Requirements to Vehicle Engine Prestart Processing Systems // Dvigatelestroyeniye. — 2009. Й 4. а. 15–19.
The article discusses possible methods and means of vehicle engine prestart heating, which assure engine start at negative ambient temperature with no support from external energy sources. Prestart heating systems featuring phase transition heat accumulators (PTHA) are considered in detail. PTHA are shown as contributing into better engine operation performance.

Breusov V.P., Kukolev M.I., Vildyaeva S.N., Abakshin A.Yu.
Externally Heated Engines // Dvigatelestroyeniye. — 2009., Й 4. а. 41–45.
Externally heated engines based on regenerative closed-loop cycle take undeservedly little place in engine building history. Stirling engine invented at the beginning of XIX century provides a number of benefits such as multi-fuel capacity, high fuel efficiency, environmental safety, and low noise. Nowadays scope of Stirling engine applications is pretty wide. Such engines are growingly used as autonomous environment-friendly power sources.
