What Do the Numbers on an Engine Model Represent?
1 Answers
Engine model numbers represent relevant information about the engine's manufacturing enterprise, specifications, performance, characteristics, technology, purpose, and production batch. Prefix: Includes the product series code, generation symbol, and regional or enterprise code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standard regulatory body. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder bore. Suffix: Comprises symbols for structural features and intended use. Tail: Distinguishing symbol. When differentiation is required within the same product series due to improvements or other reasons, manufacturers may select appropriate symbols. The suffix and tail sections can be separated by a "-".
