Hiki ke pi'i koke ke pi'i ka wikiwiki o ka enekini i 3000 rpm.

Phenomenon: Hōʻike nā mea kūʻai i ka piʻi pinepine ʻana o nā kaʻa, a i kēlā me kēia manawa ke piʻi ʻana, kokoke like ka throttle (accelerator pedal), a i ka manawa like, piʻi ka hoʻohana ʻana i ka wahie a emi ka mana.

Kānāwai:

1. Ua hewa ke kūlana throttle.

2. Ua hewa ka crankshaft position sensor a pa'a ole ka hoailona.

3, ignition system hemahema, ka hopena i ka nele o ke ahi i ka coincidence.

4. ʻAʻole kūpono ʻole o ka flowmeter ea

ʻIkepili:

1. Kāhea i ka helu hewa, e hōʻike ana he ʻilihune ka ratio hui ʻana.Hiki ke hoʻomaopopo ʻia e pili ana ka hewa i ka wehe ʻana o ka throttle.Ke hoʻohana nei i ka oscilloscope e ʻike i ke kūlana throttle, hōʻike ia i kona ʻano nalu e hōʻike ana i kahi ʻano haʻahaʻa haʻahaʻa me ka piʻi ʻana o ka wehe ʻana o ka throttle, a maʻalahi kona ʻano a me ka burr-free, e hōʻike ana he mea maʻamau ke kūlana throttle.

2. Ma muli o kekahi hanana hewa ʻē aʻe, piʻi ka hoʻohana ʻana i ka wahie a emi ka mana.Ua ho'āʻoʻia ka mika kahe o ka ea a me kaʻike oxygen, aʻo ka nui o ka ea kahe o ka ea he 4.8g / s i ka wikiwikiʻole, a ua hōʻikeʻia ka voltage hōʻailona o kaʻike oxygen ma kahi o 0.8V.No ka hōʻoia ʻana i ka maikaʻi o O2S, ua hoʻomaka ka ʻenekini e hoʻopau i ka wikiwiki ma hope o ka huki ʻana i kahi paipu hāmama ma ka intake manifold, a ua emi ka hōʻailona o O2S mai 0.8V a i 0.2V, e hōʻike ana he mea maʻamau.Eia nō naʻe, i ka wā o ka hana ʻana, ua hoʻomau ke kahe ʻana o ka ea i kahi amplitude liʻiliʻi o 4.8g/s.Ma hope o ka wehe ʻana i ka plug o ka mika kahe o ka ea, ua hoʻomaka hou ka hoʻāʻo, a nalowale ka hewa.Hoʻoponopono pilikia ma hope o ka hoʻololi ʻana i ka mīkini kahe ea.

Hōʻuluʻulu manaʻo:

Ke manaʻo ʻia he hewa ka mea ʻike, hiki ke hoʻohana ʻia ke ʻano o ka wehe ʻana i ka plug sensor (ʻaʻole hiki ke wehe ʻia ka mea ʻike kūlana crankshaft, inā ʻaʻole hiki ke hoʻomaka ke kaʻa) hiki ke hoʻohana no ka hoʻāʻo.Ke wehe ʻia kahi plug, e komo ka mana o ka ECU i ka papahana standby a hoʻololi ʻia e nā waiwai hōʻailona i mālama ʻia a i ʻole.Inā nalowale ka hewa ma hope o ka wehe ʻana, ʻo ia ka mea pili ka hewa i ka sensor.
