He māmā ia e hoʻā i ka hui ʻana o ka ea/wahie.

Hana ia ma lalo o nā kūlana koʻikoʻi.

A Hoʻolālā ʻia lākou e unuhi i ka hana kiʻekiʻe loa mai ka ʻenekini a puni kona ʻano.

1. ʻO ia ka "ultra wide heat range" spark plug. Loaʻa iā ia kahi electrode waena me ke keleawe i hoʻokomo hohonu ʻia i ka piko e hoʻopau koke i ka nui o ka wela. Hana ʻia kēia i kahi pahu kukui me ka "ultra wide heat range" e kūʻē i ka wela nui a me ka hoʻoheheʻe ʻana.

Ke hoʻohālikelike ʻia nā hiʻohiʻona wela o nā pahu ahi me ka ʻole o nā ʻāpana keleawe, ʻoi aku ka maikaʻi o nā pulupulu me nā ʻāpana keleawe i ka wela a me ka pale ʻana a hāʻawi i kahi laulā hana wela.

2. Hoʻokomo ʻia kēia pahu kukui i kahi insulator i hana ʻia me nā seramika alumina kiʻekiʻe.

• Loaʻa iā ia ka insulation ʻoi aku ka maikaʻi ma nā wela kiʻekiʻe a hāʻawi mau i ka sparking.

• Hāʻawi ia i ka conductivity thermal maikaʻi a pale i ka overheating.

• Kūpaʻa ia i ka pihoihoi wela a hāʻawi i ka ikaika mīkini kiʻekiʻe.

3.It kahi paʻa paʻa e hōʻoia i ka paʻa o ke kinoea.

Kaʻina hana crimping wela kūikawā e hōʻoia i ka ʻoi aku ka maikaʻi o ke kinoea a me ke kūkulu ikaika.

4.ʻO ka piko electrode i hanaʻia me ka nickel alloy kūikawā e hōʻoia i ka lōʻihi o ka lōʻihi.

ʻO ke kinikini nickel kūikawā e hōʻoia i ke kūpaʻa o ka wela kiʻekiʻe a me ka lōʻihi.

Pono e hoʻopau ka pahu ahi i ka wela i hana ʻia e nā kinoea puhi. ʻO ka helu wela he ana o ka nui o ka wela.

Pono ka hoʻohana ʻana i kahi pahu kukui me ka helu wela e pili ana i kahi ʻenekini kikoʻī a me kona kūlana hoʻohana.

Ke koho ʻia kahi helu helu hewa hewa,

Ke kiʻekiʻe loa ka helu helu wela,

Noho haʻahaʻa loa ka mahana o ka pākuʻi ahi a hoʻoulu i nā waihona ma ka hopena kī; Hāʻawi nā waihona i kahi ala leaka uila e hiki ai ke kumu hewa.

Ke haʻahaʻa loa ka helu helu wela,

Piʻi kiʻekiʻe loa ka wela o ka pulupulu a hoʻoulu i ka hoʻopau ʻana (pre-ignition); alakaʻi kēia i ka hoʻoheheʻe ʻana i nā electrodes plug spark plug i hiki ke hoʻopilikia e like me ka pōʻino piston.

A ʻO nā helu ʻāpana TORCH ke kumu no ke koho ʻana i ka pahu kukui i kuhikuhi ʻia e ka mea hana.

A No ka mea, e hōʻike ana ka hiʻohiʻona o ka hopena o ke ahi i ke kūpono o ka pahu kukui a me ke ʻano o ka ʻenekini.

A Hoʻopaʻa lākou i ka pale a pale i ka flash-ove

He aha ka flash-over?

ʻO ka Flash-over ka wā e loaʻa ai ka ʻula ma waena o ka pahu a me ka pūpū metala, e like me ka mea i hōʻike ʻia ma ke kiʻi.

Hiki ke pale ʻia ʻo Flash-over e ka mea aʻe.

Hāʻawi ʻia nā iwi ʻaoʻao ma ka insulator e hoʻonui i ka mamao o ka insulator ma waena o ka pahu a me ka pūpū metala. Mālama kēia i ka insulation e pono ai no ka pale ʻana i ka flash-over.

Hiki ke mālama ʻia ka huna ahi pololei e ka hakahaka hunaahi.

A It is not a stain caused by gas leakage but by corona discharge (corona stain).

When a spark plug is removed, a brownish stain that looks like a sign of combustion gas flow is often seen at the crimping portion of the metal shell.

This stain is the result of oil particles suspended in air adhering to the surface of the insulator due to the high voltage. It does not affect spark plug performance.

Pāpā Corona

Mechanism of corona discharge The high voltage applied to the spark gap is also applied to the area between the center electrode and the metal shell, causing an insulation breakdown of the air at the gap (a) between the insulator and the metal shell. The phenomenon is called a corona discharge. The generated corona discharge develops toward the terminal nut. This last process is the pale blue corona discharge that may be observed in dark conditions.

Q15 He maile iki wahi kikoʻī i hoʻopili ʻia no ka plug plug

A The tightening torque for a spark plug changes with the diameter of the spark plug.

ʻO nā huaʻōlelo i hōʻike ʻia i nā waiwai o ka torea i ʻōlelo ʻia.

When installing the spark plug, first screw it in by hand. Once the gasket has made contact with the cylinder head, use the torque wrench to tighten it to the tightening torque shown below.

A rubber pipe as shown in the figure to the right is a good substitute for hand

paʻa / kāpae i nā plug plug.

Noho ʻano noho kūmole no (spark plugs me nā wahi ʻole)

The tightening angle for both new and reused spark plugs is 1/16th of a turn.

Nā hiʻohiʻona o nā pilikia hoʻolaʻa maʻamau a me nā ʻōlelo aʻo e pale iā lākou.

A E hōʻoia i ka loaʻa pono o ka ipo huna.

ʻAʻole e holo pono ka ʻenekini me ka ʻole o ke kiko o ka pae.

If a spark plug with the wrong thread length is erroneously used, the piston or valve could strike it and damage the engine. Moreover, there is also the concern that the electrode could overheat and melt.

A E ʻike pono i nā huna huna i nā ana hoʻohālikelike kūpono.

Nui a hewahewa nā ʻano o nā momoku ahi.

Sometimes, even when the length of the thread is correct, installing a spark plug with long metal shell projection dimensions may cause it to be struck by the piston or valve and result in engine trouble. Only use projection type plugs as specified by the manufacturer.

When trying to remove a spark plug that is tight and will not come out easily, removing it by force may damage the neck of the threaded section and break the seal section of the spark plug, causing the threaded section to remain in the cylinder head.

To remove such a spark plug without excessive force, first operate the engine and allow it to warm up the cylinder head, then apply penetrating oil to the threaded section.

Ma hope o kahi manawa pōkole, hiki ke hoʻoneʻe i ka huna ahi.

A Even when a spark plug is correctly used, periodic replacement is required as it is a consumable item.

Examples of problems caused by excessively long periods of use: Worn-out electrodes will have difficulty in sparking.

Deposits accumulated on the firing end may induce abnormal combustion, causing problems that include melting of the electrodes or damaging engine.

These spark plugs require replacement.

It must be noted that these phenomena may also be caused by inadequate engine servicing (fuel systems and ignition system) and incorrect spark plug selection.
