How do you stop exhaust gas?
Reducing Exhaust Fumes
- Change Your Oil and Oil Filter Regularly. Oil helps to lubricate your vehicle, keeping its parts clean, prevent overheating, and minimize excess wear due to friction.
- Change Your Fuel Filter Regularly.
- Change Your Air Filter Regularly.
- Change Your PCV Valve Regularly.
- Drive Smartly!
What is an aftertreatment device?
An aftertreatment system is a method or device for reducing harmful exhaust emissions from internal-combustion engines. In other words, it is a device that cleans exhaust gases to ensure the engines meet emission regulations.
How do you control exhaust emissions?
To control exhaust emissions, which are responsible for two-thirds of the total engine pollutants, two types of systems are used: the air-injection system and the exhaust gas recirculation (EGR) system.
What does a aftertreatment control module do?
The control unit acquires relevant sensor information from the exhaust line and the aftertreatment system (temperatures, pressures, mass flows, urea level, emissions). The sensor values are then utilized to calculate and execute the setpoint values for the SCR- and the Diesel Dosing System (DDS).
What are the four ways to reduce pollutants in the exhaust gas?
Ways to Reduce Air Pollution
- Riding a bike or walking instead of driving.
- Taking a bus or carpooling.
- Buying a car that has greater fuel efficiency.
- Turning off lights and appliances when they are not in use.
- Using energy efficient light bulbs and appliances.
- Buying fewer things that are manufactured using fossil fuels.
Can SCR be cleaned?
The DPF and DOC filters are suitable for pneumatic and thermal cleaning; conversely, because the SCR is a closed unit it is not suitable for the pneumatic cleaning.
How do I fix my emissions problem?
How to Fix Emissions Problems On a Car
- Check the air filter on the air cleaner system.
- Inspect the Positive Crankcase Ventilation (PCV) system.
- Examine the Evaporative Emissions Control (EVAP) system.
- Go over the Exhaust Gas Recirculation (EGR) system.

What causes an engine to derate?
Ambient temperature has a significant effect on an engine’s output. As the ambient temperature increases beyond designed operating conditions, engine derating begins, decreasing its efficiency. AMOT has a range of temperature control products designed to maximize engine output and lower operating costs.
How does an aftertreatment system in an engine work?
An aftertreatment system is a method or device for reducing harmful exhaust emissions from internal-combustion engines. In other words, it is a device that cleans exhaust gases to ensure the engines meet emission regulations. How does an aftertreatment system works?
How does exhaust throttling affect the aftertreatment system?
Intake or exhaust throttling may reduce air–fuel ratio and increase the exhaust temperature for the aftertreatment system (e.g., DPF regeneration, SCR, LNT). Exhaust throttling generally produces less BSFC penalty than the pre-compressor intake throttling.
How does the EGR system reduce NOx emissions?
However, while these are proven paths to reducing NOx emissions, there are trade-offs associated with each approach. EGR limits combustion temperature by introducing cooled exhaust gas into the intake system, reducing NOx.
What are the different types of aftertreatment systems?
Aftertreatment system including the diesel particulate filter (DFP), lean oxides of nitrogen (NOx), trap and selective catalytic regeneration (SCR) have been introduced in the market. C.S. Hardy, D.M. Ainsworth, in Fuel Systems for IC Engines, 2012
