The paper is devoted to the problem of improving of energetic efficiency and ecological safety of automotive diesel engines. To solve this problem, it is proposed to use the method of fumigation of air charge with different liquid activators (alcohol, biodiesel, gasoline, kerosene) in the diesel engine at the intake stroke. For the practical realization of such method, a concept of technical solution was formulated and a theoretical foundation was performed. An algorithm of device, performing automatic activator injection at different speed and load modes, was developed. The technical means (microprocessor unit, electromagnetic injectors and sensors) for single-point and multi-point injection of liquid activator into the intake manifold were designed, patented and researched. Depending on activator type and dose, fumigation of air charge with invented devices promotes to reduce exhaust smoke opacity by 10-50 percent and brake specific fuel consumption by 3-14 percent. Simultaneously, the brake power increases by 3-12 percent. These completed studies confirm the efficiency and practical applicability of fumigation of air charge on diesel-powered automotive machinery.
