Car Mechanics and Everyday Upgrades
Understand how cars work from the engine bay to the wheels, and learn the essential logic behind modifying them for speed, sound, and handling.
Like Duolingo, but for Car Mechanics and Everyday Upgrades. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through How Cars Make Power and Speed and Grip, Stance, and Balanced Upgrades. It starts from scratch.

Key ideas in Car Mechanics and Everyday Upgrades
- Piston pulls fresh air and fuel into the cylinder during intake
- The mixture gets squeezed tight before a spark ignites it to push the piston down
- Spent exhaust gas is pushed out through the exhaust manifold
- The air intake loop starts at an open box with a pleated filter and leads directly to the engine
- Thick hoses run from the engine block to the radiator up front to shed heat
- The battery and alternator keep ignition, sensors, and accessories powered
- Engine oil points are marked on top of the engine for checking and refilling lubrication
- Torque is low-end twisting force that gives strong off-the-line launch feel
- Horsepower measures how quickly that work gets done at higher engine speeds
- A car can have high peak horsepower but feel sluggish from a dead stop if low-end torque is weak
- Forced induction rams extra air into the cylinder under pressure
- More air packed in allows the engine to burn more fuel per stroke, creating a bigger combustion kick
- A small 4-cylinder engine with a turbo can produce the power of a much larger naturally aspirated engine
- Fresh oil is amber and smooth, while dirty, broken-down oil turns black, gritty, and loses lubricating film
- Degraded coolant discolors to rusty brown and can no longer protect against overheating or corrosion
- Fresh brake fluid is light and clear; it absorbs moisture and darkens over time, lowering its boiling point
