Problems solved by technology
However, the above two solutions have certain defects. Adding one or two brackets at the bottom of the engine will inevitably increase the cost, and the unbalanced center of gravity of this bracket will greatly reduce the life of the bracket. The aluminum alloy structure will also greatly increase the cost, and the weight of the whole machine will also greatly increase, which is not conducive to the lightweight requirements of the generator set

The invention discloses an engine crankcase and an engine thereof. The engine crankcase comprises a crankcase body and a crankcase cover matched with the crankcase body. The crankcase cover is provided with a first supporting mechanism for supporting the engine. The crankcase body is provided with a second supporting mechanism which is matched with the first supporting mechanism to form balanced supporting on the complete engine. Through the combined action of the supporting mechanism arranged on the crankcase body and the supporting mechanism arranged on the crankcase cover, the supporting center of the engine can be well coincided with the gravity center of the complete engine, stable equilibrium of the engine in the working process and after the engine is installed is ensured, and vibration produced during working of the engine is reduced; and external installation brackets or integral type aluminum alloy fan covers in the prior art can be prevented from being used, the cost is greatly reduced, and the assembly weight and the complete engine weight are decreased.
Description
technical field [0001] The invention relates to the field of engine components, in particular to an engine crankcase with good support and an engine thereof. Background technique [0002] Existing frequency conversion generator sets usually use the engine as the power source, and the stator and rotor of the generator are integrated into the engine power, wherein the magneto rotor of the generator is integrated on the flywheel, and the magneto stator coil is installed under the flywheel. The method will inevitably cause the overall center of gravity of the engine to shift to the flywheel side of the engine. However, since the engine crankshaft of the variable frequency generator usually does not need an independent power output terminal for connecting to the terminal equipment, the power output terminal refers to the other end of the crankshaft opposite to the flywheel end. In actual installation, the muffler of the engine can be arranged at the The direction of the engine c...
