Engines spin at thousands of revolutions per minute (RPM), which is too fast and weak to move a heavy car from a dead stop. Newton explains how the transmission solves this problem:
Students preparing to enter vocational school for automotive repair find this to be the perfect foundational primer.
How Cars Work by Tom Newton is a highly-regarded, 96-page introductory guide designed to simplify the complex mechanical and electrical systems of automobiles. Originally developed by Newton, a school psychologist, to improve reading comprehension for teenage students, it has evolved into a standard primer for adult beginners, DIY enthusiasts, and even automotive professionals to help explain repairs to customers.

How Cars Work by Tom Newton is far from a traditional textbook. Published in 1999 by Black Apple Press, this 96-page paperback is a completely illustrated primer that serves as a high-interest, accessible entry point into the world of automotive technology. The book's enduring popularity is evident in its widespread use across various settings, from high school classrooms to adult literacy programs and even by automotive service managers who use it to explain repairs to their customers. how cars work by tom newton pdf
Readers consistently praise the book for achieving precisely that goal:
Newton starts with the engine, describing it as an “air pump” that converts fuel into motion. The core process is the four-stroke cycle (intake, compression, power, exhaust). He explains that pistons move up and down inside cylinders, turning the linear motion into rotational force (torque) via the crankshaft. Critical components like spark plugs, valves, and the timing belt are introduced with clear analogies—for example, comparing valves to a door that opens and closes at precise moments.

Tom Newton breaks down a vehicle into its most fundamental systems. By isolating these systems, readers can understand how individual components interact to move a two-ton machine down the road. 1. The Internal Combustion Engine (ICE)
Read the relevant page before attempting a DIY repair, like changing your brake pads or replacing an alternator.
Unfortunately, I don't have direct access to the paper or its PDF version. However, I can suggest some possible ways to obtain it: Originally developed by Newton, a school psychologist, to
Why the cycle matters: repeated combustion pulses create rotating power that, after smoothing and gearing, drives the wheels.
Modern cars rely heavily on electronics. Newton introduces the battery (storage), alternator (generator), starter motor (engine cranker), and fuses (protection). He also explains the engine control unit (ECU)—a small computer that adjusts fuel, spark, and emissions based on sensor data (oxygen sensor, throttle position sensor, etc.). This demystifies why a “check engine” light can indicate anything from a loose gas cap to a failed sensor.
