Some Experiences of Two-Cycle Engines as Power Unit for a Passenger Car 650008

The main reason why SAAB has chosen a two-cycle engine as the power unit for its passenger car is the high output of this type of engine in relation to weight and displacement. In this paper, some special experiences from the power and reliability points of view are described, especially with regard to driving at low-temperature conditions. The significance of suitably chosen inlet, exhaust, and ignition systems, is treated together with the test programs undertaken to improve the reliability and life of the engine with regard to long, hard driving as well as stop-and-go driving in cold weather.
