Engine ventilating device

Abstract

The invention relates to an engine breather for improving the performance of a whole internal-combustion engine and being favorable for environmental protection. The invention is characterized in that a cylinder cover is provided with a plurality of shutters and separation chambers filled with catch materials and covered by an inspirator cover. The inspirator cover is provided with an oil-gathering groove. The bottom of the oil-gathering groove is provided with a plurality of oil drain holes. The inspirator cover is provided with an inspirator pore that is a communication pore canal for a crankcase and an intake manifold. An inspirator spring piece and a spring piece binder plate are arranged in the inspirator pore. The engine breather can prevent oil mist in the crankcase of the engine from being discharged to outside, thus effectively stopping elaioplast in the oil mist from entering a combustion chamber and avoiding carbon and cold smoke caused by the oil burning of the engine. And the engine oil consumption and the discharge amount of carbon granule are increased.

Description

technical field [0001] The invention relates to a ventilation device for an engine crankcase to improve the performance of the entire internal combustion engine and be beneficial to environmental protection. Background technique [0002] In the prior art, the ventilation device of the crankcase of the engine is relatively simple. Usually, a steel wire filter screen is installed on the oil filler cap cover, and some small holes communicate with the atmosphere. Some also have a small hole at the highest point of the cylinder cover. The rubber tube communicates with the outside world, so that the oil mist gas in the crankcase can directly communicate with the atmosphere, but this kind of structure is easy to pollute the air around the engine, and oil droplets will form sludge on the ground. In addition, there is also a rubber diaphragm valve installed at the highest point in the cylinder head cover to allow the outlet gas to flow into the intake pipe, and the oil gas contains m...

[0002] In the prior art, the ventilation device of the crankcase of the engine is relatively simple. Usually, a steel wire filter screen is installed on the oil filler cap cover, and some small holes communicate with the atmosphere, and some have a small hole at the highest point of the cylinder cover. The rubber tube communicates with the outside world, so that the oil mist gas in the crankcase can directly communicate with the atmosphere, but this structure is easy to pollute the air around the engine, and oil droplets will form sludge on the ground

In addition, there is also a rubber diaphragm valve installed at the highest point in the cylinder head cover to allow the outlet gas to flow into the intake pipe, and the oil gas contains more oil particles, which burn after entering the cylinder, which will easily cause the engine to burn oil, high oil consumption, Blue smoke from the exhaust, resulting in carbon deposit failures in cylinders, pistons, piston rings, fuel injectors and valves
