  • Season 3 Episode 9. Jimbo modifies the injector pump timing on the turbo diesel then takes the car out to measure the performance. Next Jimbo adjust the boost from 10 psi to 12 psi and once again measure the performance change. How do these modifications effect the fuel economy?... well Jimbo finds out by taking the car on a fuel economy run. Tune in and check it out!

    Switching to electronic boost control might help with your lag in boost when changing gears. Especially if you were to use an interruption-style controller. That stops the actuator from seeing any boost pressure at all until you want it to. That can have a massive effect on spool-up time.

    Think you should add a duct or a scoop if that's how you mounted the intercooler, with it sticking out upwards like that it has more turbulance than airflow and it will do as much as a passive cooler.

    As for the ring gap, it may actually be ok for the turbo. I’m not sure about kubota, or if this engine also has a turbocharged option in a different application. Other tractor manufacturers use the exact same shortblock with or without a turbo, so they set the ring gap for turbos no matter if the engine gets one when installed or not.

    I have an additional engine idea for the Renault as well. You mentioned that you would like the GEO Metro 3 cylinder engine, but it is difficult to find. There are actually several alternatives and also some interesting small diesel alternatives as well. One is the Mitsubishi Mirage 3 cylinder. This engine is still in production and makes almost 80 horsepower from the factory. They are fairly easy to find. Another is the Briggs and Stratton/Daihatsu 3 cylinder liquid cooled engines. There are gasoline, turbodiesel, and non turbo diesel 3 versions available. The Kohler liquid cooled diesels are also attractive options, such as the KDW1003, used in the Polaris Ranger 1000. The Canadian 799cc om660 Smart Car diesel is another engine which may be the best option out of all of these next to the Mitsubishi Mirage 3 cylinder. It makes about 40 horsepower but can be tuned to make more power than that, meaning that stock, it would have identical power output to the stock Renault engine. It may be more difficult to get, as it has to be shipped down from Canada, but I think it would make an awesome engine swap. Another weird but cheap option would be to swap in one of the Chinese V-twin yanmar diesel clones. This would be a similar swap to the Predator 420 in the Insight, but diesel. Those engines are also very cheap for a brand new engine with the disadvantage that you have to wait for the shipping from China. One additional crazy idea would be to swap in a motorcycle engine or jetski engine, something with a lot of power at high RPM. Maybe a Yamaha 600CC or similar, or even one of the Kawasaki STX jetski engines.

    Propane injection. Excellent content. I did prototype diesel engine testing for many years. Diesels have Exhaust Gas Recirculation for a reason. The charge cooler is heat soaked because of the mounting on a large steel bracket. More instrumentation is key and data logging real time not relying on video sync errors. More temperature and pressure sensors. I wish I could see the car in person. You're really pushing that engine hard. Don't be afraid to blow it up.
    The head gasket is going to be your failure point usually into the coolant passages. NOx is created during lean run conditions. You're not producing smoke as far as I can tell so you're far from too rich. Wide band AFR or Lambda sensors? I want to see that little engine do sub 20 sec 0-60 times.

    I think it is a result of all of the above. I used to have a diesel jetta, same engine you are planning on putting in your insight. I advanced the pump timing to around 10 degrees before top dead center and turned up the injection pump which resulted in much more power, enough that it completely removed all the friction material from factory clutch disk I had just installed so I had to upgrade, and a huge increase in fuel economy. .

    I enjoy the whole diesel Saturn series chap. I consider you give it a name so it wouldn't be forgotten by time. I got a name for yours, the Saturn 720TDI (it would be more green for eco-guys with a tiny green "ECO" sticker)
    But, really, this conversion is astonishing.
    The Prius did around 40 - 50 MPG
    The Saturn 720TDI did around 58 - 59 MPG with 720cc engine which modified with a Turbocompressor, an Intercooler, and fuel injection pump adjustment.
    The 0-60 time is not important when you wanted a car that only drives you from A to B with certain experience of the car.
    I like cars (well, some of it, not all cars) especially if it had a diesel engine and of course manual transmissioned, but mainly I like trucks (not the trucks referred to many US people, but truck in the whole world or in UK you said lorry) and buses (with diesel engines), so the 0-60 time is not going to matter me.
    What I personally love about this Diesel Saturn series is the sound of diesel engine, a real diesel engine.
    Don't convert this Saturn to EV, please.

