ABSTRACT:
Fuel saving apparatus for controlling the supply of fuel to one or more selected cylinders of a multi-cylinder internal combustion engine comprises a remotely and independently controlled fuel saving valve operably positioned to provide selective communication between the cylinder clearance volume and a filtered air portion of the engine carburetor. The valve is closed for normal, full power engine operation, and open for predetermined low engine power demand periods. The opening of said valve so severely reduces cylinder intake vacuum and resultant air-fuel influx as to render temporarily ineffective the cylinder, thereby reducing engine fuel consumption.
