How Engines and Turbos Work
Discover how cars turn droplets of fuel and gulps of air into rotational wheel power. Follow the path of combustion through pistons and crankshafts, then see how turbochargers harvest waste exhaust to create effortless boost.
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 Turning Air and Fuel into Motion and The Turbo Boost Loop. It starts from scratch.

Key ideas in How Engines and Turbos Work
- A cylinder must draw in air and fuel before it can squeeze them
- Spark ignition and the power stroke happen after the mixture is compressed
- Spent exhaust gases are pushed out last before the cycle begins again
- Pistons push straight down along a linear path during combustion
- The crankshaft has offset pins that translate linear downward force into continuous rotational spin
- A bicycle crank uses the exact same geometry to convert leg pumping into wheel rotation
- Power leaves the internal engine assembly via the spinning crankshaft
- The transmission modifies gear ratios before sending rotation downstream
- Axles deliver the rotation across the width of the vehicle to turn the drive wheels
- Only the combustion (power) stroke forces the piston downward with burning gas pressure
- Intake, compression, and exhaust require energy rather than producing it
- The spinning flywheel stores kinetic energy from the power stroke to carry the engine through the other three strokes
- Gasoline requires oxygen to ignite and release energy
- Pumping extra fuel without enough air just drowns the combustion rather than creating more power
- Air volume is the hard ceiling that limits total engine output
- The pedal opens a mechanical or electronic valve to let air in first
