RT-Flex - Intelligent engines
These engines are equipped with high pressure rails of fuel and oil (common rail) and electronic control.
Electronically controlled ME/ME-C engines
The essence of the engines from this group is based on automatic and hydraulic system of fuel injection activation and on the control of exhaust valves.
In 1956, a licence to build marine engines was purchased from Sulzer Brother Ltd., Switzerland (currently, Wärtsilä Switzerland Ltd.). In 1959, a similar licence was acquired from Burmeister & Wain, Denmark (currently, MAN Diesel A/S). The last steam engine (Ty 51) was delivered in 1958. Since then, more than 1,350 marine engines have been made at the Diesel Engines Factory HCP S.A. The L/S-MC, L/S-MC-C and RTA-U/B, RTA-T/B series have been especially appreciated in recent years.
Advantages of the produced engines:- Perfect matching of engine power and screw propeller shaft revolutions;
- Running on various kinds of petroleum fuel, from diesel oil to heavy fuels, viscosity up to 700 cSt/50°C;
- Easy installation;
- Low-stress and low-strain, compact and robust design;
- High operating reliability;
- Optimised temperature distribution ensuring relatively low thermal load levels;
- Optimised bearing load;
- Optimised exhausted valve design ensuring long-term reliable operation;
- Load-dependent cylinder liner lubrication system designed to optimise the lubricating oil supply to service conditions;
- High-capacity water separators in the forced induction air intake system;
- Low power demand of cooling and fuel supply system auxiliaries;
- Optional additional power takeoff directly from the crankshaft;
- Very high thermal efficiency (more than 50%), unmatched by any other power source;
- Easy maintenance;
- Designed for operation in automatic and unmanned plants;
- Long maintenance intervals.
All engines delivered by the Diesel Engines Factory HCP S.A. comply with the requirements of International Convention for Safety of Life at Sea (SOLAS), the requirements of IACS Classification Societies, and the IMO NOx emission requirements. The engines manufactured under either of the above-mentioned licences can be delivered with electronic fuel injection control. This solution provides a high-precision control of the engine's main operating variables to achieve the best performance characteristics, with optimised exhaust emissions, fuel consumptions and times between overhauls.
