Externally, the first internal combustion engine resembled either a fire hydrant or a sewing machine. The next hundred and fifty years were spent in search of the ideal design. The engine design was constantly modernized, increased or decreased in size, superchargers were added, the fuel supply system was changed... In general, it was not immediately possible to find optimal solutions. But the engineers did not give up, and now the internal combustion engine is the king of the automotive world. #dvs #howitworks #engine #motor #car #auto
