1engine-indicating and crew-alerting system — A flight deck display system that displays engine operating data on a cathode ray tube console, thereby eliminating the need for conventional engine instruments. In the event of a malfunction, the flight crew’s attention is drawn to the data,… …
2Engine balance — is the design, construction and tuning of an engine to run smoothly. Engine balance reduces vibration and other stresses, and may improve the performance, efficiency, cost of ownership and reliability of the engine, as well as reducing the stress …
3Secondary air injection — Theory and origins= Secondary air injection (commonly air injection, colloquially smog pump, trademark Air Injection Reactor) is an automobile emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream.… …
4secondary nozzle/exhaust nozzle — An annular nozzle surrounding the primary nozzle of a jet engine. A cooling airflow passes through the secondary nozzle. Separate secondary for fan flow and core engine flow …
5secondary fan airflow — That part of the airflow through a fan that does not pass through the engine core. This airflow is used for cooling the engine and in some cases for afterburning. See secondary air/airflow …
6secondary compression — A term that is used in two stroke engines. Primary compression takes place in the crankcase and is then pushed up into the combustion chamber where secondary compression takes place as the piston squeezes the mixture. If the crankcase seals are… …
7secondary fuel — The main fuel flow from fuel nozzles. The fuel that flows at higher power settings as opposed to the primary or pilot fuel, which is used for starting the engine and/or low engine speed operation. See primary fuel (i) …
8secondary air/airflow — That portion of the compressor output air used to cool engine parts and combustion gases. See also primary air …
9Extensible Storage Engine — For JET Red storage engine of Microsoft Access, see Microsoft Jet Database Engine. For the teacher s term, Exceptional education. Extensible Storage Engine (ESE), also known as JET Blue, is an Indexed Sequential Access Method (ISAM) data storage… …
10V6 engine — A V6 engine is a V engine with six cylinders mounted on the crankcase in two banks of three cylinders, usually set at either a right angle or an acute angle to each other, with all six pistons driving a common crankshaft. It is the second most… …
