The optimization of the electronic controlled injection

The authors propose a personal model for the calculation of pressure regulator and electromagnetic injection, the volume of fuel injected in cycle and the duration of the injection with the number of rotation at the total full charge load. This kind of mode can be used in the modeling system of electronic gasoline injection monounit or multiunit. To carry out this model it is necessary modeling engines with spark ignition cycle with gasoline injection with a model helping cycle proposed by the authors

The contribution modelling gasoline injection at engines with spark lighting

The authors present the general aspects of theoretical modeling of gasoline injection, the principle modeling of some of the elements of gasoline injection, namely the gasoline pump model and the pressure regulator model. It is presented the general model of a spark engine with gasoline injection. The modeling of the motor cycles with spark engines and gasoline injection suggested by the authors is realized by executing a computer program for determining the variation of the three-dimensional and bi-dimensional parameters with the sub-programs: program for calculating the SIE (dependence according to n and λ at to=-35...+45ºC and po=1·102 kPa); program for calculating the SIE (dependence according to n and to at λ=1 and po=1·102 kPa);program for calculating the SIE cycle with gasoline injection. It was realized a study for calculating the pressure from the admission gallery pga and the admission pressure pa

The connections between the engine speed, the air excess factor and the injections duration for the model suggested by the authors

In this paper the fuel metering scheme is presented for both the multipoint and singlepoint injection system designed by authors. The software outputs are the 3- dimensional variations between angular speed and ambient temperature respectively angular speed and A coefficient

The characteristic for injections times

With help to present parameters in this working are realize on the stand engine: the characteristic from speed at all load, the characteristic from speed at partial load, the combustible consumption's at totally task, the combustible consumption's at partially task In the writing "The characteristic's for revolution at partial's of engine load type 106-10 with injection for gasoline ". the experimental test of settle proposal was determine the performance dynamics and combustible consumption. The equipment for to try is more feet that is existing now. Was using equipment for test of Engines with Spark lightning with help injection of petrol that is present in number one imagines

The dependence of the engines rotation and the environment temperature of the combustibles mass

In this paperwork is presented the fuel charging scheme for both the multipoint injection system design by authors. The software outputs are the 3-dimensional variations between angular speed and outside temperature respectively angular speed. It was effectuated a engines with spark lighting program for the calculation of parameters with the gasoline injection with the under- program: the calculation program of engines with spark lighting parameters (depending on n and X at (.=1 and pu=!TQ2 kPa)

Methodological Aspects Regarding the Planning and Development of Integrated Tourist Routes and Circuits. Case Study: Luncasprie, Romania

The intensification of tourist activities at the level of the Bihor Tourist Destination, in parallel with the increase in the need to diversify the local tourist offer, led to the need to identify new solutions in this regard. Due to the geographical location of the studied area, in the immediate vicinity of the Oradea Municipality, this space, due to the values with which it is endowed with the natural environment and the existing tourist infrastructure, can be constituted as a viable alternative with a role in reducing the tourist pressure in the Oradea area and in diversifying the tourist offer through rural tourism and agritourism. In this context, the present study aims to propose integrated tourist routes and circuits following the analysis of the local tourist potential. The results obtained consisted in carrying out an analysis of the natural environment from a tourism perspective and making some development proposals (three routes and a tourist circuit)

PADIŞ - A GEOMORPHOMETRIC APPROACH

This study presents a unitary morphometric analysis for one of the most spectacular karst sectors in Romania: the closed basin Padiș – Cetățile Ponorului. 2 DEMs was used for this purpose, one derived from the interpolation of level curves and altimetry quotas from topographic maps, on scale 1 : 25000, and the second (generated from LiDAR data) was taken over from the National Agency for Cadastre and Land Registration (ANCPI). We have processed 6 morphometric parameters comparatively (hypsometry, slope, aspect and 3 types of curvatures : profil, plan and general curvature) to highlight the metric features of the relief in the studied area as accurately as possible. The results show that the surface relief in Padiș is mature, with an average altitude of 1268 m, in which prevail the slopes with moderate tilt (6 - 17), predominantly sunny and semi-sunny. The relation between the general curvature values and the hydrogeologic features of the area explains the distribution of the sectors with underground water loss and also the disorganized distribution of the surface hydrographic network
