How can the smoke's intensity be measured?
The measurement involves a light source emitting light of intensity E0 and a light detector that measures the intensity of the light beam (E) once it passes through the smoke.
What is K value in diesel engine?
An average electronic controlled DI Diesel engine (non-common rail) with catalyst would produce around K=0.5m-1 to K=1.5m-1 . ... During research values of between K=0.3m-1 and K=1.4m-1, were measured on similar CR engines of different makes.
What are the effects of smoke from vehicles?
Motor vehicle emissions contribute to ambient levels of air toxics known or suspected as human or animal carcinogens. Exposures to air toxics can also cause noncancerous health effects, such as neurological, cardiovascular, respiratory, reproductive and/or immune system damage.
What is released by motor vehicles in their smoke?
Carbon monoxide- This odorless, colorless gas is formed by the combustion of fossil fuels such as gasoline. ... Hazardous air pollutants- These chemical compounds, which are emitted by cars, trucks, refineries, gas pumps, and related sources.
What is smoke density?
Effective particle density of cigarette smoke was independent of particle size. ... The average effective particle density was determined to be 1180±113 kg/m3.
What is smoke meter?
Smoke meters, also referred to as opacity meters, detect and measure the amount of light blocked in smoke emitted by diesel engines from cars, trucks, ships, buses, motorcycles, locomotives and large stacks from industrial operations. ... US EPA has established Heavy Duty Diesel Test Standards.
What is a smoke opacity test?
A Smoke Opacity Test for a diesel truck engine is equivalent to a traditional smog test for a gasoline engine vehicle. Smoke opacity meters are instruments measuring the optical properties of diesel exhaust. These instruments have been designed to quantify the visible black smoke emission.
How does a diesel smoke meter work?
The smoke meter detects and measures the amount of light blocked in a sample of smoke emitted from diesel engines in cars, vans, buses, coaches and trucks. The smoke meter readout displays the smoke density, giving out a measure of the efficiency of combustion.
What is opacity limit?
With regards to stack emissions, opacity is the degree to which visibility of a background (i.e., blue sky) is reduced by particulates (smoke). The EPA Method 9 Opacity Observation Form, provided in Appendix A, is the enforceable monitoring record which evaluates the quantitative 20% opacity limit.
What is car smoke called?
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle.
Which of the vehicle do not give off smoke?
Bicycle and green vehicles are the vehicles that do not produces smoke...
How does automobile exhaust contribute to air pollution?
The exhaust is the major source of air pollution. This is composed of completely oxidized constituents such as H2O and CO2, both of which are considered harmless. Emphasis is placed on the partially oxidized components -- nitrogen oxide, carbon monoxide, and hydrocarbons -- as being the major pollutants.
Which type of pollution is created by vehicles smoke?
vehicles produce smoke which has unburned carbon particles in it which pollute the air. Explanation: therefore the pollution created by vehicles is air pollution...
What should we do 1 vehicle is emitting more smoke?
Vehicles are emitting more smoke thus the air is continuously polluted. Thus to keep the environment clean we should reduce the use of vehicles and we should ride bicycles for short distances.
Is smoke less dense than air?
Gravity causes hot air to rise because it's less dense than cold air, and gravity causes smoke to fall because it's more dense than air.
What is ASTM E662?
ASTM E662 is a test method that measures the optical density of smoke. With this type of smoke density test, a sample of no more than three inches by three inches by one inch is exposed to an electrical radiant heat source that's rated at 2.5 watts per centimeter squared.
