Opis:: The paper presents selected results of tests on the Fiat Panda I car powered by 1.2 dm3 spark ignition engine. The engine had production installed fuel system with the single-point petrol injection. To improve its in-service performance, the engine was fitted with the multi-point injection fuel system. The assessment of the indicators of the work of the engine, fitted with single-point, or alternatively, multi-point injection fuel system, was conducted on the basis of the tests performed on the MAHA chassis dynamometer. First, tests were run for single-point injection fuel system. Next, the same tests were performed when the engine was fitted with the multi-point injection fuel system. In the tests, engine power, torque, fuel consumption and the concentrations of the exhaust gas components were measured. The latter included carbon monoxide CO, carbon dioxide C02, hydrocarbons HC, nitrogen oxides NOx, and oxygen 02. AVL Digas 4000 exhaust gas analyser was used to take measurements of the concentrations of the basic components of the exhaust gas and of the excess air ratio %u03BB. The investigations were conducted by performing the inertia test and by using the dynamometer to determine the basic indicators of the engine operation. In the investigations, the crankshaft rotational speed ranged from 1500 to 6500 rpm with 500 rpm step. The experimental results made it possible to evaluate how the manner and site of fuel delivery affect the engine -work indicators.

Opis:: A scheme has been developed to be utilized for solving the interaction between wing aerodynamic loads and the flexibility of wing structures under a quasi static assumption. The interaction is implemented through a link between the nodes of finite element model and the grids of transonic small disturbance model. The particular finite element responses, namely translational displacement vectors (TDV), are utilised for reconstructing the deflected wing surfaces. So in each iteration, the updated surfaces are involved as the parent for regenerating the TSD grids. The criteria of the Euclidean norm is applied for evaluating the convergency of aero-structure interaction. Catia-V5, is fully employed to manage three dimensional geometries for developing the model of wing structures, calculating grids and aerodynamic loads, as well as for reconstructing the updated wing surfaces. Numerous functions and objects of Catia are employed by conducting particular accesses via component object models using Microsoft Visual Basic.Net. A case study is excersized to demonstrate the interaction in transonic speed. The results shown that the scheme is very good in the way performing the interaction in quasi static condition. The utilization of TDV for generating the deflected wing surfaces indicates the capability of high fidelity deformations with respect to the complexity of finite element model

Tytuł:: Diesel engines with respect to Euro 6 and Bin5/Lev II emission limits

Opis:: The article presents future requirements concerning emission of toxic components of exhaust gases valid for Diesel engine passenger cars. Questions connected with fulfilment of these standards were discussed. Chosen structural solutions permitting fulfilment of future requirements concerning emission were presented. In Europe passenger cars equipped with Diesel engines which get the homologation certificate for the first time the emission limit determined by the standard Euro 6 will be binding from year 2014. The relation to the at present binding limit Euro 5 emission of nitric oxides, the sum of hydrocarbons and nitric oxides as well as emission of particulate matter must be reduced. On the European market use could be made of experience gained during exploitation heavy duty vehicles in which decrease in nitric oxides emission is achieve by means of selective catalytic reduction (SCR). A more complex system of emission appraisal is valid in USA and especially in the states where the so called Californian standards were adopted. On the example of Volkswagen 2.0 TDI engine it was shown that in modern constructions of combustion engines there is still a large developmental potential. In this case the development went in the direction of fulfilment of new very requiring standards of emission of toxic components of exhaust gases. Well known in Europe 2.0 TDI engine which in its new version fulfils the most strict emission standards BIN5/LEV II constitutes the structural basis of the drive unit designed for the American market. Under such conditions the firm Volkswagen belongs to the small number of cars producers who for a couple of year have offered with success, passenger cars equipped with Diesel engines.
