Abstract

In order to improve the fuel economy of a vehicle engine, its cylinders are divided into two groups, which are operable independently of each other. The fuel system is adapted to supply either, or both groups with fuel. The crank shaft of one cylinder group is connectable to the power take-off shaft by means of conventional transmission and clutch means, while the crank shaft of the other cylinder group is connectable to the power take-off shaft by way of a transmission arrangement running in parallel to the row of cylinders, and comprising a shaft. The auxiliaries of the engine are mounted at the end of the engine remote from the power take-off shaft, and can be driven from either group of cylinders by way of the transmission arrangement.
