Types of Model Cars The main types of model cars are static scale display models (including diecast and plastic/resin kits), radio-controlled (RC) cars, slot cars, and 3D-printed or scratch-built customs. These broad categories differ by how they’re used (display vs. driving), how they’re constructed (prebuilt vs. kit vs. custom), the materials involved, and the scales …
Why Cars Usually Catch on Fire Cars most often catch fire when heat from engines or electrics meets flammable materials—typically leaked fuel or oil, overheated exhaust components, or faulty wiring. Collisions that rupture tanks or batteries, neglected maintenance, and, more rarely, battery thermal runaway in electric vehicles are the leading pathways that turn small faults …
Can ChatGPT diagnose car issues? It can help narrow down likely causes and suggest next steps, but it cannot deliver a definitive diagnosis on its own. ChatGPT can interpret the symptoms you describe, explain OBD-II trouble codes, and outline basic checks; however, it can’t inspect parts, read live sensor data directly from your vehicle, or …
What Is a Power Door Lock? A power door lock is an electronically controlled mechanism that locks and unlocks a door—most often in cars—via a switch, remote key fob, or smartphone.

The total cost of ownership depends on mileage, insurance …
What Happens When You Put Your Car on Cruise Control When you engage cruise control, your car’s computer takes over throttle (and, in many modern vehicles, braking and regenerative deceleration) to keep a set speed—or a set following distance with adaptive systems—while you remain responsible for steering and supervision. In practice, that means the car …
What Does a Backing Plate Do? A backing plate is a rigid base that supports, aligns, and distributes loads for attached components; in practice, it provides structural support, keeps parts correctly positioned, reduces vibration, and can shield against heat or debris. Depending on the field—automotive brakes, power tools, welding, or structural fastening—the backing plate’s function …
How to Clean Gunk Inside an Engine The most effective way to clean gunk inside an engine is to identify the type of deposit—oil sludge/varnish, intake-valve carbon, or fuel-system/combustion carbon—then use targeted methods: frequent short-interval oil changes with high-detergent oil (and only cautious use of flushes) for sludge, walnut blasting for gasoline direct-injection intake valves, …
How Tire Pressure Sensors Work: The Technology Keeping Tires Safe and Efficient Tire pressure sensors monitor the air pressure (and often temperature) inside each tire and send that data to a vehicle’s control unit via radio signals; if a tire is underinflated, the system triggers a dashboard warning.
