Embodiment Construction

[0024] A specific embodiment of an internal combustion engine of the present invention is given below in conjunction with the accompanying drawings.

[0025] figure 1 It is a sectional view of a cylinder head of an internal combustion engine according to the present invention, please refer to figure 1 shown. Including a plurality of cylinders, there is also a swirl chamber 1 with an intake passage 2 connected to the main combustion chamber 3 with a pre-combustion chamber and meets the The cross section 5 of the prechamber, the intake channel 2 to the piston 6 of the internal combustion engine has a rounded corner, the intake channel 2 has a central axis and extends through the central plane of the prechamber. A main combustion chamber 3 with piston 6 and cylinder passages 4 together with cylinder head 7, while the main combustion chamber 3 is connected to each cylinder. The cylinder head section is shown in section and the pre-chamber is also arranged inside. In addition, ...

Abstract

The invention discloses an internal combustion engine, which comprises a plurality of air cylinders, a fuel oil injection system and a glowing ignition device, wherein each air cylinder is provided with a main combustion chamber and a precombustion chamber, and an air inlet passage for being introduced into the precombustion chamber; and one to two projected rod-shaped components arranged inside each precombustion chamber are deeply arranged in the precombustion chamber so that the rod-shaped components are arranged outside an opening of each air inlet passage of each precombustion chamber and extend to a marginal area in the injection range of the fuel oil injection system. According to the application of the internal combustion engine, through non-tangential contact between the ignition device and an oil beam, the risks caused by too large distance between the oil beam and the ignition device are effectively avoided, and meanwhile too much heating load of the ignition device is also eliminated. Meanwhile, the deviation with each other is effectively counteracted through the arrangement of the ignition device, and the deviation of the oil beam to a central plane longitudinally is convenient to detect as the direction of the oil beam to the central plane and the edge range of the oil beam are considered.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to the technical field of internal combustion engines. Background technique [0002] As everyone knows, an internal combustion engine utilizes a blazing ignition device that is composed of a rod-shaped spark plug and is installed in a spherical vortex chamber at a certain angle to ignite fuel. After fuel injection, the air flowing through the intake passage and the air flow direction that has formed the central swirl layer flows into the swirl chamber. The internal combustion engine ignites the spark plug at the best timing when the spark plug is installed and embedded in the cylinder by changing the depth of the spark plug relative to the fuel injection trajectory. The central axis of the spark plug lies parallel to the plane of symmetry of the swirl chamber and extends through the fuel flow and the point where the spark plug tip terminates, which is the optimum point...
