Info on The New Ford Ranger's NVH


Ford is busily promoting the new Ford Ranger. This time I've received a press release of the Ranger's NVH statistics that would make interesting reading and viewing ...on your tablet or smartphone that you are looking at whilst waiting for something to be done like baking a cake, waiting for a connecting flight or sitting in the lavatory or just waiting for somebody to arrive. 




PRESS RELEASE
Quiet Confidence: The New Ford Ranger 

In the world of modern pickup trucks, being a tough and capable work vehicle is the cost of

entry. To stand apart from the crowd, a new truck has to combine the rugged performance

customers need with the comfort, refinement and quietness they and their passengers want.

Engineers took a hard look at the previous Ranger – already among the most refined pickups on

the market – and worked on solutions to improve noise, vibration and harshness (NVH) even

further. “The new Ranger is a step up across all NVH metrics,” said Nick Lovadina, NVH

supervisor for the new Ford Ranger.

The improvements are not just for bragging rights: Reduced cabin noise can help to reduce

driver fatigue on long journeys.

Some of the solutions implemented on the new Ranger include:

 Sound-deadening materials: Special materials, like a dense insulating felt under the

hood on some models, help to reduce powertrain, wind and road noise, making for a

quieter cabin

 Engine management improvements: Updates to the engine management system help

to improve diesel performance and efficiency. Precise injection timing and calibration

means more efficient performance and less combustion crackle for less powertrain noise

 Smart aerodynamic design: Aerodynamics engineers added small aerodynamic “sails”

on the wing mirrors to significantly reduce low-frequency throbbing noise created when

driving with one front window open

 Hydro mounts: The new Ranger uses hydraulically damped engine mounts on some

models to effectively combat engine vibrations. Filled with hydraulic fluid, these are

particularly effective at reducing low-frequency vibrations created by diesel engines.

“The hydro mount engine mounting system is not only an advantage for the key NVH metrics of

idle, start-up and acceleration, but also helps to improve overall vehicle dynamics,” said

Lovadina. “The customer ultimately has a truck that feels more refined than ever before.”

The efforts of Lovadina’s team resulted in a Ranger that is just 5 dB louder in the cabin at idle

than a humming refrigerator, and just 5 dB louder at 80 km/h than rainfall.

“The combination of the refined powertrain and the improvements we’ve made through actions

like sound deadening make for an extremely quiet, stress-free driving experience at highway

speeds and in typical everyday city driving for all occupants,” said Lovadina.
