To measure a car's performance, E.P.A. engineers drive it onto a dynamometer, a kind of automotive treadmill.
Of the state's 129 testing lanes, all but 15 have begun using the new method, known as a dynamometer test.
The turbocharged 3TC engine he built for it makes 462 horsepower, as measured on a dynamometer.
In Georgia, state officials did launch an enhanced inspection program in 1997, which, like New Jersey's, featured a dynamometer emissions test that replaced a less stringent idle test.
When the power developed is measured by means of a dynamometer or similar braking device, it is called brake horsepower.
"The car isn't on the track yet, but the engine is running well on a dynamometer and we plan to take it out for track testing in two weeks," he said.
"When Adrian arrived, he said that two things we should do are build a simulator and also introduce a gearbox dyno," Ward continued, referring to a dynamometer that tests the performance of transmissions under volatile, high-speed conditions.
The current inspection systems in those states rely primarily on the treadmill-like device, called a dynamometer, which measures carbon monoxide and nitrous oxide emissions in vehicle exhausts at various levels of acceleration.
The resistance imposed by a dynamometer may be adjusted so that the desired engine speed is established at any throttle position.
Grip force was quantified with a dynamometer.
A dynamometer was designed and produced for measuring the forces.
