Fossil fuels are exhausting quickly because of incremental utilization rate due to increase population and essential comforts on par with civilization. In this connection, the conventional fuels especially petrol and diesel for internal combustion engines, are getting exhausted at an alarming rate. In order to plan for survival of technology in future it is necessary to plan for alternate fuels. Further, these fossil fuels cause serious environmental problems as they release toxic gases into the atmosphere at high temperatures and concentrations. The predicted global energy consumption is increasing at faster rate. In view of this and many other related issues, these fuels will have to be replaced completely or partially by less harmful alternative, eco-friendly and renewable source fuels for the internal combustion engines. Hence, throughout the world, lot of research work is in progress pertaining to suitability and feasibility of alternative fuels. Biodiesel is one of the promising sources of energy to mitigate both the serious problems of the society viz., depletion of fossil fuels and environmental pollution. In the present work, experiments are carried out on a Single cylinder diesel engine which is commonly used in agricultural sector. Experiments are conducted by fuelling the diesel engine with bio-diesel with LPG through inlet manifold. The engine is properly modified to operate under dual fuel operation using LPG through inlet manifold as fuel along FME as ignition source. The brake thermal efficiency of FME with LPG (2LPM) blend is increased at an average of 5% when compared to the pure diesel fuel. HC emissions of FME with LPG (2LPM) blend are reduced by about at an average of 21% when compared to the pure diesel fuel. CO emissions of FME with LPG (2LPM) blends are reduced at an average of 33.6% when compared to the pure diesel fuel. NOx emissions of FME with LPG (2LPM) blend are reduced at an average of 4.4% when compared to the pure diesel fuel. Smoke opacity of FME with LPG (2LPM) blend is reduced at an average of 10% when compared to the pure diesel fuel.

Positive Effects

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

Combustion Engines

Today, internal combustion engines are very common as energy sources in many countries around the world. This makes the tasks related to improving the environmental performance of internal combustion engines relevant. The introduction of alternative fuels in internal combustion engines is an effective way to reduce their negative impact on the environment. One of the most available and widespread alternative fuels for diesels is a water-fuel emulsion. The use of water-fuel emulsion makes it possible to reduce the specific fuel consumption of petroleum origin, as well as to achieve a significant reduction in emissions of harmful substances from diesel exhaust. However, due to differences in the physical properties of traditional diesel fuel and water-fuel emulsion, the course of the processes of mixture formation and combustion in the diesel cylinder changes significantly. This may be due to the emergence of a reserve for further improvement of the diesel engine by selecting the parameters of the diesel engine running on water-fuel emulsion. The study selected the following parameters for variation: compression ratio, boost pressure, duration of the injection process, injection timing. The article considers the influence of these parameters on the Brake-specific fuel consumption of diesel, the specific emission of particulate matter and nitrogen oxides, the maximum pressure in the cylinder. The nature and degree of influence of changes in the parameters of the diesel engine on its performance was determined using mathematical modeling. It should be noted that the influence of each of the parameters selected for variation is quite complex and often ambiguous. That is, when some indicators improve, others may deteriorate somewhat. Therefore, in order to select the most rational parameters of a diesel engine running on a water-fuel emulsion, it is necessary to simultaneously assess the economic and environmental performance of the diesel engine. For this assessment, a method was used to determine a comprehensive fuel and environmental criterion for a diesel engine running on a water-fuel emulsion. Thus, the article shows the potential for comprehensive improvement of environmental and economic performance of the diesel engine by choosing rational parameters.

Fuel Balance

Local types of fuels occupy 33.6% in the fuel balance of the Kirov region. The share of con-sumption of local fuels in the region is one of the highest in Russia. The Vyatka State University (VyatSU) in cooperation with the Belarusian State Agricultural Academy (BSAA) carry out the tests of the operation of automotive diesel engines on fuels with rapeseed oil (RO) and ethanol (E) additives, and spark internal combustion engines with generator gas (GG) additives. A new area of work of the scientific school is the study of the use of multicom-ponent compositions of biofuel compositions (MKBTK-15 and MKBTK-25). The use of such com-positions as a fuel compensates some of their distinctive properties for further use in internal com-bustion engines without changing the design and adjustments. The use of alternative fuels (AF) in internal combustion engines is a main topic for research. However, the use of any AF requires that the environmental indicators of the engine remain within acceptable limits. An important task is to determine the dependences of the emissions of toxic com-ponents on the load. The use of MKBTK-15 and MKBTK-25 as AF for engines will improve the environmental sit-uation in the region and reduce the need for commercial fuel. The operation of a diesel engine on multicomponent biofuel compositions makes it possible to reduce the smoke content of exhaust gases by 65% and 85%, the content of total nitrogen oxides remains at the same level or slightly decreases. There is a slight increase in the content of carbon dioxide СО2 up to 22.3%, but the solutions to this problem are already known. One of the ways is to preserve and increase boreal forests, which have great potential for absorbing greenhouse gases.

