Fuzhou Ruida Machinery Co., Ltd,
is a wholly-owned subsidiaries of Hong Kong GuGu Industrial Co., Ltd who had been specialized in diesel fuel injector's design and production for about 15 years.After the 15-years development, we own 7 manufacture plants located separately in Shandong Province, Zhejiang Province, Fujian Province and Henan Province. We have alreaday been in top rank diesel fuel engine parts manufactures in China mainland and started to provide high quality OEM products to serve all worldwide customers.Our product range from diesel fuel injector to injector nozzle and then other diesel engine spare parts.Our products cover more than 2000 different types of diesel injectors and injector nozzles compatible to Bosch, Caterpillar, Cummins, Delphi, Siemens VDO and Denso.All of them are produced by latest machines imported from Germany and are 100% tested by experienced technicians before delivery.Our corporate mission: To provide high quality engine parts products to our customers and fulfill their needs at the reasonable price.We are sincerely willing to cooperate and establish long term business relationship with more and more customers from all over the world.The 3rd generation of
Common Rail
makes diesel engines even cleaner, more economic, more powerful and quieter.The key is the innovative injection system: it works with rapid switch, compact piezo-inline
injectors .Some advanced
common rail fuel systems
perform as many as five
injections
per stroke.The
injector
of the
Common Rail System
contains the
injection nozzle , an actuator in the case of piezo
injectors
or a
solenoid valve
in the case of solenoid injectors plus the hydraulic and electrical connections to trigger the nozzle module. An
injector
connected to the rail via a short high-pressure line is installed in each engine cylinder.The electrical, hydraulic servo system in the
injector
receives control impulses from the EDC (Electronic Diesel Control) to open and close the nozzle module. It is triggered either by a
solenoid-valve
or a piezo actuator.Injectors
with a piezo actuator can have a slimmer design and achieve reduced switching noise. Both technologies achieve similarly short switching times and permit pilot, main and secondary
injections . In this way, fuel combustion can be designed to be efficient and clean at all operating points.
