A method of improving engine compression efficiency and saving fuel

Abstract

The invention discloses a method combining an oxygen sensor improved structure and a surface ceramic recombination metal wear self-repair technology for improving engine compression efficiency and saving fuel oil. An aeration area of an oxygen sensor is reduced to 3-30% of an original aeration area by the oxygen sensor improved structure, the oxygen content in the exhaust gas detected by the oxygen sensor is lower than the actual content, and thus a deception signal is sent to an ECU, being in a rich oil state is received by an oil injection control module by mistake, and thus the oil injection quantity is reduced. The surface ceramic recombination metal wear self-repair technology enhances the cylinder pressure by 20-45%, the compression efficiency is improved, and an ideal oil-gas mixture ratio ignition mode of a traditional gasoline engine is enabled to qualitative change to a high compression ratio and rare oil-gas mixture ratio ignition pressure explosion type combustion mode. According to the method, an ignition combustion engine does not need to change hardware manufactured by an original vehicle factory and electronic control software, a rare oil-gas mixture ratio and highcylinder pressure ignition pressure explosion combustion mode is achieved, the fuel oil is saved, the power is improved, the exhaust emission is reduced, and the vehicle environmental protection standard is improved.

Description

technical field [0001] The invention relates to the improvement of engine combustion efficiency, power output performance and emission environmental standards, and in particular relates to an improved structure of an oxygen sensor and a method for improving engine compression efficiency and saving fuel. Background technique [0002] The compression ratio is an important technical parameter of the engine. Only by maintaining a stable and proper compression ratio can the engine run smoothly and stably. The compression ratio is determined by the physical size of the automobile engine when it is designed and manufactured. After the engine structure is determined, its compression ratio is constant. [0003] During the operation of the engine, the friction between the inner wall of the cylinder and the piston ring will cause wear and tear, and the gap between the friction surfaces will increase, and gas leakage will occur, resulting in a decrease in the suction efficiency of the e...
