Abstract

Device for improved efficiency in internal combustion engines of motor-vehicles, comprising an air compressor supplying air downstream of the engine carburetor to which the device is applied. The air passage is controlled by a valve connected to the carburetor throttle. Downstream of the carburetor is a propeller which is rotatably driven by air supplied from the compressor and atomizes the fuel perfectly for mixing it with air.

Claims

1. In a device for improved efficiency in internal combustion engines of the type having a carburetor adapted for supply of an air-fuel mixture to the intake manifold of the cylinders and of throttle valve between the carburetor and the intake manifold, the improvement comprising an air compressor, a passage for admitting air from the compressor into the intake manifold of the engine downstream of the carburetor, regulator means having a variable opening for controlling the air flow from the compressor to said passage, and means rotatably connected to the throttle and acting upon said regulator means for controlling the degree of opening thereof, said regulator means and said means acting thereon being constructed and arranged to provide flow of a predetermined amount of air to said passage when the throttle valve is at a minimum open position, then to provide to said passage a decreased flow of air to an amount less than the predetermined amount as the throttle valve is opened and then to provide a gradually increasing amount of air as the throttle is further opened reaching an amount greater than said predetermined amount and then providing a substantially increased flow of air at maximum opening of the throttle valve.

2. A device as claimed in claim 1 comprising a rigid block mounted between the carburetor and the intake manifold and providing a continuous connection therebetween for flow of the air-fuel mixture, said passage being formed in said block, a propeller being freely rotably mounted in said block in facing relation to said passage with the latter tangential to the propeller.

3. A device as claimed in claim 1 wherein said means acting on the regulator means comprises a cam driven by the throttle valve and having a contour to produce an initial faster opening of the regulator means and then a slower opening as the throttle valve is gradually opened from the closed position thereof.

4. A device as claimed in claim 1 wherein said regulator means comprises an air outlet from said compressor, an inlet to said passage, and a plate adjacent said outlet for controlling air flow from the outlet to the inlet, said plate having a hole therein which is out of registry with said outlet when the throttle is closed, said hole having a first aperture of given size which registers with said inlet when the throttle is in its position of minimum throttle opening, said hole further having a slot of increasing size extending from said first aperture, said slot having a smaller size than said aperture at the juncture therewith, said hole further having a second aperture joined to the slot at the end thereof of largest size, said second aperture having a size greater than the largest size of the slot.
