same engine displacement diff HP

**jtbjr** · March 7th, 2011 08:20 PM

hi sirs,

just curious, why is that a 2.5d4-d engine has much lesser HP
than a 2.5montero and almost the same power as 1.5hyundai crdi engine, in the same way, a 1.5vvti engine as the same HP as the 1.4 hyundai accent engine?
why is this like this? anybody knows the logic of these why toyota's engine are made to have less power compared to its competition? cost savings??effeciency?? thanks in advance

It means mas genius ang ECU's ng hyundai compared sa toyota at mitsu.
Marami na kasi factors para maitaas ang power ng auto. ECU, Turbo, number ng camshafts.

There are some factors like body weight, gear ratio and gear final ratio that you should consider.

One reason is the way the engines are tuned by the manufacturer, particular to the model being offered. Not necessarily because of technology but rather, practicality for the application.

It may be necessary to increase the output of an engine for use on utility vehicles (like pick-ups) by installing an intercooler, whereby you can increase the volume of cool air to be delivered to the engine, hence greater output. Stretching an engines power output may shorten it's useful life though. The D4D's turbocharging set-up is basic(without intercooler) while for the Mitsu is Intercooled.

The d4d's output of 100hp on the innova is just okay, if I may say so. The Montero on the other hand is a bit heavier as compared to the Innova so more power is ideal and so goes with the other brands.

And then another reason is in the Technology itself (Hyundai's). Developing theirs based on the more advanced European technology.

technology and the components INSIDE the engines.

bakit kanyo?

ang civic SiR at ang regular civic ay may parehong 1.6 engine. tig apat din cylinders nila. pero anlayo ng power ng sir sa vti civic.

the secret is in the internal engine design... the sir has more cams, a better air intake, better computer. yung ibang kotse ganun din... minsan parehong engine nga pero magkaiba ang power (4d56 turbo and non turbo).

TAMA! example lang din, I once saw sa TV yung explanation ng technician ng F1 mclaren team regarding sa piston ng merc cars and F1 cars nila. Malayo yung design ng head ng piston at sobrang nipis/gaan pero good for 2 weeks worth of racing nga lang whereas yung sa prodcution car ay designed naman for longevity. That is why for a specific purpose/car, may specific design din ng engine. Kung makakatipid ka, mas ok diba.

It all depends on the requirements.

The Innova D4D doesn't make a lot of power, but it's cheap to build and economical (as good as the Isuzu 4JA1 or better, actually). A more powerful motor would drive the price of the Innova up without adding anything that the buyers need.

SUV buyers expect power, which is why the Fortuner gets the more powerful 3.0.

HARI also offers models with different engine trims. The base Grand Starex has a weaker non-CRDI 2.5, whereas the top-of-the-line model gets a 170 hp 2.5 CRDI.

fortuner comes with the 2.5 crdi engines,just like the innova, on 4x2 models, 3liter engine on 4x4.
toyota 2kd engine as good as the isuzu 4ja1 engine or even better? when it comes to acceleration and top speed, yes, but durability? I highly doubt it. Wala pa napapatunayan sa diesel engine ang toyota, kahit nga un sister company nila na hino, sirain ang makina

Masyadong malaki ang generation gap ng Common rail at mechanical injection pump para paghambingin sila. Parang sugar ray robinson vs manny pacquiao.Dapat yung counterpart ng bawat isa ang paglabanin gaya halimbawa ng 2L vs 4d56 vs 4ja1.

Hindi sirain diesel ng Toyota pre IMO. The 2Lt and 3Lt diesel non-crdi of their hilux is proof of that. Matibay yun, on par with MMC or Isuzu. Don't generalize agad.

Hanggang ngayon nga hilux pa preferred battle car sa Africa eh. Even Top Gear is impressed with its durability and performance. We have in our office a 2003 hilux 2L engine 2.4. 289K odo, no overhaul pa rin. Same with a 2.8 hilux 4x4, 250K odo, no overhaul pa rin. Pang-business pa yan at laging kargado ng kung ano-anong produkto sa grocery. Matibay siya based on my experience. Mas matulin pa nga 2L engine kesa 4d56 eh (it was able to reach 160km/h). Kahit na 2.4 lang yun at 2.5 ang 4d56.
