How Crumple Zones Reduce Force in Car Crashes Crumple zones reduce force by lengthening the time and distance over which a vehicle comes to a stop, converting kinetic energy into controlled deformation. By spreading the change in momentum over a longer interval (impulse) and increasing the stopping distance (work–energy), they lower peak deceleration and the …
Odometer vs. Odometer: Clearing Up a Likely Mix‑Up There is no difference between an “odometer” and an “odometer”—they are the same instrument that measures the total distance a vehicle has traveled. However, many people accidentally use “odometer” when they mean “speedometer” or “trip odometer.” Below, we explain what an odometer is and clarify the distinctions …
The Five Major Types of Engines Explained The five major engine types are spark-ignition (gasoline) internal combustion engines, compression-ignition (diesel) internal combustion engines, gas turbine engines, external-combustion (steam) engines, and rocket engines. These categories cover the principal ways machines convert fuel or stored energy into motion across road, air, sea, and space. Each type differs …
Gasoline vs. Kerosene: Which Is More Flammable? Gasoline is more flammable than kerosene. At typical room temperatures, gasoline produces ignitable vapors far more readily because it has a very low flash point and high vapor pressure, while kerosene generally needs to be warmed before it emits enough vapor to ignite. This distinction drives how each …
What Does a 2.5 L Engine Mean? A 2.5 L engine refers to the engine’s total displacement—the combined volume swept by all pistons as they move from top to bottom—equal to 2.5 liters, or 2,500 cubic centimeters (about 153 cubic inches).
