Abstract:

The results of the studies of mechanochemical activation of motor fuels aimed to increase their calorific value and reduce their consumption in automotive internal combustion engines are summarized. Traditionally, the improvement in fuel efficiency and environmental friendliness of such engines is achieved by high-tech modernization of fuel systems. But it can also be achieved by modification of fuels that changes their properties and increases the calorific value. By means of methods of mechanochemistry, using the equipment with low power consumption and a simple process, the mixtures and sep

ABSTRACT Diesel cycle engines are widely used in a wide range of agricultural activities. Recently, with the increasing use of biodiesel mixed with petroleum diesel and the introduction of pollutant emission regulations for agricultural and road machinery, there has been a growing migration from mechanical to electronic fuel injection systems. In this experiment, the primary aim was to verify the behavior of a diesel engine, electronically managed, with controlled variation of the fuel feeding system parameters (injection time and volume injected).

The state-of-the-art of the advantages of using liquefied natural gas as a motor fuel for haul trucks instead of oil motor fuel is considered. It is noted that the energy intensity of the process of rock mass hauling by dual-fuel (gas-diesel) haul trucks is less than that of haul trucks running on diesel only. It is argued that the most promising in relation to heavy-duty mining trucks, is the conversion of diesel engines to gas-diesel operation. The universal integrated procedure for evaluating currently used haul truck on-board cryogenic fuel systems performance is presented. The method of e

Abstract:

Solid carbon (C) is produced during hydrocarbon fuels combustion by the molecules heat decomposition process in a local lack of oxygen. More reactive hydrogen consumed the part of oxygen in the zone of an oxygen-rich mixture, so carbon particles are not gaining access to oxygen. Solid carbon particles are bound to other various materials such as mechanical impurities, sulphates, condensates, and liquid fuel residues, some of them with high toxicity – such as polycyclic aromatic hydrocarbons (PAH). The cause of high solid carbon emissions is a significant inhomogeneity of the mixture up to the

Abstract:

Employees involved in various occupational environments that include vibration machines and any kind of vehicles are adversely subjected to multiple source noise. Thus, the corresponding noise frequencies (and mainly the infrasound ones) present high interest, especially from the viewpoint of sustainability, due to the potential effects on human safety and health (H_S&H) in sustainable engineering projects. Moreover, the occupational safety and health (OSH) visualization (a fact of unveiling the social dimension of sustainability) of occupational workplaces (by evaluating the infrasound an

Abstract:

A model of a diesel engine and its electronic control system was developed to investigate the engine behaviour in a vehicle simulation environment. The modelled quantities were brake torque, fuel consumption and exhaust gas temperature and were based on engine speed and pedal position. In order to describe these outputs the inlet air flow and boost pressure were also modelled and used as inner variables. The model was intended to be implemented on board a vehicle in a control unit which had limited computational performance. To keep the model as computationally efficient as possible the model

The drive to reduce fuel consumption of vehicles equipped with internal combustion engines leads to an increasing share of hybrid drives used in various means of transport. Such hybrid vehicles, thanks to the use of diesel-electric drive systems, allow for a fuel consumption reduction, and thus to reduce the carbon dioxide emissions. This fuel consumption reduction results from a specifically selected energy flow strategy in hybrid systems. This strategy was the focus of the research performed in order to identify the energy flow conditions in a hybrid drive system in driving conditions corres

Abstract:

Turbocharging of internal combustion engines is an established technology used for the purpose of increasing both power density and in some cases the cycle efficiency of diesel engines relative to naturally aspirated engines. However, one significant drawback is the inability to match the characteristics of the turbocharger to the engine under full load and also to provide sufficiently good transient response. Under many conditions this results in reduced efficiency and leads to higher exhaust emissions. The design of turbocharger components must be compromised in order to minimize these drawb

The main classes of sulfur-containing compounds in petroleum fractions are thiols, dialkyl and cycloalkyl sulfides, alkylaryl sulfides, as well as heteroaromatic compounds – benzothiophene, dibenzothiophene and their alkyl derivatives. They have a negative impact on the quality of petroleum products. Growing demands on the quality of oil and petroleum products have led to the search for ways to reduce the sulfur content in oils and which would not lead to deterioration
