About Sieruyi Ltd

Sieruyi ltd was established in October 2019, which is located in Guangzhou, Guangdong Province, China. In the past 5 years, Sieruyi ltd has been committed to the development of test equipment and related spare parts

for electronic control actuators of engine intake and exhaust systems. The company ‘ s current products are mainly divided into following types:

1. Automotive testing and calibration equipment:

Thanks to the research and development of turbocharger electronic actuator testing and calibration equipment represented by iturbo3, Sieruyi has laid a solid professional foundation in the ϐield of automotive electronic control. Based on the research and development of iturbo3 control equipment,in the past 4 years, we have developed professional capabilities in communication control research and development in all ϐields of automotive electronics, We have

independent research and development capabilities for the widely used J1939 CAN bus, SENT, LIN, PWM, and Analog communication protocols. The improvement of basic research and development of communication control protocols has provided us with a rich accumulation of know-how. In addition to testing equipment in the ϐield of turbochargers, we are also continuing to develop and design:

(1. 1) Test equipment of the post-treatment system: Test products cover urea pump, nitrogen and oxygen sensor, ETV exhaust throttle valve, EGR valve

(1.2) Intake system test equipment: electronic throttle, intake air ϐlow sensor

2. VGT turbocharger electronic actuator

Cummins Holset series aftermarket VGT electronic actuators are currently one of our company ‘ s main products. Our VGT electronic actuator products cover: HE3, HE4, and HE5 series. The main challenge for the Cummins HOLSET VGT turbocharger electronic actuator in the after-sales market is that the VGT needs to be compatible with the relevant test equipment of the original vehicle manufacturer in order to complete the relevant installation and calibration. Otherwise, the VGT will not be compatible with the ECU. Currently, our VGT electronic actuators are fully and seamlessly compatible with the following brands of original software and equipment.

1)Cummins:Insite/Calterm

(2)Volvo/MACK:TechToo

(3)Paccar/DAF:DAVIE

(4)Detroit:DDDL

(5)Scania:SDP3/VC

(6)GMC/FORD:MDI2

The 100% compatibility support of the above equipment will preserve the habit of using commonly used software for our customers, provide customers with convenience and reliability in repair and diagnosis, and also provide solid technology for our products to be reliably used In the market.
