The utilization of plastic solid wastes for sustainable energy production is a crucial aspect the circular economy. This study focuses on pyrolysis as an effective method to convert this feedstock into renewable drop-in fuel. To achieve this, it essential have comprehensive understanding composition, process parameters, and physicochemical characteristics resulting fuel, all correlated with engine combustion parameters. Considering full value chain, provides first unbiased up-to-date...

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 However, most studies are methodologically outdated in terms of their assumed technology, either with regard to TPO production or application, analytical approaches. The variety radically different produce conflicting ambiguous results, rendering TPÓs role as a feasible future fuel uncertain. This study the first provide state-of-the art analysis results thoroughly-evaluated fraction...

Ethyl alcohol is a known additive to automotive gasoline. In commercially available gasolines, its concentration between 5 and 10%. Since ethyl can be considered as renewable fuel, efforts are being made further increase content in This article describes the results of comparison experiments on Euro direct injection spark-ignition car engine fueled with conventional gasoline 30% v/v (E30). The test showed that significant share ethanol fuel did not affect most regulated emissions gaseous...

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on fuel various diesel-biodiesel (B10, B20, B40, B60) blends, at loads speeds. The experimental tests were performed four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW D-243. in-cylinder pressure data was analysed to determine ignition delay, Heat Release Rate (HRR), maximum gradients. influence blends Brake Specific Fuel Consumption (bsfc) exhaust...

The present study is aimed at studying the energy and environmental performance various engine loads (BMEP) with identical start of injection (SOI) for all fuel types. combustion parameters mixtures were analyzed using AVL BOOST software (BURN subroutine). Five different blends tested, consisting completely renewable raw materials based on hydrotreated vegetable oil (HVO) fatty acid methyl ester (FE100), properties diesel (D) compared respect to these blends. mixed in following proportions:...

In the present work, biofuels produced from different raw fatty materials have been proposed as a dominant fuel component in biodiesel–diesel blends. Biofuels were pork lard and rapeseed oil by alkali transesterification using methyl alcohol. Blends of volumetric proportions 60 80% biocomponent remaining part conventional used compression ignition engine designed for medium-duty vehicles. The experiments conducted at two rotational speeds (1500 3000 rpm, respectively) set load conditions...

This paper presents a method of production and properties ethyl esters as well the differences between them methyl esters. It discusses technology esterification benefits brought by use rapeseed renewable fuel. also elements structure, actuators control mechanisms mobile biodiesel plant, owned Department Mechatronics, University Warmia Mazury. An algorithm transesterification process is presented along with algorithms flow-through possibilities their automation. The applying such solution...

The continuous need for systematization and open dissemination of knowledge on Renewable Fuels intended use in Internal Combustion Engines forms the premise presented Special Issue titled “Renewable Combustion”. Experts field were encouraged to share their latest findings form original research papers, case studies, or short reviews. Works targeting all aspects value chain considered necessary, including following: (liquid gaseous) fuel production process, upgrading (catalytic fractional...

Vision of depletion fossil fuels and associated with the usage negative impact on environment, resulted in increased interest finding alternative sources materials, which may be used to power internal combustion engines. Usage biofuels diesel engines offers a wide range benefits for user also environment. Biodiesel interpreted as fatty acid methyl esters obtained from renewable resources by transesterification acids, can an fuel petro-diesel, well pure or additive diesel. Due its “renewable”...

The use of liquid fuels as an energy source for internal combustion engines is unavoidable nowadays, further consumption increases with the development industry and economic growth country. abundance world in fossil a highly controversial issue; however, irrespective forecasts concerning deposits mineral fuels, undisputable fact that these are resources, which will deplete. Economic, environmental legislative issues also impose limitation fuels. Under problems associated interesting...

<div class="section abstract"><div class="htmlview paragraph">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 exhaust gases, identifying 20 species. The show that contemporary Tier 4-compliant combustion systems with split injection can handle high polypropylene-based WPO content fuel without re-calibration. Combustion...

The paper analyses traffic organisation at non-signalised intersections.In such locations, the use of correct road signs is crucial.Traffic engineers should consider a balance between fluency and safety.Sometimes, limited visibility necessitates 'stop' sign.The includes case studies for selected intersections in Silesia Province, Poland.

The manuscript presents a comparative analysis of the performance and emission characteristics compression ignition engine equipped with Common Rail injection system. is fueled diesel-biodiesel mixtures containing 25% 50% share (by volume) renewable components. Conventional diesel used as reference. Turkey lard rapeseed oil are raw materials subjected to single-stage transesterification process obtain methyl esters. experiments performed on medium-duty, turbocharged, inter-cooled, Direct...

Due to the continuous increase in prices of conventional fuels, production biofuels on an industrial, as well small scale, nowadays is becoming more economically efficient. However, usage its pure form a problem when one have supply them with modern injection systems. difference parameters comparison attempt develop mixture optimal for use diesel engines, equipped system, was made. Fuels derived from substrates which are produced independently food and can energize CI engines occupying now...
