On July 3rd, Schaeffler held a ceremony at the Taicang manufacturing base to celebrate the formal commissioning of the new generation of electric cam phase adjustment system (ECP).
Through more rapid and accurate valve timing adjustment, the new generation system can improve vehicle driving comfort and further improve engine fuel economy, power performance and emissions.
The product has won a number of local customer projects and will first be applied to the plug-in hybrid of a well-known domestic automaker.
In hybrid models, the internal combustion engine is still the key component that affects the efficiency and performance of the whole vehicle.
Schaeffler has a wealth of system knowledge and leading technology in the field of engine variable valve timing technology, which can play an important role in supporting customers to develop more efficient engines and meet the requirements of hybrid applications.
” Schaeffler Group engine and gearbox system division valve mechanism business unit head David Kehr said.
The new generation of electric cam phase adjustment system is faster and more accurate.
in the application of hybrid power, the engine is changing to the role of hybrid special engine (DHE).
The change of working conditions puts forward different technical requirements for the development of engine.
For example, on hybrid cars, the engine starts and stops more frequently, which leads to NVH problems such as noise and vibration.
The electric cam phase modulation system can realize the timing adjustment of the valve before or during the start-up of the engine, reduce the pressure in the cylinder during start and stop, and make the start and stop of the engine more smooth, so as to improve the driving comfort.
In addition, the large advance of cam timing can also make the engine increase the torque faster during acceleration and improve the engine transient response speed, which not only helps to improve engine efficiency, but also enables the vehicle to obtain better driving performance.
In 2015, Schaeffler began to produce electric cam phase adjustment system.
Compared with hydraulic drive system, Schaeffler electric cam phase adjustment system has been applied in more and more customer models because of its remarkable advantages.
On this basis, Schaeffler continues to carry out technical research and development and product upgrading.
The new generation of electric cam phase adjustment system put into production has higher integration, faster adjustment speed, more precision and wider adjustment range.
The new generation system is composed of intelligent motor and reducer, in which the motor adopts brushless DC motor with long life and maintenance-free.
The system adopts the latest topology and integrates the power module and control software into the motor for the first time.
The use of Schaeffler’s mature control software can reduce customers’ software integration and calibration work.
The system also supports client software control, which is conducive to the application of the product platform.
The reducer adopts the harmonic reducer which is widely used in the industrial field, and Schaeffler is also the first supplier to use the harmonic reducer in the electric cam phase adjustment system.
The latest generation harmonic reducer not only has the advantages of compact structure, light weight and low noise, but also has the advantages of high reliability and precision.
In addition, the whole system adopts modular design, which can adapt to all kinds of hybrid special engine applications according to the different needs of customers.
Schaeffler is always committed to the development of electrification with innovative technology, and Schaeffler is always committed to the development of powertrain electrification, providing comprehensive solutions from spare parts to the whole system according to customer needs.
to meet the needs of different forms of electrification applications.
For the special hybrid engine used in hybrid cars, Schaeffler offers innovative products, in addition to the electric cam phase adjustment system, but also includes balancing shaft system with rolling bearing and special raceway, shock absorber, engine components such as oil-free hydraulic tappet, lightweight roller rocker arm, etc.
, to meet the higher space, efficiency and NVH requirements of the special hybrid engine.
Wu Hao, senior vice president of engine and gearbox systems in Schaeffler China, said: “Hybrid technology plays an important role in the development of electrification, and hybrid models have a huge market demand in China.
The mass production of the new generation of electric cam phase adjustment system shows that we give full play to our technical advantages in the field of internal combustion engines, constantly carry out product innovation, and better support the development of customers’ new models by strengthening the construction of local production capacity.
to help promote the development of the new energy vehicle industry.
