各位柴油車主 DPF(柴油碳粒濾清器) 第一次何時亮燈 ?

尿素添加系統的目的是要減少NOx的排放,其功能和EGR的設計是相同的.

DPF的添加劑又是另外一回事了.

在台灣銷售有DPF的TDI車種,DPF和三元觸媒轉換器是做在一起的,離引擎比較近,溫度比較高,DPF自清沒問題.
而早期台灣銷售的TDCi,DPF是單一元件,位置在三元觸媒轉換器的後面,離引擎比較遠,溫度會低個100度左右,無法僅靠引擎監理系統將DPF的溫度提升到DPF自清所需的600度以上,所以需要添加劑的幫忙使DPF自清.

TDI也是有需要加DPF添加劑的,只是台灣沒引進.

DPF添加劑
是長怎樣的?
使用時機何時呢?
作用是爲了??

原來DPF也有添加劑
請大大分享一下
謝謝

我購買的是這瓶 500ml , 1罐對應80L柴油

8000公里使用一次

原廠技師提供的方式是錯誤的
如果是 "KEEP" 在3000轉這時其實渦輪後排溫應該都只會在300度上下的低溫
如真要讓DPF自我清碳溫度在700度
開車的方式會變成用手動5檔或6檔(當然4檔也行只是升轉速快)低於2000~1500轉全油門讓轉速升到3500~4000轉,在這過程中排溫才會升高到700~850度以上
就算把轉速維持在4000轉持續幾十分鐘都一樣排溫不用5秒就只會降到300度左右
反覆的在那轉速區間升降才真的對清DPF有效果

G450 Sensor老化時也會讓DPF燈容易亮起
就算手動自我再生熄掉(但也是要用電腦讓G450重新判斷新的阻塞%才會熄掉)
這時不用開多久就一樣繼續亮燈

就是很多人對DPF及柴油系統並不懂,包含原廠也是
後來就很多車主花了不少錢車還是修不好或是被x廠說壞東壞西...
所以不少就便宜賣車
不過也因此我入手了一台Caddy Maxi肯定就是因為懶得修或被修了很多次吧
我把DPF功能關閉G450的線組接頭拔掉,就再也沒看到DPF燈亮了,系統也沒有故障
但DPF我並沒有拆掉因為這幾乎不會壞自己開車讓它恢復功能就好

目前VAG新的DPF若是沒常跑高速讓DPF再生,目前大約一段時間後,只要車子有啟動,在原地怠速也會自行啟動再生。

這也是錯誤的
單純原地怠速的溫度永遠是不足以讓DPF產生再生的能力
就是如此才會讓很多人的DPF一直都是問題
偶爾上路卡檔全油門在一個轉速區間開一開會較佳

而所謂的原地再生是要用電腦啟動原地再生選項
這時系統會自動提速
再生的過程及方式可以參考底下
1.6l/2.0l R4 CR-TDI

With the newer CR-TDI engines there are 2 different types of regenerations available depending on the actual soot mass/load. If either the calculated or measured soot mass is above 30g but below 40g you can initiate a regeneration while standing (Idle will be raised etc.), a forced regeneration while driving is also possible. Once the values are above 40g (but below the max 45g) the regeneration while standing is no longer available and the regeneration while driving is the only way.

Regeneration while Standing/Idle
Prerequisites (General):
Ignition ON
Engine ON (Idle)
Fuel Tank at least 1/4 full
Transmission in Neutral/Park
Parking Brake engaged
Coolant Temperature above 70 °C (see MVB 002.4)
Particle Filter Load below Specification (see MVB 108.2/3 -or- 241.2/3 VCDS should give the specified values)
If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.
Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)
Engine Hood Closed
[Select]
[01 - Engine]
[Security Access - 16]
Enter the Code shown by VCDS next to Adaptation Enabling (e.g. Regeneration while Standing)
[Do It!]
[Basic Settings - 04]
Select Block for Regeneration while Standing
[Go!]
Follow the Instructions on the Screen
[Done, Go Back]
[Meas. Blocks - 08]
Select Blocks 099 and 108 at once.
[Go!]
MVB 099.2: Exhaust Gas Temperature before Turbo Charger
MVB 099.3: Exhaust Gas Temperature before Particle Filter
MVB 099.4: Exhaust Gas Temperature after Particle Filter
MVB 108.2: Particle Filter Soot Mass (calculated) Alternate group 241.2 if 108 is blank
MVB 108.3: Particle Filter Soot Mass (measured) Alternate group 241.3 if 108 is blank
Now let the Car run with Raised Idle until the Particle Filter Load is as low as possible (close to 0 %).

[Done, Go Back]
[Close Controller, Go Back - 06]



而路上自我再生的方式
Regeneration while Driving
Prerequisites (General):
Ignition ON
Engine ON (Idle)
Coolant Temperature above 70 °C (see MVB 002.4)
Particle Filter Load below Specification (see MVB 108.2/3, VCDS should give the specified values)
If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.
If the Particle Filter Load value in MVB 108 is blank, use alternate group 241.2/3 instead.
Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)
Engine Hood Closed
Conditions (Driving Cycle):
Vehicle Speed above 60 km/h (40 MPH)
Engine Speed between 2000-2500 RPM (4th or 5th Gear, Automatic Transmission in Tiptronic)
Duration approx. 10-15 Minutes
Exhaust Gas Temperature before Turbo Charger above 170 °C (MVB 099.2)
Exhaust Gas Temperature before Diesel Particle Filter above 150 °C (MVB 099.3)
Exhaust Gas Temperature after Diesel Particle Filter above 150 °C (MVB 099.4)
Drive the car based on the above Conditions until the Particle Filter Load is as low as possible (close to 0 %). In case the Regeneration fails there can either be problems with the Driving Cycle Conditions or with the Engine Hardware.

