Tune up using Timing Light

[finchy18]

aside from regualar change oil, change spark plugs.. etc..
what struck me most is that when the mechanic used a timing light..
uhmm..
Is it really effective?
Does it really tunes your car engine?

thanx

parang...kasi speaking from experience, pag di ako nagpapaganito parang may vibration yung oto ko from the engine bay while running eh. compared to, if ginawa ito, medyo nag hu-humm lang ang tunog ng makita.

pero dunno how the process works though...

[Alpha_One]

It works like this (sort of, please correct me if I'm wrong)

There are marks on your engine that tells you exactly what position the crankshaft is in (timing marks). The timing light is connected to the #1 sparkplug, to make it light up every time cylinder #1 fires. When your engine is turning, and the timing light connected, you light up the timing marks with the timing light. This light will light up at the mark where the timing is set.

Say it's set at 5 degrees advanced (before the piston #1 reaches top position). When your cylinder #1 fires, the timing mark reads on the 5 degrees advanced mark, and the timing light lights up. It does this every other revolution (because there's a spark every other revolution).

Meaning, say 1000RPM ang andar ng engine mo, sisindi ang timing light 500 times per minute at the 5 degree mark. The effect: may nakikita kang "static" image of the timing marks (due to the strobe effect introduced by the timing light) which allows you to get a reading.

fafa vlady, saan ka nagpapa-tune-up?

[OTEP]

Yup. The timing light does not tune the engine. The mechanic will still be the one to make the adjustments. But it is a useful tool for a mechanic who knows how to use it.

Yes, it is effective as it defines exactly when the sparks will ignite, as described by Alpha One.

In my experience, I would place it at 10deg advance,- as the engine feels nimble (also no overheat), and is a 'petrol-saver',- vs. delayed timing.

Thanx Alpha One

gasolinahan bro....

[al00399]

yup sa mga gas stations, meron din sa Servitek

[t2erns]

specially helpful if you're always disturbing the distributor setting.

[legnacilyz]

i know someone here at landargon, araneta, quezon city, malapit sa shell, na magaling mag timing.. without the aid of the timing light.. he is just like, rotating the whole distributor and his only basis is the sound of the engine.. pakiramdaman kung baga.. share ko lang po.. now i know the timing light is used for reading and the mechanic will still be the one who will make futher adjustments! i really have to have my car timed properly.. lakas ng gas consumption! hay... pansin ko lng po, mei mga degrees, like 5, 10, 15 deg. ano ano po ba ang characteristics ng bawat degrees when on them? which is Most efficient, maayos na hatak, ngunit nde ganun ka-takaw sa gas? my engine is 4g32 1.6L

thanks!

cheers!

[legnacilyz]

pahabol ko lang po, ano po ang mga possible problems na mkukuha sa patuloy paring pag paandar ng poorly timed engine?

thanks!!!

[rogie]

same question din po.
ako worry ko kung ang timing belt wala sa timing or wala sa centro ano possible cause. right now im encountering low power on 1st and 2nd gear naiiwan ako sa stoplight. any recommend shop na magaling magtono? sabay ko na din change oil ko. thanks

pa tuned mo nayan timing belt mo bro.

masira engine mo nyan.

ingat

ignition timing too advanced= detonation, power loss,backfire,higher combustion temperature and premature engine wear

ignition timing too much retarded= higher emission, unburned fuel, power loss, wasted energy

[speedyfix]

different cars need different degrees of timing. don't have it adjusted kung walang timing light or kung hindi masabi sayo ng mechanic mo kung ilan yung dapat na nakalagay.
