Reduction of Vehicle Emissions Technology

At first glance from the engine emission reduction technologies can be categorized into two major parts, the primary method of emission reduction and secondary emission reduction methods. For the primary method of reducing emissions is as follows:

Based on fuel:

• The use of low fuel nitrogen and sulfur, including the use of non fossil fuel
• Rallying the use of Non-Petroleum Liquid Fuels
• The use of high cetan numbers for diesel and motor octane number for motor gasoline
• The use of gas fuel
• Application of emulsification technologies (fuel mixing with water or other)

Based on the Air Treatment

• The use of exhaust Gas Recirculation Technology (EGR)
• Setup the temperature of the air entering on engine

Based on the Combustion Process

•  Modifications on fuel pump and fuel injection system
•  The timing of fuel injection
• Setup the size of droplets of fuel which is injected
• Direct injection of water into the combustion chamber

Meanwhile, the secondary emission reduction methods are:  

1. Use of Selective Catalytic Reduction (SCR)
2. Application of Sea Water Scrubber technology for applications in ship
3. The use of catalysts magnet mounted on the fuel pipe
4. Use of the catalyst on the exhaust pipes of motor vehicles
