gemischzulaufung

Gemischzulaufung, also known as mixed-flow combustion, is a type of combustion process used in internal combustion engines, particularly in diesel engines. In this system, the fuel and air are mixed before they enter the combustion chamber. This is in contrast to direct injection systems, where fuel is injected directly into the combustion chamber.

The primary advantage of gemischzulaufung is its simplicity and reliability. The fuel-air mixture is prepared in a separate chamber, which can be optimized for efficient mixing and combustion. This can lead to more complete combustion and reduced emissions compared to direct injection systems.

However, gemischzulaufung also has some disadvantages. The mixing process can be less efficient than direct injection, leading to potential fuel wastage. Additionally, the fuel-air mixture must be prepared at the correct ratio for efficient combustion, which can be challenging to achieve under all operating conditions.

Gemischzulaufung is commonly used in older diesel engines and in some modern engines where simplicity and reliability are prioritized over fuel efficiency. It is also used in some types of gas engines, where it is known as the "mixed charge" system.
