Each combustion chamber of the Fourier engine is open to multiple cylinders. which have pistons connected to crankshafts that rotate at different rates. The displacements of the individual cylinders and the relative phases of the pistons are selected according to a Fourier approximation of a prescribed time dependence of the volume of the combustion chamber. The parameters are selecte... https://unitedssports.shop/product-category/bike-parts-tubes/
