Wow i never knew my girlfriend and car engines had so much in common

[squishycrab]

Weird to see l how much piston shape has evolved over time.

[CaptainSNES]

Damn talk about a non interference engine

[mechanicallycreative]

Usually engines dont fire right at tdc. Takes a moment for flame to propegate. When tuning a car ignition timing is where you find alot of power. You add advance but not so much that your igniting too early causing detonation. Thats how you break pistons. On the opposite end if you did ignite at tdc you would actually be pushing on the piston after it was on the way down losing power.

Holy mother of valve seat recession, those exhaust valves don't look right.

[norsevikingsir]

Putting dished pistons in these increases the power and speed significantly without a need for further modification

[taylorstout]

Nice to see you are trying to get rid of the heat issue

[Jon-kz]

Looks like the exhaust cam lobe is wore down the valve hardly ooened.

It's not an explosion per say it's the expanding hot gas during combustion that rapidly builds pressure within the cylinder and since the piston is the only thing that can move the hot combustion gas is allowed to expand and fill in the void is pushes down on the piston. The flame front is moving at a subsonic speed during normal combustion If it's an explosion the flame front is moving at a supersonic speed which is bad it's called detonation or pinging which can be caused by using the wrong octane fuel for example in a high compression engine or of the engine is running too lean. Detonation can lead to serious internal engine damage such as cracking a piston or even blowing a hole right through it.

Good explination of the SSBB and shows it well

[budgetbuild]

Ayo you gotta say !!NO DIDDY!! After that my boy

[valeriyreiter]

Such a little valve opening)) Now I see why it has such a low horsepower from stock engine. I know gas was bad in these days, many people used kerosene or anything that burns. But these valves - oh maaan)))

Martincitopants, my summer car part 1. If you know, you know.

[JamesAnderson-fwew]

It must burn so much oil with how little cross hatching the cylinder walls have

[BedsitBob]

The cylinder doesn't move down. The piston does.

[gambleoakranch]

I live down south of Castle Rock Co. Can I come up and drive it. I have always wanted to drive a model T. I will let you come down to my property (70 acars)and you can off road it, I have a creek you can cross with it. We can blow some stuff up with tannerite aswell

[Genstone]

I wonder if the shape of that piston made a channel for compression loss to happen

[calhountubbs]

Thought he was talking about an ig or of chick at first.

[shellstud]

Yeah Tommy maybe intake stroke compression stroke, power stroke, exhaust stroke, little to xxx

[Momo_Kawashima]

So that's why cars are like women
