lineal drive electric generating equipment the abovementioned electric generating equipment can be equipped on the upper side of the upper piston and is moved by a rod extended from the upper piston as shown in fig2 in order to avoidance of the electric generating volume limited by the space of the pressurizing cylinder and in order to getting better power match of the engine power and the electric generating power or in order to keeping the pump drive function of the piston on the pressurizing gas chamber in fig2 the upper link 701 is connected with the upper side of the upper piston 108 the gas seal cover 702 is used for the sealing of the upper gas chamber cover and the upper link 701 no 701 is magnetizing pole 704 is electric generating winding 705 is magnetic circuit iron core the selection of the structure design for the electric generation can be done as the abovementioned one thus the magnetizing pole and the electric generating winding are equipped inversely and the electric energy is transmitted to the middle moving parts using the conducting rod and the carbon brush or the soft conducting wire in this type of the design the diameter and the relative dimensions can be selected for the power match in the electric generating equipment the abovementioned lineal drive electric generating equipment can be used for the traditional engine see fig2 its structure character is same as the abovementioned.
