combining fuel economy and low emission rates with high fuel versatility. The shortest and lowest engine in its class, the Wartsila 26 requires minimum space in the engine room. Wartsila works in close co-operation with its customers when conducting field tests and monitoring selected test components. This has resulted in satisfied customers: 720 engines have been manufactured or are on order since the new design in 1996. With fewer parts, lower maintenance requirements, low fuel consumption, less emissions, and the ability to run reliably on a variety of fuels, the Wartsila 26 is unquestionably...

PISTON AND PISTON RINGS The piston design consists of a forged steel crown and nodular cast iron skirt with pressurized skirt lubrication. The three-ring pack comprises two ceramic chromium-plated compression rings and an oil distributor ring. This ring pack ensures optimum pressure distribution and reduces lubricating oil consumption. The combustion chamber ensures efficient combustion at all loads, while the component temperatures are kept low. CONNECTING ROD The connecting rod has a horizontally-split bottom end to obtain minimal length and high rigidity. It has only one single drilled hole, without...

MAIN BEARING The geometry of the main bearing creates an oil film thickness which greatly exceeds the safety margins set by the bearing manufacturers, in accordance with the ‘Thick Pad' philosophy of Wartsila. The studs and nuts of the bearing caps are hydraulically tensioned. CRANKSHAFT Special attention has been given to optimizing the various geometrical characteristics, such as cylinder distance, to achieve a space-saving solution. Three-dimensional finite-element analysis has been used to achieve the optimal result with maximum overall rigidity and moderate bearing loads. All criteria of...

CYLINDER LINER WITH ANTI-POLISHING RING Flanged liner with tangential water flow, and symmetrically supported at the top. Antipolishing ring removes the carbon from the top land of the piston, thereby preventing liner polishing. This system results in a drastic reduction of cylinder wear, lower lubricating oil consumption and a clean piston. CYLINDER HEAD The use of four cylinder head studs offers easy access for maintenance, while requiring less space. Rigidity of the cylinder head design ensures adequate and uniform sealing between cylinder head and liner. Rigidity of the flame plate prohibits deformation...

FUEL SYSTEM Fuel feed and return lines are Integrated In the fuel pump housing. This results in fewer pipe connections and therefore high reliability. Shielded high-pressure lines and the ‘hot box' design contribute to safety, especially in heavy fuel operation, The pressure pulses in the low-pressure system are very low, FUEL INJECTION SYSTEM The Wartsila 26 fuel injection system achieves the optimum fuel spray pattern and droplet size, Proper dimensioning of the camshaft, camshaft bearings and rollers ensures long lifetimes and low maintenance costs, ENGINE-DRIVEN PUMPS Engine-driven lubricating...

MAINTENANCE The design features of the engine facilitate direct access to the vital parts. This cuts the time needed for maintenance. Other key aspects of easy maintenance include: • Minimized number of parts by combining several functionalities in the same componenet • Hydraulic tensioning of the studs for the cylinder head, connecting rod and main bearings • Automatic lubricating oil filter • Easy removal of the cylinder head
