“…Nevertheless, the modern diesel engine has been designed and refined for the combustion of mineral diesel, which has different physicochemical properties. The use of crude rapeseed oil requires special adaptation of injection systems and combustion chambers [24,25]. Under Polish climatic conditions, the main source of plant esters was rapeseed oil.…”

The aim of the research was to analyse the possibility of using neural networks to determine the parameters of the chemical composition of exhaust gases as a function of engine performance parameters obtained from the on-board diagnostics system such as crankshaft speed and engine load index. The subject of the study was a Fiat Panda car equipped with a 1.3 Multijet diesel engine and powered by pure diesel. The tests used the MAHA MET 6.3 exhaust gas analyser and the on-board diagnostics system OBD II. The obtained values of NO x ,O 2 ,CO 2 and PM measured behind the DPF were analysed. For the purpose of building a neural network model, preliminary studies were carried out in non-urban traffic (high-speed route). On the basis of the data obtained, processes of learning neural network structures with approximate properties with backward propagation of errors were carried out. Subsequently, tests were performed on the operational parameters of the vehicle and the chemical composition of exhaust gases in urban traffic. Analysis of the obtained values of the average parameters obtained during the measurement and on the basis of the prepared neural models allows determining the relative differences at the level of not more than 10 percent.

“…Thirdly the average emission factors per vehicle, even though specialised on the specificities of vehicle subcategories, they will not be useful in extreme types of vehicle use, i.e., vehicles driven exclusively on highways, or those driven only for short distances. Lastly, several studies have implemented various factors besides fuel type to analyse consumer preferences [106][107][108][109] for the choice of vehicle type. Consumer preferences vary slightly from one study to another.…”

This study provides a thorough review and analysis of the evolution of the Greek vehicle fleet over the last ~30 years, which is next used for the generation of high granularity fleet projections, the assessment of associated air pollution and the estimation of relevant environmental benefits by 2030. The integrated methodology developed takes also into account vehicle clustering and the Brown’s Double Simple Exponential Smoothing technique that, together with the adoption of COPERT-based emission factors, allow for the estimation of the anticipated emissions in 2030. Expected 2030 emissions levels suggest a reduction across all pollutants compared to 2018, ranging from 3.7% for PM10 to 54.5% for NMVOC (and 46% for CO, 14% for SO2, 28% for NOX and 21% for CO2). We find that Greece is on track with national goals concerning the reduction of air pollution from the transportation sector, which designates the positive contribution anticipated by EVs and new, “greener” vehicles, and sets new challenges for the further improvement of the sector beyond the 2030 outlook.

“…Propane-powered vehicles are effective in a cold climate because the mixture of propane and air enters the combustion chamber in the gaseous state [45]. Previous studies by Raslavičius et al [47], Synák et al [48], and Kim et al [49] on the applicability of LPG as an alternative fuel for transport vehicles revealed the effectiveness of LPG from performance, economic, and safety points of view. The use of LPG in SI and CI transport vehicles also emitted less particulate matter, NOx, CO2, and toxic gases when compared with FB fuels.…”

Human beings naturally move from one location to another in search of basic necessities. Road transportation is a low-cost, versatile, and widely accessible mode of transportation worldwide. However, using fossil-based (FB) fuels in transportation vehicles is inefficient, generates hazardous gases, and worsens environmental degradation. The current work assesses the application of clean fuels such as biofuels, natural gas, electricity, propane, and other emerging fuels to replace FB fuels in transport vehicles. Unlike FB fuels, the use of biohydrogen, biomethane, biodiesel, and bioethanol in transport vehicles resulted in emission reduction by 70 %, 63 %, 41 %, and 54 %, respectively, while electric vehicles lower maintenance costs, ensuring better engine performance, and better engine efficiency. The adoption of natural gas and propane as alternative fuels for transport vehicles is cost-effective, and promotes environmental sustainability. There is a need for targeted financial, infrastructural, and technical investments to further promote the application of these clean fuels for road transport application. The outcome of the study provides updated information and sensitizes automobile engineers, environmentalists, transport fleet operators, governments, and other stakeholders on the benefits derivable in the adoption of clean fuels as alternatives to FB fuels as transport vehicles fuel.