Fusel Oils

Currently, the disposal and recycling of the alcohol industry products creates a number of difficulties due to the lack of well-established recycling lines in Ukraine. Since 1998, eight enterprises of the state-owned concern Ukrspirt have been converted to produce high-octane oxygen-containing additives (CFCs) for ethanol-based fuels to organize the processing of waste from the alcohol industry. During this time, they produced 28.2 thousand tonnes of CALs, but CALA enterprises face great difficulties in selling their products, as they are new and expensive. The influence of fusel oil additives on commodity fuels on the main physical and technical indicators of the obtained alternative fuels is considered in the paper. According to the results of studies of octane number, we have established the optimal compositions of fuel mixtures of fusel oils with gasoline A-80 can contain up to 10% of the latter. For mixtures of fusel oils with diesel fuel by cetane number, their optimum content in diesel fuel is from 4 to 10% by volume. But, according to the trends of the development of diesel engines, the compression ratio increases, which allows the use of diesel fuel with higher cetane number, and therefore it is possible to raise the content of fusel oils in diesel fuel to 12%. According to the results of studies of the environmental performance of the ZIL-130 engine when fusel oils are added to commercial gasoline in an amount of 2 to 10% vol. the CO content in ICE exhaust gases decreases by 9.3%, fuel consumption increases by 6.5%, hydrocarbons by 10.2% and nitrogen oxide by 16.9%. As a result of increasing the content of fusel oils in diesel from 0 to 6%, there is an increase in mass flow rate of fuel to 6.1%, an increase in the concentration of hydrocarbons to 10% and nitrogen oxides by 1.9% in the exhaust gases of the engine D21A1. Thus, as we see today, along with traditional fuels for internal combustion engines, it is possible to use their alternative substitutes quite efficiently both in their pure form and in mixtures with them. There are all prerequisites for this in Ukraine and the region, the only question is the financing of these projects.

Pure vegetable oils have the greatest promise for alternative fuels for internal combustion engines beside the depletion of conventional petroleum resources. Among various possible options, pure vegetable oils present promising of greener air substitutes for fossil fuels. Pure vegetable oils, due to the agricultural origin, liquidity, ready availability, renewability, biodegradability are able to reduce the CO2 emissions in the atmosphere. Also, in Vietnam, pure vegetable oils such as soybean oil (SoO100), coconut oil (CO100) and sunflower oil (SuO100) are available. The paper presents the results of using heated pure vegetable oils for diesel engine D243 with power of 80 hp (58.88) kW. The results of determining the power (Ne), specific fuel consumption (SFC) and efficiency (n) are used to evaluate the performance of engine. The results show that, the engine power (Ne) is 10%-15% lower, the SFC of engine D243 using pure vegetable oils is 3%-5% higher and the η is 2.5%-6.2% lower compared to diesel oil (DO). Among the pure vegetable oils, the best performance results for D243 diesel engine are obtained from heated pure sunflower oil up to 135oC.

The prospects of using hydrogen as a motor fuel are noted. The problems that arise when converting a diesel engine to run on hydrogen are considered. The features of the organization of the working process of enginesrunning on hydrogen are analyzed. A method of supplying a hydrogenair mixture to a diesel engine is investigated. To supply hydrogen to the engine cylinders, it is proposed to use the Leader4M installation developed by TechnoHill Club LLC (Moscow). Experimental studies of a stationary diesel engine of the D245.12 S type with the supply of hydrogen at the inlet obtained at this installation are carried out. At the maximum power mode, the supply of hydrogen from this installation to the inlet of the diesel engine under study was 0.9 % by weight (taking into account the difference in the calorific value of oil diesel fuel and hydrogen). Such a supply of hydrogen in the specified mode made it possible to increase the fuel efficiency of the diesel engine and reduce the smoke content of exhaust gases, carbon monoxide and unburned hydrocarbon emissions.

The intensity of infrared radiation emitted by objects depends mainly on their temperature. One of the diagnostic signals may be the temperature field. In infrared thermography, this quantity is used as an indicator of the technical condition of marine objects. The article presents an overview of the use of infrared thermography for the diagnosis mainly of marine piston floating objects and various types of reciprocating internal combustion engines as well as examples of own research results. A general introduction to infrared thermography and common procedures for temperature measurement and non-destructive testing are presented. Experimental research was carried out both in laboratory conditions and in the operating conditions of sea-going vessels. Experimental studies consisted of the presentation of photographs of the same objects made in visible light and the use of infrared thermography. The same objects were also compared, but for different cylinders of the tested internal combustion engines as well as for the up state and fault state. The characteristics of the temperature values at selected points were taken depending on the engine load along with the approximation mathematical models of these dependencies.

Homogenous Charge Compression Ignition

Ammonia (NH3) is an excellent hydrogen (H2) carrier that is easy to bulk manufacture, handle, transport, and use. NH3 is itself combustible and could potentially become a clean transport fuel for direct use in internal combustion engines (ICEs). This technical review examines the current state of knowledge of NH3 as a fuel in ICEs on its own or in mixtures with other fuels. A particular case of interest is to partially dissociate NH3 in situ to produce an NH3/H2 mixture before injection into the engine cylinders. A key element of the present innovation, the presence of H2 is expected to allow easy control and enhanced performance of NH3 combustion. The key thermochemical properties of NH3 are collected and compared to those of conventional and alternative fuels. The basic combustion characteristics and properties of NH3 and its mixtures with H2 are summarized, providing a theoretical basis for evaluating NH3 combustion in ICEs. The combustion chemistry and kinetics of NH3 combustion and mechanisms of NOx formation and destruction are also discussed. The potential applications of NH3 in conventional ICEs and advanced homogenous charge compression ignition (HCCI) engines are analyzed.
