The main difference between gasoline generators and diesel generators is the following five points.
- Fuel type: Gasoline engines use gasoline as fuel, while diesel engines use diesel as fuel.
- Ignition method: Gasoline engines use spark plugs for ignition, while diesel engines use high-pressure injectors to inject fuel into the pre-ignition chamber, where it spontaneously ignites under high pressure and temperature.
- Engine construction: Gasoline engines are usually smaller and lighter, while diesel engines are usually larger and heavier.
- Exhaust color: Exhaust gas from gasoline engines is usually colorless or white, while exhaust gas from diesel engines is black.
- Sound: Gasoline engines run with a softer sound, while diesel engines run with a duller sound.
