LuftStandardZyklus

LuftStandardZyklus, also known as the Luft Standard Cycle, is a standardized procedure used in the German automotive industry to measure and evaluate the emissions of internal combustion engines. It was developed by the Association of the German Automobile Industry (VDA) and is widely used in Europe and other regions. The cycle consists of two phases: the cold start phase and the hot phase.

The cold start phase simulates the emissions of an engine during the first few minutes of operation, when it is still cold. This phase is particularly important for evaluating the emissions of diesel engines, which can produce high levels of particulate matter during this period. The hot phase simulates the emissions of an engine after it has reached its operating temperature. This phase is used to evaluate the emissions of both diesel and gasoline engines.

The LuftStandardZyklus is designed to be a realistic representation of real-world driving conditions. It takes into account factors such as engine speed, load, and temperature, and is used to compare the emissions of different engines and vehicles. The results of the LuftStandardZyklus are used by regulatory bodies to set emissions standards and by manufacturers to develop and improve their engines.

The LuftStandardZyklus is regularly updated to reflect changes in technology and emissions standards. The most recent version of the cycle, known as the Luft 13, was introduced in 2013 and is used to evaluate the emissions of vehicles sold in Europe from 2017 onwards. The cycle is also used in other regions, such as China and India, where it is known as the China 6 and India 6, respectively.
