Description

Mars plug structure

This creation is about a Mars plug structure that is simple in structure and can effectively improve ignition efficiency.

Common cars and motorcycles use a gasoline engine, and the gasoline engine must use a spark plug to ignite the gasoline to burn. The more efficient the combustion, the more the engine's performance can be played, so the correct use of the spark plug is very important. In general, the main function of the Mars plug is to generate a spark to ignite the compressed oil-gas mixture, causing it to explode and push the piston. Therefore, the engine must be operated to drive a continuous high-voltage electric pulse into the electrode of the spark plug. The discharge ignites to ignite the mixture within the cylinder to create the energy required to provide the engine's power output.

The principle of sparking a conventional Mars plug is to ignite using the physical principles of high-voltage electric point discharge. Therefore, in the past, the design of the Mars plug, almost regardless of the design style, almost only set a fixed ignition gap. As shown in Fig. 3, a conventional spark plug a is provided with a center electrode c (positive electrode) which is covered by a ceramic insulator b and whose one end is convex upward, and the outer side of the ceramic insulator b is An iron shell d is surrounded, and a top electrode e (negative electrode) extends upward from the top end of the iron shell d, and an ignition gap (not shown) is provided between the side electrode e and the center electrode c. When the high voltage electricity passes through the spark plug a, a current is discharged from the center electrode c to the side electrode e, and a high voltage electric spark is generated to jump the ignition gap to ignite the mixed gas in the combustion chamber (not shown).

However, the size of the ignition gap has a great influence on the performance of the spark plug. When the gap is improperly adjusted (different lengths), the number of spark plugs is 2%, and the driver does not notice that the car is not normal. However, the amount of hydrocarbons emitted by the exhaust gas is about doubled, which not only causes air pollution, but also wastes gasoline fuel.

Therefore, how to improve the existing Mars plug to reduce the occurrence of sparks and sparks to reduce the problem of ignition failure has always been the direction of the creators.

The main purpose of this creation is to provide a Mars plug structure that is simple in structure and can effectively improve ignition efficiency.

For the above purposes, the present invention provides a Mars plug structure having a body having a housing at one end and having a thread thereon for tightly screwing onto a cylinder head of an engine, the improvement being: The outer casing of one end of the body is covered with a central electrode, and three grounded negative electrodes are arranged at equal intervals around the central electrode. The grounded negative electrodes are in an inverted L shape, and the ends are oriented toward the central electrode and are tapered to form a tip. End face.

When implemented, the pointed end faces have a polygonal shape.
