Intelligent Engines The New Generation Machines Today the world needs engines that can cope up with the stringent emission norms and higher demands for robust, reliable and smart engines with low operational cost. To achieve the above possibilities, a whole new generation of engine is being developed with a comprehensive use of electronics, hardware andoftware in large 2 stroke low speed cross head engines known as “Intelligent” Engines”. The Intelligent engine concept widens the riability of traditional engines to facilitate new applications and concepts. The initial cost of such engine is quite high but the operational cost is lower than other engine used with proper operating procedure and trained crew. The frist intelligent engine in the maritime world was delivered in October-1998 and was introduced in a chemical carrier M/T Bow Cecil.

Basic Concept of Intelligent Engine 1. A central electronics control system is incorporated which is the brain of the system and which monitors And evaluate the general condition to keep the operating parameter within limits and maintain the performance of the engine at the higher side. 2. Central control system operates Engine control unit (ECU) and cylinder control unit (CCU). 3. ECU controls the overall protection and efficient performance of the whole engine. CCU control the each cylinder of the engine for safe and efficient working. 4. This control system saves the engine from damage due to overloading, malfunctioning maladjustment and lack of maintenance. 5. The Intelligent engine provides flexibility in operation by replacing mechanical cam shaft for fuel pump and exhaust valve with common rail
