DYNAMIC REGULATION OF THE PERCENTAGE COMPOSITION OF THE MIX DIESEL AND BIODIESEL FUEL

The use of internal combustion engines increase environmental pollution and dependence on fossil fuels. The biodiesel fuel, which is renewable, more environment friendly, and cheaper, is a good alternative for diesel engines. The use of biodiesel fuel leads to a drop in diesel power and an increase in fuel consumption. To prevent these shortcomings, it is proposed to use dynamic regulation of the percentage composition of a mixture of diesel and biodiesel fuel. The modernization of diesel

ANALYSIS OF HYDROSTATIC MECHANICAL TRANSMISSION EFFICIENCY IN THE PROCESS OF WHEELED VEHICLE BRAKING

To analyze the braking process of a mine diesel locomotive with hydrostatic- mechanical transmission (HSMT), a mathematical model has been developed. In contrast to available models, this one takes into consideration rules of changes in controlling the parameters of hydrostatic drive (HSD) and implementation methods for the braking process. Moreover, the model makes it possible to study changes in kinematic parameters, power parameters, and energy parameters of HSMT under various conditions of

EMISSIONS FROM A MEDIUM-DUTY CRDI ENGINE FUELLED WITH DIESEL–BIODIESEL BLENDS

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

The paper considers the problems related with diagnosing diesel engine crank gears, and presents most widely used methods for their diagnosis. The authors provide arguments in favour of dynamic health status identification of connecting-rod bearings in terms of the oil layer thickness. For the first time the dependence is obtained of the oil layer thickness in conrod bearings from the rotation frequency of the crankshaft and the pressure in the lubrication system.

Main conditions and effectiveness of gas fuel use for powering of dual fuel IC self-ignition engine

Internal combustion engines are fuelled mostly with liquid fuels (gasoline, diesel). Nowadays the gaseous fuels are applied as driving fuel of combustion engines. In case of spark ignition engines the liquid fuel (petrol) can be totally replaced by the gas fuels. This possibility in case of compression engines is essentially restricted through the higher self-ignition temperatures of the combustible gases in comparison to classical die-sel oil. Solution if this problem can be achieved by using
