Abstract

This invention relates to mechanical engineering and makes it possible to increase the effectiveness of reducing toxicity. For this, in the zone of the receiver 8, the cavity of which is connected to the outlet of at least one of the systems of the complex system, a heating element 7 is mounted. The latter contributes to more intensive heating of the gas-air mixture. This improves the evaporation of the liquid phases of the mixture. 1 il.

Description

 The invention relates to machine-building, namely, devices with toxicity and increasing the fuel efficiency of internal combustion engines.

The purpose of the invention is to increase the effectiveness of reducing toxicity.

The drawing shows the internal combustion engine diagram.

; The internal combustion engine has a co-intake system 1 and a complex toxicity system that includes at least one of the following systems: recirculation of 2 exhaust gases, trapping 3 base vapor, ventilation of the crankcase L and supplying 5 secondary air into the intake manifold 6., The latter is mounted heating element 7, located in the zone of river 8, the cavity of which is connected to the output of at least one and | of systems of a complex system. The surface 9 of the heating element 7; in contact with the internal flow jTJocTbro of the intake manifold 6, is filled with holes 10.

The engine works as follows.

When the engine is operating, the gas flows from each of the 2-5 systems into the inner cavity of the receiver 8, where they are intensively mixed, heat and mass transfer. As a result, a gas-gas-air mixture is formed in the cavity of the receiver 8, which is heated by the heat of the electric heating element 7 and from 15218994

working gases from recirculation system 2, which improves the evaporation of the liquid phases of the mixture. In this case, the mixture from the cavity of the receiver through the holes; 4 10 enters the inlet pipe 6, where it is intensively mixed with the fuel-air mixture. At the same time, due to the continuing process of heat and mass transfer of the combustible mixture, the mixture becomes fine, uniform, and the evaporation rate increases. Ultimately, this leads to a more even distribution of the mix

Ci on cylinders, to improve the process of combustion, and this in turn leads to a decrease in engine toxicity, increasing its fuel efficiency.

The best option is when the gas flows of all engine systems are mixed in the same cavity of the receiver. However, the engine works efficiently enough in the case when one of these systems is absent.
