Opis:: The main problem that the automotive industry has been dealing with since the beginning of the XXI century is the need to reduce the exhaust emissions from piston combustion engines. Another, not at all less important problem is the depleting natural resources of crude oil. There are many concepts aiming at resolving of the said issues. One of them is the possibility of application of dimethyl ether (DME) in a classic engine. The paper characterizes this fuel, drawing attention to the aspects related to the adaptation of the engine to this type of fuel, presents the process of its atomization and relevant exhaust emissions.

Opis:: Piston displacement pumps use in common rail fuel injection systems generates very high pressure, reaching even 300 MPa. Maintaining such a high pressure is possible thanks to very precise machining resulting in as little clearance between the piston-cylinder assemblies. Due to very high forces operating in the systems and relatively unfavourable lubrication conditions resulting from using fuel as lubricants, the pumps are subject to wear and consequently lose their operating parameters. The high cost of production of the pumps, resulting from their technological advancement, forced their manufacturers to introduce technologies for diagnosing and regenerating them. The diagnostics consists in removing the pump from the engine and having it verified using a test bed. The first stage consists of evaluating the pump’s flow at null pressure; follow by evaluation of its maximal delivery for the pressure of 100 MPa. The obtained values are compared to the values achieved by a new pump. The effect of negative evaluation on a test bed is the disassembly of the pump, verification of the condition of its parts and replacement of the damaged elements. The authors examined new and used pumps on a tested, aiming to determine the characteristics of delivery of a pump for various pressures. The objective of the research was to identify the actual points in the pump’s operation at which the delivery drops the most due to the wear. The highest difference in delivery was found to exist for the maximal compression pressure. The obtained results were analysed and the possibility of changing the pump diagnostics procedure with the use of a test bed was determined.

Opis:: Common rail (CR) injection systems have been universally applied in passenger car engines for twenty years. Moreover, they are applied on a wide scale in trucks, machinery and stationary engines. They have many advantages such as very good fuel spraying due to high injection pressure, injection dose distribution to several smaller, or less heat generation compared to traditional systems. At the same time, the use of this type of system involves a number of problems. They are characterized, among other things, by the high cost of manufacturing and the high sensitivity to changes in the quality of the used fuel. The most important component of the common rail injection system is the high-pressure injection pump. The authors propose a new, alternative pump design with the hypocycloid drive – the article presents the issue of using this type of pump. Further sections describe the design of a pump utilizing a hypocycloid mechanism; demonstrate beneficial functional features and present selected results of the assembly's dynamic simulation. The pump is also characterized by the possibility of multiplying the piston's pitch while maintaining its diameter. It makes it possible to obtain much greater discharge per operating cycle. Taking into account the considerable quantity of fuel transferring by the pump, was also possible to propose an idea of use of hydraulic booster in such pump. In this field, the authors have presented schematic diagram of a pressure booster with a description of its operation.
