But the faster the air flow and the less aerodynamic the object, the more the air flow breaks away and becomes turbulent. Direct air capture technology is intended to strip the carbon dioxide out. At low speeds, the air flows splits when it meets an object and, providing the object is reasonably aerodynamic, flows right around it, closely following its outline. More information on Cadillac can be found at . Scientists have been capturing carbon dioxide for decades, especially from highly concentrated sources, like power plants. In recent years, Cadillac has engineered a historic renaissance led by artful engineering and advanced technology. My dad, an engineer himself, helped guide me toward an automotive career.”Ĭadillac has been a leading luxury auto brand since 1902. “When I was younger, I liked to build things. “I’ve always been mechanically inclined,” she said. These acoustic treatments cover the instrument panel, center console, engine compartment and wheel wells.Īs chief engineer for the SRX, Pilibosian is responsible for performance and testing, a role that suits her wrench-in-hand personality. Engineers countered that with a variety of soundproofing materials. This provides greater confidence for passing and freeway maneuvers and an overall driving experience more responsive to driver input.Ĭonventional wisdom would suggest that larger engines are louder, given that 308 horses under the hood can make a lot of noise. SRX drivers will notice less shifting of the automatic transmission and more torque across a broader range of engine speeds, rotations per minute or RPM. This means more torque when you need it most.” “From larger diameter pipes to a higher-volume muffler, the system is tuned to pull exhaust gases out of the engine at 1,200 to 3,000 RPM. Electrohydrodynamic direct-writing (EDW) is a developing technology for high-resolution printing. “It’s all-new from the engine to the exhaust outlets,” Kline said. The exhaust system improvements are extensive. By increasing air intake capacity, Kline said, cooler and denser air is available to the engine, making it more powerful and responsive – especially on hot days in slow city traffic. “We wanted to continue our evolution of the SRX by improving the power and acceleration response of the vehicle,” said Steve Kline, lead development engineer. “They came back and exceeded the goal with 308 horsepower.”Įngineers made key engine changes and redesigned air induction and exhaust systems to get more horsepower and torque, the twisting force that gets a vehicle moving and what the driver feels when accelerating. “When we started planning to equip this vehicle with the 3.6L engine, I challenged our engineers to achieve 300 horsepower and maintain fuel efficiency,” said Liz Pilibosian, vehicle chief engineer. The new engine is standard on all SRX models sold in North America. DETROIT – It wasn’t a breeze, but redesigning the air induction and exhaust systems in the 3.6L direct-injected V-6 engine helps give the 2012 Cadillac SRX the most standard power in its crossover segment.
