The article considers variables registered in the WLTP procedure. The test results of a passenger car with a compression-ignition engine have been analysed. The tests were carried out on a chassis dynamometer. The tests were performed for engine cold start and ran up to the point of reaching stabilized operating conditions. The average specific distance emissions and volumetric fuel consumption were assessed for individual test phases as well as for the entire test. It was found that the results in the first test phase, which corresponded to the engine cold start up to stabilized operating conditions, had the most significant impact on the overall exhaust emission and fuel consumption results in the test. The specific distance emissions of carbon monoxide, non-methane hydrocarbons and nitrogen oxides were by far the highest in the first phase of the test. In the fourth phase of the test, the specific distance emissions of methane and carbon dioxide turned out to be the highest, as well as the operational volumetric fuel consumption being the highest.

“…Wang et al (2020b) found that fuel consumption between WLTC and RDE was at the same level, while the fuel consumption of CLTC-P was 8.41% higher than that of WLTC. Some studies (Geng et al 2021;Ma et al 2021;Yang et al 2021) also have investigated the emission characteristics of different emission control technology routes under the CLTC-P. However, there is still a lack of a large number of test research on CLTC-P, and a uni ed method for quantitatively evaluating CO 2 emissions measured under different test cycles is yet to be established.…”

The influence of CO2 on Earth’s climate warming is significant. To quantitatively evaluate CO2 emissions in different test cycles, eight China 6 light-duty vehicles were tested under WLTC, CLTC-P and one RDE test, respectively. This study indicated that the CO2 emissions in all three test cycles were influenced by factors such as test weight, vehicle shape, and transmission. Additionally, the RDE test was also affected by road traffic conditions and driving style. There was a strong linear correlation (R2 = 0.99) between the CO2 emissions of CLTC-P and WLTC. The coefficients for Low Speed and High Speed were greater than 1, while the coefficient for Medium Speed was less than 1. Vehicle speed was the primary factor influencing CO2 emissions at Low Speed, whereas acceleration was the main factor at Medium Speed. Furthermore, there was also a strong linear correlation (R2 = 0.99) between the CO2 emissions of RDE and WLTC/CLTC-P, with coefficients close to or exceeding 1. Comparatively, utilizing data from both WLTC and CLTC-P provided more consistent errors compared to using only the measured CO2 emissions from either test. Overall, the estimated CO2 emissions using all three methods remained within an acceptable range under the four conditions.
