METHOD AND DEVICE FOR PREPARING FUEL-AIR MIXTURE FOR INTERNAL COMBUSTION ENGINE

摘要

A method for preparation of a fuel-air mixture consists in that the overrich flo w of the fuel-air mixture before its mixing with a second flow is additionally heated by passing it through an activator hea ted up to a temperature exceeding the ignition temperature of the mixture and by providing for multiple contact of the flow wit h the surface of the activator. The device comprises a heat exchanger (1) connected through an inlet sleeve (3) to the exha ust manifold of the engine, and a device (5) intended for dosing the components of the mixture to be treated and provided wit h an air pipe (6), an exhaust gas pipe (7) and a fuel pipe (8). The device (5) is connected through a controlling unit (10) and a mixing pipe (9) to the inlet mixture circuit of the heat exchanger (1). In the outlet pipe of the heat exchanger is mounted, without a gap, an activator (12) which is a heating element with a developed surface, which may have different designs.
