Abstract:

For internal combustion engines, engines installed for transport ships, cargo ships, and fishing vessels are mainly diesel engines. The number of engines is increasing due to the development of the maritime and seafood exploitation sectors. Therefore, the high demand for petroleum fuels increases environmental pollution due to engine emissions. Reducing environmental pollution from the combustion of petroleum fuels has become a concern worldwide, especially for internal combustion engines. The exhaust gases from the engine contain harmful substances such as soot and nitrogen oxides (NOx). Fuel

This paper presents an experimental evaluation of the effect of air filter pressure drop on the composition of exhaust gases and the operating parameters of a modern internal combustion Diesel engine. A literature analysis of the methods of reducing the emission of toxic components of exhaust gases from SI engines was conducted. It has been shown that the air filter pressure drop, increasing during the engine operation, causes a significant decrease in power output and an increase in fuel consumption, as well as smoke emission of Diesel engines with the classical injection system with a piston

Abstract:

For many years in the Department of Automobiles and Internal Combustion Engines in Technical University of Radom there are carried out investigations on dual-fuel compression ignition engine in which the ignition is initiated by a pilot diesel oil dose and the applied main fuels have properties similar to those applied in spark ignition engines. The tested fuels were methanol, ethanol, LPG and natural gas. Analysis of the obtained results allowed to make some generalizations and to determine advantages as well as problems which should be solved for higher efficiency, power and durability. The

The paper presents results from an investigation focused on toxicity content in the exhaust gases emitted by an internal combustion compression ignition engine fueled with glycerol-ethanol blends at ratio of 50/50% by volume. The innovative issue of this engine is the application of two high pressure injectors for injecting both glycerol-ethanol blend and diesel pilot fuel at high pressure (over 200 MPa). As known, glycerol is considered a byproduct from biodiesel production technologies, hence its cost is relatively low compared to other renewable alternative fuels which can be applied as fue

The use of alternative fuels is a contemporary trend in science aimed at the protection of non-renewable resources, reducing the negative impact on people and reducing the negative impact on the natural environment. Liquefied petroleum gas (LPG) is an alternative fuel within the meaning of the European Union Directive (2014/94/UE), as it is an alternative for energy sources derived from crude oil. The use of LPG fuel in low-power internal combustion engines is one of the currently developed scientific research directions.

Abstract The reduction of harmful emissions is a popular topic in both scientific and public circles. Contrary to popular belief, emissions from transport are only a small part of global emissions. As shown in the figure, the average of the EU 27 countries attributes only 15% of emissions from transport. From common perspective, vehicles with internal combustion, including diesel engines, will soon be replaced by alternative drivetrains. However at least at the commercial and off-road transportation, the diesel technology it is not so easy, and also the environmental reasons are questionable.

In times of increased efforts to reduce greenhouse gas emissions to the atmosphere from the automotive sector, engineers and researchers are finding effective solutions to achieve this goal. The reduction of carbon dioxide emissions can be achieved by increasing the efficiency of the internal combustion engine or reducing the carbon content in the fuel burned. The combination of both of these assumptions can be the use of modern dual-fuel systems for diesel engines in which the pilot dose of highly reactive fuel is hydrotreated vegetable oil (HVO), which is an ecological substitute for diesel

The reliability and service life of the entire mechanism depend on the antiwear properties of fuels. Traditional anti-wear additives containing sulfur, phosphorus, chlorine, etc., are not applicable in motor fuels due to restrictions on emissions of toxic compounds. To improve the antiwear properties of lubricants, it is possible to use a new class of spatial carbon compounds - fullerene-like nanoparticles (FLNs). Th

Imaging methods have an advantage over non-imaging ones because they allow the droplet to be seen at the point and time where its measurement is required. Non-imaging methods can be divided into two groups: the first, which counts and measures, individual droplets one
