Opis:: This paper presents the results of comparative research on basic physical and chemical properties of pure diesel fuel and two types’ mixtures of Camelina oil ester (Camelina oil ester content of the mixture was 10% and 15%) and diesel fuel. Application of these mixtures has different physicochemical properties to power supply diesel engine, made it possible to detect existing differences in the injection process (pumping and spraying). The analysis of the injection process has been defined through experimental graphs of the fuel pressure in injection line and registered height of the needle injector. With the knowledge of these two fast-changing engine parameters and loadvelocity conditions, there were calculated: fuel flow speed from nozzle, range and fuel spray disintegration time and the average critical diameter of the droplets. In the final part of the article it was shown, that the fuel with different physicochemical properties has a significant impact on the injection process. There were also made a comparative assessment of the suitability test compounds for use in service.

Opis:: Some factors defining starting properties of diesel engines are considered. Features of process of fuel feed on a starting mode are analyzed. Basic possibility of steering by processes of mixture forming and combustion is proved at a small speed of a crankshaft. Developed a design procedure of process of fuel feed in a diesel engine at a start regime. On the basis of the theory of transients in a fuel system, the reasons of deterioration of indicators of fuel feed process are explained at a start regime of diesel engine. Possibilities of a method of increase of initial pressure in a delivery highway by prostrating scrolling of a crankshaft with idle spray jets are investigated. The method of intensification of fuel feed process patented by authors used in diesel engine at a start regime. The results of numerical experiments confirming improvement of indicators of process of injection at high-speed speeding up of the pump of a high pressure are resulted: Increase maximum and an average pressure, cutting-down of duration of fuel feed process. The paper concentrates on possibility of improving fuel fed process at the starting regime by means of high speed forcing the fuel pump and the initial pressure rising by an earlier camshaft rotation with out of work injectors.

Opis:: Fuel mixture formation inside a cylinder has become used more frequently in spark ignition engines in recent years. gas internal combustion engines can also benefit from this concept as direct injection into an engine 's cylinder during the compression stroke not only increases its volumetric efficiency but also eliminates adverse anomalies in the combustion process. This paper focuses on the development of a simulation model for a spark ignition engine with direct hydrogen injection into a cylinder. The Wave software was used for the simulation. A part of the paper depicts the model's verification. The study utilized a three-cylinder internal combustion engine with the total cylinder volume of 1.2 dm3. The concept of the engine is based on new, high-pressure injectors with 10 MPa inlet pressure (gas-hydrogen injection directly into the engine cylinder). Utilization of internal fuel mixture formation can be beneficial due to its enabling the control of the combustion process and gaseous emission generation. From the viewpoint of the engine's design, however, internal fuel mixture utilisation is more complicated as injectors have to be built into the cylinder head. The actual engine construction is housed in laboratories of the Technical University of Liberec, Department of Vehicles and Engines.
