South Australian Consolidated Regulations South Australian Consolidated RegulationsSchedule 1—DT80 test procedure
(rule 147A)
1 Secure the vehicle on the dynamometer.
2 Set the dynamometer to simulate the correct load
and inertia for the vehicle.
5 Accelerate rapidly to 80 km/hr under
simulated inertia using wide open throttle, making gear changes as required
for smooth acceleration.
6 Decelerate by removing all pressure from the
accelerator pedal, disengaging the gears and gently applying brakes to bring
the vehicle to a standstill.
8 Accelerate rapidly to 80 km/hr under
simulated inertia, using wide open throttle, making gear changes as required
for smooth acceleration.
9 Decelerate by removing all pressure from the
accelerator pedal, disengaging the gears and gently applying brakes to bring
the vehicle to a standstill.
11 Accelerate rapidly to 80 km/hr under
simulated inertia using wide open throttle, making gear changes as required
for smooth acceleration.
12 Maintain speed at 80 km/hr for
60 seconds, then stop sampling. Bring the vehicle to rest.
Note—Explanation of the test procedure—
This test has been designed to evaluate vehicle emissions during typical
'real-world' operating modes and conditions. There are 3 simple modes:
• 3 idle
periods
• acceleration
to 80 km/h 3 times
• maintain speed
at 80 km/h.
The graph below indicates the modes of operation. The actual test will result
in a graph that has more variation than the indicative graph below, because of
the need to change gears when accelerating. Modes B – D and
E – G and H – I have no specific time
interval. All the specified time periods have an error margin of
± 1 second.
The vehicle is accelerated rapidly to 80 km/h 3 times by applying
wide-open throttle.
The driver selects the most appropriate gear change points for the vehicle
being tested to achieve the correct speed.
The vehicle's test mass for road load and inertia settings must be equal to
the mass of the vehicle when operating with ½ its nominal payload,
that is—
• in the case of
a prime mover: (GCM + unladen mass) ÷ 2; and
• in any other
case: (GVM + unladen mass) ÷ 2.
The vehicle's rolling resistance (based on tyre and bearing losses, frontal
area and drag coefficient) must also be calculated and continuously factored
into the dynamometer tractive effort calculations to ensure correct loading.
Empirical algorithms, based on the vehicle's test mass, GVM or other known
parameters, may be used to automatically calculate realistic coefficients for
these variables.
A simplified indicative graph produced by a test follows.
