Engines And Parts In China R & D Capability
Engine Machine and Parts R & D has always been our weakness
, although we have the basic technology and development capabilities, but the lack of competitiveness of core technology for energy saving Environmental protection The control is not strong, a large extent are dependent on foreign imports. The following engine and parts of China research through product development capabilities to analyze four dimensions, including product development methods, resource control key components, key technologies, product development based on the basis of ability.
1. Basic local machine with the engine variant product development, technology upgrading capacity, but the new platform development and whole concept of oil supply system Electronic Control system development is still a large number from abroad or rely heavily on foreign companies.
We will develop the engine into the local machine technology upgrades, variable products, the new generation product development platform for the four levels. Survey showed that when the company needs new engine platform, one-third choose products directly from abroad, 25% of companies have chosen to "joint development with foreign countries" is to describe a new platform for enterprise development engine, is still largely dependent on foreign products of foreign companies.
We will develop the engine into the engine machine concept development, 5C engine parts (cylinder block, cylinder head, crankshaft, camshaft, connecting rod) structure, development, matching engine, and the combustion system, fuel system, cooling system , into the exhaust system, post-processing system electronic control system development. Survey results show that the engine concept development machine parts structure development on the engine 5C, respectively 46.2% 45.5% enterprises directly from abroad usually means; 60% of enterprise fuel supply system, electronic control systems development, the use of foreign development mode from the foreign direct import. Therefore, the concept engine machine, 5C piece structure and fuel injection system the engine electronic control system-critical systems development, the Chinese enterprises dependent on foreign high technology companies.
2. 5C pieces of engine control ability, but on a large number of purchased parts relating to energy saving system control capability, and Diesel engine Weaker than gasoline.
Survey, the survey cylinder block and head to the main home-made, crankshaft, camshaft purchase outside the main bar. Gasoline engine fuel injection system, electronic control systems, exhaust gas after-treatment system, variable valve timing system, turbocharging systems, the key components related to energy saving systems, are "fully outsourcing" component systems, the business of these systems ability parameters defined integration capabilities are weak.
3. The key technological base is generally weak, with the electronic control system based on the most relevant technology development capacity is weak.
Basis of our key technologies into the engine capacity of CAE analysis, kinematics / dynamics analysis capabilities, thermal analysis capabilities, electronic control systems development, product technology heavy-duty engine, light engine technology, product technology 6. Survey, the survey of the six technologies to master all the technical details of the ratio is generally low, except kinematics / dynamics analysis capabilities than an average of 60%, and the remaining five technologies mean an average of 30% and below water.
4. Product development based on capacity to meet the "basic a" level, trial ability, but a big gap between testing capacity.
On Transmission Assembly manufacturers involved in product development based on capacity analysis of the key components of product development resources and control of three ways.
1). Country Car Transmission production is still mainly mechanical transmission, automatic transmission mainly relied on imports. Currently, the global high-end passenger cars with automatic transmission as high as 90%, compared to just 30% of the country, and the automatic transmission 78% dependent on imports.
2). Mechanical transmission capacity of a strong product development, assembly and parts development can be completed by domestic independent. Transmission components include: dry clutch, gearbox housing, gears, synchronizer, differential, parking brake, shift fork, Bearing , Hydraulic oil supply system (pump / filter), cooling and lubrication system, pneumatic systems. Survey data indicate that mechanical transmission products in China with strong independent development capacity.
