Royal Oak-based RTT USA Inc. said this week that it is helping customers of the Warrenville, Ill. heavy truck equipment maker Navistar see inside the newest Navistar MaxxForce 15-liter diesel engine with RTT’s three-dimensional photorealistic animation.

The animation was first used to showcase the engine to attendees at the 2011 Con Expo in Las Vegas and the 2011 Mid-America Trucking Show in Louisville.

“RTT created an animation to highlight the engine’s internal components in action — components that would be near impossible for customers to visualize on a physical model,” said Peter Stevenson, co-CEO of RTT. “This is where 3D visualization really works because it allows companies like Navistar to travel with their product — even a heavy duty truck engine  — allowing for effective on-site sales.”

Six main engine components were brought to life in the animation:
* Fuel System: An inside look at the high-pressure fuel system illustrates the engine’s combustion cycle: air intake, fuel spray, combustion and exhaust.
* Pistons: The animation visualizes how fuel is sprayed and atomized into the piston bowl — a new feature Navistar designed to evenly distribute fuel into the cylinder, resulting in more complete burn and increased power and efficiency with less exhaust.
* Turbocharger: The outer components are peeled away to expose air-flow in the small and large twin turbochargers. The smaller primary turbo responds quickly for immediate acceleration at low speeds, while the larger provides peak power at highway speeds and on steep grades.
* Exhaust Gas Recirculation Valve: The engine’s floating core helps to eliminate torsion stress and heat cycling, extending component life. The animated butterfly valve eliminates a spring system that could comprise function.
* Isolated Oil Pan: The MaxxForce 15L uses an isolated oil pan to reduce engine noise.
* Engine Brake: The animation ghosts back the valve to expose and animate the engine brake as it transitions from a dormant to operational position. This feature gives the MaxxForce 15L the highest braking horsepower of any engine brake in its class.

The end result is more than a photorealistic animation for one-time use. The images created by RTT can be leveraged across all media platforms with the opportunity to be repurposed for sales, training and marketing — providing continued time and cost savings.

“Navistar’s MaxxForce engines are unique in how they utilize 3D technology to tell a story within their product,” added Stevenson. “That’s what makes RTT’s technology so beneficial to this industry. If customers look at the MaxxForce engine line up, each one of the products has something different to say, and RTT helps them communicate it in a way everyone can clearly understand — through animated, realistic imagery.”

The MaxxForce 15L engine recently received 2010 emissions certification from the EPA and the California Air Resources Board.
