Chevrolet Uses Liquid-Cooled Turbo in 2020 Silverado

Chevrolet is using new engine technology in the 2020 Silverado, designed to improve efficiency through water cooling.

The 3.0L DOHC inline-six diesel engine, producing 273 BHP and 460 lbs-ft of torque, features a liquid-cooled turbocharger has a low-friction ball-bearing shaft and is mounted close to the engine exhaust outlet, meaning there is quicker spool-up of the turbine, reducing turbo lag.

Meanwhile, the water-to-air intercooling system is able to produce more power since it has a cooler higher density air charge. Because water-to-air intercoolers are more efficient than the air-cooled counterparts, the intercooler can be smaller and lighter, meaning more space for other components and less weight to be driven.

Along with the low pressure exhaust gas recirculation – when exhaust gasses are recirculated to the engine cylinders, as a way of improving efficiency and reducing emissions – this reduces the time it takes to produce torque, since turbo lag is considerably reduced.
