- Nibbler
- A tool used to cut sheet metal without deforming the sheet or causing a burr; works upwards, leaving the hands above the material; allows circular and straight cuts
- 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.
- Nibs
- Small indentations on the edge of the brake shoe lining table that contact the shoe support pads on the backing plate.
- Ni-Cad
- A rechargeable battery used in many high power light systems. Benefits include reasonable weight, good run times, and solid long-term durability.
- Ni-Cad rechargeable battery
- Used in many high power light systems. Benefits include reasonable weight, good run times, and solid long-term durability.
- NiCaSil
- Nickel-silicon plating used, for example, on the cylinder walls of certain light-weight high-performance engines to reduce weight and friction and improve heat transfer. May be spelled nikasil.

- Nickel
- A silver-white metal usually used as an alloy in steel, bronze, brass and cast iron. It tends to
increase corrosion resistance. It is added to 300 series stainless to provide corrosion resistance,
increased strength in both high and low temperatures, and increased toughness in low temperatures.
Nickel lowers the effects of work hardening, thus reducing traces of magnetism caused by cold forming
and making material flow more freely in manufacturing.

- Nickel metal hydride
- (NiMH) A rechargeable battery used in many light systems. Benefits include light weight, good run time for its weight, and reasonable long term durability
- Nifriding
- A surface hardening process used on ferrous metals by heating the metal in contact with ammonia gas or other nitrogenous material.
- Ninety-eight
-
A model of automobile produced by Oldsmobile from 1941 to 1996. The 1949 98 Holiday Hardtop is a milestone car.

- Nipple
-
- A fitting which is threaded to the end of a spoke. The nipple is seated in the holes of the rim and receive the threaded end of the spoke. The nipple has a slot at the top so that it can be quickly tightened a little, but the other end of the nipple has flat or square sides so that a spoke wrench can be applied to tighten the spoke into the nipple
- A small, one-way valve used for injecting grease into a bearing.
- A short, steel tube holding a thin rubber or plastic tube used for bleeding hydraulic fluid
- A short piece of threaded pipe used to connect two fittings.

- Nitriding
- The hardening of steel by heating it for several hours in ammonia gas. Used on crankshafts
- Nitrile rubber
- Also known as Buna-N rubbers, these adhesives have high strength, excellent aging properties and good chemical resistance, including resistance to both aliphatic and aromatic solvents and to most platicizers which cause bond failure of other adhesives. Nitrile has excellent resistance to petroleum oils and gasolines, to mineral and vegetable oils, but poor resistance to oxygenated solvents like acetone. It has good heat resistance and is the most commonly used adhesive material in applications exposed to hot oils
- Nitrocellulose paint
- A paint which gives a deep, lustrous finish. It is used on old Jaguars but was prone to crazing and checking. Because spraying with nitrocellulose paints creates environmental problems, they are no longer used for volume cars
- Nitrogen dioxide
- (NO2) A compound of nitrogen and oxygen formed by the oxidation of nitric oxide (NO) which is produced by the combustion of solid fuels. Mildly poisonous gas often found in smog or automobile exhaust fumes.
- Nitrogen oxides
- (NOx) In the Combustion process, nitrogen from the air combines with oxygen to form nitrogen oxides such as nitric oxide and nitrogen dioxide. Nitric oxide is the main oxide of nitrogen emitted in raw exhaust gas, typically 90%; nitric oxide and nitrogen dioxide are severely toxic gases without emission controls, the exhaust of an spark ignition engine contains 0.3-1.5 kg of NOx per 100 liters of gasoline consumption
- Nitrophyl
- A closed cell material that's impervious to gasoline and fuel additives; used as a float material
- 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.
- Nitrous oxide system
- A performance system that injects nitrous oxide into the inlet manifold at the press of a button, thereby introducing a quick dose of extra energy and a burst of power. On a 6-cylinder or V-8 engines, the nitrous oxide system is intended to add up to 250 HP; it consists basically of a pressurized nitrous oxide bottle as used for welding, solenoids, an injector base plate for the carburetor, and steel pipes; the low vaporization temperature of nitrous oxide (-90°C) cools the A/F charge, dampening detonation and minimizing stress caused by increased load
