Making new step in perfect exhaust system

Diesel engines, because of their use of lean mixture and because of the high temperatures and pressures involved in their combustion process, produce high levels of nitrogen oxide, and the reduction of these compounds is a unique challenge. nitrogen to suit new standards in many countries. However, the fine particles present in exhaust emissions (sometimes visible in the form of opaque and dark smoke) have always been the subject of greater concern, since they present different health hazards and are rarely produced in large quantities in spark engines. In 2012, it was reported from real-life tests that although the total nitrogen oxide produced by gasoline cars decreased by about 96% through the use of the catalyst, diesel engines still produce nitrogen oxide emissions at a level comparable to those of 15 years ago, which is equivalent to about 20 times higher NOx emissions than cars with gasoline.  The corporation for Kinsbursky Brothers INC brings the perfect exhaust system.

 

The amount and composition of diesel engine exhaust emissions varies according to:

 

the type of engine;

the fuel composition;

maintenance and adjustment of the engine;

the engine temperature;

the workload of the engine.

In addition, three types of visible smoke can emanate from diesel combustion. White smoke (drops of water and unburned fuel) escapes when the engine is started cold, blue smoke (oil and unburned fuel) comes from poorly maintained and poorly tuned engines and black smoke (soot, oil and unburned fuel) indicates mechanical problems. The soot content varies from 60 to 80%, depending on the fuel used and the condition of the engine Footnote 2 .

 

  1. Exposure to exhaust emissions from diesel engines in the workplace

 

Workers are mainly exposed to diesel engine exhaust when breathing gas and soot, which enter their lungs. frequent revelation to diesel engine exhaust can lead to cancer of the lungs or bladder, chronic bronchitis, chronic obstructive pulmonary disease and asthma. According Carex Canada 897,000 Canadian workers are exposed to the exhaust gases of diesel engines in the workplace each year Footnote page 3 .

 

The main sources of worker exposure to diesel engine exhaust emissions are heavy-duty vehicles that use diesel such as trucks, trains / locomotives, buses and forklifts. As a result, employees in the following types of workplaces are the most affected among the sectors under federal jurisdiction:

 

interprovincial trucking and vehicle maintenance and repair locations;

railways, railway repair sites and railway tunnels Footnote 4 ;

bus garages and vehicle maintenance and repair sites;

toll stations, warehouses and garages;

runway vehicles and airport auxiliary equipment, luggage transport service.

 

  1. Federal Legislative Requirements

Part X (Hazardous Substances) of the Canada Occupational Health and Safety Regulations Footnote 5, published as Part II of the Canada Labor Code, requires that where there is a possibility that the health and safety of an employee may be endangered by exposure to hazardous substances (including diesel engines) in the workplace, an investigation is conducted to assess these risks. Proper maintenance of the control measures implemented, as well as employee training, is also necessary.
