Tips on how to Restore Jetta Diesel Black Smoke Trouble With OBD2 Device
Description with the problem
Jetta diesel engine black smoke
Trigger
1. cylinder pressure is lower
2
. improper adjustment of start out of injection
3. Failing maintenance, utilization of non-original spare elements
4 Use of poor top quality diesel
Distribution
Jetta diesel automobiles
Technical Note
Cylinder strain
OBD2 verify problem: Engine temperature is greater than 30 ??
obd ソフトOBD2 Inspection steps: Clear away the upper consumption manifold
Disconnect the fuel pump shut-off valve plug
Disconnect the fuel pump fuel regulator plug
Eliminate the glow plug with socket 3220
The connecting rod screwed to the glow plug place VAG1381/12
Strain measuring cylinder strain tester VAG1763
Strain standard: the new engine: 25 ~ 31bar
Wear restrict: 19bar
Each cylinder tolerance: 5bar
Probable explanation for your low cylinder stress:
1 engine valve closed lax
two piston ring counterparts
three engine inlet, leading to the piston rod bends
4 severe engine put on
Start out of injection adjustment
Regular array: 50 ~ 60
Go through data: Engine management unit 000 display group second set of data adjustment process:
one, the fuel pump and pulley bolts -1 - Loosen, but don't unscrew.
two, by adjusting the fuel injection pump and the relative position of the pulley, modify the injection get started stage.
Left = delay adjustment
Suitable tone = early
Note: Alter the get started of injection to the engine control unit 000 combines information from a number of actions to complete.
About Diesel
Diesel needs:
1, the use from the petrochemical, oil and clean diesel with obd benz vogt
2, in accordance towards the necessity to utilize the authentic diesel fuel additive (portion number: LN 052 FVW 00).
Tips on how to use: Use a can of additive per tank in accordance with all the criteria
Constant vehicle with 6 cans
After each and every ten,000 km constant use three cans
Note: Each time you use diesel fuel additives, diesel fuel and additives to make certain thorough mixing of
Harm triggered through the use of inferior diesel:
1, low-quality diesel fuel can't guarantee normal combustion, could cause:
1) incomplete combustion exhaust black smoke
2) ash increases the oxidation catalytic converter plug
3) long-term use, resulting in fuel adjustment isn't normal, the electronic handle unit will exist N146 regulator failure (this failure is often eliminated through the utilization of certified diesel automatic).
4) Considering that coke fuel recirculation mechanism creating serious back position is terrible, the engine is just not doing work effectively, resulting in the phenomenon of black smoke.
5) Since coke resulting in serious fuel injector is just not doing work correctly, this time without the must use a clean cloth to clean the lint injectors, pay attention to not use any gadget or injector cleansing agent.
2, diesel sulfur material is too large, will make the combustion chamber, piston crown and exhaust valves and various elements of serious coke.
3, contains quite a bit of water, in order that fuel pump serious corrosion.
4, mechanical put on enhance, reduce engine daily life. 2, according on the needs and timely water.
3, focus to user maintenance records to make certain that end users necessary upkeep of diesel autos.
Emphasizes using high-quality creadervi and diesel additives necessity
Use original spare parts. Smoky diesel autos encountering challenges, stick to these actions:
1, OBD2 inspection and maintenance data, some factors clear
use diesel fuel additive in accordance with specs
no matter if to implement authentic spare components
whether the necessity for upkeep mileage
2, to verify whether or not the consumer the use of clean diesel
3, OBD2 check the injector beginning point
4, OBD2 check the cylinder cylinder pressure
OBD2 verify the injector, exhaust gas recirculation, oxidation catalytic converter is faulty
