A diesel engine is an engine that burns diesel for energy release. It was invented in 1892 by German inventor Rudolf Diesel. In order to facilitate production management and use, uniform regulations have been made on the compilation method of the names and models of diesel generator sets.
The old model diesel engine production rules are as follows:
Header 1: Replacement or improvement symbol (given by the manufacturer): H is the replacement high; G is the supercharged in the improvement; A, B- is the improvement symbol
Middle 1: Number of cylinders i: Represented by numbers
Middle part 2: Cylinder arrangement type symbol: V-V cloth: L in a row (can be omitted)
Middle 3: Cylinder diameter (190mm)
Rear 1: Type code: unsigned single unit; P supporting unit (with base, fan and radiator)
Rear 2: Structural feature symbols: unsigned—non-supercharged; Z—supercharged; ZL—supercharged, intercooled
Rear part 3: Structural feature symbols: unsigned – non-supercharged; Z – supercharged; ZL – supercharged, intercooled
Rear part 4: Use symbols: No symbol—mechanical driving drilling rig, general purpose; D—electric driving drilling rig, power generation; C—marine right engine (Cz — marine left engine); J — locomotive traction; G — other construction machinery
Note: When different performance structures are used for the same purpose, the number sequence number in the lower right corner of the purpose symbol is finely noted, such as: C1, C2, D1, D2
Rear 5: Fuel symbol: no symbol – diesel engine; T – natural gas engine; s – dual fuel engine; M – gas engine; Z – biogas engine
Tail 1: Speed symbol: unsigned -1500r/min; 1-1200r/min; 2-1000r/min; 3-1300t/min; 4-900r/min
Tail 2: Turn sign: unsigned – turn left; R – turn right
