Jima Y385T powered Mazda Pickup

danthefamilyman · Nov 2, 2006

Hi everyone. I wanted to post an update on the Jinma Mazda Pickup. It has now been on the road now for over a year. I now have 21,000 miles on the engine. It is still running great. My head gasket leak has gotten better, it still leaks a little but it doesn't seem to hurt anything. I am driving the truck to work everyday and on business trips. I just got back from taking it to Timberline Lodge on Mt Hood (Elevation 4500+ ft) it ran great. I will keep everyone posted as I continue to drive this truck. I figure I have between 600-800 hours on the engine.

I burned up a glow plug last month, so I robbed one from my Jinma 284 tractor until I got a new one. It sure is nice to have the same engine in my tractor.

No new problems to report. I still am running a stock Fram oil filter on the engine (Its the same filter that fit the orginal Mazda engine) and I don't have to add oil between changes (I change oil every 1500 to 2000 miles).

Thanks,
-Dan-

Hey Dan,

Congratulations,, and I think that it is just great,, that the 385 YangDong Engine is doing so well.

Please keep us updated on how everything is doing,, as time goes by.

Have a nice day,
Joe

Hey Dan.
Im very impressed with what you have done on this project, it seems very detailed and excellently done.
I have also been using the Y385 engines but not in a vehicle but rather mounted on some trucks to power my hot water pressure washers.
I use the engines to power a 5-7.5kw gen head and a cat pump that pts out 10 gpm at 3000 psi. We have also been running a blend of diesel and WVO and it smells and rund great.
I just read all of the posts and hopped with all that youve done with this engine if you could help me figure out how to add a tach to my engine?
Im also looking for a chart that shows me the power curve for this engine.

Great Project, Dan!! I love this!!

I used to work for a diesel engine manufacturer, and am familiar with the Bosch in-line pumps similar to those on the Jinma. There is a control rack in the pump, when it moves forward, you get more fuel. There is a screw, probably inside a cover, on the back of the pump. That screw turned just a 16th or 1/8th of a turn will be all you need!

As far as putting on a turbo, if you just put one on, your air/fuel ratio will be off. To really run right, if you add a turbo, you will need to add fuel as well.

I wouldn't be so concerned with power and torque curves, you really want the BSFC curve. You then set the gearing up such that most of the driving is done such that the engine rpm operates at the lowest point on that curve. That will get you your maximum efficiency. Typically a BSFC curve on a diesel looks like a 'U'. You want to run at the bottom, so someone mentioned about running it at 2000 rpm got them better fuel consumption. Aboslutely! I would expect exactly that. The only catch with doing that is to ensure you have enough torque there and you're not overworking the engine.

The other thing to adjust to make it more user friendly for the street is the end regulation. A highway application would have 15% but construction/agricultural equipment has 7%, and at the opposite end of the spectrum, a generator would have 0%......

Just my $.02.....great project, and keep us posted. I like the chinese tractor due to price, but have reservations about quality/reliability. If you get a 100k miles out of it, I think I'd be fine with a tractor!!

Dan,

I forgot to ask - I am dying to know how you balanced the flywheel!

I have a 9 x 20 LeBlond lathe and like to do that type of stuff.

Thanks,

Mike

Hi everyone!

Sorry I have not posted for a few months, I have been busy with new projects. I have been building a Biodiesel offgrid power plant for my home. It is just about done. I will post pictures of it this fall.

Update on the Jinma Powered Mazda Pickup:
I now have 31,000 miles on it and in September it will be two years that I have been driving it daily. It is running great, no new problems to report. I think the engine has about 1000 hrs now. My opnion of the Jinma / Yangdong engine is very positive. I don't believe that the average tractor owner would live long enough to wear one of these out. This is one tough little engine!! I have been running it flat out at 2700 to 3000 rpm wide open throttle for two years now with no ill effects.

Some thoughts on Bio-diesel:
I have been running 100% Bio-Diesel for the last year and a half. The engine runs fine with it, with only a slight reduction in power. The only thing that I have found is that it clogs fuel filters. Last summer I was replacing the primary fuel filter every two weeks. (it got old really quick) I now replaced the primary fuel filter with a huge filter (it holds over a quart) and now I should only have to replace it once a year.

I am committed to bio diesel on a number of fronts: It smells better both in the fuel tank and out the exhaust, it cleans up off of your hands wih soap and water, It has far better emissions than regular diesel, it lubricates better than diesel, and it has little to nothing to do with OPEC.

I also have been running 100% biodiesel in my Jinma 284 tractor as well for the last year, but I have noticed that I have some slight fuel leaks in the fuel lines from the tank to the pump. I think that maybe the fuel lines are not the type that resist Biodiesel.

Also....
I found a automotive oil filter that works on the Jinma / Yangdong engine, it is a FRAM PH3593A
They are very common and cost less than $4.00 ea
I have changed my oil more than 20 times over the last two years using this filter and have had no problems with it.
It is smaller in size than the stock filter but it is still a great filter.
I change the oil every 2000 to 3000 miles (estimated 70 - 100 hrs)

I will have more posts over the next few weeks, I would love to hear from you guys

Thanks,
-Dan-

Sounds Great Dan
What engine are you using for your generator?

Ron

danthefamilyman · Aug 2, 2007

It is a Listeriod 6 H.P. open flywheel (the brand name is Fu King). It is a crank start single cylinder open flywheel engine, driving a modified 5 KW generator head that has been modified to produce 48 Volts D.C. (for charging a large 48 volt battery pack)

Thanks,
