Combustion engines can not start working without being helped first to reach a minimum of speed rotation, this starter inertia is provided by external starters. These external starters are denominated "Engine Starters". This minimum speed rotation power, which would allow the operational working of the engine, must be enough for the main engine to develope the torque to overcome the resistance of internal friction (engine characteristics, indoor and outdoor temperatures, viscosity of the lubricant, etc).
The Engine Starter has the function to spin a gear motor called flywheel, which after finishing a turn, synchronized to the ignition system will start the engine. After starting the main engine, the Engine Starter returns to its initial or original position.
IPU has 2 types of Engines Starters beyond the conventionals (electrics) which provide the required torque for starting small and large diesel engines to be used in machinery work, land, sea and offshore. These types are: pneumatic or spring. Within these two types there is a specific variety of models to suit customer needs: whether for cost, safety, power, or work environments maintaining in all cases the reliability.
