    for diesel engines here is the procedure

    PHILIPPINE CLEAN AIR ACT OF 1999
    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.
    g. For motor vehicles designed with several exhaust outlets that are individually connected from paired exhaust ports, the free acceleration test shall be carried out on each outlet. In this case, the values used for calculating the correction to the absorption coefficient shall be arithmetical mean values recorded at each outlet and the test shall be valid only if the extreme values measured do not differ by more than 0.15m-1 For motor vehicles designed with several exhaust outlets connected from one exhaust pipe coming from the engine's exhaust manifold collector, the free acceleration test shall be carried out only on one exhaust outlet, the other outlets effectively blocked to prevent leaks.
    h. Seal the full load screw of the injection pump/delivery system of the motor vehicle after a pass-test to prevent tampering.

    Kanina active na naman ang kotongan sa Magallanes. Galing akong Alabang turning left to Pasay. Wala kang kawala talaga cause nakaharang sila sa sanga ng To Pasay and To Osmena. Akala ko nga paparahin ako. Ready na akong managasa eh.:car::drive1:

    So what is the recommended RPM for the testers to rev your vehicle at? What is maximum engine speed? This is pretty vague and open to different interpretations. Does this mean that they are allowed to rev your vehicle all the way to the red line and maintain that for 2-4 seconds?

    Yeah it does read like they can redline your engine for 2-4 seconds. Crazy.

    The testing procedures are vague indeed...

    I wanna see some bad boy pick on these ASBU guys. Yung tipong isasaksak yung bibig nila sa tambutso ng 4d56 or Crosswind tapos ipapa-rev sa kasama nila at gunpoint. :chopper:

    Sige, hithit! ASBUwaya ka pala ha! O ano, mausok?!

    These a-holes congregate at the corner of Buendia and Osmena highway at around 1130am and up to catch the noontime private folks traversing Buendia. But the mutha-f-cking jeepneys that actually belch smoke like there's no tomorrow are parked right behind their corrupt arses! Stupid!

    Kasing itim ng usok kasi ang mayor ng Makati kaya ganyan kumilos ang ASBU nila.

    Palagi din silang may operations sa Fairview area, near Puregold. Pero mas maayos talaga ang ASBU ng QC kasi mga buses at jeepneys ang nakikita kong pinapara. Isama na din ung mga dilapidated vehicles.

    Basta nagsisiksikan ang mga buses and jeepneys sa innermost lane, alam mo na na meron.

    At least alam mo naman na pag pinara nila un, siguradong bubuga ng usok un kahit hindi mo ibaon ang gas pedal, unlike sa Makati.

    Pagkaka-intindi ko dito sir is hindi naman dapat redline. Apakan lang nila dapat accelerator to a level. Maintain lang sa level na yun hanggang umakyat yun rpm needle and mag-stable. Sa palagay ko di to naiintindihan ng asbu. Redline kung redline ang alam nila
