What is the difference between diesel and gasoline?
1 Answers
Gasoline is highly volatile, while diesel is difficult to volatilize; gasoline easily mixes with air and cannot be separated after mixing, while diesel produces odorous organic gases after combustion. In terms of chemistry: gasoline contains 8-10 carbon atoms, while diesel has 12-15, so diesel contains higher energy. The following are specific differences: Different engines: Relatively speaking, diesel vehicles require a certain temperature to start. If the outdoor temperature is too low, it will have a certain impact on operation. In addition, the engine noise and vibration are relatively large, and the speed is slightly slower. Gasoline vehicles mostly have front-mounted engines, with relatively small operational sensitivity, noise, vibration, and driving speed. Different ignition methods: Gasoline vehicles ignite by mixing with air and pressurizing, then using spark plugs, while diesel vehicles achieve ignition by compressing to increase temperature. Comparatively, gasoline vehicles have an easier ignition method, while diesel vehicles can only start when compressed to a certain temperature. Different volatility: Gasoline molecules are relatively small and easily mix with air for too long, making them prone to self-loss, greatly increasing fuel consumption. Diesel, after compression, makes the mixture with air uneven, thereby greatly reducing the possibility of fuel consumption. Therefore, relatively speaking, diesel vehicles consume much less fuel than gasoline vehicles and are also cheaper.
