Anti-Lag System By Ignition Delay - No More Turbo Lag

How does an anti-lag system work? What is an anti-lag system? In the video I explain one type of ALS, which uses an ignition timing delay in order to maintain the boost levels provided by the turbocharger for the engine.

Nope, just barely old enough to play rated E video games. Mario kart is my source for all my information.

Depending on the air fuel ratio, you can still have afterfire with a NA engine.

[EngineeringExplained]

Thanks for watching! Don't see any reason why it would.

[EngineeringExplained]

You would need a fairly powerful motor to do so, which would need a separate power supply other than the battery used to start your car/the alternator. Basically, this is why superchargers are run off an engine belt, so that they have enough power to do what they need to. That said, it could be done, it's just a bit cumbersome, complex, and would of course add weight.

[EngineeringExplained]

Rally cars, such as those in WRC would often use systems like these. Turbochargers have advantages over superchargers (no parasitic drag, increases efficiency, see those videos for more detail) that make them worth while, in some applications.

2 step is a rev limiter. One step for launching (holds the revs relatively lower) and the other for when you're driving (rev limit, around redline).

ALS by ignition delay could be done through ECU remapping, yes.

[gautier]

Always a pleasure to find an old video of you Jason :)

[EngineeringExplained]

Could you clarify your question? ALS will mean worse fuel economy, since you're using gas to drive something other than the tires (as well as more of it), and it will likely decrease the life of your car, since certain components are not typically meant to handle these stresses and temperatures.

Dude you are an awesome teacher, there is no way i could have passed any of my exams without these videos. thanks man.

[EngineeringExplained]

^^ Yes. "stoneddoggie" was saying to keep the revs up to maintain boost. This can be done, but once you shift (without matching the speeds) you will have more wear on the clutch.

[skateaz]

These videos are awesome man! I was a little skeptical at first because it's harder for me to understand through hand drawn ways rather than computer illustrations but never the less your drawings aren't bad and your explanations are great! thanks bro :D

[EngineeringExplained]

No, they simply had the exhaust flow into the diffusers. I believe when they let off the gas it caused a noticeable reduction in downforce for the drivers (less grip).

[TRXRVlogger]

Don't lie, nothing abut this is beneficial other then us Men just love the sounds of the Backfiring lol

[EngineeringExplained]

You are correct, there are two ways of doing it. You can cut the fuel, or cut the spark. Either way the engine will stop revving up.

[esnevip]

Relax mate.
You do an amazing job at explaining everything we could need to know in an easy to understand way. Which you clearly put much effort and time into.
So don't worry if it takes some time, as we appreciate the videos and information in the clear and simple way you provide it!

[EngineeringExplained]

This is likely due to a rich air/fuel mixture. When you're heavy on the throttle often times there will be an excess of fuel, and some of it will go unburned once you let off the throttle and there isn't enough air in the cylinders. When this air meets the outside air (oxygen rich) and the hot exhaust tip, it ignites, creating that pop that you often see in racing. I believe the Ascari is naturally aspirated.

[PZZA]

You deserve way more subscribers and views on your video's, you make everything sound so simple and easy! Good job!

[EngineeringExplained]

I suppose, but you need air in there as well, and that would also cause you to have more fuel injectors/fuel lines. Probably more safe and cheaper to just run air lines.

[EngineeringExplained]

Great to hear, glad to have helped you!

[EngineeringExplained]

You were, in fact, the only reason I made this video. :)
