integral seats and guides
Glossary “integral seats and guides” Definition:
Parts that are one with the head.
integral type power steering
Glossary “integral type power steering” Definition:
A steering system with a built-in power assist.
integral valve guide
Glossary “integral valve guide” Definition:
Valve guide machined into the cylinder head.
integral valve seat

intregral axle housing
Glossary “intregral axle housing” Definition:
A rear axle housing type in which the parts are serviced through an inspection cover and adjusted within and relative to the axle housing.
intake over exhaust (IOE)
Glossary “intake over exhaust (IOE)” Definition:
Engine design having intake valves in the cylinder head and exhaust valves in the block
intake ports
Glossary “intake ports” Definition:
1). Passages in the cylinder head that direct A/F mixture from the intake manifold to the intake valves. 2). Passages in an L-head engine block that direct the A/F mixture from the intake manifold to the intake valves. 3). Passages in the head or block of an injected engine that direct air to the intake valves from the intake manifold.
intake stroke
Glossary “intake stroke” Definition:
Downward stroke of a piston that draws the A/F mixture into the cylinder. The first stroke in the four-stroke cycle. Diesel engines only draw in air during this stroke.
intake valve
Glossary “intake valve” Definition:
Valve that opens to admit the A/F mixture.
integral
Glossary “integral” Definition:
Internal or built-in as a part of the whole.
intake air temperature sensor
Glossary “intake air temperature sensor” Definition:
IAT A thermistor device that senses intake air temperature by changing it’s resistance as a negative temperature coefficient resister.
intake manifold
Glossary “intake manifold” Definition:
Component used to duct: 1). The A/F mixture from the carburetor to the intake ports. 2). Air in an injected engine to the intake ports.
intake manifold vacuum
Glossary “intake manifold vacuum” Definition:
The pressure inside the intake manifold when the engine is operating.
insulator
Glossary “insulator” Definition:
1). Material with high electrical resistance that supports or separates conductors to prevent undesired flow of current to other objects. 2). Material that contains less than four electrons in its valance shell.
insulator ribs
Glossary “insulator ribs” Definition:
In a spark plug, unevenly spaced circular ridges on the upper section of the insulator to reduce or prevent flashover of the high voltage from the terminal to the lower shell.
INT
Glossary “INT” Definition:
Integrator (short term fuel trim)
intake
Glossary “intake” Definition:
Point at which a fluid or gas enters a pipe or channel. The act of taking in.
intake air
Glossary “intake air” Definition:
Air drawn through a filter and distributed to each cylinder for use in combustion.
