3. DI Diesel engine cylinder head design
3.1 Design constraints to be taken into account
The architecture of the cylinder head will be directly impacted by a number of technical choices that need to be known before starting the actual design: material, timing drive, valve train, number of valves per cylinder, position of intake and exhaust manifolds, injection system, blow-by gas decanting system. In addition, the design must be coordinated with that of other parts of the engine, such as the crankcase.

Material
In the automotive industry, cylinder heads are made of light alloys, with a composition and metallurgical structure that limit the risk of cracking at high temperatures. The advantages of this material are lightness, castability (complex core...
