Engine Housing Components Crossword Puzzle

QUESTIONS LIST:

• wet liners : cylinder block liners that have direct contact with the water jacket and therefore must support cylinder combustion pressures and seal the coolant to which they are exposed.
• template torque : procedure used on torque-to-yield fasteners that usually involves torquing to a specified value with a torque wrench followed by turning the fastener through an arc of a specified number of degrees measured by a protractor or template
• oil pan : the oil sump, normally flange-mounted directly under the engine cylinder block.
• gasket : a physical seal between a pair of clamped mating faces.
• dry liners : liners that are fitted either with fractional looseness or fractional interference that dissipate cylinder heat to the cylinder block bore and have no direct contact with the water jacket.
• parent bore : term used to describe an engine with integral cylinder bores machined directly into the cylinder block
• fire rings : normally used to refer to the fixed ring that may be integral with the cylinder head gasket responsible for sealing the cylinder.
• creep : describes the independent movement of two components clamped by fasteners when they have different coefficients of thermal expansion or have different mass, which means their expansion and contraction rates do not concur.
• scavenging pump : usually refers to a secondary oil pump in an engine lube circuit that provides redundancy
• cylinder block : the main frame of any engine to which all the other components are attached.
• cavitation : describes metal erosion caused by the formation and subsequent collapse of vapor pockets (bubbles) produced by physical pulsing into a liquid, such as that of a wet liner against the wall of coolant that surrounds it.
• intake manifold : the piping that is responsible for directing intake air into the engine cylinders; clamped to the intake tract flange faces.
• exhaust manifold : the cast-iron or steel component bolted to the cylinder exhaust tracts responsible for delivering end gases to the turbocharger and the exhaust system.
• crankcase : the lower portion of the engine cylinder block in which the crankshaft is mounted and under which is the lubrication oil sump.
• cylinder head : the component clamped to a cylinder block containing the engine breathing and fueling control mechanisms.
• interference fit : the fitting of two components so that the outside dimension of the inner component fractionally exceeds the inside dimension of the outer component.
