Red line cycle9/26/2023 There’s a balance that must be met and upsetting that balance may cause your engine to skip a beat and grenade itself in the process. If you go beyond the limits of your components and lean your engine out, there is a chance that you may cause a malfunction due to an improper and dangerously lean or rich air-fuel mixture. Remember, you need a lot of fuel to make a lot of power and your fuel pump needs to keep up, your air intake must have good flow, and your injectors must supply the right amount of fuel to create power. On top of that, high RPMs without good air intake and fueling will cause your engine to either richen too much or lean out. The safeguards are set in place to keep the engine within its specifications and heat efficiencies, which ensures better longevity just in case a driver decides to wring it out all the way. Most passenger cars like the Toyota Vios, Geely Coolray, and even diesel examples like the Kia Sorento come with redlines regardless of their engine type, be it naturally-aspirated gas, turbocharged gas, or diesel. The redline is simply the “safe zone” for your engine to operate in. That isn’t to say that running your engine at high speeds will break it. Given how most modern engines are getting higher and higher in compression ratios, which is a fancy way of saying that the piston squeezes the air-fuel mixture closer to the valves, the risk of a valve coming into contact with a piston grows as the engine speeds up. Most cars come with a specific tune that allows their valves and pistons to work seamlessly together and not come into contact. At high engine speeds, the valves and pistons are moving at an extremely fast rate to produce power as demanded by the driver. Chief of these two parts that get awfully close together during a typical combustion cycle is the valves and the pistons. TIn a traditional motor, you have multiple parts that are working in tandem to create kinetic energy.
