The imperative of utilising alternative fuels for the operation internal combustion engines stems from requirements to reduce emissions greenhouse gases and other contaminants, substantial demand fuels, diminishing reserves natural resources. global inclination towards sustainable development necessitates employment biofuels as a substitute fossil fuels. Nonetheless, expenditures on raw materials manufacture biodiesel remain substantial, thus underlining importance exploring solutions...

This article presents the results of a study braking process in terms assessing longitudinal loading condition transported cargo. The existing methods securing cargo do not take into consideration type vehicle used to transport may result being compliance with principles proper protection. paper discusses differences maximum deceleration values achieved by different types vehicles that are structurally suitable for freight transport. As these values, forces acting on also different. and...

The use of biofuel is one method for limiting the harmful impact diesel engines on environment. It also a way gradually becoming less dependent depleting petroleum resources. New resources producing biodiesel are currently being sought. authors produced esters from animal fat waste, obtaining fuel that can power and identifying to utilise unnecessary waste. methyl ester (AME) was using reactor constructed non-industrial production. aim underlying this paper determine whether engine be...

Progressive and increasingly noticeable climate change is forcing the search for new energy sources to reduce greenhouse gas emissions, especially carbon dioxide. One way emissions by gradually replacing fossil fuels with biofuels. The authors of this work addressed production second-generation biofuel. purpose study was produce biodiesel from babassu palm oil (BBuE) first-generation rapeseed (RME), their properties, determine effect addition these biodiesels diesel fuel on selected...

nternal combustion engine has been in existence for a long time, but it is still the scope of research interests and contained subject matter numerous development studies analyses. The paper presents basic goals into engines. A short characteristics piston as an object control adjustment was provided. It indicated that measurements working medium cylinder pressure patterns could be applied to performance engine, especially multi-fuel one. results 1.6 dm 3 X16SZR Opel Astra car, which fuelled...

Climate changes caused by the greenhouse effect make it necessary to look for new sources of energy. One them is waste a biological origin. They are often difficult dispose and such process can be expensive. Increasingly, they used produce biofuels that replace petroleum-based fuels. also an alternative food-based biofuels. The aim work was propose method using fatty generated in plant dealing with tanning animal skins evaluate properties produced authors decided use this biodiesel. A...

The use of biofuels is one way to reduce the increasingly visible harmful effects diesel engines on environment. At same time, it also a gradually dependence depleting oil resources. New sources for biodiesel production are currently being sought out. authors this article have produced esters from animal fat waste, obtaining biofuel that can power while manage unnecessary waste. For be possible, necessary confirm possibility using such compression ignition engines. To end, moribund conduct...

Organic matter is converted into a variety of fuels, including potential replacements for transport fuels. New sources raw materials are being sought their acquisition. One such material that currently attracting growing degree attention hemp. The objective this study was to produce biodiesel from hemp oil ascertain its selected properties and compare them with the obtained rapeseed diesel fuel. A reactor designed non-industrial, local conversion available fatty acid esters used manufacture...

The use of biofuels to power compression–ignition engines makes it possible reduce emissions certain harmful components exhaust gases. purpose this study was determine the influence second-generation on course indicator graphs and heat release characteristics Perkins 1104D-44TA engine. For comparative purposes, same tests were carried out by feeding engine with first-generation biofuel diesel fuel. Babassu butyl esters (BBuE) used as biofuel. second fuel a biofuel—rapeseed oil methyl (RME)....

Transport is the source of numerous hazards both to natural environment and people's health life. Currently, efforts are being undertaken limit negative impact economy, transport included, upon environment, one main concerns ensuring safety people. The sources hazard caused by transportation include, among other things, combustion engines. Their operation generates emission toxic compounds, greenhouse gases noise. This article discusses basic people as well issue fuels used for powering aim...

Abstract A vehicle’s longitudinal acceleration is one the parameters that characterize a motion dynamics and used, among others, to assess comfort of public bus passengers. Rapid braking performed by urban drivers can be deemed passengers as uncomfortable dangerous in some situations, especially for standing This paper presents an analysis bus’s recorded during extreme attempts. The experimental tests were conducted on dry wet asphalt concrete surfaces. test results allow statement lateral...

Road transport is the primary source of atmospheric air pollution, thus posing a threat to human health and life. The aim study was determine impact fuel obtained from plants on ecological properties compression ignition engine. article reports results investigations into modern engine with Common Rail system, powered by RME (rapeseed methyl esters) biodiesel their blends diesel. For comparison, also fuelled conventional diesel oil without ester addition. When powering pure biodiesel, brake...

The development of human civilisation has always been related to an increase in energy demand. growth transportation and the number automobile vehicles service produce a rising demand for fuel. Before piston IC engine is replaced with different effective power source, it necessary use gaseous fuels on larger scale than ever before. natural resources are estimated be much higher crude oil reserves. Additionally, engines can run biogas, i.e. renewable means lowering harmful effect environment....

The measurement of acceleration during vehicle motion can be used to assess the driving styles and behaviours drivers, control traffic, detect uncontrolled behaviour, prevent accidents. on an icy road warn driver about changing conditions related hazards. This paper presents results testing parameters a Ford Transit adapted for passenger transport in critical traffic conditions. It contribute improvement safety. Critical are deemed as sudden braking, rapid acceleration, circular at maximum...

Abstract Modern means of transport are basically powered by piston internal combustion engines. Increasingly rigorous demands placed on IC engines in order to minimise the detrimental impact they have natural environment. That stimulates development research The involves experimental and theoretical investigations carried out using computer technologies. While being filled, cylinder is considered be an open thermodynamic system, which non-stationary processes occur. To make calculations...
