Can a Diesel Engine with Excessive Under-Exhaust Still Be Used?
1 Answers
The vehicle can still be used, but it will experience insufficient power and contribute to air pollution. Below is relevant information about diesel: 1. Performance: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms approximately 10–22), used as fuel for compression-ignition engines (i.e., diesel engines). It is primarily produced by blending diesel fractions obtained from processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking (further refined and mixed with additives). It can also be derived from crude oil or shale oil through direct distillation or cracking processes. Depending on the properties of the crude oil, diesel can be classified into paraffinic diesel, naphthenic diesel, and naphthenic-aromatic diesel. 2. Applications: Due to the lower fuel consumption of high-speed diesel engines (50–75g/MJ) compared to gasoline engines (75–100g/MJ), the use of diesel engines in large transport vehicles has been increasing. Diesel is widely used in large vehicles, railway locomotives, and ships. It is mainly used as a liquid fuel for diesel engines. Diesel has environmentally friendly characteristics such as low energy consumption and low pollution, which is why some small cars and even high-performance cars have switched to diesel.
