An all-aluminum engine cylinder inner wall ceramic fixture

Abstract

The invention provides an all-aluminum engine cylinder inner wall ceramic fixture. The all-aluminum engine cylinder inner wall ceramic fixture comprises a reaction part and a liquid inlet part; the reaction part comprises a cathode column, and a cathode fixed cover for fixing the cathode column at one end of a cylinder cover; a liquid drainage hole axially extending is formed in one end, positioned out of a cylinder body, of the cathode column; a liquid inlet hole communicating with the liquid drainage hole is formed in a column body, extending in the cylinder body, of the cathode column; the liquid inlet part comprises a liquid inlet column mounted at one end of a cylinder crank, and a liquid inlet fixed cover for fixing the liquid inlet column at one end of the cylinder crank; the liquid inlet column and the internal of the cylinder body are tightly contacted; and a through channel is formed in the axial direction of the liquid inlet column. The all-aluminum engine cylinder inner wall ceramic fixture adopts overall engine positioning; and the reaction range in the cylinder body is positioned by the cathode column, so that reaction liquid is locally contacted with an engine (only contacted with the inner wall of the cylinder body), and total ceramic inner wall of the cylinder body is realized. Reacted liquid can be timely drained through a liquid drainage mode from bottom to top, and meanwhile, heat in the cylinder body is taken away, so that the reaction temperature in the cylinder body is kept at the room temperature.

Description

technical field [0001] The invention relates to the field of engines, in particular to a fixture used for ceramicizing the inner wall of an all-aluminum engine cylinder. Background technique [0002] The development of high-efficiency and energy-saving vehicles has become the focus of the country's energy-saving and emission reduction. Alloy engine has become the focus of development because of its excellent performance. For every 10% reduction in vehicle weight, fuel consumption can be reduced by 6% to 8%. All-aluminum engines are being developed at home and abroad, but their disadvantages are that the friction coefficient is large and the wear and fuel corrosion problems are serious. In order to meet the requirements of industrial use, the so-called all-aluminum engines at home and abroad must be inlaid with cast iron cylinder liners inside the cylinder block, but The cast iron cylinder liner is heavy, and it is difficult to meet the requirements of a real all-aluminum e...

AI Technical Summary

Problems solved by technology

However, the automobile engine itself is a workpiece with complex design and multi-curved surfaces. In addition, it is not a symmetrical workpiece, so it is difficult to find a suitable positioning point in the process of ceramicizing the interior of the cylinder.

As for the production requirement of ceramicizing the inner wall of the cylinder, it must be ensured that only the inner wall of the cylinder can contact the ceramic working fluid, and the ordinary production method of completely immersing in the working fluid cannot meet the requirements
