Experience

Renowned as a great place to work, Cummins Turbo Technologies works hard to attract and retain the best talent. Specialists and experts across all the key fields of engineering contribute to our capacity and capability to optimise technologies with high investment in training and professional development in our worldwide technical centres. Fresh talent is combined with experience in diverse teams that work in partnership with customers to provide the expertise and innovation required to drive success.

Understanding Engines

We have developed detailed knowledge of engines through long standing OEM relationships spanning over 50 years and as an autonomous unit of the Cummins organisation. This enables us to develop new turbomachinery using engine performance simulation software and engine test cells to optimise the application of turbochargers for customers. Our understanding ofengines is essential to ensure complex air handling solutions work, including turbocompounding, engine braking and aftertreatment thermal management.

Understanding Applications

Many of our customers have applications with high power ratings with little margin for error. When engines and turbochargers are pushed this hard, it is important to know where boundaries and limits lie for each application. Cummins Turbo Technologies has decades of experience in specifying turbochargers for a wide range of arduous highly cyclic, high altitude and high temperature applications as well as more conventional on highway trucks and light duty applications.

Aerodynamic Design

In house turbocharger and wheel geometry design capabilities using inverse design techniques optimise performance and position the maximum efficiency just where you need it. Our patented map width enhancement gives Holset turbochargers the widest compressor map width of any turbocharger available on the market and our patented variable geometry turbines are the most popular Brand in heavy duty markets worldwide.

Mechanical Design

Our Applied Mechanics team ensure that the turbocharger designs are physically robust enough for their applications. Pressure, thermal and centrifugal loads combine with vibration and external loads to provide a complex stress situation that must be thoroughly understood to ensure turbocharger durability without adding excess weight or cost. The noise and vibration characteristics of the turbocharger are also engineered to meet customer requirements.

Materials

Holset turbochargers have had titanium compressor wheels as an option since 1999 and many aerospace materials and coatings have been used in our VGT turbochargers since their introduction in 1998. Research into new materials and coatings continues to reduce any wear, corrosion and fouling and our research into new technologies such as waste heat recovery systems has brought new materials into use.

Electronics

Our range of electric actuators has been developed in house by specialist mechatronics engineers with on-board electronics to communicate with the engine. Many functions relating to turbocharger operation are taken care of by the turbocharger itself, including speed and position sensing, feedback control and self diagnostics.
