2011 Accent AT - Engine Knock!

[jayvel]

pabor din ako sa eb, para macompare natin ang mga units kung pare pareho tayo ng issue

[tudor]

Sa mga Hyundai Accent owners, natry nyo po ba irecord ang sound? Marami po sa youtube na engine noise pero mga old Accent yun. Kasi sa mga baguhan na katulad ko, di ko po alam ano tunog ng engine knock. hehe. Kasi yung Nissan namin kahit old na wala po siyang tunog na kakaiba. And since luma na po iyun, wala po kaming point of reference (for comparison). Thanks.

^ It's hard to determine the "knocking" sound sa video lang.

Mas maganda actual, IMO.

may mga sure na ba ppunta sa EB sa 24? I'm willing na pa drive test ung unit ko dun for comparison. We can PM our contacts para mas madali tyo maka pag meet up.

Ako willing pumunta, sana lang ma free schedule ko by then.

Had an early morning drive kanina. Sarap talaga pag early sunday mornings walang traffic. Sinubukan kong hatawin for the first time para matanggal mga carbon deposits. First time ko rin napaabot ng 4k plus rpm hehehe. Lakas talaga humatak kahit 1.4 lang. Kaso nung nag menor menor nako and papitik pitik lang sa accelerator ayun meron pa palang engine knock. Sa higher rpms wala siyang knocking. So na conclude ko na talaga na hindi nga gasoline ang problem kungdi ecu timing at low rpm may diprensya. Nung pauwi na nag radio nalang ako para hindi mairita hehhe

punta rin ako

*bratski, jayvel - I sent you a PM with my contact no. Let's get in touch na lang sa 24 kung what time kyo mkkapunta. Thanks!

i think maganda ang combination natin ni bratski and jayr, Si bratski, hindi pa nagpaupdate ng ecu pero me engine knock, si jayr nagpaupdate pero umokey na, ako naman, dalawang update nawala yung engine knock, pero nag lolow power. Talagang macocompare natin ang situation ng isat isa

Guys I tested an accent kahapon na may knocking, and we swapped rides para nga maconfirm yong observations namin.

And obviously, wala yong sa akin, while sa kanya, noticeable yong knocking sound when the engine is between 1500 - 2000RPM, the time when the tranny shifts from 2nd to 3rd. But when it surpasses 2000RPM, mawawala na yong knocking sound.

I noticed when I tried shutting down the AirCon, yong knocking sound is gone. Yong unit na natest ko kahapon, parang hirap yong accent at those RPM. Pansin ko yata, parang CVT ang problemang to. Hirap ang makina when the tranny is in transition to change gear from 2nd to 3rd or di kaya when your at lower steady phase. But when you depress the gas pedal, giving the engine a good amount of fuel, eh nawawala yong knocking sound. Napansin ko rin, na kahit hatawin mo yong sasakyan, lalabas at lalabas pa rin in the mid 1500-2000RPM yong knock.

Someone mentioned about RIo's gamma engines. Ang problema kasi with RIO, hindi naka CVT, kaya malamang in-existent tong problemang to sa kanila.

Aside from ECU Remapping, we might also consider suggesting to look at the possibilities of reprogramming the CVT.

And one thing pala, yong unit ko only refills gas on only one shell station, plus ang sa akin, I sometimes mixed my fuel type from super unleaded to V-power on full tank basis. Yong sa kanya raw, Petron unleaded.

I'll try filling up this week for an XCS or unleaded para ma-obserbahan ng husto.

Tama, lumalabas yung knocking pag transition ng 2nd to 3rd gear and rpm is 1500-2000. Above 2000rpm wala talagang knocking. Hirap siguro mag adjust yung ecu. Try mo at 3rd gear then rpm at 1500. Tapos pitik pitik ka sa gas, tuloy tuloy knocking nyan.

Yung a/t transmission ng accent is not cvt. Conventional 4 speed auto lang siya. Yung engine natin ang cvvt which stands for continuosly variable valve timing.

Yung sa kia rio tiningnan ko specs sa website nila. Although same gamma 1.4 engine, mas lower ang power output niya. 94hp versus 108hp sa accent. Baka engine ng rio iba ang ecu mapping kaya lower power but no knock
