“…In addition, China's economy has continued to grow rapidly since the reform and opening up, driving oil demand to rise rapidly (Chen & Zhu, 2019; Wen et al, 2019; Zhang, Shi, & Yu, 2018). To meet domestic oil demand, China's crude oil imports have also risen rapidly, which makes its dependence on oil imports very high (Chen & Zhu, 2019; Gong & Lin, 2018a; Jiao, Zuo, Li, Yuan, & Li, 2017; Xiao, Hu, Ouyang, & Wen, 2019). Due to its massive oil consumption and high external dependence, oil price fluctuations make China's oil industry more vulnerable (Li, Cheng, & Yang, 2017; Jo et al, 2018).…”

Time‐varying effects and structural change of oil price shocks on industrial output: Evidence from China's oil industrial chain

Based on the output data of the oil industry chain from February 2006 to June 2017, we construct a time‐varying parameter structural vector auto‐regression with stochastic volatility (TVP‐SVAR‐SV) model and specifically analyse the time‐varying effects and structural change of oil price shocks on China's output at each stage of the oil industrial chain. The results show that the effects of oil price shocks on output from upstream to downstream in the oil industrial chain are time‐varying, and the dynamic impacts vary under different lag lengths. The increase in oil price driven by oil demand shocks is the major factor affecting output at each stage of the oil industrial chain. In addition, there is a structural change in the impacts of oil price shocks before and after the international financial crisis. With the decline in external demand and the implementation of policies to expand domestic demand, the responses of China's output at each stage of the oil industrial chain to oil price shocks have decreased significantly since the international financial crisis.

“…From the life-cycle perspective, NG electricity-powered EV and NGV pathways can decrease the life-cycle GHG emissions compared to vehicles powered by petroleum-based gasoline by 42% and 10%, respectively. In addition, few previous studies have focused on the quantitative evaluation of petroleum substitution effects of NGV fleets considering multiple types of NGVs in China (Jiao et al 2017;Niu et al 2017). Jiao et al (2017) constructed a conceptual model of substituting automotive fuels and an evaluation model to investigate the substitutive effects of three kinds of substitutive policies in the Chinese transportation industry: NG, ethanol and methanol.…”

Petroleum substitution, greenhouse gas emissions reduction and environmental benefits from the development of natural gas vehicles in China

et al. 2018

This study develops a bottom-up model to quantitatively assess the comprehensive effects of replacing traditional petroleum-powered vehicles with natural gas vehicles (NGVs) in China based on an investigation of the direct energy consumption and critical air pollutant (CAP) emission intensity, life-cycle energy use and greenhouse gas (GHG) emission intensity of NGV fleets. The results indicate that, on average, there are no net energy savings from replacing a traditional fuel vehicle with an NGV. Interestingly, an NGV results in significant reductions in direct CAP and life-cycle GHG emissions compared to those of a traditional fuel vehicle, ranging from 61% to 76% and 12% to 29%, respectively. Due to the increasing use of natural gas as a vehicle fuel in China (i.e. approximately 28.2 billion cubic metres of natural gas in 2015), the total petroleum substituted with natural gas was approximately 23.8 million tonnes (Mt), which generated a GHG emission reduction of 16.9 Mt of CO 2 equivalent and a CAP emission reduction of 1.8 Mt in 2015. Given the significant contribution of NGVs, growing the NGV population in 2020 will further increase the petroleum substitution benefits and CAP and GHG emission reduction benefits by approximately 42.5 Mt of petroleum-based fuel, 3.1 Mt of CAPs and 28.0 Mt of GHGs. By 2030, these benefits will reach 81.5 Mt of traditional petroleum fuel, 5.6 Mt of CAPs and 50.5 Mt of GHGs, respectively.

“…In order to cope with the shortage of oil resources and the increasingly stringent emission regulations, improving thermal efficiency and reducing harmful emissions of gasoline engine have been highlighted by researchers. − Based on the mature in-cylinder direct injection technology and intake turbocharging technology, lean combustion under a high compression ratio can be realized to effectively improve the thermal efficiency of gasoline engine. In order to achieve stable lean combustion, from the perspective of fuel composition of gasoline engine, adding hydrogen-rich syngas to gasoline engine for blending combustion is considered in this paper .…”

It is an effective way to introduce syngas fuel into gasoline engine for blending combustion to improve combustion and reduce emissions. In this paper, the combustion and emission characteristics of the direct injection engine under the condition of mixed combustion of syngas were analyzed by a numerical simulation method. The engine ran at 2000 rpm, and the mass fraction of syngas was from 0 to 20%. The results showed that with the increase in the mass ratio of syngas in the dual fuel, the average pressure and temperature in the cylinder increased first and then decreased. The maximum in-cylinder pressure and in-cylinder temperature increased by 27.5 and 2.97%, respectively. The instantaneous heat release rate also showed a law of first increasing and then decreasing, in which the peak value of the instantaneous heat release rate increased by 32.1% at the highest. In addition, with the increase in the ratio of syngas, the emission of nitrogen oxides in the cylinder gradually decreased, with a maximum reduction of 27.4%. The unburned hydrocarbons first decreased and then increased, with a maximum reduction of 7.6%. Meanwhile, the emission of carbon dioxide was negatively correlated with the ratio of syngas in the dual fuel. With the increase in hydrogen ratio in syngas, the carbon monoxide was gradually reduced, with a maximum reduction of 65%. The carbon dioxide increased first and then decreased, with a maximum addition of 4.8%. The ratio of hydrogen and carbon monoxide in syngas had little effect on the emission of unburned hydrocarbons.
