Improving fuel economy and reducing CO2 emissions is an important issue for car and engine manufacturers. It is known that cylinder deactivation can reduce the fuel consumption of an internal combustion engine. Friction losses of the non-firing cylinders still remain.Therefore, internal combustion engines, which are mechanically divided into two individual combustion engines, promise an even higher potential in terms of fuel economy.The objective of the research project is to develop a cost-effective and fuel-efficient split-combustion engine consisting of two coupled partial combustion engines. Central connecting element is a switchable coupling for load-dependent activation of the secondary engine. Additional fuel savings can be achieved by a suitable operating strategy for the two working sub-motors and the clutch.

提高燃油经济性和减少二氧化碳排放是汽车和发动机制造商面临的一个重要问题。众所周知，停缸可以降低内燃机的燃料消耗。非点火气缸的摩擦损失仍然存在。因此，在机械上分为两个单独的燃烧发动机的内燃机在燃油经济性方面具有更高的潜力。该研究项目的目标是开发一种由两个耦合的部分燃烧发动机组成的具有成本效益和燃油效率的分体燃烧发动机。中央连接元件是一个可切换的联轴器，用于根据负载启动辅助发动机。通过对两个工作子电机和离合器采用合适的操作策略，可以进一步节省燃油。
