Explain Like I'm 5: Engines: How Combustion Engines Work

By Jeremy Kelly

Vroom Have you ever wondered what makes a car go? Inside every car, truck, mower, and motorcycle is a mighty little machine called a combustion engine - and this book makes it easy for kids (and curious grown-ups) to finally understand how it works.

With short chapters, friendly pictures, and the catchy four-stroke rhythm of "Suck, Squeeze, Bang, Blow," young readers will discover:

- What an engine actually is and what it does
- The science of fire, fuel, air, and spark
- The four-stroke cycle explained step by step
- The main engine parts: pistons, cylinders, crankshafts, valves, and spark plugs
- How fuel and air mix, how cooling and oil keep things smooth, and where exhaust goes
- Different engine types - inline, V, flat, two-stroke, rotary, and diesel
- Engines in cars, trucks, boats, planes, mowers, and generators
- Hybrid and electric cars, and what comes next

Packed with fun facts, a glossary, quick quizzes, hands-on "Try This at Home" activities, drawing pages, and a Certificate of Engine Smarts, this is the perfect first STEM book for kids ages 5-9.
