What is fullform of NVH?
The NVH department of a motor car manufacturer, are concerned with making cars quiet and smooth so not stressful to drive. Noise, Vibration and Harshness.
Can engine mount be filled with oil?
Some OEM motor mounts like for BMW's have oil in them to reduce (NVH) noise, vibration,harshness. They are not serviceable, if they leak.. they should need replacing.
Why are used C4 Chevrolet Corvettes so cheap?
Because they are not nearly as good of cars as the C5s. On the plus side, a good one is a very fast car and easy on gas. The 85 and up cars are great performers. The LT1-4 cars are really excellent all around. Nothing you can do about the ergonomics and NVH.
How big is a Kia Optima?
The 2011 Optima is distinctive, right down to its all-new platform. Optima's low, lean and powerful stance is assisted through its overall length of 190.7 inches, an increase of 1.7 inches over the previous model. Optima is built on a platform with an overall width of 72 inches and wheelbase of 110 inches, an increase of 2.9 inches, and has a low ground clearance of 5.3 inches for enhanced aerodynamics. Optima's lightweight design uses high-tensile-strength steel to enhance structural strength while also achieving high torsional stiffness, benefiting handling, ride quality and refinement. Additional measures to help ensure good noise vibration and harshness (NVH) reduction qualities are fitted throughout the Optima. Built on a unibody frame, the front-wheel-drive Optima utilizes independent front and rear suspension systems. MacPherson struts are used in the front with a multi-link layout in the rear and are both joined with coil springs and front anti-roll bars to engage drivers with responsive handling and provide the utmost comfort whether the road is smooth or less than ideal.
How is noise reduced in a car?
Customers are beginning to make greater demands for quieter automobiles, and because of this, automakers have begun to attack sound inside the passenger compartment with greater ferocity. Thanks to advanced engineering capabilities and improvements in materials technologies, what used to be thought of as an uncontrollable source of unwanted sound is now fair game in the quest to reduce interior noise. From front and side windshields, to tire wells and the engine compartment itself, nothing has been left unexplored when it comes to finding new ways to ensure a quieter driving experience. "There is an increased sensitivity toward noise, from a personal standpoint and a societal standpoint," says Daniel Maguire, technical director--active systems, at Cooper Standard. "You see increasing links between noise and vibration and fatigue, noise and hearing loss. There is a technical interest coming about, and you also have personal interest. In the very high-end vehicles especially, it's clear that the companies are devoting significant effort in the development of the vehicle to minimize the noise and vibration harshness that exists in these vehicles. And that is something that is of late. When you look at a high-end vehicle and consider the amount of attention and money that is spent on the vehicle's ride quality and NVH characteristics, it is significant and very well representative of the importance that you see." Cooper Standard's product line includes passive and active vibration control components that are intended to reduce both vibration and the noises created by the vibration within the vehicle.
Why are my brakes chattering on a 1995 Chevy Monte Carlo?
Since you already have chatter have the rotors checked Leading cause of chatterLug Nut TorqueOver-torque of wheel lug nuts is one of the prime causes of brake rotor distortion. This can lead to permanent warping of the rotors, uneven wear of the rotors and pads and lots of brake chatter (NVH). With today's very stiff alloy wheels, like from BBS, SSR, Volk, etc., when you torque down the lug nuts the wheel-mounting surface will force what ever it contacts to take its shape. Which means whatever that surface looks like will be what the rotor looks like. Get a torque wrench and check the torques on every lug nut and make sure they are within the specs (which you should be able to find in your owner's manual). And make sure that every lug nut is torqued down exactly the same. Even if all 5 on a wheel are within specs, not having all 5 be equal will introduce distortion. And if you think that your light alloy wheel can't possibly be that stiff, you wrong they are MUCH stiffer than the brake rotor or even the hub. WORD OF CAUTION: Don't assume that torque the lugs to the lowest range in the spec is the best. Try and keep it nominal not at the extremes of the range. Much of the problems with rotor warp, brake chatter, disk thickness variation can be traced back to over-torque and uneven torqued lug nuts. After coming back from the shop, get that torque wrench and check the lug nuts yourself.
