The controllers are composed of control software, ADEM III ECM, sensors, fuel injectors, actuators, and an interface to the system. They are used to control Electronic Unit Projector (EUI) operated engines. The size of the cylinders directly influences the size of explosion inside them and by that determines the power of an engine.ĪDEM III Controllers are only used on select diesel engines where they act as the main Electronic Control Module (ECM).
Displacement is a measure of the volume of the engine’s cylinders which is also an indicator of the engine’s power and size. The Marine 3512B has an engine displacement of 51.8L (). Moreover, in heavy duty machines, this engine can run slower than smaller engines often resulting in prolonged engine life. One major advantage of this alignment is that it eliminates the need for balance shafts no matter the type of V-angle formed, primary and secondary balance is always perfect. All the 12 cylinders drive a common crankshaft. In most cases the cylinders are placed at angles of 60° to each other.
In the V-12 engine, 12 cylinders are mounted on the crankcase, usually in two planes of six cylinders each. This configuration reduces overall engine dimensions length, height and even weight, compared to inline configurations. Their pistons and cylinders are aligned in two separate planes to a form a V-shape when viewed from the axis of the crankshaft. V engines are some of the most sought-after internal combustion engine configurations. The Caterpillar 3512B Marine engine is a V-12, four-stroke Diesel propulsion set.
