    Yanmar 12AYM-WGT; The High Speed Marine Engine that Makes 1,822 hp and 6,300 lb-ft of Torque

    Yanmar is a manufacturer of high-speed commercial marine diesel engines, and the 12AYM-WGT is its largest, highest-output powerplant for seagoing vessels. With 1,822 hp and 6,300 lb-ft of torque, this workhorse provides ample power for ships to carry out their required duties, and still maintain stable cruising speeds under load. The abundance of low-rpm torque, thanks to the use of a long piston stroke, makes the 12AYM-WGT very well suited for use in tugboat applications, where large amounts of grunt are needed.

    This engine is designed to be tough and reliable, and it will provide economical, clean power (it meets 2016’s emission standards). Yanmar is able to do this with a development that it calls EcoDiesel Technology, which does not use any electronic engine controls to govern emissions. The management is done mechanically, to avoid failures caused by electronics’ exposure to engine-compartment heat. The EcoDiesel technology concentrates on the engine’s combustion process. Improvements of the combustion conditions in the cylinder lead to a reduction in fuel consumption, smoke and NOx emissions. Normally, when trying to reduce NOx, fuel usage and exhaust output are negatively affected. But, the Eco Diesel’s more efficient combustion comes from the use of fuel injectors with multiple micro-sized holes, deeper combustion chambers and reshaped 4–valve-per-cylinder heads. This new efficiency also provides the engine with increased service intervals as well as horsepower and torque gains.

    The 12AYM-WGT is Yanmar’s largest high-speed commercial marine engine. Its 1,800 hp and 6,300 lb-ft allow working ships to operate quickly, economically and in compliance with emission standards.

    A boost compensator, which regulates the air/fuel mixture in each cylinder, helps reduce black smoke and fuel consumption under hard acceleration. An internal EGR system is used to further lower emissions. The EGR is controlled by the lift of intake and exhaust valves, which eliminates the need for external control devices. The engine’s design provides a fuel economy gain of 53 gallons of fuel per hour over older models, and allows the 12AYM-WGT to meet Tier II emissions standards. The engine is expected to meet Tier III standards by 2017.

    Engines that are used in marine settings need to be durable and serviceable. Yanmar addresses durability in a couple of ways. Sillicard, an artificial ceramic made from silicon carbide that’s second only to diamonds in hardness, coats the surface of the cylinder liners to make them tough and resistant to wear. The liners are then paired with ductile cast-iron pistons that use a nitride stainless steel ring with very tight tolerances.

    The engine uses two heavy-duty injection pumps instead of one to improve serviceability in the fuel system. This allows for each bank of injectors on the V-12 to have its own pump (the pumps are sourced from Yanmar’s marine six-cylinder engines).

    The engine block has large inspection windows on the side of the casting, which allows ease of piston replacement. Another innovative design used on the 12AYM-WGT is the use of individual heads for each cylinder. The unique configuration facilitates easier repairs.

    The twin turbochargers and air-to-water intercooler are mounted on the rear of the engine so exhaust can be easily routed out of the vessel.

    Building marine diesels is nothing new for Yanmar. The company built its first engine over 90 years ago. That powerplant had low compression and burned fuel oil, which doesn’t support much horsepower, instead of diesel. However, by continuing to innovate, Yanmar has become the maker of very efficient, high-powered marine-diesel engines

    I hope that catches on. Electronics renders equipment unserviceable.

    I had to look up the max RPM: 1940 RPM.

    I wonder why the compression ratio is only 13.2 to one.

    good question Howdy,

    I think the turbos are helping in that regard?

    They didn't say what the boost was either. I'll bet 4 or 5 bar

    Turbo diesels have lower compression ratios than naturally aspirated diesels. For example a given naturally aspirated diesel engine with 20 to one compression ratio would be 17 to one if turbo's. Still....13.2 to one? Seems it would take some fast cranking to start it.

    Compression ratio numbers are based on mechanical ratio and don't take into effect turbo boost.

    YANMAR DIESEL ENGINE Type HE
    20hp/450rpm
    Around 1938
    Manufacturer : YAMAOKA Internal Combustion Machines Ltd.
    Manufacturer's Location : Chayamachi, Kita-ku, Osaka-shi, Osaka, Japan

    At first a sound hearing lively is a sound from the engines of the neighbors. The exhaust of the type HE is exhausted calmly to express a sigh after having hit a silencer.

    This Engine is not my thing. I observed this engine at 2013 HAKUBA engine shows.

    Container Ship Main Engine Starting
    Engineering



    Published on Jan 18, 2014
    This video shows how to operate the main engine (94rpm max) of a container ship from the emergency manoeuvring station (engine side control console).

    The engine is started using compressed air which pushes the pistons down in sequence to bring the speed up before fuel is injected.

    In this video the large hand wheel is used to regulate the rack and slide operation of all of the engine's fuel pumps which control the amount of fuel entering the cylinders and so, the speed of the engine.

    Main Engine Man B&W 12K98MC
    - 12 Straight cylinders in-line
    - 980mm Bore
    - 2660mm Stroke
    - 68640 kW (92048 hp) @ 94 rpm

    True story. The longest lasting engines I've ever known were inline sixes. Two Waukesha 1197's with 65K hours and a 3406 Cat with 80K hours, original rod and main bearings and piston rings.

    And the worst application was to use a 2 stroke diesel in a truck
    Those things bled more oil than they consumed, great acceleration though

    and talk about fun...runaway

    My 8v92 starts like that. Love it when when folks are standing next to my truck on the the ferry and I star up to unload.....


    What's the problem? I have two 2 strokes. 671 and the 8v92. Don't have to change the oil and I keep the dust down on my road! (lol)
