Abstract

The invention relates to methods for operating an internal combustion engine with an additive to a fresh oxygen-air mixture that activates the combustion process. To increase efficiency and simplify the design, oxygen additive is produced between the throttle valve and the manifold branch point. In this case, the volume of oxygen introduced into the fresh mixture is recommended to be kept in the range of 0.05-1% of the volume of oxygen sucked into the engine as part of the air. 1 il.

Description

The invention relates to the field of mechanical engineering, in particular, engine-building, and specifically to methods of operating internal combustion engines using an oxygen additive to charge charge beet.

The purpose of the invention is to increase efficiency and simplify the design.

The drawing shows a diagram of the engine that implements the described method.

The inlet pipe 1, provided with a carburetor 2, is connected to the engine cylinders 3-6 through a manifold 7. The air intake valve and the throttle valve 8 and 9 are placed in the inlet pipe 1. A cylinder 10 or other oxygen source or oxygen-enriched air with oxygen is supplied pipe 11, equipped with a throttle channel 12, is connected to the inlet pipe 1 between the manifold 7 and the throttle valve

9. A reducer 13, a manual dosing valve 14 and a control valve mechanism 15 are placed in the supply pipe 11. The latter is connected through channel 16 to a manifold 7. The oxygen cylinder 10 is equipped with a valve 17.

Before starting the engine, the valve 17 of the cylinder 10 with compressed oxygen and the gearbox 13 are opened. When started under the action of a vacuum in the manifold 7 through channel 16, the control valve mechanism 15 is activated. Before this, the manual metering valve 14 partially opens. By starting the engine using a manual dosing valve 14, increase the oxygen supply (through the throttle channel 12 behind the valve 9 to achieve the maximum stable shaft rotation speed at idle. At the same time, exit from channel 12 at an angle of 90 to the main flow of the combustible mixture behind the throttle valve 9, oxygen supply provides turbulence and

sawing the mixture stream and enriching it with oxygen, improving the processes of mixture formation in the engine and the processes of combustion of the mixture in it. At the same time, a partial decrease in the vacuum in the intake pipe 1 occurs and, as a result, the gasoline supply by the carburetor 12 is reduced. The reduction in gasoline supply is compensated for by the improvement of the processes of mixing and combustion of the working mixture without reducing the engine power. The oxygen supply is regulated individually for idle rotations of this engine using a manual dosing valve 14 and during the operation of the engine the oxygen supply is not changed. When the engine reaches the average or maximum shaft rotational frequencies, the need for additional oxygen is reduced, the processes of mixing and combustion occur more efficiently. Oxygen supply
