Abstract
Lightweight design of diesel engines implies a suitable engine concept offering the highest possible torque characteristics and high performance within a given swept volume. Based on this assumption, a minimum total engine mass including all accessories must be achieved. Lightweight design fits in with the following conditions:
- Most compact exterior dimensions of the engine and the accessories in response to decreasing engine package spaces.
- Minimal principal dimensions, such as bore pitch and cylinder-head bolt spacing.
- Particularly for all moving parts, lightweight design is desirable to achieve favorable friction values and extended durability.
