Exhaust Gas Management

Modern engines make use of their exhaust gas in a variety of ways. Most commonly, the gas is recirculated in order to reduce combustion temperatures and thus reduce emissions.

BorgWarner provides compact and highly efficient solutions reducing fuel consumption and the associated CO2 emissions, including exhaust gas recirculation (EGR) modules, valves and coolers. As a product leader, we are uniquely positioned to produce all EGR components, allowing us to design and develop fully integrated EGR systems.

EGR Systems

Recirculating exhaust gas and combining it with an air and fuel mixture reduces the combustion temperatures that produce harmful nitrogen oxide (NOx) emissions.

BorgWarner develops complete high- or low-pressure EGR systems tailored to its customers’ specifications that reduce fuel consumption and emissions.

EGR Modules

Leveraging its extensive know-how in manufacturing complete exhaust gas recirculation solutions, BorgWarner offers a variety of EGR modules combining valves, coolers, tubes and bypass valves for both high- and low-pressure EGR systems.

EGR Valves

Our electrically actuated EGR valves feature a high actuation force, fast response time, flexible mounting orientations, compact package size and patented anti-contamination / anti-sticking technology. With their high flow capability, excellent sealing and corrosion resistance, they operate reliably in the most severe environments, enabling medium- and heavy-duty commercial diesel engines and vehicles to comply with increasingly rigorous global emissions standards.

EGR Coolers

As a global market leader in EGR cooler technology, BorgWarner has pioneered in the development of exhaust gas heat exchangers to meet increasingly strict emissions standards.
Today, our range of applications, from 0.9 to 92 liter engines, and know-how in this field make us the partner of choice when it comes to developing the next generation of EGR coolers.

Exhaust Gas Recirculation Components

In order to maintain compliance with the increasing stringency of exhaust emissions levels without impairing engine performance, exhaust gas recirculation (EGR) is one of the most frequently used technology for reducing the environmental burden of exhaust pollutants. As such, it ensures the reduction of harmful nitrous oxides and soot particulates. By supplying EGR valves and flaps specifically designed to meet attendant requirements, we are making our contribution to environmentally friendly engine technology.

Electrical EGR Valves

Designed to control the exhaust gas recirculation volume on the basis of a preset electrical setpoint value, electrical EGR valves take their instructions either from a system of control electronics or a simple position sensor.

Electrical EGR Flap Valves

Designed to control the exhaust gas recirculation volume on the basis of a nominal electrical value, these valves can be supplied complete with control electronics or equipped with a position sensor, as required by a specific application.
Electrical Throttle Flap

Electrical Throttle Flap

On diesel engines, and with a preset electrical setpoint value, these devices serve to increase the exhaust gas return volume, the removal of NOx from diesel particulates, and to dampen the engine shutoff "slap".
