Abstract:

The development of a new combustion engines is connected with endeavor for escalation of the total efficiency. Escalation of the total efficiency can be: minimization of the mechanical losses in the combustion engines or minimization of the unsuitable equipment capacity of accessories. Now research and development programs of a manufacturer of the combustion engines search effectual equipment and method for this escalation of the total efficiency. The escalation of the total efficiency is important for a minimization fuel consumption and consequently for lower emissions. The paper deals with t

Abstract:

Recent advances on high temperature air combustion (HiTAC) have demonstrated significant energy savings, higher and uniform thermal field, lower pollution, and smaller size of the equipment for a range of furnace applications. The HiTAC technology has evolved from the conception of excess enthalpy combustion (EEC) to high and ultra-high preheated air combustion. In the HiTAC method, combined heat regeneration and low oxygen methods are utilized to enlarge and control the flame thermal behavior. This technology has shown promise for much wider applications in various process and power industrie

Introduction. The expansion of the fleet of tractors and vehicles causes increased requirements for internal combustion engines. This problem can be solved by improving the work process in a diesel engine that can be achieved by heating the diesel fuel in the fuel supply system. External thermal action is carried out on the high pressure line directly in front of the injectors. Materials and Methods.

Abstract:

Attention of humanity is being increasingly focused on prevention of anthropogenic emissions of greenhouse gases, including CO2 [1]. One of the main contributions to CO2 emissions is associated with the production of electric and thermal energy. Despite great efforts, aimed at developing renewable energy technologies, fossil fuels will dominate in this area of human activity for a very long time. Therefore, the capture of CO2, formed during the combustion of fossil fuels, is of particular importance. If air is used as a fuel oxidizer, the combustion products consist of more than 70% nitrogen.

Abstract:

Fluidized bed technology is very suitable for the combustion of biomass Nevertheless substitution of coal with biomass affects boiler operation and especially dynamics and controllability. Non-homogeneity of biomass and fuel feeding disturbances cause process instability, such as variations in temperatures and pressures, which reduce lifetime of equipment and structures. Because of process instability higher air coefficient must be used in order to avoid CO emissions, which is not economical.

ABSTRACT Evaluation of fuel consumption in internal combustion engines (ICE) of agricultural machinery and equipment is important in determining the performance under various operating conditions, especially when using biofuels. This study consisted of experimental evaluation of the gasoline (petrol)/ethanol consumption in a two-stroke 1-cylinder ICE, Otto cycle, functioning as an air blower for agriculture and related applications. A methodology for tests of non-automotive ICE, based on ABNT/NBR technical standards, was considered. The presented results refer to operation with commercial and

To achieve comfortable operating conditions, the car is equipped with air conditioning. The most common air conditioning devices in transport are air conditioners made on the basis of steam compression refrigerating machines. However, due to the introduction of virtually silent compressors of various capacities on the market, it became possible to return to the use of the simplest and cheapest method of air conditioning – using air-cooled machines. Their use will reduce overall equipment costs, make operation much easier, and increase the reliability of the equipment. The use of sorption refri

For this study, only about 1/3 of the full load fuel engery was supplied due to limitations of the fuel injection equipment used. Three types of ignition methods have been investigated: compression ignition with no ignition aid; separate diesel pilot fuel injection to ignite the CWS fuel; combined CWS and pilot diesel fuel injection (stratified pilot ignition).

Abstract:

Petroleum coke (petcoke) is a by-product of heavy petroleum refining, with heating values comparable to that of coal. It is readily available in oil-producing countries such as the United States of America (USA) and the Kingdom of Saudi Arabia (KSA) at minimum costs and can be used as an inexpensive fossil fuel for power generation. Oxy-petcoke combustion is an attractive CO2 capture option as it avoids the use of additional absorption units and chemicals, and results in a CO2 + H2O flue gas stream that is compressed and dehydrated in a CO2 capture and purification unit (CO2CPU).
