Powertrain

FUELING THE FUTURE

Tenneco's Powertrain team designs, develops, and manufactures original equipment components and technologies that help engine designers tackle the toughest challenges, from strict regulations to demanding market requirements, all around the globe.

Gas, diesel, alternative fuels, and hybrids - we've got it covered. Our advanced systems and specialized coatings are key to cutting emissions, boosting fuel economy, and pushing engine design forward. We're talking everything from small 25 mm bore engines to engines with over 1,000 mm bore and more than 100,000 hp.

We're not just players in the OE light vehicle, commercial truck, and off-highway markets - we're leaders. And we don't stop there. Our tech is fueling the power generation, marine, rail, and industrial sectors, too.

Pistons

Pistons help engine designers increase temperatures, combustion pressures and loads - critical developments for more efficient combustion. Our range of proprietary pistons manufactured using state-of-the-art processes are tailored for specific market sectors, contributing to lighter, more compact engines with higher performance, greater efficiency and durability. 

Piston Rings

Tenneco's industry leading piston ring designs rings resist high temperature and very abrasive environments without significant wear. With combustion pressures and temperatures increasing and oil control now recognized as a critical aspect of reducing particulate emissions, piston rings are a vital area for innovation. Advanced materials, coatings and design features developed by Tenneco engineers help manufacturers to meet engine challenges head-on. 

Cylinder Liners

Achieving outstanding component interactions depends on dimensional consistency, and that relies on expertise in design, analysis, materials and manufacturing: all areas where Tenneco has considerable strength. Nowhere is this more important than for cylinder liners that must provide a high-quality running surface for the ring pack as well as excellent heat transfer.

Bearings

Whether for automotive, off-highway or industrial applications, our bearing technologies deliver environmentally friendly solutions that combine high performance, reliability and exceptional lifetime. Tenneco offers the full breadth of material and manufacturing technologies necessary to provide lead-free solutions for the entire global engine and transmission market.

Sealing, Gaskets and Heat Shields

New challenges for joint sealing and heat shielding are constantly emerging as temperatures, pressures and mechanical loads increase and target assembly times are reduced. Meanwhile, packaging space and joint face geometry is more restricted as engine compartments become increasingly crowded.

Tenneco Powertrain meets these challenges by developing superior sealing and shielding solutions for vehicle, transportation, rail, machinery and industrial markets worldwide. 

Valves

Tenneco develops and manufactures high quality engine valves and valvetrain components that address high temperatures and mechanical loads. Our advanced materials and manufacturing expertise ensure outstanding thermal characteristics and durability. Our portfolio comprises monometallic, bimetallic and hollow valves, so valve design and material can be selected specifically to give the optimum combination for each individual customer application. 

Valve Seats and Guides

Advanced valve seat and valve guide technologies from Tenneco use high performance powder metal materials that withstand the extreme tribological requirements of the combustion environment and deliver industry leading thermal conductance to cope with rising temperatures in even the most demanding engines. This enables vehicle manufacturers to achieve CO2 reduction strategies using turbocharged, direct injection and ethanol-capable downsized, high output engines, without having to compromise their designs. 

Large Bore Engines

High Efficiency Components for Large Bore Engines

Tenneco is at the forefront of Large Bore Engine (LBE) technology, serving diverse industrial markets from maritime and rail to power generation. Our expertise spans both 2-stroke and 4-stroke engines with bore sizes above 145 mm. In an era of unprecedented change and new technical challenges, we're helping manufacturers meet demanding requirements for reduced emissions, improved efficiency, and lower operating costs. Our award-winning portfolio includes high-performance pistons, piston rings, bearings, valvetrain components, and ignition products. By leveraging our extensive engine experience and cutting-edge research capabilities, we provide innovative solutions that extend engine life cycles and improve performance.
