摘要： Breathing system for four-stroke, fuel injected internal combustion engines, wherein each poppet valve of each cylinder accomplishes a dual-duty to serve both as an exhaust valve (in the final process of a given cycle) and subsequently as an inlet valve (in the first process of the following cycle). The passages (external to the cylinder) where the valve ports and stems are located are connected to both the intake and the exhaust manifolds wherein air is forced to flow under pressure by means of a fan (or a blower or a compressor) driven by the engine, in order to sweep away the combustion gases during the exhaust process and subsequently to feed a sufficient amount of fresh air during the intake process.
