Measurement principle Sample Clauses
Measurement principle. The emissions to be measured from the exhaust of the engine include the gaseous components (carbon monoxide, total hydrocarbons for diesel engines on the ESC test only; non-methane hydrocarbons for diesel and gas engines on the ETC test only; methane for gas engines on the ETC test only and oxides of nitrogen), the particulates (diesel engines only) and smoke (diesel engines on the ELR test only). Additionally, carbon dioxide is often used as a tracer gas for determining the dilution ratio of partial and full flow dilution systems. Good engineering practice recommends the general measurement of carbon dioxide as an excellent tool for the detection of measurement problems during the test run.
Measurement principle. 2.1 The opacity of the exhaust gases produced by the engine shall be measured with the engine running under full-load and at steady speed.
2.2 A sufficient number of measurements will be carried out ranging between the maximum rated speed and the minimum rated speed. The extreme points of measurement shall be situated at the limits of the interval defined above and one point of measurement will coincide with the speed at which the engine develops its maximum power and the speed at which it develops maximum torque.
Measurement principle. The emissions to be measured from the exhaust of the engine include the gaseous components (carbon monoxide, total hydrocarbons for diesel and type 3B dual-fuel engines on the ESC test only; non-methane hydrocarbons for diesel, dual-fuel and gas engines on the ETC test only; methane for gas and dual-fuel engines on the ETC test only and oxides of nitrogen), the particulates (diesel and dual-fuel engines only) and smoke (diesel and dual- fuel engines on the ELR test only). Additionally, carbon dioxide is often used as a tracer gas for determining the dilution ratio of partial and full flow dilution systems. Good engineering practice recommends the general measurement of carbon dioxide as an excellent tool for the detection of measurement problems during the test run."