[Select]
[01 - Engine]
[Security Access - 16]
Enter the Code shown by VCDS next to Adaptation Enabling (e.g. Regeneration while Driving)
[Do It!]
[Adaptation - 10]
Select Channel for Regeneration while Driving
[Read]
Enter/Save 1 as new Value.
[Save]
[Done, Go Back]
[Meas. Blocks - 08]
Select Blocks 099 and 108 at once.
[Go!]
MVB 099.2: Exhaust Gas Temperature before Turbo Charger
MVB 099.3: Exhaust Gas Temperature before Particle Filter
MVB 099.4: Exhaust Gas Temperature after Particle Filter
MVB 108.2 or 241.2: Particle Filter Soot Mass (calculated)
MVB 108.3 or 241.3: Particle Filter Soot Mass (measured)
Now Start the Driving Cycle and keep watching the Measuring Blocks (2nd Person required).
[Done, Go Back]
[Close Controller, Go Back - 06]
這時的重點與之前一樣如果KEEP維持在一個固定的轉速那應該也沒效果,最好還是把那一段改成切換到手動檔選高速檔位之一,從1500rpm左右全油門至3000或3500rpm,反覆的在這轉速區間升降

在新一點的CR-TDI使用以下的方式
Regeneration in CR-TDI Engines with UDS Control Modules
For engine controllers that use the UDS protocol (as shown on the top left corner of the Open Controller screen), no Security Access is needed.

Prerequisites (General):
Ignition ON
Engine ON (Idle)
Fuel Tank at least 1/4 full
Transmission in Neutral/Park
Coolant Temperature above 70 °C
Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)
Engine Hood Closed
[Select]
[01 - Engine]
[Basic Settings - 04]
Use the pulldown menu and select Service regeneration of particle filter
[Go!]
[Show Measuring Data]
It would be useful to select items such as "Particle filter, soot mass calculated", "Particle filter, soot mass measured", and "Particle filter, time since last regeneration" to observe and verify the progress of the regeneration.
Due to the way UDS works, there may be differences in the locations and specific description for the values so you may need to search for the values you need.
Follow the Instructions on the Screen. These may include pressing and/or holding the brake, clutch, or accelerator.
[Done, Go Back]
[Close Controller, Go Back - 06]

除了上路開外原地都是要使用電腦下指令才會自動做提速來再生
另外就是都要對G450 sensor做Coding或清除自我重新偵測的動作來確定

上路再生的方式對非VAG的車輛也是同樣的方式就有效果

P.S. 原地自我再生請找空曠有風處
我的G450壞的時候也是亮這個燈,偶爾還會動力跳脫,能修就盡快,拖越久越危險
小弟車子為 passat 2.0 TDI .. 2008年出廠,目前開了約 14萬公里,大約在十初頭萬 DPF 燈就開始偶而亮起,也是聽福斯建議高速開個十分鐘左右燈就熄滅,但後來愈來愈頻繁的出現,常常消不掉燈號就回福斯做手動再生,有幾次我上高速公司跑了快卅分鐘也消不掉,還多了一個螺旋狀的燈號出來,這個燈出現後,整個車子 turbo 馬上不見,只能低速行駛,每次問福斯原廠,給的答案都是做 DPF 再生即可,還說在歐洲都沒這個問題,不然就是說柴油車切忌走走停停及大腳油門,問到要如何徹底解決也都是支支吾吾沒給什麼答案,最後一次燈號差點消不掉,我在保養廠等著再生時,客服給了小弟一張報價單,要更換 DPF 裝置,連工帶料十幾萬,我看了傻眼,馬上謝謝再連絡,隔天把車賣了,換了一台汽油車。

後來上網看了一下相關資訊,發現柴油車是要固定時間清潔相關進氣管路及 DPF ... 在賣車前雖有花錢請坊間保養廠清潔,但狀況還是一 樣產生,這就是柴油車的宿命,發誓以後再也不碰柴油車了... 還有,柴油車渦輪因工作溫度較高,也會有提早報銷的可能性,小弟在清 DPF 時保養廠發現渦輪有損壞,後來花了一樣多修理,換新的聽說要四、五萬,本來以為買柴油車可以省油扭力又大,現在發現後續保養維修花費大,偶而大腳油門積碳又會更嚴重,真是賠了夫人又折兵,提供給還想買柴油車的朋友們做參考...

我的車也是2.0TDI ,目前12萬多公里, 引擎及DSG都很健康.

柴油車要常跑高速及快速公路比較適合. 平時路況順暢時以D檔行車,可以省油錢.

在上坡及超車時 ,可切S檔或M檔拉拉轉速提升引擎工作溫度, 引擎及噴油嘴才不容易積碳, DPF(柴油碳微粒濾清器)也不會阻塞.

常高速行駛, 3-5千公里後定時加柴油精清油路, 就不必擔心.

總之 ,柴油車不適合短程及低速的日常路況.

還有 保養要得法.引擎要適時拉高轉速跑一陣子, 不用擔心引擎大聲, 不能常在2000轉以下. VAG的TSI TDI引擎適合[高轉速 及高時速].

我是GOLFV 1.9TDI,之前要是一亮DPF燈,就得趁晚上開高速公路拉一下轉速,但是感覺效果沒有很好,一陣子之後又亮燈了,後來朋友介紹去一間專修VAG的保養廠,一接電腦才發現DPF阻塞已接近臨界值了,然後老闆幫我洗完,就像是鼻塞好了一樣,順!

清洗前已達臨界值


清洗後已經回復0%了
