Digital Advance Timing Light Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9396
Jlab Export is a leading Digital Advance Timing Light Manufacturer,and suppliers in India
Ignition timing on a petrol engine is checked by freezing the timing marks with a strobe, and this digital light also shows how far the spark is advanced. It reads advance from 0 to 60 degrees BTDC, engine speed from 200 to 10000 rpm, dwell and voltage. It works on 12 V petrol engines with conventional or distributorless (DIS) ignition.

Ignition Timing Practicals
Students clean and chalk the timing marks, clip the inductive pickup on the spark plug lead of cylinder one and connect the power leads to the battery. With the engine idling, they aim the light at the pulley and see where the mark sits against the scale. Using the advance function, they bring the mark to TDC and read the advance in degrees on the display.
Raising the engine speed shows the advance curve. On older distributor engines, pulling off the vacuum hose separates vacuum advance from centrifugal advance. The Coil Ignition System of An Automobile and Electronic Ignition System of An Automobile units show where the spark comes from. Students then move to a running engine such as the EFI Petrol Engine Test Bed.
Frequently Asked Questions
How does the advance function work?
The light delays its flash by the number of degrees set on the keypad. When the timing mark lines up with TDC, the display shows how many degrees before top dead centre the spark fires, from 0 to 60 degrees BTDC.
Does it work on engines without a distributor?
Yes. It works with conventional and distributorless (DIS) ignition systems on 12 V petrol engines. On a DIS engine, clip the pickup on the plug lead of the cylinder that the timing marks refer to.
What else can it measure?
Besides advance, it reads engine speed from 200 to 10000 rpm, dwell from 0 to 99.9% and voltage from 0 to 16 V. Students can check idle speed and charging voltage without a second meter.
Where do I clip the inductive pickup?
Clip it round the spark plug lead of the cylinder the timing marks refer to, usually cylinder one, close to the plug. Keep the pickup and its leads clear of the fan, the belts and the hot exhaust.
Why does ignition advance increase with engine speed?
The air and fuel mixture takes about the same time to burn at any speed. As the engine turns faster, the spark must come earlier in degrees so that peak pressure still arrives just after top dead centre.
