Smoke belching ng LTO WTF is this

[renzo_d10]

Dun sila sa EDSA, yellow lanes to be exact. Tignan ko kung wala silang makitang huhulihin dun. :hysterical:

Alangya, wala pang 30 minutes, makakarami na sila ...

[kurby]

Dito sa Laspiñas LTO nirerev ang engine kahit motor or sasakyan mapa diesel or gasoline rev lang ng rev. nung pag pa test ng lolo ko doon binatukan yung nag tetest. sabi sisirain mo sasakyan namin paabutin ba naman ng 8000rpm. nabatukan tuloy. tapos lipat kami sa LTO Parañaque

ANNEX "B"
EMISSION TEST PROCEDURE FOR REGISTERED OR IN-USE MOTOR VEHICLES EQUIPPED WITH SPARK-IGNITION ENGINES (Gasoline Engines)

1. Scope
The test procedure is for the determination of the concentration of exhaust carbon monoxide (CO) and hydrocarbon (HC) emissions from in-use motor vehicles equipped with spark-ignition engines running at idle speed.

2. Test Equipment (Reference: ISO - 3930)

a. Carbon monoxide analyzer - a NDIR (Non-dispersive Infrared) CO exhaust gas analyzer.

b. Hydrocarbon analyzer - a NDIR HC exhaust gas analyzer, HC as hexane (C6H14).

c. Tachometer - An easily installed and operated tachometer to measure engine speed (RPM).

3. Vehicle Preparation
d. Set the vehicle transmission at neutral with the hand-brake engaged.

e. Ensure that the idling speed or the engine rpm with the accelerator in the rest position, conforms with the vehicle manufacturer's recommendation.

f. All accessories like rear window heating, air conditioning system, air fan and other equipment necessary for the vehicle operation at idle should be switched-off.

g. Check that the temperature of the engine is at least 70oC; otherwise, run the vehicle for at least 15 minutes on a normal road before testing.

h. Ensure that the vehicle exhaust system is reasonably leakproof and will allow the insertion of the sampling probe by at least 30 cm. from the tailpipe outlet. If this is not possible due to tailpipe configuration, use the appropriate correction factor.

4. Measurement

a. Immediately preceding the measurement, adjust the instrument to zero and accelerate the engine to about 2,500 rpm, using the tachometer, if available. Maintain this speed from ten (10) to fifteen (15) seconds, then release the pedal to return the engine at idle speed.

b. While the engine idles, insert the sampling probe into the exhaust pipe as deeply as possible which shall not be less than thirty (30) cm. Wait for twenty (20) seconds and take the CO/HC reading.

c. If the vehicle has multiple exhaust outlets the arithmetic average of the CO/HC readings in each exhaust outlet is taken as the final result.

5. Instrument Calibration, Adjustments (Reference: ISO 3929)

(a) Prepare, use and maintain the analyzer following the directions given in the instrument manufacturer's operation manual and service the instrument at such intervals as to ensure accuracy.

(b) Carry out a span and zero calibration within a period of four (4) hours before the instrument is moved or transferred to a new location. The calibration shall be performed well away from the exhaust of motor vehicles whose engines are running.

If the instrument is not self-compensated for non-standard conditions of altitude and ambient temperature or not equipped with a manually controlled system of compensation, the scale calibration shall be performed using calibration gas.

(c) If the sample handling system is not integral with the analyzer, make certain that the effectiveness of the gas sampling system are leakproof. Check that filters are clean, that filter holders are fitted with their gaskets and that these are all in good condition.

(d) Ensure that the sample handling line and probe are free from contaminants.

From what I understood, the tester should accelerate the engine speed up to 2,500rpm BEFORE the test not during the test.

ANNEX "C"
FREE ACCELERATION TEST FOR IN-USE COMPRESSION-IGNITION MOTOR VEHICLES

1. Scope

The test is a smoke opacity measurement for in-use motor vehicles equipped with compression-ignition (diesel) engines, using the free acceleration from low idle speed method.

2. Motor Vehicle Test Condition

a. The test shall be carried out on a stationary vehicle and the engine shall be first brought to normal operating conditions during a road run or dynamic test. In particular, cooling water and oil should be at normal temperature.

b. The combustion chamber should not have been cooled or fouled due to a prolonged period of idling preceding the test.

c. The exhaust system shall not have any orifice or leaks wherein the gases emitted by the engine might be diluted.

