FR2493405A1 - Turbulator for IC-engine inlet - has frame between carburettor and cylinder with rotors to homogenise charge - Google Patents

Abstract

The mixing enhancer for the intake of an i.c. engine has a frame retaining movable turbulators. It has a round support on a frame of minimal thickness with a central cutout to retain several turbines. These are fixed to pins and retained by circlips on a support tongue. The frame can hold up to five rotors and is fixed in the intake pipe between the cylinder inlet stub and carburettor. The rotors aid homogenisation of fuel flow and can be used with multi-cylinder engines.

Description

-DESCRIPTION
The present invention relates to explosion engines, makes it possible to reduce gasoline consumption by better homogenization of the oxidizer-fuel mixture which is burned in almost all of it, or a significant reduction in pollution (carbon monoxide).

In known devices of this kind; a cone pierced with holes, a nozzle flange or deflectors creating turbulence, such devices are fixed and lack mixing. Indeed during engine idling for example at a red light in town , the air-petrol mixture is imperfectly burned, the greater pollution, this mixture is not evenly distributed
It is in cities and large cities that these devices are ineffective and release carbon monoxide in high doses.

The device of the invention makes it possible to avoid all these @ disadvantages.

In this one, in fact, the mixture is burned almost entirely at all engine speeds, the carbon monoxide greatly reduced at the same time, the crazy turbine remains in motion, the homogenization of the mixture always follows engine speeds.

This invention saves gasoline, reduces pollution, improves, increases the flexibility of the engine, the efficiency of the engine, facilitates departures, decreases the time of use of the starter, prolongs the life of the engine, acts as a complement to the carburetor, allows a more complete combustion of the air-petrol mixture and thereby decreases the consumption of petrol. It is even possible to reduce the arrival of petrol without losing engine power.

This fuel economy, although low depending on the tests carried out, is around: 8 to 15% approximately. The reduction in pollution is on the other hand quite significant, more than: 50%.

The device which is the subject of the invention has nne on several foIles turbines 3 therefore continuously in motion, mounted on a fixed axis 4, the latter is clipped to its upper part preventing the turbine from going out during depressions of the motour, This turbine has : five 5 è hnit I0 fins, it is made of polymer The axis 4 receiving it is fitted onto a pin 6 located in the hollowed out part 2 of the support I.

The support, round, square 8, rectangular 9 can receive from one to five turbines depending on whether the carburetor is one body, two bodies or more.

The support takes place on the intake pipe in place of the existing gasket between the carburetor and the latter, imprinting the same I0 studs and orifices
The material used by the invention makes it possible to deposit the seal located between the carburettor and the intake pipe, this material withstands hydrocarbon gases and seal office.

The illustrated accompanying drawings, by way of example, an embodiment of the device according to the present invention, as shown, the device can be set to tones the explosion engines having a carburetor as equipment.

The device which is the subject of the invention can be used for all explosion engines, in a precise manner, of a simple and rapid assembly, without particular knowledge.

Industrial manufacturing is easy to implement, the production cost reduced and will, on the one hand save fuel and, on the other hand, considerably reduce the pollution produced by
motor vehicles.
