SINGLE-POINT ENRICHMENT OF AIR CHARGE OF AUTOMOTIVE ENGINEERING DIESEL WITH LIQUID ACTIVATORS

Abstract

An effective way to intensify the working process of diesel engines of automotive engineering is to enrich the air charge by supplying a certain dose (10–20%) of a hydrocarbon activator (alcohol, gasoline, kerosene, mineral diesel fuel or mixed vegetable-mineral fuel) to the engine intake pipeline in the intake stroke. For the practical implementation of this method, a single-point enrichment system for an air charge of a diesel engine has been developed. It contains an activator tank with a 10-20% volume of the tractor's tank, an activator filter, an electric pump, an electromagnetic nozzle, an electronic control unit and sensors. The results of comparative motor studies of diesel without enrichment and with enrichment of the air charge with various activators show that single-point enrichment using an electromagnetic nozzle installed at the entrance of the intake manifold improves the power, fuel, economic and environmental performance of the diesel.
