Can a gasoline car run on diesel?
2 Answers
Gasoline cars cannot run on diesel. Gasoline vehicles must not use diesel, and diesel vehicles must not use gasoline. To prevent engine damage, the fuel in the tank must be completely drained, cleaned, and then refilled with the appropriate oil for the vehicle. Differences between gasoline and diesel: 1. Different densities: Diesel has a higher carbon content and greater density, while gasoline has a lower carbon content and smaller density. Therefore, diesel is also called heavy oil, and gasoline is called light oil. 2. Different ignition points: Diesel has a higher carbon content, making it easier to ignite, with a lower ignition point of around 220°C; gasoline has a lower carbon content, with an ignition point of around 420°C. This means diesel is more easily combustible, while gasoline is less so. 3. Different volatility: Gasoline is more volatile, and the vaporized gasoline is more likely to ignite upon contact with fire, while diesel is less volatile.
As someone who frequently repairs cars, I've witnessed the tragedy of putting diesel in a gasoline car. The engine is designed for spark ignition, while diesel is thick and difficult to ignite. Once added, it clogs the fuel injectors, causing knocking sounds and black smoke upon startup. In severe cases, it can damage piston rings or the cylinder block. Continuing to drive will inevitably lead to a breakdown. You must stop using the vehicle and have it towed to a shop for fuel draining and cleaning, otherwise the repair costs could amount to thousands. Remember, different fuel systems are incompatible—always check the label before refueling to prevent such incidents.
