Why Fuel Injectors are AWESOME (28,000 fps Slow Mo) Part 1 - Smarter Every Day 281

Summary by Krater

The creator visits Cross Creek Tractor to film fuel injectors spraying fuel at high speed in slow motion using a Phantom camera, comparing a bad injector pattern with an even, atomized one.

From the video

Answers: How do tractor fuel injectors work in slow motion?

• fuel injectors
• tractor parts
• high speed photography
• combustion process
• carburetor vs fuel injector

What it concludes

• An ideal fuel injector spray pattern is even across all holes and evenly distributed inside the cylinder.
• Uneven fuel injector spray patterns lead to incomplete combustion, black exhaust smoke, poor fuel economy, and eventually engine failure.
• Diesel engines rely on compression and hot gases to ignite the atomized fuel, unlike petrol engines which use a spark plug.
