Embodiment Construction

[0023] exist Picture 1-1 Middle: The intake port (1) divides the air entering the cylinder. When the air passing through the intake passage (13) passes through the fuel injection pipe (2), it mixes with the injected fuel to form a fuel mixture flow, which flows from near the spark plug One side enters the cylinder; in addition, the air passing through the intake passage (14) is not mixed with the fuel, and forms a convection flow with the fuel mixture flow in the cylinder, and the suction force generated by the piston movement guides the flow direction of the airflow. Respective backflows are formed, and the fuel mixture gas flow gathers around the spark plug (6), which is easy to ignite and burn, thereby ensuring that the fuel mixture gas can be ignited and burned in a short time; the flow rate of gas entering the cylinder can be adjusted and changed through the throttle valve (12) The ratio of air and mixed gas in the cylinder maximizes the air-fuel ratio of the gas in the c...

Abstract

The invention relates to a lean burn engine. Gas entering a cylinder is split and the flow direction of gas flow is controlled, so that part of air entering the cylinder cannot be sufficiently mixed with fuel; the fuel concentration of the gas at each part in the cylinder is different; and the fuel concentration of the gas close to a spark plug (1) is relatively high, so that the gas close to the spark plug (1) is easy to ignite to cause stratified combustion so as to fulfill the aim of lean combustion.

Description

Technical field: [0001] The invention relates to an energy-saving engine, which saves gasoline consumption of automobiles through lean combustion, thereby achieving fuel saving and reducing harmful gas emissions, greatly slowing down human energy consumption and reducing environmental pollution. Background technique: [0002] Energy is the material basis of human activities. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technologies. In today's world, the development of energy, energy and the environment are issues of common concern to the whole world and all mankind. [0003] According to the general estimates of economists and scientists, by the middle of this century, that is, around 2050, oil resources will be exhausted, and its price will rise to a high level, which is not suitable for popular application. If the new energy system has not Established, the energy crisis will sweep th...
