CD1000 MOTORCYLE CHASSIS DYNAMOMETER

motorcycle dynamometer- Combined inertia & dynamometer testing

- 225 kW (300 BHP) power absorption

- 300 KPH (180 MPH) speed capability

- Optional starter system

- No more "street" testing

- User friendly Windows based software

- Designed for proposed emission tests

- UK designed & manufactured

- Lease purchase available

Depending on budgets and the type of testing to be undertaken, PIPER offers two models:

CD 1000I - Inertia test system
This type of test is ideal where a quick power verification and acceleration test is required. It does not allow for any steady speed or constant load problem to be simulated. All CD1000I models are manufactured to accept the retro-fitting of the CD1000IA dynamometer unit.

CD1000ID - Inertia and dynamometer test system
This dynamometer test allows for constant load testing, necessary if fuel injection or ignition mapping are undertaken or if part throttle misfires are to be detected. The addition of a gas analyser during dynamometer testing enables air/fuel ratios to be optimised.

Advantages associated with PIPER Chassis Dynamometers

Can it create a power curve?
CD1000I - Yes
CD1000ID - Yes

Can it simulate an inertia load?
CD1000I - Yes
CD1000ID - Yes

Can it simulate a misfire under acceleration?
CD1000I - Yes
CD1000ID - Yes

Can it hold constant speed without load?
CD1000I - Yes
CD1000ID - Yes

Can it vary an acceleration rate?
CD1000I - No
CD1000ID - Yes

Can it simulate a misfire at a constant load?
CD1000I - No
CD1000ID - Yes

Can it hold constant torque?
CD1000I - No
CD1000ID - Yes

Can it plot air/fuel ratio & BSFC values?
CD1000I - * No
CD1000ID - Yes

* To monitor air/fuel ratios, brake specific fuel consumption (BSFC) and exhaust emission values, additional monitoring equipment will be required.

Software and Instrumentation

- User friendly Windows based software

- Software written 'in house'

- EEC approved components used in all electronics

The monitoring hard and software used with the PIPER Chassis Dynamometers is a development of the successful PIPER EDA engine monitoring system. To achieve industry leading accuracy and repeatability, the roller speed/acceleration is monitored using high-resolution sensors and dedicated computer counters. PIPER Windows based software ensures friendly, easy to learn operation.
The CD1000I is supplied with a hand-held controller fitted with push buttons to activate the computation of the engine RPM-roller speed ratio and further buttons to stop and start the performance test, the CD1000IA has additional controls for the display, monitoring and storage of data.
