LPG emissions of harmful gases and other internal combustion engine emissions of the same gas as the following components:
Unlike diesel engines, there is no particulate matter discharged from the LPG engine.
The generation and discharge of carbon monoxide (CO) is due to insufficient combustion of fuel. CO is a colorless, odorless, toxic gas. LPG contains a considerable amount of CO When the engine is working in a closed environment, such as: warehouse, construction of the building or tunnel, carbon monoxide will increase rapidly. Its concentration has threatened people's health, people feel dizziness, suffocation or death. In general, the use of LPG engine indium, CO has become a central concern.
Hydrocarbons (HC) are also due to the insufficient combustion of fuel. By the fuel component
LPG emissions contain a certain amount of hydrocarbons. Although not as gasoline engine emissions of HC has toxic ingredients, the harm to the environment is relatively small. But the hydrocarbons still produce a certain taste so that the indoor operation of the LPG staff nausea.
The nitrogen oxides (NOx) are produced by the action of oxygen and nitrogen under high pressure and high temperature in the engine block. Most of the NOx is composed of NO and NO2, NO2 is a kind of reaction gas, which has great harm to human health. The accumulation of NOx also adversely affects the stored goods, such as the amount of NOx that can turn the white paper yellow. Due to its ozone reduction and smoke, will have a great impact on the environment.
