The history of ethanol-petrol blend application is summariserd. Past and future changes in the design of automotive engines are outlined. The properties of ethanol and petrol and their blends are compared. Early and recent reports on the performance of ethanol blends are summarised. The oil crisis coupled with the fact that likely contenders to replace present engines will operate efficiently o...

Detection of fuel adulteration in real time is the most important need of the world as it generates the hazardous effects on the environment, living and nonliving things. Various automotive users and fuel providers may mix kerosene in petrol and diesel. Adulterated fuel increases air pollution, as well as reduces the performance of vehicle engines. Such a malpractice in fuel is prevailing becau...

OBJECTIVES This article compares 2 variants of logging technologies at the motor-manual level: variant A - cutting and delimbing by means of a petrol chainsaw, skidding with the use of a cable winch mounted on a tractor (67-74 kW); variant B - cutting by means of a petrol chainsaw, skidding, debranching and cutting to length by means of a processor aggregated with a farm tractor (61 kW). MATE...

The European Union takes significant steps to support the development of electric sector automotive market. This is confirmed by signed declaration in Glasgow, which leads a ban on sale cars with combustion engines from 2035. document changes car industry and makes it dependent electricity production. problem identified this article actual impact implemented solutions concerning type engine off...

Facing global climate change and the oncoming shortage of fossil resources, it is necessary to reduce overall primary energy consumption. There is a strong need for action concerning car traffic as a main originator of greenhouse gas emissions by use of fossil energy. For a strong mitigation effect, the technological improvement of today‘s petrol and diesel engines has to be accompanied by the ...

In this review, recent models for the heating/evaporation of multicomponent and blended fuel droplets their implementation into numerical codes, used analysis processes in internal combustion engines, are reviewed. these models, diffusion species, recirculation, temperature gradient inside considered. The focus review is on group based analytical solutions to heat transfer species equations cod...

Biogas is competitive, viable, and generally a sustainable energy resource due to abundant supply of cheap feedstocks availability wide range biogas applications in heating, power generation, fuel, raw materials for further processing production chemicals including hydrogen, carbon dioxide biofuels. The capacity based has been growing rapidly the past decade with global electricity generation i...

Petrol powered traffic has replaced domestic heating and industry as the main causes for urban air pollution (Colvile, Hutchinson, Mindell, & Warren, 2001). Automobile combustion engines are responsible for the better part of a city’s CO2 and NOX pollutants. The amount of pollutants emitted by a vehicle largely depends on fuel consumption: the more fuel the vehicle consumes, the higher its emis...
