Engine dynamometer method Clause Samples
The "Engine dynamometer method" clause defines the procedure for testing engine performance using a dynamometer, a device that measures force, torque, or power. This method typically involves mounting the engine on a test bench, connecting it to the dynamometer, and running it under controlled conditions to record data such as horsepower, torque, and fuel efficiency. By standardizing how engine output is measured, this clause ensures consistency and comparability of results, which is essential for verifying compliance with performance standards or regulatory requirements.
Engine dynamometer method. The maximum power at the crankshaft is measured on an engine dynamometer according to Regulation No. 85 for each parent vehicle(s) with the following fuels:
(i) commercial petrol or diesel fuel,
(ii) commercial LPG, The mean of power measurements shall be calculated as follows: n Powerpetrol = 1/n ∑ Powerpetrol.i n PowerLPG = 1/n ∑ PowerLPG.i The ratio of engine power shall be calculated as follows: Kpower = PowerLPG / Powerpetrol For each vehicle of the family, the official values of engine power are multiplied by the above ratio.
