Diesel 

Diesel engine is an internal combustion engine that uses light petroleum fuel. This is a gasoline-type piston engine, but only air (not a fuel-air mixture) enters the cylinder during the first stroke of the piston. The piston rises and compresses the air to a very high temperature. At this point, the pump injects fuel, and due to the high air temperature, it catches fire. While the fuel is burning, the piston is lowered (working stroke).

The engine is named after its inventor Rudolf Diesel. The cycle of an internal combustion engine consists of processes: compression, combustion, expansion, exhaust gases. In theoretical cycles, it is assumed that the input of the fuel mixture is instantaneous, which corresponds to the starting point of compression.

Dangerous emissions

The most significant hazardous emissions of this type of engine are:

• Sulfur oxides
• Nitrogen oxides
  
• Hydrocarbons
  
• Soot
  
• Carbon oxides
  

Dictionary

Sulfur oxides - colorless gas with a sharp suffocating odor.

Nitrogen oxides - colorless gas with a sweet odor.

Hydrocarbons - In nature, hydrocarbons are found in liquid, solid and gaseous state. In scattered form they are present in the atmosphere, water, solid rocks (kerogen), in concentrated form - in deposits of coal, oil, gas, gas hydrates.

Soot - powdered residue from incomplete oxidation of carbon-containing substances.

Carbon oxides - colorless, very poisonous odorless gas. It is formed as a result of incomplete combustion of fuel in automobile engines and heating devices running on natural fuels.
