Description / Abstract:
Application of this Code is limited to engine assemblies as
defined in Pars. 1.3.2 and 1.3.3.
Code Engine Assembly. In the absence of specified stipulations the engine assembly to be tested shall consist of the engine complete with essential apparatus for self-sustained continuous operation. Generally these consist of the equipment required for: fuel introduction; air induction (i.e., scavenging or supercharging); ignition; lubrication; and primary engine and charge-air cooling. This is termed the "Code Engine Assembly."
Specifically, a "Code Engine Assembly" includes apparatus: a) to control, carburet or inject fuel delivered to it at required operating supply pressure, including booster fuel supply pump or compressor when attached to engine; b) to provide injection air or gas (if engine is of the air- or gas-injection type); c) to compress intake air; d) to provide ignition; e) to circulate lubricating oil throughout the engine lubricating system, including oil cooler, strainers, filters and mechanical force feed supply; and f) to circulate the primary coolants through the engine jackets, lubricating oil coolers, and intake air coolers - all as involved in the engine assembly being tested.
If any apparatus required for the above functions is driven by a separate source of power, the power input to, or the fuel consumed by, the driving unit shall be charged against the "Code Engine Assembly." If any apparatus, systems or parasitic load not included in the "Code Engine Assembly" (such as an intake filter, exhaust silencer, or radiator system) is attached to or driven by the engine, it should be detached during engine tests, or, if detachment is not practicable, the power consumed thereby shall be separately determined or agreed upon and credited to the "Code Engine Assembly" power output.
The "Code Engine Assembly" does not include any apparatus for starting, battery charging, or other purpose which does not function continuously, nor any apparatus for other purposes not mentioned here.
Specified Engine Assembly
Purpose
This Code provides rules for testing, and for the computation and tabulation of theresults of tests, for all types of reciprocating internal-combustion engines, in order to determine power and fuel consumption.
