Abstract
Abstract A drive assembly, particularly for driving a vehicle, comprises a driving engine and an auxiliary engine as well as auxiliary assemblies which can be selectively driven by one of the engines. In a clear frontal area of the vehicle engine, a single-bank radial engine constructed as an internal-combustion engine is arranged as the auxiliary engine to save space. For achieving a compact, high-powered arrangement, the single-bank radial engine is constructed as a 4-cylinder 2-stroke engine with a crank guide power unit.
