Abstract

The invention discloses a spark plug for igniting an ignition-type engine. A sheet-shaped electrode is welded on a centre electrode; a ring-shaped electrode is embedded below the sheet-shaped electrode; and two side electrodes are arranged between the ring-shaped electrode and a metal shell. The spark plug provided by the invention can increase the ignition distance and the ignition energy without increasing high voltage, and therefore, the compressed combustible gas in the engine can be burned completely to ensure that the power of the engine is enhanced and the oil consumption and the exhaust gas are reduced.

Description

Ring-type is huge can spark plug

Technical field

The present invention relates to a kind of spark-ignition engine igniting and use spark plug.

Spark-ignition engine is the power source (its fuel can be gasoline, methanol gasoline, ethanol petrol, natural gas) of automobile, and spark plug is the heart of engine.The service behaviour that energy size that produces during plug ignition and the length of the duration of ignition directly have influence on engine.Ignition energy adds that greatly the duration of ignition is long, and the power of full combustion of fuel, engine must increase, and such on identical distance, fuel consumption must reduce, tail gas also can reduce.Like this on the power of automobile, can both obtain certain effect on the energy-conservation and exhaust emissions.

Background introduction

Spark plug as one of gasoline or the crucial igniting element of gas engine; Spark plug reliability at work will directly have influence on the dynamic property of engine, the economy of fuel oil and the discharging of tail gas, we can say that spark plug is gasoline or gas engine cardiac pacemaker.

The spark plug operation principle is: the direct current that the magneto that drives when automobile storage battery or engine running sends, to the ignition coil interruptedly supplying power, ignition coil provides high-tension electricity to spark plug through automobile computer ECU.Spark plug produces electric spark under the effect of high-tension electricity, light the imflammable gas through mixing, and blast workmanship promotion piston moves downward the drive bent axle and rotates.

The big young pathbreaker of energy during plug ignition directly influences engine performance: the discharging of power, oil consumption and tail gas.

Summary of the invention

The huge ability of ring-type of the present invention spark plug: be a kind of open type ignition spark plug, sparking mode is for being the open type igniting at work for it, and its ignition gap is big, energy big and longer duration.

Fig. 1 is common spark plug: this kind spark plug is at work because lateral electrode has absorbed quite a few energy (about 30%) in ignition process; Make ignition energy not enough; Cause imflammable gas fully not burn, engine power descends, the economy of fuel oil rises, exhaust emissions is bad.

Fig. 2 is the huge ability of ring-type spark plug: this kind spark plug is at work because igniting is the open type igniting; Imflammable gas is big with the flame contact-making surface in igniting; So imflammable gas fully burns, engine power rises, the economy of fuel oil descends, exhaust emissions descends.

Ring-type is huge can be reached more than the 2mm in the plug ignition gap, and common plug ignition gap is between the 0.65-1.2mm.

Spark fully contacts and does not have with imflammable gas and blocks during the huge ability of ring-type plug ignition, and spark is difficult for being able to guarantee by the reliability of the high pressure igniting that imflammable gas is blown out of warp compression.
