SO 40.3 - Yanmar 4JH3E engine interface to NMEA2000

[nettuno]

Hi,

I have a Yanmar 4JH3E with the simple control panel (only tachometer, alarms and then a gauge with engine hours and another with fuel level) and I'd like to connect engine data to a Raymarine multidisplay I have available to read NMEA Data like:

• Engine Hours
• Engine RPM
• Oil Pressure
• Oil Temperature
• Coolant Pressure
• Coolant Temperature
• Percent engine load
• Battery voltage and current
• Alternator potential and current
• Total Fuel vol
• Total Fuel %
• Fuel rate

With those data and my Multifunction Display then I'll be able to setup:

• Est. Fuel Remaining
• Fuel Used (Trip)
• Distance To Empty
• Time to Empty
• Engine and transmission warnings and alarms


I'm thinking to add a Engine Gateway YDEG-04 from Yacht Devices: yachtdevicesus.com/products/engine-gateway-ydeg-04 with the Yanmar adapter cable: yachtdevicesus.com/products/adapter-cables-for-ydeg-04-engine-gateways

Anybody knows if the Engine transmit all those data by default? I should add additional Engine sensors to allow the engine to transmit all this data?

I think you are very ambitious here. Your list of the data you want includes a few items like fuel flow, that are very difficult to measure for a diesel engine, because the fuel is recirculated, and you have to measure both fuel TO the engine, as well as fuel BACK to the tank. You also may not have enough existing locations for all the sensors - oil temperature and coolant pressure come to mind as the first problems. In any case, you will have to add a LOT sensors, and then figure out how to convert their output to a common format that can be digitized. I am not sure how you will measure engine load - I guess you could just use throttle position or add a sensor to the fuel rack position. The alternator and battery measurements will each require a shunt.

I would love to have this info, but am too old to take it on as a project. I bet you could find a lot of people who have done at least a subset, and build off of their experience.

Good luck and let us know how it goes.

One last thought. How old is your engine and does it already have the sensors for this project? The website for the connector says it is for Yanmar 4JH engines, but I know that I don't have any connectors on my 4JH3-TE that could provide the necessary info.

Looks awesome to me, I have the Axion display, and this is just what i'm looking for.
Go for it and let me know how it works!!

This seems like a very ambitious undertaking. Voyageur has a Yanmar 4JH3E engine, but I don't believe that it uses a data bus to communicate with the control panel, but will check that. The manual for the interface device makes no mention of the Yanmar engine. And the interface adapter cable appears to be configured to tie into an existing data bus. So this may be a bigger effort than expected.

I'm not sure if the 4JH3E has the same CANBUS interface as the 4JH45, but this article:  jeanneau.proboards.com/thread/6257/yanmar-4jh45-engine-interface-raymarine discusses a solution.
I have not (yet) implemented the CANBUS interface, but it is on my TODO list.  From CANBUS, I'll go to my Raspberry PI which is able to interface to the Raymarine via SignalK (software) and YachtDevices gateway (YDWG-02).  This is more complicated using the YD Yanmar interface.

I look forward to hearing how this works out for you.

Did you get this working? I too would like more engine info on my raymarine display. How difficult was it? I don't even have engine hours!

Hi Rick, I didn't do it yet. I have it in my todo list. As soon as I have it I will share how it works

A bit different setup, but I installed the YDEG-04 from Yacht Devices along with their adapter cable to our Yanmar 4JH45 and B&G Zeus2 with a NMEA 2000 network. The adapter cable plugged into the service port on the back of the engine, and I had to run a NMEA 2000 cable with the right interface plugs to a nearby NMEA 2000 hub.  The installation was straight forward and the new data showed right up on the B&G MFD.  However then I learned that this does not keep track of fuel consumption.  For this I added the Fuel Data Manager from Lowrance/Simrad/B&G. Borrowing from the list from Nettuno, here is what I get:

• Engine Hours - yes
• Engine RPM - yes
• Oil Pressure - don't know.  I don't have a pressure sensor on our engine
• Oil Temperature - don't know
• Coolant Pressure - don't know
• Coolant Temperature - yes
• Percent engine load - yes
• Battery voltage and current - voltage yes, but not current.  Voltage was there before installing any of the above.
• Alternator potential and current - don't know
• Total Fuel vol - yes with Fuel Data Manager
• Total Fuel % - don't know if in %
• Fuel rate - yes, per hour and also per NM either based on SOG or STW

With those data and my Multifunction Display then I'll be able to setup:

• Est. Fuel Remaining - yes with Fuel Data Manager
• Fuel Used (Trip) - yes with Fuel Data Manager
• Distance To Empty - yes with Fuel Data Manager
• Time to Empty - don't know
• Engine and transmission warnings and alarms - don't know. These are still coming from the engine control panel in my case.

Hope this all helps a bit...

Cheers!

Hi Sunrise4, do you have a picture of the plug of the service port on the back of the engine? I'd be great to know if it's the same of the 4JH3E engine...

Thanks!

Nettuno, before I installed the YDEG-04 from Yacht Devices (with its adapter cable) the orange connector in the first picture was connected to the grey connector shown above the green connector.  These connectors are mounted on the side of the engine control unit (in my case on the starboard side of the engine and aft of the ECU).  Note that the grey receptacle connector has no wires attached to it as the orange connector I believe is just intended for diagnostic purposes. The back of the orange connector (I think it is called a 'Deutsch' type of connector) has 4 wires connected to it.  There is a green wire hidden behind the yellow wire in the picture.  The orange connector is then plugged into the Yacht Devices adapter cable and the other end of the adapter cable is plugged into the YDEG-04 device.

Note my engine is a Yanmar 4JH45, so your setup is likely different.

Hope this helps!

Hello
I am trying to do the same think.
Did you find a solution ?
Does it works ?
Thanks to share your exprience.

[wolferich]

Does someone try with a 4JH5E?

[wolferich]

I talked with YachtDevices in the meantime and they informed that the 4JH5E does not deliver the needed digital data.

Hi all

I know that it is an old thread, but trying my luck here

Anyone managed to install this in the 4JH3E engine?

if so, how?

I made the BIG mistake of taking the information from Yacht Devices as valid, and buying the Engine gateway and Yanmar adapter cable, as their documentation states that it is compatible with the 4JH engines, but I cannot figure out where to plug it now

Thanks in advance.
