Spark Advance Control Spark Advance Control - Love Horsepower!
Effects of Spark Advance on Emissions and Driveability • Too much spark advance, particularly during high engine load conditions, increases the likelihood of engine detonation and increases combustion temperature and pressure. This results in an increase in HC and NOx output, decreased engine performance, and ... Read Here

Model A Ford Technical Report
The correct timing and spark advance is critical to the efficient performance of the engine. Ford recognized early on that this timing function was too important to be manually controlled. They came up with a “better idea” and developed a mechanical spark advance mechanism that was matched to the RPM of the engine. ... Document Viewer

MSD Enhancer Ignition For The Honda TRX400EX
Approximately 30,000 volts to the spark plug. Spark Plugs: With the MSD Enhancer, it is recommended to use as cold a spark plug as possible while still being able to start the engine easily. The spark plug gap will largely depend on the compression of the engine. The higher the compression the smaller the plug gap you must run. ... Doc Viewer

Spark Advance Modeling And Control - Fs.isy.liu.se
The spark advance determines the e ciency of spark-ignited (SI) engines by po-sitioning the combustion in relation to the piston motion. Today’s spark-advance controllers are open-loop systems that measure parameters that e ect the spark-advance setting and compensate for their e ects. Several parameters influence the ...

The Model T Ford Ignition System Spark Timing
Linear spark timing can be obtained by moving the spark lever. This would appear best for optimum engine performance, but Model T coils do not work well on the 6 volt battery at higher engine speeds. As you can see in Figure 8, when running on the magneto, timing advance is not linear. The spark lever is a ... Fetch Here

3. Check the advance. The simple way to evaluate the advance is simply grab the rotor and turn it. This will activate the mechanical advance and give some indication if there is a problem in the distributor. If you can turn it one way against the springs and it snaps back to the original position when it is released, it is fine. 1. ... Access Full Source

The operator could vary the spark advance with the lever for best performance (such as it was), or just leave it alone (which most operators chose to do). With that big, low-compression, slow-running, low-powered engine, little damage could be done by improperly setting the spark advance. Fast-forward to the 1960s and ... Read Full Source
