At Lindholmen’s technical high school in Gothenburg, the mechanics and repairmen of the future are trained. In the school’s machine lab, specially equipped ship engines with state-of-the-art emission control provide students with unique opportunities to gain hands-on experiences in maintaining, troubleshooting and repairing engines \u2013 under realistic but supervised conditions. Diesel Power was entrusted to supply and install the equipment.  <\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

The requirements of the procurement were demanding \u2013 both on the equipment and on the supplier’s competence. The goal was to create a machine lab where engines can function and students can work exactly like in a real ship environment \u2013 however placed on dry land.<\/p>\n\n\n\n

Service-friendly Kohler units<\/strong><\/h2>\n\n\n\n

The main equipment in the machine lab is two generator units from Kohler, which are normally used to generate electricity on ships. <\/p>\n\n\n\n

Each cylinder has a separate cylinder head, which is an advantage in teaching, and the generator units are started with different types of ignition: one has an electric starter and the other has been equipped with an air starter from Gali. This allows students to learn how to handle both start-up methods. The engines can run at full charge in the lab. \r\n<\/p>\n\n\n\n

With the future in mind<\/strong><\/h2>\n\n\n\n

EcoPar is used as a fuel for the machines, a very clean fuel based on synthetic paraffin oils. EcoPar is free from both sulfur and aromatic hydrocarbons and thus smells much less than standard diesel \u2013 which results in a good working environment in the lab. \r\n\r\n<\/p>\n\n\n\n

Compared to conventional diesel, the climate impact is also reduced: carbon dioxide emissions are halved and NOx levels are reduced by up to 60 %.<\/p>\n\n\n\n

<\/div>\n\n\n\n

AdBlue finishing for minimal emissions<\/strong><\/h2>\n\n\n\n

The engines are equipped with an advanced exhaust aftertreatment system that meets industrial EU Stage 5, the emission requirements of which are significantly stricter than those applied at sea.\r\n<\/p>\n\n\n\n

The low emission levels are achieved through selective catalytic reduction (SCR), where AdBlue is added before the exhaust gases reach the catalyst. AdBlue is a mixture of water and urea, a nitrogenous and completely harmless chemical compound also known as a urine substance. \r\n<\/p>\n\n\n\n

The liquid helps to break down the harmful nitrogen oxides in the exhaust fumes to water vapour and nitrogen. NOx emissions do not exceed 0.4 g\/kWh and the post-treatment also reduces the amount of soot particles by 98 %.\r\n<\/p>\n\n\n\n

High-level cooling<\/strong><\/h2>\n\n\n\n

The cooling water from the engines is pumped up onto the school roof, where the heat is emitted \u2013 26 meters above ground level.<\/p>\n\n\n\n

Motor paws vs. concrete slab: 1-0<\/strong><\/h2>\n\n\n\n

On board a cargo ship, engine vibrations tend not to be a major problem for the crew. But in a property, noise and vibration can resonate in the building in a disturbing way.\r\n<\/p>\n\n\n\n

Since the base foundation in the machine lab was not suitable for ship engines in operation, Diesel Power developed a solution based on vibratec engine paws that effectively isolates the vibrations.\r\n<\/p>\n\n\n\n
