A range of advanced two-stroke engines offering low-emission potential for future commercial application have been compared in terms of their technological developments and unique features. An analysis where published data have been available has provided an interesting comparison of each different approach to meet future two-stroke cycle engine design objectives. While the two-stroke engine offers high-power-density and low-cost advantages, greater complexity and hence increased unit cost is inevitable in order to meet ever more stringent emission standards. By application of direct-injection systems, high-speed poppet valve actuation, active exhaust gas recirculation control to enable a wide range of HCCI operation, and variable-compression-ratio technology, the two-stroke engine still has the potential to provide competitive low-emission powertrain solutions. Direct injection is now a requirement for any modem automotive two-stroke engine. The relative ease of application of variable-compression-ratio operation to the twostroke engine should not be overlooked and offers interesting prospects for future research and development. Further development of engines such as the Ricardo 2/4 Sight and Lotus OMNIVORE therefore have strong potential; however, in order to address the challenge to minimize the unit cost, the stepped piston engine offers strong future prospects. Each of these engine types can present strong solutions for future engine downsizing.
