Engine development and design (AVL, Australia, FEV, Ricardo, UK)
AVL Austria is a world-famous research and design institution for internal combustion engines. At present, AVL Austria has 45 subsidiaries and branches all over the world, and is the largest private company engaged in the design and development of internal combustion engines, powertrain research and analysis, and the development and manufacture of related test systems and equipment. In China market, Chery, Wei Chai, Xichai and other car companies have close cooperation with Austrian AVL. Among them, Chery's most proud ACTECO series engine was jointly designed and developed with AVL.
Germany FEV Company is a world-famous R&D leader of internal combustion engine, mainly engaged in the research and development of engine technology and the production of engine-related testing equipment. As early as 1980s, German FEV began to sell engine technology to Guangxi Yuchai. At present, its main customers in China are FAW, SAIC, Brilliance and Haima. Among them, the 1.6T direct injection turbocharged engine on Haima 8S, which has just been listed, was jointly built with German FEV company and won the title of "Top Ten Engines in China" in 20 19.
Ricardo Ricardo Co., Ltd. is a world-famous automobile power technology development company with a long history and the oldest engine and gearbox design and manufacturing company in the world. Engineering expertise covers engine assembly control, electronic and software development, as well as the latest power transmission system, especially in automobile and engine research and development technology with rich experience and world-class level.
EFI System (Germany, USA, Japan)
With the development of automobile technology and the strict national emission regulations, all domestic automobiles must be equipped with EFI system. In terms of EFI system technology, Bosch of Germany, Delphi of the United States and Denso of Japan (affiliated to Toyota Group) monopolize almost all EFI market share in China, with Bosch of Germany taking the lead, accounting for more than 60%. For China's automobile market, whether it is domestic or joint venture, whether it is gasoline or diesel, it needs to rely on foreign EFI technology.
Turbocharger (Germany, Japan)
Nowadays, more and more cars are equipped with turbocharged engines, and the core component is the turbocharger. From the global market, the turbocharger market has formed an oligopoly competition pattern. Honeywell, Borgwarner, Mitsubishi Heavy Industries, Ishikawa Island Somo and Bosch Mahler, the five annual turbocharger manufacturers, all come from Germany and Japan, accounting for more than 90% of the global market share, with obvious competitive advantages.
Engine Management System EMS (USA, Germany, France, Japan)
Although the engine is equipped with many advanced technologies, how to make this pile of steel run reasonably and control fuel injection, ignition and emission accurately depends on the engine management system (engine? Management? System) to control. It includes various sensors, ECU, actuators and so on. Even the dual injection, multi-point injection and mixed injection unique to many engines are functions of EMS. This technology also needs to be purchased, and major OEMs do not do EMs. From the perspective of suppliers, companies such as Bosch in Germany, Delphi in the United States, Valeo in France and Denso in Japan have monopolized more than 90% of the global market share.
Engine Piston (Germany, USA, Japan)
Piston is a reciprocating component in the cylinder block of automobile engine. Its basic structure can be divided into top, head and skirt, and the top of piston is the main part of combustion chamber. In work, the main function of the piston is to bear the combustion pressure in the cylinder and transmit this force to the crankshaft through the piston pin and connecting rod. The key components of this engine are also mastered abroad. Among them, German Mahler, American Federal-Mogul, German Kolbenschmidt, Japanese Aisin, Hitachi and other companies occupy the vast majority of the global market share.
Engine Crankshaft (Germany, Japan)
Crankshaft is the most important part of the engine, which bears the force from the connecting rod and converts it into torque, which is output through the crankshaft to drive other accessories on the engine to work. The crankshaft is subjected to the centrifugal force of rotating mass, periodically changing gas inertia force and reciprocating inertia force, which makes the crankshaft bear bending and torsion load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface should be wear-resistant, uniform and well balanced. ThyssenKrupp of Germany, Sumitomo of Japan, Hitachi of Japan and Fuji of Japan are all well-known automobile crankshaft manufacturers, occupying most of the market share.
Spark plugs (Japan, Germany)
Spark plug is an important part of the ignition system of gasoline engine, which can introduce high-voltage electricity into the combustion chamber, make it jump over the electrode gap to generate sparks, and then ignite? Combustible mixture in the cylinder. It mainly consists of a connecting nut, an insulator, a connecting screw, a center electrode, a side electrode and a shell, wherein the side electrode is welded on the shell. In this technology, Japan's special ceramics industry is the market leader, accounting for 30% of the global market share. Secondly, Germany's Bosch and Japan's Denso account for 20% of the global market share respectively.
