The Devices for the Transport Diesel Engines Constructive Adaptation for Their Operation by Biodiesel Fuel

Abstract

The research is devoted to possibility of mineral diesel fuel with mixed biodiesel fuel partial replacement, which contains the vegetable oil as a biological component (such as: rapeseed, camelina, radish, mustard, colza, soybean, etc.). Constructive versions of bi-fuel supply system and mixers for diesel engines adaptation for their operation by biodiesel fuel are offered. The advantages of the developed bi-fuel systems and mixers are: universality in relation to different types of diesel engines; polyfuelness; availability of components; competitiveness; possibility of production in the plant conditions, no requirement of big capital investments, the small term of payback. The application of the offered system by the diesel-powered machinery provides the necessary percentage ratio of mixed fuel components depending on the load-speed mode without its essential constructive changes. The using of the mixed biodiesel fuel containing for example 50% of mineral fuel and 50% of camelina oil allows to save 50% of petroleum diesel fuel, to reduce smoke of the exaust gases by 17-20%, to reduce the content of carbon oxide by 35-40% in comparison with the work of the diesel engine on mineral diesel fuel, by insignificant decreasing of the effective power (no more than 6%) and by some increasing of specific fuel consumption of mixed fuel (to 14%).
