Great video on explaining how compression ratio works! One thing though, boosted engines (turbocharged/supercharged) generally require a lower compression ratio than naturally aspirated engines because of the increased pressure and so, higher volume of air/fuel inside the cilinder. The higher the boost pressure, the lower you want your compression to be. (Fuel octane rating is also an important factor for what comoression ratio youre gonna use)
@@homeopathicfossil-fuels4789 True, for normal road going vehicles 95octane is generally used the most. High performance cars/bikes often use higher octane rated fuel like 98octane and racecars usually use special fuel that has 102octane. (Keep in mind that Europe and USA use different octane ratings.)
@@homeopathicfossil-fuels4789 there are 2 kinds of octane ratings used. RON (Research octane number) and MON (Motor octane number). RON is a measure of a fuels resistance to knocking or pre-ignition under low engine speed and load and MON is the measure for high engine speed and load. Europe uses only RON as their octane rating and the USA uses the average of RON and MON as their rating also known as AKI (anti-knock index)
I am a 28 year old girl/woman who burned out on programming, I am now interning at a car mechanic, this is a godsend, thank you. You have earned a subscriber!
Thanks for sharing this video, Gabby. Not many pretty girls like you dive into engines. There's a lot of misconception about high octane fuel being superior. Take my younger brother, for instance; he always splurges on high octane fuel for his tiny Honda Jazz, and he's not alone. You should explain why it's unnecessary for so many people to make that mistake. Love ur videos ❤❤❤
Yeah a lot of people think it is better and makes your car faster, when really if doesnt do anything. Might male throttle response ever do slightly quicker due to it burning slower, but performance wise, unless you have a performance car, its the same as putting a massive expensive wing on a 1L mini 😂 thank you for the positive feedback :)
Hello, very good video, hope you learn something making them as well as teaching the others. 12.5 : 1 compression ratio is not for turbo or supercharged engines, nor is exclusively for bigger engines. So high compression ratio is only for high revving naturally aspirated motorsport engines. I'm sure you can find some information about it and extended your knowledge. Good video, remember that!
Thank you for your feedback. I realised I got it mixed around, me while filming was talking nonsense for that part haha. We’re all learning as we go :)
This is a platform where anyone can learn anything. I hope i can help out some people who are just getting into cars and want to know more. Trying to keep the passion for cars alive :)
@@thatcarchick I know you did a good job. Now it's my turn. By starting fights in the comments section, TH-cam picks up on video comment activity and bumps your YT vids higher.
@@TheBusinessMindset_ I do know what compression ratio is, on a theoretical level since I sleuth off to random engineering info sources when I do work that bores me at an easy enabler of that particular sort of sleuthing, like a desktop computer. But not how it works in an ICE and the general automotive specific facts and knowledge?

arent octane ratings pretty invariant for regular civilian road vehicles? Like 95ish

Yes that is correct. My apologies i got it mixed around
@@Dawneryse I guess different machines for testing it or something?

That sounds great! Glad we can get another car person on board. I wish you the best success in your new journey. I hope these videos help you
Can you please explain horse power vs torque?
That’s a great idea. I’ll work on it!
@@thatcarchick excellent 👌🏻
This explained it perfectly. Thank you 😁
the glazing is crazy
very well explained!
I tried my best. Thank you 😁
so well explained I actually got it 😀
Glad I could be of assistance :)

🤪 Imagine not knowing what compression ratio is
Imagine being that guy...
