At the 15th Beijing International Auto Show held from April 23 to May 2, 2012, BorgWarner , the world's leading supplier of power and transmission systems, will demonstrate to the public its focus on improving fuel economy, reducing emissions, and enhancing driving. Dynamic advanced solutions. The theme of BorgWarner's auto show is "Innovation Leads Science and Technology", and it coincides with the theme of this year's auto show, "Innovation Leapfrogging." Not only exhibited its innovative advanced technology turbocharger, dual clutch module, control module, electronic silicone fan clutch, water pump, timing system, torque manager, transfer case, EGR cooler, EGR valve, ignition system; And in the application of new energy electric vehicles for the audience to display the electronic drive bridge, electronic water pump, etc.; In addition, the variable valve timing technology under the BorgWarner timing chain system, the friction plate in the clutch module, and the third generation of EGR valve It also made its debut at the auto show.

Turbocharged system, innovation to fully enhance engine power

As a technology leader in engine turbocharging, BorgWarner is a leading supplier of turbochargers for light passenger cars and heavy-duty commercial vehicles. BorgWarner established a constantly innovating and powerful turbocharger system to help customers calmly meet today's increasingly stringent emissions regulations, provide incentives to enhance driving pleasure, limit fuel consumption, improve fuel economy, and dramatically increase customer competitiveness. .

The current auto show BorgWarner will bring to the audience several masterpieces of passenger car turbochargers:

One-piece exhaust manifold supercharger: Maximize engine room space, higher material grades, complex casting process, applied to popular models Octavia, MAGOTAN, Tiguan 1.8TFSI; gasoline engine variable area turbocharger : The entire range of supercharger operates efficiently, releasing every drop of energy as much as possible. It is applied to Porsche911. It can accelerate up to 60mph in 4s and reach 615Nm in 1950rpm. Two-stage turbocharger: higher boost pressure provides higher power Output, using a BMW 3.0L diesel engine rated at 200 kW, with a maximum torque of 580 Nm at 2,000 rpm. At the same time, in the commercial vehicle field, the large-displacement variable-area turbocharger will also be presented to the audience. Through continuous simulation analysis and optimized design, the efficiency of the supercharger is significantly improved, and the number of assembly components is reduced. The maximum power of MAN10.5L is 305kW.

BorgWarner Variable Section Turbocharger Drive System for Innovative Fuel Economy

BorgWarner is one of the world's leading suppliers of driveline components. Once again, BorgWarner made technical innovations to provide customers with key components and all-wheel drive products with lower fuel consumption and more reliable performance.

The current auto show BorgWarner will present to the audience the dual clutch module and control module applied to VW models, the DL501DCT clutch module and control module applied to the Audi models, all with outstanding control and rapid response for the driver. Accelerated start-ups, smooth gear shifts and optimised fuel economy on cruising.

In the aspect of all-wheel drive products, BorgWarner's TODTM transferor, full name: Torque-On-DemandTM, is another advanced four-wheel drive product for the Chinese SUV market. The ECU of the TOD® transfer case continuously calculates the optimal transmission ratio to be allocated to the front axle and the rear axle according to the driver's operation intention and the road conditions of the SUV, and dynamically adjusts the torque to the optimum transmission ratio. Assigned to the front axle and rear axle; once the ECU detects a poor road surface or slipping of the drive wheels, the TOD® transfer case can automatically switch between two-wheel drive and four-wheel drive without the need for driver intervention.

In addition, BorgWarner also brought eGearDrive?31-01 and eGearDrive?31-03 for electric vehicles to the exhibition. All of them use aluminum die-cast housings to achieve lightweight, compact design, and achieve high torque transmission, high efficiency, and low NVH in a limited space. Take the example of the 31-01 eGearDrive, which was applied to the world's first electric sports car TeslaRoadSter. It can achieve a peak torque of 400Nm, a maximum input speed of 14000rpm, and a transmission efficiency of up to 97%. In 2011, BorgWarner supplied the 31-03 type eGearDrive? for Ford's first mass production pure electric vehicle TransitConnect, with a top speed of 121km/h and a full-charged driving distance of 129km. This product is also used in CODA electric vehicles. A peak torque of 300 Nm can be transmitted, and a high input rotation speed of 14000 rpm. Due to the use of splash-free lubrication with oil-free pumps, the structure is simple and its mass is only 28kg.

BorgWarner unveiled the variable valve timing technology for the first time at this auto show. By adjusting the amount of intake and exhaust gas, and the opening and closing time of the intake and exhaust valves, the angle of air to enter was optimized to improve the combustion efficiency. However, this conventional technology consumes a lot of energy from the engine, making the engine speed torque insufficient.

To continuously improve power, fuel economy and reduce emissions. BorgWarner unveiled the variable valve timing technology for the first time at this auto show. By adjusting the amount of intake and exhaust gas, and the opening and closing time of the intake and exhaust valves, the angle of air to enter was optimized to improve the combustion efficiency. However, this conventional technology consumes a lot of energy from the engine, making the engine speed torque insufficient. BorgWarner has developed an innovative method of adjusting camshaft phasing: the use of alternating camshaft torque does not stop or shut the hydraulic valve to adjust camshaft phasing. Improve fuel economy by reducing power loss, boosting power, and helping clean engine combustion.