3. Test Equipment

The light-absorption coefficient of the exhaust gases shall be measured with an opacimeter satisfying the conditions laid down in ECE Regulation No. 24, Revision 2E/ECE/TRANS 505. Rev Add 23 Rev 2, Annex 8: Characteristics of Opacimeter.

4. Test Procedures and Smoke Opacity Measurement

a. Follow the opacimeter manufacturer's instruction for on the proper installation, operation/use and checking the accuracy and calibration before and after each test.

b. Set the vehicle gear-change control in the neutral position and the hand-brake effectively engaged.

c. Start the engine and warm it up to its normal operating temperature.

d. Accelerate the engine two to three times (2-3) prior to smoke sampling in order to remove deposits of soot and other carbon particles in the tail pipe.

e. With the engine idling, depress the accelerator quickly, but not violently, to obtain maximum delivery from the injection pump.

Maintain this position until maximum engine speed is reached for about two (2) to four (4) seconds and the governor comes into action. As soon as this speed is reached, release the accelerator until the engine resumes its idling speed. Record the maximum reading of the smokemeter.

f. The operation described in paragraph (4)(e) shall be repeated not less than six (6) times in order to clear the exhaust system and to allow for any necessary adjustment of the apparatus. The maximum opacity values read in each successive acceleration shall be noted until stabilized values are obtained. The values read shall be regarded as stabilized when four (4) consecutive readings are within a hand width of 0.25 m-1 and do not form a decreasing sequence. The arithmetic mean of the four stabilized values shall be the test result for the concerned vehicle.

In diesel engines you need 4 consecutive readings and the mean of that reading will be the test result. Parang hindi ata yun yung ginawa?

Yes, you will have to fully depress the accelerator quickly but not violently during the test. What does violently means? Hehehe Baka yun yung ginawa sa TS?

Sorry double post... nagloloko net ko..

[coiter]

Maintain this position until maximum engine speed is reached for about two (2) to four (4) seconds and the governor comes into action.

di ko rin masyadong gets to. does this mean na dapat halos i-redline nila?

[benchman]

tama kayo sir kurby..dapat sila ang isaksak sa tambutso..haha!

Dito sa Laspiñas LTO nirerev ang engine kahit motor or sasakyan mapa diesel or gasoline rev lang ng rev. nung pag pa test ng lolo ko doon binatukan yung nag tetest. sabi sisirain mo sasakyan namin paabutin ba naman ng 8000rpm. nabatukan tuloy. tapos lipat kami sa LTO Parañaque

yan ang dapat sa mga taong maiitim pa ang kaluluwa kesa sa usok ng tambutso ng mga bus sa edsa na dinededma nila

[Wh1stl3r]

Mali pala basa ko, Annex C ang pang diesel engines. Eto ang mahirap. "Maximum engine speed" is open to abuse since never naman natin nireredline ang diesels natin sa regular use. Tapos not less than 6! times! Looks like the test is designed to fail. Hindi pa yata nasusunod yung 2-4 seconds.

[badsekktor]

money making scheme ng government.... tsk! kaya ako tinatanong ko buong pangalan nung apprehending officer at saka pinagtatanong ko yun home address.... ang hirap kasi sa kanila, nakatikim lang ng konting authority, nakahawak lang ng baril eh akala mo kung sinong hari na.....

ang tanong eh paano kung resbakan siya sa bahay niya?

peste talaga yang mga yan, ilang beses na rin pinapara yung hi-lander ko sa c5 kalayaan at sa Makati ave. dati, tinatakbuhan ko lang mga kumag. Naglalaway mga yan pag nakakakita ng Isuzu eh, kaya minsan balak ko i-rebadge palitan ko ng OPEL na emblem sa grille para mukhang imported

[istan]

Yes, WOT = redline.
Although, mapapansin mo, di ito ginagawa prior to testing.

d. Accelerate the engine two to three times (2-3) prior to smoke sampling in order to remove deposits of soot and other carbon particles in the tail pipe.

Eto na yun test actually. Autofail di ba.

Violently = bomba. You're running it rich. Sa diesel = usok.
