- All-new Intake System Feeds Duramax Diesel on 2017 Silverado HD
- Cool, dry air delivers lower engine temperatures, maximum performance
Marked by a dramatic hood scoop, the all-new air intake system provides 60 percent of the air to the Duramax diesel engine from an inlet at the front of the hood. The air provided to the engine is very close to the outside ambient temperature and much cooler than the air under the hood.
Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. Running cooler allows the Duramax diesel to maintain full power and vehicle speed for capable trailering in even the toughest conditions.
“The 2017 Silverado HD was engineered to provide maximum utility for our customers in even the most extreme situations,” said Eric Stanczak, chief engineer, Silverado HD. “While developing this all-new induction system, we considered our customers towing a maximum-weight trailer through the Eisenhower Tunnel on a hot, rainy summer day.”
At more than 11,000 feet above sea level, the Eisenhower Tunnel, is the highest vehicle tunnel in the world and one of the highest elevations for any roadway in North America.
Testing the effectiveness of the system was rooted in real-world driving conditions of every degree — from misty rains to monsoon-level downpours; from powdery snow to wind-driven ice pellets; from desert dust to arctic cold.
Surprisingly, torrential downpours do not necessarily pose the biggest challenge, according to Kevin Dunn, global vehicle performance for splash engineering: “Big, heavy raindrops from a thunderstorm are relatively easy to eliminate from air. The more challenging issue comes from the mist-like spray generated by semitrucks on wet highways. Those very fine water droplets prove more challenging to separate from the air. The air intake is an elegant solution that works well with water droplets of all sizes. For customers, the results delivers maximum engine performance and even greater towing confidence.”
