What is the ignition point of gasoline and diesel?

[LeHayden]

Gasoline has an ignition point of around 427°C, while diesel's ignition point is approximately 220°C. Gasoline is more flammable, which is why vehicles with gasoline engines start more easily in cold conditions. Differences between gasoline and diesel engines: 1. Ignition method: Gasoline engines require spark plugs for ignition; diesel engines ignite directly by compressing air and fuel in the cylinder. 2. Fuel consumption: Gasoline engines have higher fuel consumption; diesel engines have lower fuel consumption. 3. Noise: Gasoline engines are quieter; diesel engines are noisier. 4. Compression ratio: Gasoline engines have a lower compression ratio, and the air-fuel mixture is ignited, making them easier to start; diesel engines have a higher compression ratio, and the air-fuel mixture is compression-ignited, making them harder to start.
