The Urban Dynamometer Driving Schedule is a mandated dynamometer test on tailpipe emissions of a car that represents city driving conditions. It is defined in 40 CFR 86.I. [2] [3] It is also known as FTP-72 or LA-4, and it is also used in Sweden as the A10 or CVS (Constant Volume Sampler) cycle and in Australia as the ADR 27 (Australian Design ...
ISO 8178 is a collection of steady state test cycles used for defining emission standards for non-road engines in the European Union, United States, Japan and other countries. Test cycle ISO 8178 C1 is also referred to as "Non-Road Steady Cycle" and used extensively. The Non-road Transient Cycle is supplementing it in some modern emission ...
The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.

The regulation took into account various national cycles such as World-wide Heavy-Duty Certification procedure (WHDC) and World-wide Motorcycle Test Cycle (WMTC). [7] It also took into consideration the 1958 Agreement and the 1998 Agreement, those of Japan and the United States Environmental Protection Agency (US EPA) Standard Part 1066.
The World Motorcycle Test Cycle (WMTC) is a system of driving cycles used to measure fuel consumption and emissions in motorcycles. The methods are stipulated as part of the Global Technical Regulation established under the United Nations ’ World Forum for Harmonisation of Vehicle Regulations , also known as WP.29.
Write an automated test that would pass if the variant in the new behavior is met. 3. Run all tests. The new test should fail – for expected reasons This shows that new code is actually needed for the desired feature. It validates that the test harness is working correctly. It rules out the possibility that the new test is flawed and will ...
According to the PMBOK (7th edition) by the Project Management Institute (PMI), cycle time is the "total elapsed time from the start of a particular activity or work item to its completion." [ 3 ] In contrast to lead time , which measures the time that the customer waits for their request to be realized, cycle time only counts the time the team ...
