Found in many diesel-powered vessels of all kinds, a Four-Stroke Diesel Engine is a type of engine that is so named because it requires that the piston complete four strokes while turning a crankshaft in order for internal combustion to occur. As the engine reciprocates, the piston moves up and down the cylinder twice, with the crankshaft revolving twice. The heat of the engine is then transferred to the fuel at constant pressure. The four strokes required for this process are the Induction or Intake Stroke, the Compression Stroke, the Power or Combustion stroke, and the Exhaust Stroke. 1. The Induction or Intake Stroke During…

The sea provides endless enjoyment for diesel powered vessel owners all over the world. But as beautiful as the open ocean is, it can be equally as dangerous and unpredictable for the initiated and uninitiated alike. Whether it is a novice or seasoned veteran behind the wheel, the ocean makes no discrimination with its violent power. Even the most experienced seafarers can find themselves caught off guard by inclement weather, navigational miscalculation, mechanical problems, or a nearly infinite number of other unexpected problem scenarios. No one is immune to the water’s mystery and power. That is why regardless of experience or skill level, there are…

In our ever-changing economic climate, no detail can be overlooked when performing maintenance on your vessel’s engine. Even if you’re using high quality MTU parts in your marine diesel engine, one overlooked detail can mean the difference between a pleasurable hobby and an economic liability. Making sure that each individual system of your marine diesel engine is performing optimally is the best way to maintain its overall functionality and longevity. It is important know that many components have changed since the clunky diesel engines of years-gone-by. In an effort to both improve performance and lower the level of harmful emissions, most modern diesel fuels now contain…

As the 21st century moves along at a lightning pace, we find ourselves in a constant state of motion. Whether by ground, sea, or air, the methods that we use to get from place to place, or just enjoy the freedom of being behind the wheel are constantly evolving. Long gone are the days of wanton vehicular waste – where once the miles of freeway constantly clouded by a blackened haze of filthy emissions were the everyday routine, most now feel need for a fuel solution that is both more reliable and environmentally responsible than the noisy, cloud-spewing options of the past. Even diesel engines,…

The MTU maintenance system for their products is based upon a preventive maintenance concept. With advanced planning, preventive maintenance ensures a high level of equipment dependability. The load profile/load factor of your MTU equipment determines the maintenance schedule to be used. The time intervals at which the maintenance work is to be done, along with the tasks and relevant checks involved are average values based on operational experience and should be regarded as guidelines only. Technical requirements and special operating conditions may require additional modification of the maintenance intervals and /or maintenance work. In order to carry out the individual maintenance, using authorized personnel, such…
