Vliv zatížení vznětového motoru na stálost výkonu
Jašek, Petr
The diploma thesis deals with measurement of performance stability. The theory of internal combustion engines is described in the introduction. It deals with energy conversion, heat balance and combustion engine efficiency. It is shown in details the analysis of the influence of operational parameters on performance stability, in particular combustion air parameters, such as the purity, weight, temperature, pressure and humidity of the intake air. Another part of the thesis is focused on the methodology of measurement on the cylindrical dynamometer, where the preparation and course of measurement is described. The preparation and measurement was implemented on a second generation Škoda Superb with a 1968 cm3 diesel engine with a Common-Rail injection moulding system. First the measurement was done by a dynamic method and then by a static method at full load at different speeds. At each speed level, the measurements were made twice. Firstly, the air conditioning was switched off and secondly the air conditioning was switched on. All possible parameters were read from the on-board car and recorded. Final part of the thesis deals with the processing and evaluation of these measured data during the experiment. Primarily, the air parameters, cooling fluids, are analysed depending on the engine performance.

Vliv spalování paliva CNG na technicko-ekonomické parametry vozidla
Strnadel, Miroslav
This diploma thesis "The effect of CNG fuel combustion on the technical and economic parameters of the vehicle" deals with the use of alternative fuel of compressed natural gas for road vehicles. The thesis is divided into 4 main parts. In the first part there is a literary review, which deals with the history of the use of gaseous fuels in the world and in the Czech lands, as well as the characteristics and construction part of the car modified for CNG operation. The second part is an experimental measurement of performance parameters of two Škoda Octavia Combi III vehicles with a CNG, diesel and petrol engine at dynamometer testing laboratory, which is also described in this chapter. In the third part the results of experimental measurement are processed and commented and both vehicles are compared from the technical and economical point of view. As is evident from the measurement results, in a vehicle that is already equipped with CNG system from manufacturer combustion CNG does not have a negative effect on the engine's performance parameters and even more constant engine operation can be observed. Vehicles with CNG system are also more economical and ecological than vehicles combusting conventional fuels. The last part of this thesis is devoted to a discussion, where the measured results are compared with the results in an expert article dealing with the same topic.

Indikace spalovacích tlaků zážehových motorů
Linhart, Roman
The thesis deals with the indication of combustion pressures of ignition engines. Introduction is devoted to thermodynamics of combustion engines and their diagrams. The following section describes the methods for measuring the combustion pressures of a spark ignition engine. This chapter describes three basic methods of measurement, the most described of which are piezoelectric sensors. The next part is devoted to the design of the measuring chain and to the description of the material used, which was used for the measurement on the engine under test. The main goal of the thesis was to evaluate the results obtained by measuring at the engine testing center of Mendel Uni-versity in Brno. The data were tabulated and graphically evaluated and subsequently described. At the end of the thesis everything is evaluated and the results summarized.

Úplná charakteristika vznětového motoru s využitím dat ze sítě CAN-BUS
Pluháček, Marek
This diploma thesis deals the topic Full characteristics of combustion diesel engine with using data from a CAN-Bus network. This work is divided into two parts. The theoretical part of the thesis described according to available literature kinds of characteristics of the combustion engine and the current state of the measurement characteristics. Then, it is targeted on data transfer in automobiles using a Controller Area Network (CAN-Bus) and the possibilities of using data from a digital network vehicle. The aim of the practical part is to suggest methodology of measuring parameters of engine track tractor John Deere 8320RT. Evaluation of data from a CAN-Bus Net and construction a complete speed characteristic. Determination of the lowest specific fuel consumption, achieved maximum power and torque. The results of measuring and placed in tables which form is a basis for creation of subsequent characteristics.