  • @ProDigit80
    @ProDigit80 Před rokem +3

    My only complaint would be, that the 700cc should be making a lot more power out of the box. If you look at a 4 cyl 1.4l turbo diesel car engine, they make 150hp, so you'd think that an engine like this should max out at 70-75hp. But this one barely makes half the power. There's got to be some other reason why. More than likely, the engine is tuned (ported) to provide low rpm torque, and with a low compression ratio from the factory (as these engines are made to run 24/7 for years on end, and prefer reliability).
    For a car, you can increase compression, meaning lower longevity for higher performance. If not, increase the boost, which has a similar effect. Exhaust temps should never hit 1k F on this engine. It might not get enough cooling.
    Most road worthy diesel cars are required to run DEF fluid next to the ULSD fuel. If this engine has a way to add DEF, it would cool exhaust temps. You don't even need to run DEF (Urea). You can very easily just inject distilled water in the air intake, which adds torque, decreases exhaust temps, and somewhat protects the environment (better than with no DEF fluid).

    Love this project! I think the next big thing would be hybrid setup... add a couple (cheapish batteries that can unload huge power fast, but low AH) and a electric motor (that also can unload a lot of power lets say 200 kw) and make some thingy (with a button :-) so that you can use it for 10s just accelerate to 60 MPH and then use the kubota for the cruise. Siphon some (could be a cheapish solar charger maybe) power of the generator back to the smallish batteries so in 2-3h :-) you could use the electric again for accelerations :-)
    Just did some rough calculations... 🙂
    200 AH 12v battery for 10s if you can unload everything though is about 1 228 KW in 10s (or 1646 HP).
    So I think you can get 200 HP easily for 10s with 200 AH battery (or many smaller in parallel) then ofc get a good controller/frequency converter and a engine to match...
    Homebuilt, cheap hybrid that is fast and really great fuel economy :-) or maybe just get the new Prius :-)

  • @joec9680
    @joec9680 Před rokem +1

    I’m gonna give you the recipe for max safe power for your setup. First step is to completely stop the wastegate from opening and turn fueling up a lot or as much as you can go. At this point you can melt that motor straight into the ground if your stupid. Drive it and slowly lay into the throttle. What your looking to get out of this test is the maximum boost number. You will see at some point boost will no longer rise with throttle input but egt’s will keep climbing. At this point you need to tune your wastegate. To accomplish this you want to find where the turbo will make the peak boost with the wastegate opening at that point. I normally back off the boost till I see 1 psi below max and then adjust it back to max boost. Now you adjust overall fueling. When in boost and full throttle you should not have egt’s higher than 1150 if you want to be completely safe. You can go to 1250 and probably be ok but I would just stick with 1150. Biggest issue you have is that your injection pump isn’t setup for boost reference. I’d bet you max out that turbo before you run out of fuel.

    Little anecdote on the fuel economy increase. I have a turbodiesel Jetta, and most people report increased fuel economy after doing turbo and injector upgrades. This seemed backwards from what I thought would happen so I did some digging trying to figure it out. It seems the common theory is that by making more power, you spend less time accelerating, and that is when you consume the most fuel. Seems logical to me but definitely counterintuitive to what I've always thought.

    The Cummins NTC-855 engine can be tweaked very significantly by altering the injector timing. Yes its bad nor NOx, but it really wakes them up. There was a version called the NTA-475 made by Cummins which had variable timing on the injectors......problem was they used a design of mechanism that had a bad tendency to seize up and cause problems.......but when they were working properly, they went 'hard' in heavy trucks. 12psi of boost is way off where it needs to be............20psi at least. Dont worry too much about the durability issue...........that engine is meant to do 30,000 hours as a fridge compressor engine........and its not being lugged full throttle for extended periods of time. You only need piston oilers when a turbo diesel is going to do high load factors.

    The best way to reduce the exhaust temperature is to put larger diameter exhaust pipes and remove the muffler system to reduce back pressure, the higher the exhaust pressure, the higher the temperature will be, and the larger the pipe, the lower the pressure, and thus temperature. Also have you considered an exhaust cooler system? A simple copper pipe coiled around the exhaust manifold and filled with coolant that is sent to a separate radiator can reduce exhaust temp significantly

    I think fitting a fan under the intercooler, along with some simple ducting to blow air from below, up out the scoop would both pass more air over the intercooler, but also keep the engine bay temps, meaning cooler air temps for the turbo. Even if only slightly.
