转发一篇关于Toyota 1GD-FTV引擎的文章。现款的HiLux, Fortuner, Prado都是用的这个引擎。
简单的说就是，Toyota的1GD-FTV发动机的air-inlet系统有设计缺陷，会让灰尘通过air filter，干扰MAF(mass air flow) 传感器的数据读取，ECU会根据这个错误的数据让引擎进入limp模式。
Toyota Australia承认有这个问题，但认为这个问题不会损坏引擎，也不会造成危险，所以不会进行召回。
车辆越舒适越复杂，可靠性就会越差，Toyota也不能免俗。
Toyota 1GD-FTV bites the dust
Recently we did a six-vehicle comparison test in the outback of South Australia in Unsealed 4X4, pitting a bunch of current dual-cab utes against one another. During the testing, the HiLux Rugged X test vehicle’s 1GD-FTV dropped into ‘limp mode’ four times due to dust ingress.
It’s so dusty out here, even the dust has dust!
The new-tech 2.8L 1GD-FTV is the engine utilised across the current HiLux, Fortuner and Prado models after Toyota phased out the 3.0L 1KD-FTV, which itself is beginning to turn up many issues relating to injectors causing engine failure.
Specifically for the new-tech 1GD-FTV, Toyota Australia has admitted there is a design flaw in the air-inlet system that allows dust past the air filter, which in turn corrupt the sensor readings within the mass air flow sensor. The ECU then utilises these readings to determine the correct fuel ratios for the engine to run. The corrupted data then prompts the engine to go into limp mode, which is a potentially dangerous outcome in certain situations, say mid-way through overtaking. During our testing, we managed to reset the ECU & limp mode by disconnecting and reconnecting the battery (have you tried turning it off and back on again?)
While Toyota Australia’s spokesperson assured us that any dust making its way past the filter, would be very fine (less than 5-microns in size), they further stated that dust of this size is “not known to cause engine damage.” We’re not entirely sure on that one, but we’ve got a filtration expert on speed dial, so we’ll get back to you on that one.
Toyota Australia further went on to say, “as the vehicle is subject to reduced engine power (‘limp mode’) and can continue to be operated safely, it is not a safety related item that would require a recall,” so don’t expect a letter from Toyota asking you to come in and have the flaw rectified. They have only publicly acknowledged the flaw in the wake of our testing, however there was a dealer bulletin released in March last year, advising of the issue, and the owners should be advised to ‘clean their air filter more often in dusty conditions’, as well as to blow the MAF sensor out with compressed air when completing services.
With all this in mind, a request for a fix has apparently been sent back to Toyota Japan, so hopefully there will be design changes that should eliminate this issue.
After the issues with the 1KD injectors, and now further issues with dust ingress in the 1GD-FTV, it seems that Toyota’s reputation for making indestructible, unbreakable HiLuxes might be starting to waver. Stay tuned, as we’ll get back to you with our dusty expert’s thoughts on the 1GD eating dust as soon as we can get him on the phone!

请教高手，，，1VD-FTV 也有问题吗？

我不是高手，但是我看到过鬼佬吐槽这个问题，turbo blade伤痕累累，鬼佬说是air filter box密封不好，所以改装了一个铁的用螺丝拧紧

参考这篇文章 YOUR TOYOTA HILUX MIGHT HAVE A DUST INGESTING PROBLEM.
Toyota Australia对这个dust getting past the air filter system问题给出的建议是：
Owners are also being made aware of the issue and being advised to clean the filter more often.
“It’s important that the air filter is checked more regularly in extremely dusty conditions … it’s an easy fix to have dust blown out [to clean the sensor].”
It has also been found that an air snorkel, such as fitted to the Rugged X we tested, can exacerbate the problem. Toyota says that issue can be reduced by turning the intake rearward, a recommendation it makes in the Rugged X owner’s manual.

Toyota Australia关于dust getting past the air filter system的问题解释:
a. "In general, this type of very fine dust is not known to cause engine damage".
b. "it can be managed by more frequent filter changes and some compressed air onto the MAF sensor every now and then".
参考这篇文章HERE’S WHAT A FILTRATION EXPERT THINKS ABOUT TOYOTA’S DUST PROBLEM
里面有不同的看法。
简单的摘抄一下：
a. "if those dust particles are making their way into turbochargers and internal engine components, they will be definitely contributing an engine wearing out faster".
b. "constantly changing the filter isn’t going help if the filter system is ineffective. There is a chance that the filter housing isn’t sealing correctly, so dusty air is bypassing the filter". 而且，" if the filter is the problem, changing it more often will let more dust through!"

在进气用不是太黏的胶布裹一圈就行了 他这个1gd确实问题太多了

1VD-FTV总的来说比较可靠。
但有一定比例的1VD-FTV会烧机油，这些有问题的1VD-FTV会每4000-5000公里消耗1升机油。
这个问题其实存在很长时间了。
