3.7 ENGINE CATEGORY
An engine category is the means by which engines are grouped based on how the engine produces power.
Valid Values:
RECIPROCATING
ROTARY
TURBINE
OTHER
. A RECIPROCATING engine is an internal combustion engine in which the reciprocating (back and forth) motion of one or more pistons within their cylinder(s) due to combustion is converted either to the rotation of a crankshaft or to the rotation of the cylinders about a stationary crankshaft. Reciprocating engines operate with intermittent combustion.
. A ROTARY engine is an internal combustion engine in which the combustion is contained in a chamber formed by part of the housing and sealed in by one face of the rotor(s) working upon a crankshaft or other device to create rotational movement. Rotary engines operate with intermittent combustion. A rotary engine is also known as a Wankel engine.
. A TURBINE engine is an internal combustion engine in which gases from the combustion chamber(s) drive the blades of a turbine to create rotational motion. A turbine engine operates with continuous combustion.
. OTHER refers to an engine that is not a reciprocating, rotary, or turbine engine.
3.8 ENGINE SUB CATEGORY
An engine sub category is the means by which an engine category is subdivided based on similar design characteristics.
Valid Values:
TURBOJET
TURBOFAN
TURBOPROP
TURBOSHAFT
