11D58M
11D58M is a restartable LOX/kerosene liquid rocket engine developed by TsKBEM and serially manufactured at Voronezh Mechanical Plant for DM-series upper stages. KBKhA lists Proton-K, Proton-M, Zenit-3SL and Zenit-3SLB applications and reports about 300 DM-series launches, with an improved combustion chamber, a multi-start scheme that reduces propellant losses during start and shutdown, new booster pump units, and increased reliability compared with 11D58. KBKhA states that engine manufacture for customer deliveries continues; the stored Zenit-3SL installation remains a single sourced example.
