vehicle speed and environmental
temperature in different gear ratios and accelerator pedal positions, with sport
utility vehicle Peugeot 4007 during the urban driving process. There isn’t an
explicit study concerning the consumption and performance in urban driving
situation of the Peugeot 4007. There are many SUVs on the roads of our country,
but there should also be an interest concerning their fuel economy and
environmental impact. The engine and environment temperature, besides the
gear ratio and accelerator pedal position have a significant influence on the
engine’s economy and pollution. In the present paper it is studied the fuel
consumption of the engine when driving the Peugeot 4007 SUV in order to outline
the relation between the gear ratio, vehicle speed and fuel economy. The
collected data is accurately evaluated and observed.

30-45 CERCETAREA PARAMETRILOR SISTEMULUI DE ALIMENTARE PRIN INJECȚIE A MOTORULUI DE LA AUTOMOBILUL BMW 320D

RESEARCH OF FUEL INJECTION SYSTEM
PARAMETERS FOR THE ENGINE OF BMW 320D
The present article makes an analyze through experimental research of
the parameters obtained from practical measurements related to fuel injection
supply, consumption, operating regime and engine speed, in different situations
and accelerator positions, with sport oriented vehicle of the type BMW series 3
during the operating process. There aren’t such explicitly developed studies
concerning the injection parameters of the E90 engine model of BMW 320d on the
national level. It is known that there are many such vehicles registered in our
country, there being a strong will to know their performances and operational status.
The injection and combustion besides the supercharging have a major influence
upon the engine’s dynamic performances, fuel economy and pollution. Testing and
studying the injection and air-fuel supply systems on BMW diesel engines may offer
engineering solutions and optimizing ideas in order to improve their environmental
impact and fuel economy, while the engine dynamic behavior will be little affected. In
this work it is developed a program for testing such a dynamic engine and for
collecting the injection and other systems parameters in order to facilitate their
operational understanding. The data is managed and accurately inspected and
interpreted.

30-41 STRATEGII ALTERNATIVE DE TRANSPORT BAZATE PE TEHNOLOGII AVANSATE

ALTERNATIVE TRANSPORTATION STRATEGIES
BASED ON ADVANCED TECHNOLOGIES
Current systems of transport follow a transition period, regarding the
main sources of propulsive, but also about the movement principle. This
transition is imposed by the requirements of the population mobility acute
increasingly, travel times smaller, reducing the quantities of fossil fuels, the
need to reduce the level of pollution from transport, etc. Nowadays are currently
already used hybrid, hydrogen, electric cars and electromagnetic trains, but
they all require by the primary resource a kind of conventional energy, so the
desired effects are obtained at a reduced level. Thus, following the various
investigations, it was achieved the possibility of build some transport systems
concepts and prototypes, which to use as energy for propulsion, the
unconventional, free, easy to obtain and inexhaustible energy.

30-38 ZECI DE MII DE VAGOANE ȘI LOCOMOTIVE C.F.R., DISPĂRUTE

Nu ştim în ce măsură sunt, sau nu, reale cele prezentate în textul pe care vi-l supunem atenţiei, dar, pentru „organele abilitate”,
investigaţia ar trebui să se îndrepte spre liniile de cale ferată
„privatizate” – a se citi prăduite – în ultimul deceniu. Ar deveni vizibile
etapele transferului ilegal de la întreprinderea statului român, C.F.R., la
diverse persoane suspecte. În cazul optimist că ar putea deveni
posibilă identificarea persoanelor implicate, funcţiile acestora, chefurile
destrăbălate şi punerea în dependenţă a şefilor din regionalele

finală a banilor şi a consecinţelor în plan economico-social, s-ar putea

eliminată intenţionat din textul legii, nu corespunde realităţii. Cea
