Improvement of diesel engine ecological and economic parameters by using hydrogen

Abstract

Exhaustion and rising cost of fossil energy resources stimulates the search of ways to minimize their consumption. In the transport sector the main energy source is liquid fuel. Due to combustion of that fuel noxious gas is being emitted to atmosphere and creates the “greenhouse” effect, as well, as smog. Reduction of oil reserves increases the price of fuel as well, therefore the search for various alternatives is being made. One of them is usage of hydrogen as a supplement to the traditional fuel. During combustion of hydrogen toxic gases are not emitted. For obtaining hydrogen in a car a hydrogen generator which extracts it from water by electrolysis usually is used. The benefit of using hydrogen is better efficiency of an internal combustion engine. Hydrogen helps to reduce fuel consumption and emission of noxious gas as well. Research of efficiency and emissions of an internal combustion engine using hydrogen as an additive to the traditional fuel has been carried out, computational model to determine fuel costs and exhaust gas emissions under different working conditions has been developed.
