Combustion chamber for motor vehicle internal combustion engine has insulating inserts in cylinder head and piston crown

摘要

The combustion chamber for a motor vehicle internal combustion engine is formed between the cylinder head (2), a cylinder (3) and a piston head (5). It has a cylindrical thermal shield (4) cast in the head to form the valve seats (10), and a piston crown, both forming thermal shields. The piston crown can have a thermal shield fixed to the top of the piston.
