Improvements in and relating to internal combustion engines |
| abstract |
An internal combustion engine in which volumetric efficiency is improved by installing a non-return valve, such as a reed valve (16), upstream of the normal inlet valve (not shown), to control air or fuel-air mixture entering the input port (20). In addition, the ram pipe (23) is made longer than usual: sufficiently long so that, at low engine speeeds, the momentum of the air of fuel-air mixture within the induction system is sufficient to force extra volume past the reed valve (16) to pressurise the gas retained between the inlet valve and the reed valve. Also described and claimed is an engine in which power and torque are improved by adding an extra port or ports in the side walls of the cylinder or cylinders. Such additional ports may be used for inlet combustion gases, or for exhaust gases. |
