Abstract
The problem of the military vehicles engines fuelling increases with the growth of the amount of vehicles in the armies. At the same time, another problem with fuel supply in modern engines is the use of bio component additives, which changes characteristics (quality) of the used fuels. Therefore, it is important to take actions to adapt engines to powering with fuels coming from renewable sources.The aim of the research was to evaluate the possibility of feeding the diesel engine (influence on the useful parameters and composi-tion) with mixtures of the unified battlefield fuel F-34/F-35 with biocomponents in the form of anhydrous ethyl alcohol and RME. The tests were conducted during fuelling of the engine with six kinds of fuels: basic fuel (diesel oil), NATO code F-34/F-35 fuel, as well as fuel mixtures: F-34 and RME with different ratio and F-34/F-35 with bioethanol. In the result of the research it was concluded that the parameters of the G9T Renault engine with the common rail fuel system in terms of F-34 and RME consumption (using) decreased in comparison to diesel oil basic fuel. It is not possible to supply the engine with the mixture of ethyl alcohol and F-34 fuel – alcohol pre-cipitation and obliteration of fuel system components
Highlights
Liquid fuels are the most important source of energy on modern battlefield
The rapeseed methyl esters (RME) or bioethanol addition to the F-34 fuel caused diminish of effective power ca. [7,8]%, depending on F-34/RME mixture ratio (Fig 1b). The reason of it is increasing of F-34/RME mixture density and diminishing of a heat value
In Poland they are acquired with processing of rapeseed oil (RME)
Summary
Liquid fuels are the most important source of energy on modern battlefield. Availability of fuels decides about mobility of the army, effectiveness of weapons or other support equipment and delivery of needed amount of supplies. Realisation of increasing requirements of fighting troops in fuels or lubrication oils is one of the most important problems of logistic supplying of a battlefield. It is calculated, that mean use of fuel and lubrication oil may reach 30 kg per one soldier per day [4, 11]. That mean use of fuel and lubrication oil may reach 30 kg per one soldier per day [4, 11] The delivery of such a big quantity of supplies to the army, in terms of enemy interaction on communication systems and supplying infrastructure is an enormous sophisticated problem. It’s final quality is the effect of using additive components added to the base fuel before final distribution of fuel to a vehicle’s tank
