Better diesel engine, ISUZU or HYUNDAI?

[essjei55]

Ako lang mag isa boss and walang karga haha. Mostly -1 to 0.8km/l pag manual computation. So kung 6.2km/l yung ave. 6kph nasa 5.2 to 5.5km/l nga siya. Kala ko yung gasoline suv lang namin ganun uminom haha

That sucks to hear boss. I think mag iimprove pa naman yan. Iwasan mo na lang yung España route [emoji23][emoji23]

That's disappointing... I thought the MUX was really fuel efficient talaga.

The mux is. I don't know why his blue power isn't. Though mine is a euro 2.

it depends largely sa route and heaviness of the foot.

paayos nyo suspension ng Santa Fe nyo, preferably the lower ball joint, papalitan nyo na, that improved my FC. but of course I also changed the tie rod , rack end, stab links, stab bushings, and new tires hihi. avg FC is 9.5Km-10Km/liter

with the MUX bluepower, I observed that malakas sya pag ang PSI is 35 or less, make it 40 PSI, mali yun rating dyan sa sticker na sa door ng mUX.

basta ang tires nasa 44 PSI max, make it 40, minus 10% lagi.

even my gas guzzling explorer V6 improved at 6km/liter nun ginawa ko 40 psi. but of course, bago palit din lahat tie rod, rack end ball joint and new tires

Chill driving pa yan bro haha. Stop and go traffic is a factor. Q.ave rin is one of my route impossible mag stay sa 40 to 60 kph especially sa mga uturn slots and mga puv and pub na bigla nalang nag sweswerve to pick or drop passenger. Mas efficient talaga sa edsa kahit sabihin nilang sa EDSA LANG MAY FOREVER haha

From EDSA NB then left sa Quezon Ave. ito na route ko pauwi. Ok sana tumakbo dito until 60kph, problema dami nagswerve na mga sasakyan di magstay sa isang lane lang..

legacy or old school diesel may in fact be economical to modern common rails in some instances. may iba nagsasabi ng ganito. all you need is a single squirt of a few milligrams of diesel fuel for an old school diesel and compression. whereas, modern ECU controlled diesel engines may inject fuel in atomized form up to 7 times (typical) and then compression depending on the injection scheme. in multi injection, though also designed for fuel efficiency, it will have to satisfy other factors like reducing engine vibration, emission standards etc,. these take part of the fuel injected spent somewhere. consider this example, i have two bongos for utility use, both are same size, same engine almost identical. one is old school fired by an ordinary fuel pump the other is ecu driven. and my drivers would attest that the old school is a bit more economical under the same load conditions. okay, the old school is noisy and a little smoky in contrast to the ecu driven. i thought maybe their right foot should have the same behaviour then.

Plausible pero in some cases siguro but in general ECU controlled engines are precise and efficient compare sa non-ECU counterparts nila, hence walang waste ng fuel. The injection is monitored real time once the data or signals from the sensor are sent to the ECU. I work onboard ships, and ang mga main engines of the newer vessels that comes out from the shipyard now adays na ECU and VIT controlled are more efficient and has better consumption. Can run on low rpm without without any problems to the injectors when using bunker fuels on low load not to mention camless na din ang mga bagong main engines ng barko ngayun similar to what the Koenigsegg's sports/hyper car is using on their engines.

Main reason is emission control. If there are no emission regulations then the old banger won't be replaced by CRDi.

Oldies are plain & simple, no much electronics and sensors, does not need to operate at higher pressures. At higher pressures components operate at very tight tolerances and are prone to failure. At higher emission controls, you put up many technologies to lower it thus all emission control device is a great enemy of the engine when it comes to maintenance. If they break, they cause chain of reaction up to the point of engine grenades itself. Over time, imperfections of any newer engines are fixed.

IMHO, the old school diesel is oftentimes more economical than the modern diesel because it is simply incapable of pumping fuel any faster due to the low pressure injection pump. So no matter how much I flog my Revo diesel, it can only accelerate as fast, and therefore only consume at a rate of 7km/L at the worst case scenario.

My Santa Fe CRDi on the other hand, has around twice the horsepower and torque as the Revo and to achieve that utilizes a more modern high pressure pump which enables it to pump in fuel at a faster rate as my irresponsible right foot demands more speed out of it. [emoji28] Therefore gas mileage once went as low as 4.6km/L. A route change and a much, MUCH lighter foot later, that was reversed to 6.4km/L. I am still in the process of discovering whether I would be able to replicate the Revo's gas mileage if I drive as lethargically as I do in the Revo...

totally agree. hence, as one poster here already exemplified, newer technologies on minimising overhead in multi injection can be optimized by Mivec, skyactive , diesel VVTis whatever... certainly will improve fuel economy in the long term.

Maybe swapping your revo's engine to your Sta fe's hahaha will do

try a piggyback chip to raise the rail pressure even more. newer models have active hardware with algorithm programmed into it. some claimed it does improves drivability and fuel economy in city driving. but a remap will surely do wonders if done properly to optimize for economy (and may sacrifice performance). performance = fuel and more performance = more fuel ... and larger turbos

The Revo was given to another family member who is in need. Hence the buying of the Santa Fe. I do kind of miss the 7-8km/L city consumption. Do tell, is there any modern CRDi that achieves that as a worst case scenario fuel consumption? [emoji23]

I really do hope the Santa Fe makes up for it in good highway gas mileage. I have been too busy to take it for a proper long distance trip since buying it...

It does have, already! I've installed the Unichip from Speedlab which improved power to 145whp and 266lbft. I have also done the Revive treatment from Central Diesel. While the significant performance improvement is definitely welcome, there was no significant difference in fuel consumption... [emoji853]

They say the RZ4E from isuzu gets 9km/l in the city tho. The hyundai accent has a thrifty crdi..

How about the diesel crv?
