A vehicle parts procurement system, barriers to entry Matching relationship between Pyramid OEM and parts enterprises formed by the between vehicle and auto parts enterprises are fixed to each other dependence, the relationship is firm. New entrants to replace the original suppliers more difficult. Two, quality system certification, process audit and product approval barriers Host manufacturers of enterprise supporting parts to choose and control strictly. First of all, parts enterprises must establish an internationally recognized third party quality system, designated host manufacturers such as ISO/TS16949; secondly, to host manufacturers supporting parts factory in all aspects (such as the QCLDM- quality / cost / logistics / development / management five) strict audit and on-site scoring, finally, each manufacturing process audit; a product must go through strict quality audit, and after lasting product installed test. Three, technical barriers Auto parts production enterprises in the production process are mostly formed a unique production process, the production process to improve product performance, product reliability, production efficiency and reduce cost with a unique competitive advantage. In addition, OEM market requires that the supplier has a strong new technology, new product development ability, actively participate in the vehicle manufacturer's product development.

First, foreign parts enterprises to speed up access to Chinese With the Chinese automobile industry to develop in depth, a large number of foreign enterprises to accelerate the pace of investment Chinese parts, such as the world famous parts supplier BOSCH chassis systems second factory in Chengdu. Two, the new energy automotive parts will become a hot spot for investment Chinese have new energy vehicles will be included in the strategic emerging industries, in this situation, the country set up new energy vehicles and key parts of the industrial base of the movement was in full swing, the future of domestic new energy vehicles and key parts of the investment will continue to increase. Three, overseas mergers and acquisitions, mergers and acquisitions will gradually speed up The whole car market price war intensified is also erode the parts industry profit margins, OEMs reduce costs and ensure profits are becoming more demanding. The production scale Chinese auto parts industry is big but did not play a scale effect, so the integration and restructuring of the auto parts industry is imperative. Can foreknow, Chinese auto parts industry will be in the next few years to accelerate the integration stage, on the one hand, domestic enterprises between the horizontal and vertical integration can achieve economies of scale; on the other hand, through overseas mergers and acquisitions to achieve production and market to the optimal allocation

1, to avoid the heat temperature of engine piston is too high, easily lead to overheating and melting holding cylinder; overheating rubber seals, triangle tape, tire, premature aging, decreased performance, shorten the service life; the coil overheating starter, generator, regulator and other electrical equipment, easily burned scrapped. 2, anti avoidance: engine cylinder pad can not be installed in the installation, otherwise it will lead to premature damage of cylinder pad ablation; engine fan blade installation can not get back on; direction of tyre, herringbone tread tires, after the installation of ground mark should be pointing back flip. 3, avoid dirty: fuel filter, oil filter, air filter, hydraulic oil filter screen and various parts such as if too dirty, will lead to the filtering effect of variation. Water radiator, air-cooled engine cylinder and cylinder head heat sink, cooler radiator and other parts are too dirty, resulting in bad heat dissipation and high temperature. 4, to avoid missing: engine valve lock, should be installed in pairs, such as leakage or loss will lead to valve out of control and crashed the piston; engine connecting rod bolts, flywheel bolts, drive shaft bolts installed on the cotter pin, locking screws, insurance piece or a spring pad locking device, once the leak, in the use may lead to serious fault; oil jet engine timing gear chamber used to lubricate the gears once installed will lead to the serious leakage, oil leakage. 5
