You’ve seen VTEC on cars, but what does VTEC mean? VTEC has to do with the valves in your engine that help dictate airflow, horsepower and fuel consumption. This Science Garage gets into Cams, lobes, lifters and more before narrowing in on how VTEC works. Cars have single cams, overhead cams, dual overhead cams and even triple overhead cams to help them do their jobs. VTEC is a unique variable cam design that has changed the way we think of engines… get ready, because VTEC just kicked in!
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

💞dis channel and dis dude! VTEC!YEEEAAAA....I was telling my son da difference in my VTEC 150 hp and non-VTEC is I get more POWER!🤣🤣🤣 shut down a ram truck jis dis morning. YeA!he tried to keep me behind 2 slow cars,but I got his 🐎at da lite.yall know da song "the only way to know you love her is to let her go "...he had no choice but to let da Honda go!!!😂😂😂
Could you do some episodes on... Resonators, The inner workings of a catalytic converter, and the ECU.... like what it looks like... what does the processor looks like.. how its made.... how people can mod it... what languages do some of them use.... and more about throttle response... Thanks.
Ok sounds like this is what I have to explain to my colleague who told me that the 2011 Civic 1.8 I just bought will eat no less than 10l in a city. Because, he argued, his friend's mazda is 1.2 and is eating 8-9l at least.
I don't know so much about engines, but I'm sure fuel efficiency is down to more than just stroke volume.
You should talk about the newest i-VTEC. It has cam phasing to make changes to the valve overlap on-the-fly. Increasing the valve overlap at high RPM allows more-complete cylinder filling and exhaust scavenging to occur in the small time that the valves are open. An engine with a lopey idle has a fixed valve overlap that is already wide angle, too wide for low RPM, and both intake and exhaust valves are open simultaneously for too long... decreases low-end power. Cam phasing gives you the best of both worlds.
Almost all cars have variable valve timing now. There are a variety of ways of implementing it but all cars companies have by now figured out how to do it. Back in the day, you could give Honda credit for being one of the first companies to put it in an inexpensive car. But now VTEC is more of a marketing term. It is just like Hemi for Chrysler. Back in the day making hemispheric shaped heads was an impressive innovation. But now a lot of cars have them and Hemi is just a marketing term for Chrysler engines.
