What are emission control devices in cars?

What are emission control devices in cars?

Emission control devices are installed to meet the exhaust standards of the Clean Air Act for carbon monoxide and hydrocarbons, and it is necessary to know, from a public health point of view, how exhaust emissions may be affected by changes in fuel additives and fuel composition.

What are some devices used to control emissions?

The most commonly used devices for controlling particulate emissions include: • electrostatic precipitators (wet and dry types), • fabric filters (also called bag houses), • wet scrubbers, and • cyclones (or multiclones).

How do you control car emissions?

10 Ways To Reduce Harmful Emissions From Your Vehicle & Go Green!

  1. Get a ‘Pollution Under Control (PUC) Certificate’ for your vehicle.
  2. Go electric!
  3. Switch off the engine when the traffic light is Red.
  4. Drive at a steady speed.
  5. Accelerate gently.
  6. Brake early.
  7. Reduce the overall weight of your car.
  8. Try to avoid rush-hour traffic.

What are considered emissions systems components?

Most Emission Control Systems, Consist Of:

  • Air Pump.
  • Catalytic Converter.
  • Check Engine Light (CIL)
  • Exhaust Gas Recirculation (EGR)
  • Automotive Filters.
  • Gas Cap.
  • Evaporative System.
  • Mass Air Flow Sensor (MAF)

What are the three types of emissions?

The three types of auto emissions are evaporative emissions, refueling losses, and exhaust emissions. It is interesting to note that the car does not always need to be running to be giving off emissions.

What are most vehicle emissions?

Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Over 90 percent of the fuel used for transportation is petroleum based, which includes primarily gasoline and diesel.

What do cars release into the air?

Burning fossil fuels like gasoline and diesel releases carbon dioxide, a greenhouse gas, into the atmosphere.

What is an auxiliary emission control device?

(1) Is an “incomplete truck” as defined in this subpart; or

  • (2) Has a seating capacity of more than 12 persons; or
  • (3) Is designed for more than 9 persons in seating rearward of the driver’s seat; or
  • (4) Is equipped with an open cargo area (for example,a pick-up truck box or bed) of 72.0 inches in interior length or more.
  • What parts control the emission system?


  • Manifold
  • Fuel damper
  • Fuel control block
  • Fuel filter
  • Fuel vapor canister
  • Air pump
  • Vacuum pump
  • Air by-pass valve
  • Warm-up regulator
  • What is the purpose of an emission control system?

    Emission control system. 1. Emission Control System Purpose The emission control systems are installed to reduce the amount of CO, HC and Nox exhausted from the engine. To prevent the atmospheric release of blow by gas HC and evaporated fuel containing HC being released from the tank. 2.

    What is the EVAP emission control system?

    The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.
