Can a Gasoline Car Run on Diesel?
2 Answers
Gasoline cars cannot run on diesel for the following reasons: 1. The fuel injector pressure is insufficient, causing diesel to only partially atomize and enter the cylinder in liquid form, leading to incomplete combustion, carbon buildup, and clogged injectors; 2. Before the spark plug ignites, the high-pressure mixture reaches the auto-ignition temperature, resulting in violent combustion, abnormal pressure in the combustion chamber, and potential engine damage, including cylinder scuffing. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation or cracking processes, primarily composed of aliphatic hydrocarbons, naphthenes, and a certain amount of aromatic hydrocarbons, used as fuel.
Back when I first started driving a gasoline car, I once absentmindedly filled it with diesel during an early morning trip. The engine shook violently as soon as I started it, sputtered for a few seconds, and then completely died—never to start again. Diesel is much more viscous and can't properly atomize and combust in a gasoline engine, often leading to clogged fuel injectors and damaged pistons. I ended up calling a tow truck to haul it to the repair shop, where it cost over 3,000 yuan to clean the entire fuel system. This is no minor issue—if you misfuel, never gamble by starting the engine, or you'll regret the repair costs and compromised safety. Always double-check fuel labels, use the correct nozzle, and avoid driving when fatigued. These small precautions can save you major headaches.
