Chassis dynamometer test for heavy vehicles

The Environmental Protection Department (EPD) will extend an advanced smoke test, which uses a chassis dynamometer, to smoky diesel vehicles over 5.5 tonnes under its Smoky Vehicle Control Programme starting December 28, 2000.

The chassis dynamometer test is more revealing than the current free-acceleration smoke test as it can test smoke emissions of a vehicle under real-life operating conditions.

To introduce the test, the EPD will help the transport trade and the vehicle maintenance trade understand the advanced smoke test by organising demonstration sessions, free trials, as well as technical seminars on vehicle maintenance between December 28, 2000 and March 30, 2001.

After the introduction period, smoky vehicles will have to pass the advanced smoke test.

The Assistant Director of Environmental Protection, Mr Tse Chin-wan, said: "To extend the advanced smoke test to heavy duty vehicles is part of the Government's strategy to reduce air pollution.

"A poorly maintained diesel vehicle can emit 10 times more pollutants than a properly maintained one.

"A smoky vehicle must be properly repaired before it can pass the advanced smoke test. The new test will help raise the general vehicle maintenance standard of heavy duty vehicles."

"The advanced smoke test was first introduced to cover vehicles up to 5.5 tonnes in September last year.

"Since then, the number of re-spotted smoky vehicles has dropped by 50 per cent while the number of smoky vehicles has reduced by 15 per cent.

"We anticipate that the extension of the smoke test to heavy vehicles will further reduce the number of smoky vehicles," Mr Tse noted.

He added that the EPD would continue to work with the transport trade and the vehicle maintenance trade in exploring practical measures to improve the emissions from motor vehicles.

Those who want to get details of the demonstration sessions, free trials and technical seminars should call 2755 2501.
