TECH NOTES
RIPP Technical information about cylinder flame speed and how an upgraded ignition system will directly effect power.
An Internal combustion engine's "flame speed" refers to the rate at which the air-fuel mixture burns during the combustion process. This speed significantly impacts engine performance and efficiency. The faster flame speed will increase cylinder pressure. When a spark is hotter, it ignites the air-fuel mixture more rapidly, leading to faster combustion, and an increase in pressure. Higher cylinder pressure = more torque pushing down on the piston.
Flame front propagation speed: As the flame front propagates faster across the combustion chamber, the fuel burns more efficiently, releasing more energy. This, in turn, enhances the engine's power and responsiveness. Additionally, with a faster flame speed, the combustion process is completed sooner, reducing the chance of incomplete burn or unburned hydrocarbons being released into the exhaust gases. In summary, optimizing the flame speed by utilizing more spark energy can significantly improve engine performance. It enables the engine to operate more efficiently, delivering increased power output, improved fuel economy.
Spark Energy is measured in Millijoules (mj). A Factory coilpack will generate 35.8mj. This mj value is considered low for the cylinder displacement value, piston surface area and air/fuel mixture. A RIPP coilpack will generate 53.6mj. This 17.8mj increase over stock will dramatically increase pressure per square inch across the piston surface. At first start up you'll immediately notice a smoother operating engine, and a "calmer" exhaust tone. This is due to less waste or unburnt hydrocarbons and fuel. Engine response and engine horse power will increase throughout the RPM range.
