Ignition advance requirements increase with engine load due to the need for optimal combustion timing to maintain performance and efficiency. Under higher load conditions, the engine requires more power, which necessitates an earlier ignition timing to ensure that the fuel-air mixture ignites at the right moment for maximum pressure during the power stroke. Conversely, at lower loads, ignition timing can be retarded to prevent knocking and improve fuel economy. Thus, tuning the ignition advance based on load helps balance performance and efficiency.

What is a vacuum advance mechanism?
A vacuum advance mechanism is a component in a distributor that uses engine vacuum to advance the timing of the ignition system. This helps improve fuel efficiency and engine performance by adjusting ignition timing based on engine load. By advancing or retarding the ignition timing, the vacuum advance mechanism optimizes combustion for varying driving conditions.
How do you set ignition timing on a 1994 jaguar 4.0 engine?
Ignition timing and advances are all computer controlled (ignition amplifier and ECU)based on info from several sensors. No mechanical or vacuum advance at the distributor, and moving it will not change anything.
What is an ignition timing advancer?
Ignition Timing Advancers are mechanical 'bolt-on' pieces to advance the ignition timing of the engine to a specific degree of timing advance. The majority of its application for these parts are for motorcycles or on racing applications.
What is advanced ignition timing?

What Should the total timing advance be on a 1995 Chevrolet 350 engine?
The total timing advance on a 1995 Chevrolet 350 engine should be around 35 degrees. This takes into account the advance provided by the ignition system.

How do I change points to electronic ignition on a 5 hp briggs & stratton small engine?
Where are the timing marks on a 1996 Chevy Corsica 2.2 engine?
There are none. Ignition timing is not adjustable. Ignition timing and spark advance are handled by the engine controller module and the ignition control module, with inputs from various sensors. The engine controller is located by the passenger kick panel. The ignition controller is the thing the ciol pack mount on...it runs about $110 new. The ignition controller is often the cause of rough running, or idle problems as the spark advance function tends to crap out on this model of DIS ignition. Producing a constant error code, and therefore a constant check engine light.
Does hei distributor require vacuum advance?
A High Energy Ignition (HEI) distributor does not strictly require vacuum advance, but incorporating it can enhance engine performance and efficiency. Vacuum advance helps improve fuel economy and throttle response by adjusting ignition timing based on engine load. While many HEI systems can function without it, using vacuum advance is generally recommended for optimal performance in most applications.
Engine operation conditions that most affect ignition timing requirements?
engine speed, engine load, coolant temp, throttle posision and intake manifold pressure

How does the centrifugal advance work?
Centrifugal advance is a mechanism used in ignition systems, particularly in older internal combustion engines, to automatically adjust the ignition timing based on engine speed. As the engine RPM increases, weights attached to a spring-loaded mechanism are thrown outward due to centrifugal force, causing the ignition timing to advance. This adjustment helps optimize engine performance and efficiency, ensuring that the spark plug fires at the right moment for effective combustion. It allows for smoother acceleration and better power delivery across a range of operating conditions.
