TOP DEAD CENTRE (TDC) AND IGNITION TIMING

When a piston in an engine reaches the top of its travel, that point is known as Top Dead Centre or
TDC. This is important to know because I don't think any engine actually fires the spark plug with the
pistons at TDC. More often than not, they fire slightly before TDC. So how does your ignition system
work, and what is ignition timing all about?
Well generating the spark is the easy part. The electrical system in your car supplies voltage to your
coil and ignition unit. The engine will have a trigger for each cylinder, be it a mechanical trigger
(points), electronic module or crank trigger. Whatever it is, at that point, the engine effectively sends a
signal to the coil to discharge into the high voltage system. That charge travels into the distributor
cap and is routed to the relevant spark plug where it is turned into a spark. The key to this, though, is
the timing of the spark in relation to the position of the piston in the cylinder. Hence ignition timing.
Having the spark ignite the fuel-air mixture too soon is basically the same as detonation and is bad
for all the mechanical components of your engine. Having the spark come along too late will cause it
to try to ignite the fuel-air mixture after the piston has already started to recede down the cylinder,
which is inefficient and loses power.
Timing the spark nowadays is usually done with the engine management system. It measures airflow,
ambient temperature, takes input from knock sensors and literally dozens of sensors all over the
engine. It then has an ignition timing map built into its memory and it cross references the input from
all the sensors to determine the precise time that it should fire the spark plug, based on the ignition
timing map. At 3000rpm, in a 4 cylinder engine, it does this about 100 times a second. In older
systems, the spark timing was done using simple mechanical systems which had nowhere near the
ability to compensate for the all the variables involved in a running combustion engine.
Typically as an engine revs quicker, the ignition timing needs to advance because the spark needs to
get to the cylinder more quickly. Why? Well the fuel-air mix takes a finite amount of time to combust.
It won't burn any quicker or slower for any given engine speed. So for higher speeds, the mixture
needs to be ignited earlier in the cycle to ensure that it begins to burn at the optimum timing point. In
modern systems, this is all taken account of in the ignition timing map. On older mechanical system,
they used mechanical or vacuum advance systems, so that the difference in the amount of vacuum
generated in the intake manifold, determined the advance/retard amount of the timing.

Oil is the blood of your car, and without it, the car isn't going to go far or quietly. Have your mechanic demonstrate how to check your oil properly, and have the oil [[Change the Oli in changed every 3000-3500 miles. While oil manufacturers have claimed that their oil can last 10,000 miles, it is generally best to use the same oil for no more than 5000 miles to maximize engine reliability and efficiency over the long term. Check the oil regularly, about once a week, and change the oil or have it changed when you reach the 4,000–4,500 mile (6,400–7,200 km) limit. .
