Holset® e power: no best, only better

Are you also in the commercial vehicle market?

Are you also looking for a more perfect turbocharger?

Recently, Wuxi Cummins Turbo Technology Co., Ltd. has released a supercharged turbocharger: the Holset ® e. It captures the advantages of current pneumatic bypass valve booster technology and variable nozzle booster technology in terms of performance and reliability, and provides engine manufacturers with cost-effective booster solutions.


Holset ® e power provides engine manufacturers with cost-effective booster solutions

The performance of HOLSET® e is excellent in terms of performance and reliability. How comprehensive is its product performance?

Holset ® e power effectively reduces fuel consumption and emissions;

Realize the closed-loop control of the intake air volume of the engine to better meet the increasingly stringent product consistency requirements;

Compared with the variable nozzle booster, the moving parts under the high temperature and high pressure gas are reduced, and the reliability is higher;

The rapid electronic control response combined with the newly developed high-efficiency compressor and turbine, Holset ® e power reduces the intake lag and improves the engine transient response under conditions of engine changing conditions, and has a vast application space.

In the domestic light commercial vehicle market, e power performance is comprehensive. Specific performance comparison see the following table:

As the world’s first commercial electronically controlled by-pass valve turbocharger technology for commercial vehicles, where is the innovation of the Holset® e power?

1. Active electronically controlled regulating bypass valve

Holset ® e power, compared to the traditional pneumatic bypass valve booster, changes the bypass valve opening mode from passive gas actuation to active electronically controlled regulation control. After receiving the electric signal transmitted by the ECU, the motor inside the electronically controlled regulator rotates, and then drives the linkage mechanism to push the bypass valve to open, and actively controls the turbocharger turbine to perform the function and achieves a certain amount of intake air. Free adjustment within the range to meet the engine's different speed and torque demand for air intake.

2. High torque motor improves reliability

Holset ® e-powered electronically controlled regulators use high-torque motors to effectively avoid the impact of the exhaust valve on the bypass valve system and electronically controlled actuators under harsh operating conditions. The electronically controlled regulator passed 70 million bypass valve opening and closing tests as well as various other harsh tests.

3. Compressors and turbines have a wider flow range and higher efficiency

The newly developed compressors and turbines have a wider range of compressor flow rates and higher turbine efficiencies, which can better meet the user's requirements for large engine torque and high power, reduce the intake lag in variable conditions, and improve transient response. , while reducing fuel consumption.

For more than 60 years, the Holset brand has continued to provide superior turbocharging and aerodynamic technology through its dedication to improving engine efficiency, enhancing reliability, and reducing emissions.
