Broad sense crankcase oil tray for motorboat engine

Abstract

The invention discloses a generalized crankcase oil tray of a motorboat engine. The generalized crankcase oil tray is provided with an inner-layer shell body, an outer-layer shell body, an oil inlet pipe joint, an oil outlet pipe joint, a water inlet pipe joint, a water outlet pipe joint, an oil drain plug seat, an oil drain plug screw, an oil filling port seat and an oil filling port cover; engine oil is stored in the inner-layer shell body; cooling water flows in a jacket between the inner-layer shell body and the outer-layer shell body. The application of the generalized crankcase oil tray reduces both the height of the dry-type crankcase oil tray of the motorboat engine and the gravity of the motorboat engine, so that the whole motorboat has better dynamic property; the middle space of the motorboat is utilized to get the operations of the engine oil filling, the engine oil draining, the observation of the lube level height, etc. more convenient.

Description

Technical field [0001] The present invention relates to a structure of an engine. More specifically, the present invention relates to a generalized oil pan structure of a motorboat engine. Background technique [0002] The oil pan is mainly used to store lubricating oil. The volume is generally above 4L. The oil volume must fill the entire system and wet the cylinder walls and parts, and it must also compensate for the oil loss during the engine refueling period. The volume is relatively large. The oil sump has very little force and is generally stamped with thin steel plates. Some of the oil sumps of engines are made of aluminum and are made of casting. Its shape depends on the overall layout of the engine and the oil capacity. An oil stabilizing baffle is installed in the oil pan to prevent excessive fluctuations in the oil level when the car moves. The structure is relatively complicated, which increases the height of the engine. [0003] When the engine is running, the high-p...

AI Technical Summary

Problems solved by technology

When the amount is small, it will be suspended in the oil, and when the amount is large, it will be precipitated from the oil, blocking the filter and oil hole, making it difficult to lubricate the engine and causing wear and tear

In addition, when the engine oil oxidizes at high temperature, it will form a paint film and carbon deposits to stick to the piston, which will increase the fuel consumption of the engine and reduce the power. In severe cases, the piston ring will be stuck and the cylinder will be pulled.
