Mini-buses started production in the early 80s of the last century with the combination of technology and trade. However, they have not been favored by the government before they have transferred micro-offers as military-to-civilian projects to military-industrial enterprises. Since the mini-car hire in the late 1980s, the market has been burning for a while. By 1999, five of China's top ten car companies were micro-enterprise companies. They were Tianjin, Chang'an, Wuling, Hafei and Changhe. At the beginning of this century, the state must upgrade taxis and eliminate minibus taxis. Mini-buses began their first “victory and exodusâ€, but this is not easy. Tianjin, which had done nothing in terms of technical quality, was smashed by FAW; Changhe and Suzuki had joint ventures, but Suzuki did not provide technology to Changhe Microbus. After the market shrank, it was annexed by Changan, and later merged with BAIC; Hafei's R & D car was basically unsuccessful. Changan also merged; only Changan and Wuling got out of trouble. In 2009, micro-subsidiaries paid the most subsidies in the country. In addition, the users of agricultural vehicles upgraded to buy micro-offers, and micro-substances sparked another fire. After the financial subsidy was cancelled in 2011, the micro-customers entered the stage of micro-growth, so that they had the second most recent time. Victory Escape."
The second “Victory and Great Escape†is to enter the A0-level MPV market after micro-customers have upgraded and upgraded the micro-customers. This is the beginning of last year and is also the main reason for the rapid development of the MPV market. The first-time entrants have few competitors. , won the opportunity. However, the large-scale micro-offers and A0-class MPVs all have the problems of greatly increased weight, large drag coefficient, and large windward area, and they cannot meet the fourth stage fuel consumption limit standard. The most economical technical measure is to use a small displacement high-speed supercharged diesel engine. By 2006, the country will be able to supply clean diesel fuel of the country's four emission standards. The problem of short lifespan and large pollution of diesel vehicles can be basically solved. Due to the tight schedule, unless the introduction of technology to build a diesel engine plant, most micro-crew and A0-level MPVs will not pass the fourth stage fuel consumption limit standard. Therefore, only a handful of companies can continue to produce such models after 2020, while micro-offers and A0-level MPVs have a market of more than 2 million vehicles per year. Only the strong will be able to get this “cake†in the future. If the car's fuel consumption limit is forced to develop toward miniaturization in the future, the market for small-displacement high-speed supercharged diesel engines will be even greater.
