div class="section abstract"> This study tests the use of thoroughly-evaluated waste plastic pyrolytic oils (WPOs) as substitute fuels in a modern, single-cylinder, diesel research engine. Emissions results are supported by FTIR analysis of exhaust gases, identifying 20 species. The results show that contemporary Tier 4-compliant combustion systems...

There is abundant worldwide research into combustion engine applications for tyre pyrolysis oil (TPO). However, most studies are methodologically outdated in terms of their assumed technology, either with regard to TPO production or engine application, or in their analytical approaches. The variety of radically different studies produce conflicting...

The continuous need for systematization and open dissemination of knowledge on Renewable Fuels intended for use in Internal Combustion Engines forms the premise of the presented Special Issue titled "Renewable Fuels for Internal Combustion". Experts in the field were encouraged to share their latest findings in the form of original research papers,...

The present study is aimed at studying the energy and environmental performance at various engine loads (BMEP) with identical start of injection (SOI) for all fuel types. The combustion parameters for the fuel mixtures were analyzed using the AVL BOOST software (BURN subroutine). Five different blends were tested, consisting completely of renewable...

In the present work, biofuels produced from different raw fatty materials have been proposed asa dominant fuel component in biodiesel–diesel fuel blends. Biofuels were produced from pork lard and rapeseed oil by alkali transesterification usingmethyl alcohol. Blends of biofuels in volumetric proportions of 60 and 80% of the biocomponent and the rem...

Biofuels are one of the short-term alternatives for reducing the well-to-wheel greenhouse gas footprint of transport. In the framework of compression-ignition engine fuels. This study investigates the feasibility of using cold-pressed rapeseed oil as a biocomponent, admixed with distilled tyre pyrolytic oil, as an energy-efficient alternative to co...

For limited period of time article is available free at:https://authors.elsevier.com/c/1VugT3iH40KBE Abstract: In the present paper, laboratory produced, animal origin biofuels (swine lard and turkey lard had been used as raw material for biofuel production) were evaluated in terms of physicochemical parameters and compared with commercial mineral...

The use of renewable fuels can reduce consumption of fossil fuels as well as diversify the range of alternative energy carriers. The advantage of biofuels is that they can be obtained from waste materials. Biofuels derived from vegetable or animal raw fatty material, as a result of transesterification, are characterized by similar physicochemical p...

Biodiesel is widely perceived as a source of ecological energy used to power compression ignition engines as an alternative to fossil fuels. Depletion of fossil fuels and increasing environmental awareness of society has led to an increased demand for energy derived from renewable sources. This phenomenon requires acquisition of raw material used f...

The problem of alternative fuels for combustion engines has been growing in importance recently. This is connected not only with decreasing fossil fuel resources, but also with the growing concern for the natural environment and the fight against global warming. This paper discusses the possibility of utilizing alternative gaseous fuels in compress...

Biodiesel, as a product of the transesterification reaction of fatty material, is gaining appreciation all over the world and confirms its beneficial effect on the reduction of exhaust gases when (even partly) used to power compression-ignition engines. Although many researchers have focused on biofuel production and its application in combustion e...

Growing environmental awareness and responsibility in the tourist industry contributes to the search for innovative solutions aimed at reducing the impact of tourism on the environment. Successful promotion of yachts charter offer, which are auxiliary powered by renewable raw materials, not only draws attention to the fact of emissions reduction, a...

Changes in the global economy connected with globalization of transport cause that logistics and transport are becoming more important in the organization and management of flows of goods by reducing the time and cost of transport services. In 2013 the postal services market has changed significantly. The most important change was the release of th...

Courier services are a special group of postal services. Changes in the global economy of globalization transport cause that logistics and transport are becoming more important in the organization and anagement of flows of goods by reducing the time and cost of transport services. In Poland, the market for Courier, Express and Parcel Delivery Servi...

Intensive development of waterborne tourism in recent years generates new logistical problems in this field. One of such problems is that of efficient management of charter yachts fleets in terms of technical support for the customer. The paper presents the design of an on-board communication network dedicated for small recreational vessels. The ne...

The aim of the study was to evaluate the use of camelina and mustard methyl esters and their mixtures with diesel (in 95:5 and 80:20 proportion) as fuels for compression ignition engines. Esters prepared with acid-base transesterification process methyl were characterized in terms of the lipid composition, kinematic viscosity at 40°C, density at 15...

Due to the continuous increase in prices of conventional fuels, the production of biofuels on an industrial, as well as small scale, nowadays is becoming more economically efficient. However, the usage of biofuels in its pure form is a problem when one have to supply them with modern injection systems. Due to the difference in parameters of biofuel...

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW dies...

Vision of depletion of fossil fuels and associated with the usage negative impact on the environment, resulted in increased interest in finding alternative sources of materials, which may be used to power internal combustion engines. Usage of biofuels to power diesel engines offers a wide range of benefits for the user and also the environment. Bio...

The use of liquid fuels as an energy source for internal combustion engines is unavoidable nowadays, further consumption increases with the development of industry and economic growth of the country. The abundance of the world in fossil fuels is a highly controversial issue, however, irrespective of forecasts concerning deposits of mineral fuels, u...
