Noise pollution and health problems. The internal combustion engine is behind virtually every form of high-speed travel that we have today, from early planes to cars to trains. With this advancement in technology have come some drawbacks. 2 of these drawbacks are noise pollution and health problems.
What impact did the internal combustion engine have?
The development of the internal combustion engine helped to free men from the hardest manual labor, made possible the airplane and other forms of transportation, and helped to revolutionize power generation.
What is a negative effect of the development of the internal combustion engine used in most cars?
Since the engines are consuming fuel and air and create heat in the combustion process, nitrogen from the air can be transformed into nitrogen oxides which are reddish brown gases that irritate the lungs and eyes. Pollutants emitted directly from vehicles are not the only cause for concern.
What are the harmful emissions in IC engine?
The main pollutants from four-stroke gasoline engines are hydrocarbons, CO and nitrogen oxides. They are contained in exhaust emissions, but hydrocarbons are contributed both with the exhaust, and with the evaporative emissions.
Why is the internal combustion engine important?
Internal combustion engines (ICEs) and jet engines are important propulsion systems for civil and military applications. These engines are machines that convert heat produced from combustion into mechanical or kinetic energy. Currently, ICEs and jet engines are still driven by and majorly rely on fossil fuels.
How can we prevent air pollution from cars?

What is used in an IC engine to reduce pollution?
The methods and techniques to reduce emission of pollutants from internal combustion engines usually decrease its performance. … This technology is known as Exhaust Gas Recirculation (EGR) and has been applied in both spark ignition engines and compression ignition engines.
What gases are emitted by cars?
Air pollutants such as carbon monoxide, nitrogen oxides, particulate matter, volatile organic compounds and benzene are emitted into the environment by motor vehicles.
