Reciprocating internal combustion engines - Performance - Part 4. Speed
1 Scope
GB/T 6072 provisions of this part of the grading system requirements and speed reciprocating internal combustion parameters, as well as the typical engine speed operation
Terms and definitions. Special engine applications may impose additional requirements.
GB/T 6072 This section applies to land use, marine and railway traction reciprocating internal combustion engine, but does not include driving road construction machinery, earthmoving machines
Machinery, agricultural and industrial tractors, road vehicles and aircraft engines, does not include self-tuning of the engine and requires only limit the maximum speed or
The maximum amount of engine oil.
GB/T 6072 This section provides compression ignition engines (diesel) at the request of spark-ignition engines and dual-fuel engine
You can make special requests.
Note 1. The performance and parameters of reciprocating internal combustion engine alternator for governor See GB/T 2820.2 and GB/T 2820.5.
Note 2. The terms and definitions of typical engine speed and overspeed protection device relating See GB/T 6072.6.
2 Terms, definitions, symbols and subscript
The following terms, definitions, symbols and subscript are applicable to this document.
NOTE. See terms and definitions related to speeding apparatus GB/T 6072.6.

2.1.1
Engine governor enginespeedgovernor
In particular engine operating conditions, actual speed and the speed ratio setting right, right amount of fuel to enter the engine is corrected to adjust
The actual engine speed to approach the speed setting means.
Note 1. Refer to GB/T 6809.7-2009 3.1.1.
Note 2. The governor according to the following classification.
a) by the speed sensor and output signal amplification (see GB/T 6809.7-2009,3.3.1);
b) Press the dynamic characteristics (transfer function) (see GB/T 6809.7-2009,3.6.2);
c) by use of the engine-related functions (see GB/T 6809.7-2009,3.3.3).
2.1.2
Speed \u200b\u200bsetting means speed-settingdevice
Use according to category or desired adjustment, adjustable means governor set point.
NOTE. rewrite GB/T 6809.7-2009, the definition of 3.1.2.
