The Yanmar N18 engine was officially launched in 1996 as the smallest engine from Yanmar’s N series of latest medium-speed diesel engines at the time. The N18 engine was developed primarily as a compact auxiliary engine for medium to large sized commercial vessels such as containers and cargo vessels. With a cylinder bore size of 180 mm and a stroke of 280 mm, the N18 engine produces power in the range of 400 kW to 660 kW, with a crankshaft speed of about 750 rpm to 900 rpm. The Yanmar N18 engines were one of the most compact medium-speed diesel engines at the time of their launch and that made them a very popular auxiliary engine choice among vessel owners. The N18 engines also feature advanced combustion systems for fuel efficiency and are compatible with HFO and MDO. The N18 engines have N and V variants. Both are in-line engine configurations but feature differences in some parts with the most notable example being the pistons – flat top for the N type and valve pockets on the top for the V type. 

Production of N18 engines has been stopped by Yanmar, with engines being made only on specific orders from shipowners. But there are still many N18 engines active on vessels sailing in Asia and Europe. And that is where Alang Maritime can help out, especially when it comes to original engine components. As an independent Yanmar specialist, we have a large stock of Yanmar N18 original parts and we have access to unused surplus of N18 engine parts from decommissioned vessels and trusted local suppliers.
