“…There has been a growing interest recently in the use of the exergic method of research in analysing the qualitative aspects of energy utilisation in various power units. The results of studies of internal combustion piston engines by exergic method are presented in works [4][5][6][7][8]. The use of this method provided the solution of problems of optimization of engine operation control, its temperature state, adaptation of the engine to operating conditions.…”

Improvement of technical objects and systems energy efficiency, the most widespread of which are heat engines, is an urgent task, for the solution of which it is necessary to use various methods. The review of scientific publications allows to single out the exergic analysis based on the exergic balance of power installations of different purpose and design as one of the basic universal methods of energy efficiency estimation. Substantiation of universality of the exergic analysis method on the basis of its theoretical preconditions is given. The basic reserve of increase in power efficiency of thermal engines is the rational use of secondary power resources. With the purpose of an estimation of prospects of use of power resources of heat-carrying agents of cooling systems) the calculation of the heat pump working on a reverse Rankine cycle is executed. On the basis of the executed calculations, the conclusion about prospects of use of the given devices, including for replacement of independent boilers in ship power installations is made. The article contains proposals on use of the exergic method in a complex with traditional methods of estimation of power efficiency of complex technical systems. Advantages of such approach are shown, its possibilities and perspective fields of application are determined. The data obtained as a result of conducted research shows that the use of secondary energy resources of heat engines with the use of recycling turbines and heat pumps of modern designs is promising and allows increasing the fuel utilization factor of reciprocating and gas turbine engines.

“…An effective way to decrease fuel consumption is to reduce the influence of various sources of energy loss [23]. Even the newest combustion engines convert only part of the fuel's chemical energy into useful energy (38%) [24]; the remaining energy is lost, among others, through heat dissipation through the cooling system (16-35%) or exhaust gases (23-37% depending on the engine type) [25][26][27]. Of the obtained usable energy, almost one-third is lost to overcome frictional resistance in the engine system.…”

Reducing fuel consumption to decrease CO2 emissions has become a key development factor in the automotive industry. An effective way to decrease fuel consumption is to reduce the influence of various sources of energy loss. One way to increase engine efficiency is to use low-viscosity engine oils to reduce friction losses in the engine’s tribological systems. The aim of the article was to analyze the relationship between the type of engine oil and fuel consumption in a group of 12 passenger cars. This was a homogenous group of identical cars, equipped with the same engine, operated under very similar conditions. Three groups of engine oils (Revline, Total, Orlen) were tested in vehicles and stressed with comparable workloads. The experiment was conducted over two years (two stages of research). The collected results were presented using graphs and compared using statistical tests, split into two stages of research, with four seasonal temperature groups. The study provides a detailed description of fuel consumption differences taking into account variations in ambient temperature. The analyses were focused on finding answers to two research questions: does the type of engine oil affect the variation in combustion levels, and what is the variability of fuel consumption in different seasons due to the ambient temperature variability? Briefly, in both stages of the study, vehicles using Revline oil attained the highest average fuel consumption throughout the study period. Vehicles using Total oil showed similar results to those using Revline oil, with the difference in fuel consumption not as noticeable during warmer months. Conversely, vehicles using Orlen oil demonstrated the lowest fuel consumption values during colder months, but higher levels during warmer months.

“…EFI or electronic fuel injection consists of three systems namely, electronic control system, fuel system and air induction system. Of the three systems, the air induction system has an important function, namely to distribute clean air into the combustion chamber or cylinder [3]. If the air induction system does not work properly, it is certain that the combustion process of the fuel and air mixture will not be carried out perfectly.…”

The purpose of this study is to examine the Air Induction System on the Toyota Soluna 5A-FE Engine Stand. The research method used an experimental method and was carried out for two months from July 2020 to August 2020 at the Padang State University Workshop.How to check the components of the Toyota Soluna 5A-FE engine stand air induction system is divided into three ways, namely, voltage check, resistance check, and visual inspection. The purpose of examining the air induction system on the Toyota Soluna 5a-fe engine stand is to repair the Toyota Soluna engine stand in the FT UNP automotive workshop so that it can be reused as material for the teaching and learning process in the FT UNP automotive workshop. The Toyota Soluna 5a-fe engine stand in the FT UNP automotive workshop is in a dead engine condition, the wiring system is messy and some parts of the stand are porous. Therefore, the author will examine the air induction system on the Toyota Soluna 5a-fe engine stand. The inspection process for the Toyota Soluna 5a-fe engine stand air induction system consists of: the process of dismantling the components of the air induction system, the process of checking the components of the air induction system, the process of repairing the wiring system, the process of installing components after the inspection process is complete, the testing process is carried out and the Toyota Soluna engine stand can live normally so that it can be reused as teaching material in the FT UNP automotive workshop.
