How Does the Emission Test Held in Ontario?

The emission test is a mandatory practice in Ontario for heavy-duty vehicles. If you are eager to know and processes for the emission test in Ontario, this article can give you a brief insight into it.

Although the emission test is handled differently by different centers across the country and the world at large, we will discuss some common steps followed by the technicians in Ontario. Let’s dive into the discussion!

Test procedures and standards

One of the foremost test procedures for the Vehicle Emission Test in Ontario is the OBD II. The procedure involves diesel-powered vehicles, whether of earlier or newer ranges. The standard weight kept by the emission test centers is 8500 pounds or lesser than that. In the case of failure in the data communication link, a backup test procedure is held to continue the testing.

The gasoline-powered vehicles of not 1995 and older models are tested with Acceleration Simulation Mode (ASM). The primary goal of the test is to simulate the acceleration of the vehicle during the real operation process. The test is held with a dynamometer that looks like a treadmill. The testing for exhaust emission for such vehicles is held with the insertion of probes inside the tailpipes.

The full-time four-wheelers are tested in different phenomena for emission exhaustion. This is because they cannot be deactivated; thus, the dynamometer cannot hold the ASM test with safety. These vehicles are tested with Preconditioned Two Speed Idle Test. In such testing, the measures and samples of the procedure are exhausted while keeping the vehicle neutral. The engine runs up to 2800 rpm in 90 seconds which can vary with different emission testing centers. The Preconditioned Two Speed Idle Test is designated for vehicles ranging from 1995 and older models.

The special consideration for diesel-powered vehicles

The emission testing is differently designed and executed for diesel-powered vehicles. Some of the differences that are common with the majority of the testing centers while diesel-powered testing vehicles are,

• The incapacity of the dynamometer for the majority of diesel-powered vehicles.
• The obtaining of Steady State Opacity Test for 8500 or lesser weighted diesel-powered vehicles.
• The constant measuring of the vehicle’s exhaustion while it is running on the dynamometer.
• A constant simulated speed needs to be maintained on the running of vehicles on the dynamometer.
• The diesel exhaustion is analyzed for its opacity, indicating the particulate presence of the hazardous by-products.
• In the case of the non-fitting of the dynamometer for the emission testing, Modified Snap Acceleration Opacity Test is carried out while keeping the vehicle neutral. It is a modified version of the test used for heavy-duty diesel vehicles in earlier times.

It is always important to get the heed of the emission testing process to understand if the technicians are doing it rightly or not. With the constant efforts and modifications in the testing procedures, the Drive Clean Emission Testing in Ontario is offering the best of the ongoing requirements.
