How Engines and Turbos Work
Understand the mechanical magic under the hood. Follow the path of fuel and air as it transforms into wheel-turning power, and see how turbos capture waste exhaust to deliver massive performance.
Like Duolingo, but for How Engines and Turbos Work. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through The Engine's Mechanical Heartbeat and Forcing Air with Turbochargers. It starts from scratch.

Key ideas in How Engines and Turbos Work
- Trapped combustion creates rapidly expanding, superheated gas
- Because the cylinder is sealed, expanding gas has nowhere to go except pushing the movable piston
- The piston's downward push is the primary physical source of engine power
- Pistons move exclusively in a straight line up and down
- The crankshaft has offset pivot points that convert straight thrust into rotation
- Wheels require rotary spin, which straight piston pushes cannot provide directly
- A single cylinder's power stroke is a brief, isolated shove
- Offsetting the combustion events delivers smooth, uninterrupted spinning momentum to the crankshaft
- Firing all cylinders at once would produce violent, jarring pulses separated by dead zones
- The crankshaft spins first as pistons push it
- The transmission receives this spin and manages gear speed and power delivery
- The piston moves downward like pulling a syringe plunger, creating low pressure inside the cylinder
- Outside atmospheric air rushes into the lower-pressure space, carrying atomized fuel with it
- The intake valve opens to create a pathway for this incoming mixture
- Squeezing air and fuel into a small pocket concentrates the energy in a confined space
- A compressed mixture burns faster and generates dramatically higher peak pressure than an uncompressed flame
