Description
Technical Field
The invention belongs to the field of internal combustion engines and generators, and particularly relates to an integrated high-efficiency auxiliary engine power station system based on a double-crankshaft opposed-piston two-stroke engine.
Background
Most of power devices of the conventional auxiliary power station system are conventional engines adopting the traditional piston layout, the integral size and the fuel consumption rate of the power station cannot be reduced due to the inherent structure and the operating characteristics of the conventional engine, and the conventional engine runs counter to the design targets of integration, high compactness, high reliability and low fuel consumption required by the auxiliary power station system. Compared with the conventional engine, the opposed piston engine has the advantages of simple structure, less parts and low cost, cancels a complex valve actuating mechanism and a cylinder cover, greatly reduces the weight and the volume of the engine, and can effectively improve the power density of the engine. The elimination of the valve actuating mechanism can also reduce the number of friction pairs, reduce the friction loss and improve the mechanical efficiency of the engine. The elimination of the cylinder cover can reduce the volume of a cooling system, reduce cooling and heat dissipation and improve the heat efficiency of the engine. In addition, two pistons of the engine reciprocate in the same cylinder in opposite directions, so that the engine has good self-balance, small vibration and small running noise. The two-stroke opposed piston engine completes the air exchange process through the air inlet and the air outlet which are arranged at two ends of the cylinder sleeve in a sweeping way by the piston, does not need an air valve, a high-pressure nozzle and a large radiator, and has high reliability and various fuel compatibility. Based on the advantages, the opposed-piston two-stroke engine can be used as an ideal auxiliary power station system power device.
The existing auxiliary power station system adopts two kinetic energy transmission modes, one is that after an engine flywheel is connected with a crankshaft, a transmission mechanism is driven by a gear ring to carry out mechanical transmission, and the kinetic energy is transmitted to a generator, so that the structure is complex, and the cost of the gear ring is high; the other type is that the belt is connected with a damping belt pulley of an engine, a crankshaft of the engine rotates, the damping belt pulley rotates simultaneously, and then the belt pulley of the generator is driven to rotate through the belt, so that the rotor is driven to rotate to realize power generation. This runs contrary to the original purpose of integration and high-compactness of the auxiliary power station. Therefore, an outer rotor disc type generator can be adopted, the stator support is used for fixing the outer rotor on an engine body, the crankshaft synchronous gear is used for driving the outer rotor, and the outer rotor serves as a connecting gear between crankshafts to transmit power, so that the size and energy loss are reduced, and the integration of the engine and the generator is realized.
