needle cage: In a needle bearing, there are many rollers within a holder or cage. neg: Abbreviation for "negotiable," as in the price is neg. Also it may refer to the negative terminal of a battery, or negative ground. negative camber: See camber. negative caster: See caster. negative connections: Connections in an electric circuit through which the current flows back to its source. negative ground: An electrical system where the chassis is the negative side of the circuit and a separate wire to each component is the positive (hot) line. See ground and positive ground. negative load base: If the center of the payload is behind the rear axle, it is negative and takes load off the front axle. See load base. negative offset steering: A steering system which indicates the placement of the wheels. From the back of the vehicle, it appears as though the tires are tucked in where they contact the road. Although this system may appear strange, it actually does provide the benefit of helping a vehicle to stop in a straight line when the brakes are weak or the road friction is different on one side than the other. negative pole: The point toward which an electrical current flows through the circuit. It is designated by a minus sign (-). negative terminal: That terminal (such as that on the battery) from which the current flows on its path to the positive terminal. neon tube: An electric "bulb" or tube filled with a rare gas, used on ignition test instruments like timing lights. neoprene: A hard plastic like substance. net horsepower: See SAE net horsepower. net sales value: the selling price received by the manufacturer for the vehicle including the cost of transporting the vehicle in Canada (includes mark-up). neutral: The neutral position of a transmission is the gear position where the engine is unable to drive the wheels. It is usually placed between reverse and one of the forward gears in automatic transmissions; and is located centrally in manual transmissions. neutral flame: Flame which results from combustion of perfect proportions of oxygen and the welding gas. neutral steer: The characteristic of a vehicle's slip angles where both front and rear are the same. In slippery conditions, both the front and rear tires will break loose at the same time so that the vehicle slides sideways rather than the rear end swinging around (oversteer) or the front end wanting to move to the rear (understeer). A cornering condition in which the front and rear slip angles are roughly the same. Although seemingly an ideal state of balance, perfect neutral steer is not as stable as slight understeer. neutron: A neutral charge particle forming part of an atom. new car dealer: major car dealership with a parts and service operation. newton: A unit of force. One newton is the force which acts on a mass of 1 kilogram to produce an acceleration of 1 metre per second per second. newton meter: See newton metre as the standard spelling. newton metre: (Nm) A unit of torque. One pounds-force feet (lb-ft) equals 1.356 Newton metres. One Newton metre equals 0.7375 lb-ft. newton's law: For every action there is an equal, and opposite reaction. new tread: A term used by some tire companies to denote a retreaded tire. Also called "nu-tread." nibbling: The jerking action which occurs in a vehicle, due to the distortion within some tires as they are forced to traverse pavement ridges at a slight angle. nipple: A small metal piece that fits through a wheel rim of a bicycle and is threaded inside to receive the end of a spoke. nitrogen oxide: See nitrogen oxides. nitrogen oxides: In the combustion process, nitrogen from the air combines with oxygen to form nitrogen oxides. nitrous oxide: (NOx) One of the three basic pollutants found in the exhaust emission of an internal combustion engine. The amount of NOx usually varies in an inverse proportion to the amount of HC and CO. Nm: Acronym for "newton metre. NMA: Acronym for "The National Motorists Association" no fault insurance: A form of vehicle accident insurance in which the insurance company of each driver pays for the damages of its own driver regardless of who is at fault. So if you and I have an accident, my insurance company will pay for my damaged car and your insurance company will pay for your damages. nomad: See Chevrolet Nomad. nominal rim diameter: A measurement from one bead seat to the opposite bead seat 180° away. nominal rim width: A measurement between the flanges at the bead seat. non-directional tread: An arrangement of bars, grooves and ribs in a manner that gives equal traction in forward or reverse direction. Also see directional tire and directional tread. nonferrous metal: A metal which contains no iron (except in very minute quantities). Thus it is not subject to rusting. nonferrous metals: All metals containing no iron (except in very minute quantities). Thus they are not subject to rusting. normally aspirated: An engine that intakes air or "breathes" without the assistance of a supercharger or turbocharger. normally aspirated engine: An engine which uses the factory installed carburetor or fuel injection system with its normal air filter, etc. It does not use modified air flow systems which pump more air into the engine. Usually this expression is used as comparison as in My modified intake puts out more horsepower than a normally aspirated engine. NORS: Acronym for "new old replacement stock," or "new old reproduction stock." These are parts that were aftermarket replacements, usually of the same quality, for the manufacturer's parts. Or, they are parts that were reproduced by an aftermarket supplier using the same quality of materials and manufacture as the original manufacturer, but now are "old." north American Free Trade Agreement: (NAFTA) Agreement creating free trade among the United States, Canada, and Mexico. The NAFTA went into effect on January 1, 1994. north American Industrial Classification System: (NAICS) Industry Classification between Canada, the United States and Mexico to increase compatibility of data with these countries. The classification is based on establishment rather than commodity. This classification system will be implemented with reference to year 1997 and data will be available in 1999. north American produced: motor vehicles assembled in Canada, the United States or Mexico. north pole: The magnetic pole in a magnet from which the lines of force emanate; travel is from North to South pole. NOS: Acronym for "new old stock." These are parts that originally were available from the manufacturer of an automobile. They have never been used, thus are "new." But they also may have been on the shelf for decades, thus are "old." NOx: Oxides of nitrogen. They are at their worst when combustion is most efficient. They are produced because the air is 78 percent nitrogen. Combines with HC in sunlight to form photochemical smog. NOx emissions can be reduced by lowering peak combustion temperatures through lowering compression ratios and by recirculating exhaust gases. nozzle: A thin hollow tube. See fuel injector nozzle. notchback: A body shape which differs from a fast back. When a fastback is observed from the side, there is a smooth line (curve) along the roof from the A-pillar to the back of the car. In a notchback, the roof is abruptly dropped down to the leading part of the rear deck (or trunk). NSPA: National Standard Parts Association. NSU: The 1964 Wankel Spyder models are milestone cars. NTF: Acronym for "notify." When a mail order seller does not have the merchandise in stock, but expects to get it in the future, he tells a customer the item's status with "NTF," which means he will notify the buyer when it is in stock. nuclear: Involving the inner part of an atom, the nucleus. Changes in the nucleus can release a lot of energy which can be used in the generation of power. number drill: See number drills. number drills: A series of drills in which each size is designated by a number (0-80). nut: [1] A fastening device that is roughly doughnut shaped with a number of flat surfaces on the outer rim and threads on the inner hole. Also see bolt and nut, butterfly nut, castellated nut, lug nut, and wing nut. [2] A person who is greatly interested in a field such as "Jim is a car nut." Also see buff. nut cover: A cap or covering over a nut to protect it or to improve appearance. nu-tread: See new tread. nylon: A synthetic fiber which is stronger than vinyl. |
