Development of a cost and fuel-efficient split engine

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，停用汽缸可以减少内燃机的燃料消耗。非燃烧汽缸的摩擦损失仍然存在。因此，机械上分为两个单独的内燃机的内燃机，在燃油经济性方面有更高的潜力。该研究项目的目标是开发一种经济高效的分燃发动机，由两台耦合的部分燃烧发动机组成。中心连接元件是一个可切换的联轴器，用于辅助发动机的负载相关激活。通过对两个工作子电机和离合器采用合适的操作策略，可以实现额外的燃油节约。

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.
