Transmission to the fleet of MRK Vyshny Volochek delayed due to problems with the Chinese engine
According to him, the delay is caused by problems with high-speed marine diesel engine CHD622V20 produced by China.
Engineers are now in close collaboration with fleet fix problems. In the near future, elements of a two-stage turbocharging system will come and eliminate the shortcomings, he added.
According to the original project, the German MTU 16V4000M90 engines planned to supply all nine ships of the Buyanov-M series under construction. However, due to the cessation of supply caused by the sanctions, MTU diesel engines were installed on only five ships transferred to the fleet in 2014 – 2015.
On the remaining ships of the series, the command of the Navy decided to put Chinese diesel engines - 20-cylinder CHD622V20 with a power of 3200 kW.
According to the chief designer of the M150 diesel engine, Pulsar PJSC Zvezda, Alexander Arkhipov, the engine from the People's Republic of China for 21631 ships is a licensed copy of the German diesel engine Deutz TBD622, while the manufacturer Deutz-MWM has already left the market.
A source in one of the engine-building companies, familiar with the situation, told the publication that the engine CHD622V20 did not fully meet the requirements for the power plant of a warship.
He stressed that the Chinese diesel compared to MTU, which managed to put on the first "Buyan-M", less reliable and consumes more fuel.
