Control Of Throttle Valves Provided In The Intake System Or In The Exhaust System
(AREA)
Abstract
This method and system are used in four-stroke carburetor engines. It accurately doses and segregates the air-combustible blend in the cylinder by reducing the toxicity of burned-out gases and fuel expenditure. The method entails leading a certain portion of fresh air in the space around the suction valve immediately before the opening of the suction valve. After the opening of the suction valve, a portion of fresh air is led first in the cylinder, and then a blast-air blend from the carburetor. The system consists of a carburetor, fitted with a throttle valve and a pipeline (1), connected on one side to the space surrounding the suction valve (4), while on the other side - to the atmosphere of a drive valve (5), fitted to the discharging collector (6).
