Analysis of Marine Diesel Engine Emission Characteristics of Different Power Ranges in China
Year: 2021 Language: English Author: Zhongmin Ma *, Yuanyuan Yang, Peiting Sun, Hui Xing, Shulin Duan, Hongfei Qu and Yongjiu Zou Genre: Research Paper Publisher: MDPI Edition: 1st ed. Format: PDF Quality: eBook Page count : 13 Description: In order to accurately assess China’s port air pollution caused by the shipping industry, two main methods can be used to calculate the emissions of ships, including the method based on ship fuel consumption and the method based on ship activities. Both methods require accurate diesel engine emission factors or specific emissions. In this paper, the emission characteristics of NOX, CO, CO2, and THC from 197 domestic marine diesel engines were tested under bench test conditions by a standard emission measurement system. The diesel engines were divided into six Classes, A~F, according to their power distribution, and the fuel-based emission factors and energy-based emission factors of marine main engine and auxiliary engine meeting IMO NOX Tier II standards were given. The results showed that the main engine fuel-based emission factors of NOX, CO, CO2 and THC from Class A to Class F were 33.25~76.58, 2.70~4.33, 3123.92~3166.47 and 1.10~2.64 kg/t-fuel, respectively; and the energy-based emission factors were 6.57~11.75, 0.56~0.81, 530.28~659.71 and 0.18~0.61 g/kW h, respectively. The auxiliary engine fuel-based emission factors of NOX, CO, CO2, and THC from Class A to Class D were 27.17~39.81, 2.66~5.12, 113.01~3141.34, and 1.16~2.87 kg/fuel respectively; and their energy-based emission factors were 6.06~8.33, 0.47~0.77, 656.86~684.91, and 0.21~0.61 g/kW h, respectively. The emission factors for different types of diesel engines were closely related to the diesel engine load, and the relation between them could be expressed by quadratic polynomial or power function. The results of this paper provide valuable data for the estimation of waterway transportation exhaust emissions and a comprehensive understanding of the emission characteristics of marine diesel engines.
