Introduction
The document discusses the development of ecological engines in the automotive, industrial, and marine sectors, driven by increasingly strict anti-pollution regulations. VM Motori has been at the forefront of this development since the early 1990s, implementing advanced solutions to limit exhaust emissions.

Technological Advancements
VM Motori has applied its experience in automotive diesel engines to industrial and marine engines, particularly with the introduction of Common Rail technology. This innovation has allowed the MR 500 and MR 700 series to increase power output while adhering to emission limits, maintaining reduced fuel consumption and reliability.

Compliance and Standards
All models comply with RCD and EPA TIER II directives, ensuring they meet current environmental standards.

Technical Specifications
The document provides detailed technical data for various engine models, including engine type, cylinder configuration, displacement, power, torque, and dimensions. The engines feature a 4-stroke diesel cycle with direct injection, electronically controlled Common Rail, turbocharging, and aftercooling.

Construction Features
Key features include freshwater cooling for exhaust manifolds and turbochargers, seawater cooling for lube oil systems, and heat exchangers for easy maintenance. The design minimizes external flexible pipes, and auxiliary devices are driven by a Poly-V belt.

Standard and Optional Equipment
Standard equipment includes SAE flywheel housing, starter motor, alternator, oil and fuel filters, and a freshwater engine cooling system. Optional equipment includes hydraulic reverse/reduction gear and a fly bridge dashboard.

Conclusion
VM Motori continues to innovate in engine technology, offering products that meet stringent environmental standards while satisfying customer requirements.
