What is the difference between No. 92 diesel and gasoline?
1 Answers
No. 92 diesel and gasoline differ in the following aspects: 1. Volatility. Gasoline is highly volatile, whereas diesel is difficult to volatilize. As a result, gasoline vehicle pollutants include fuel evaporation emissions, whose components are hydrocarbons (HC). 2. Ease of mixing with air. Gasoline readily mixes with air and tends to stay mixed, allowing gasoline and air to combine uniformly with minimal occurrences of localized over-rich or over-lean mixtures or liquid fuel droplets. In contrast, diesel mixes unevenly with air, inevitably leading to localized oxygen deficiency or excess. When fuel is subjected to high temperatures and oxygen deficiency, it tends to carbonize, forming soot. Diesel combustion also produces some odorous organic gases, which is why diesel engine emissions have a distinct smell.
