柴油机加汽油就完蛋了,柴油机压燃式,汽油燃点低,没压到低就炸了,柴油机就完蛋了

外行了吧,柴油机压缩的时候里面没有燃料,所以不存在没压倒底就炸了的问题。柴油
机是压缩纯空气,压到底以后才喷燃料,所以燃料适用范围很广,从煤油到地沟油(所
谓的生物柴油其实就是地沟油)都能烧,加了一点点汽油混合一下损害不大,把油箱里
的汽油抽出来重新加柴油就差不多了,当然要是里面加多了汽油那是另一回事了,赶紧
拖车去清洗吧。

A***n 发帖数: 8859 | 10 求真相
不过这个两万psi injection pressure看来,似乎是先压空气再喷油多些。
In the real world if you are traveling along at 2300 rpm in 5th gear at
about 68 miles per hour and getting 45 miles to an US gal. your injection
pressure is about 5600 psi.
If for some reason you floored the go pedal at this same speed and your
torque output at the crank goes from 44 ft lbs to 177 ft lbs and your fuel
use increases proportionally you’re injection pressure would jump to 21000
psi.

A***n 发帖数: 8859 | 12 我表达不好,我意思是倾向支持你的说法。
因为只有那样才好控制喷油时机和喷油量,不然很难控制点燃时机
您真是內行,解我一惑。

油路,cost大概是300刀。
在TDI论坛上曾经看到一个Touareg owner加错了油,为了不给别人惹麻烦,还是发动起
来十几秒钟把车pull over让出加油口。结果dealer quote了$8000。

不过你要是真的加了汽油到柴油机里还是不要发动,立即清洗比较稳妥。下面这篇文章
讲得很详细:
What happens if you inadvertently fill your diesel car with gasoline?
Whether you're new to diesel ownership, or might have both diesel and
gasoline powered vehicles in your own personal fleet, it can be oh-so-easy
to accidentally mis-fuel your diesel tank with gasoline. Filling your fuel
tank is such an ordinary and mundane task, that just a moment's inattention
can cause you to grab the wrong nozzle and pump away. Bad enough if you
realize the mistake right away and can get the car towed to a shop to have
the tank drained (an awfully expensive nuisance), but what if you don't even
realize the mistake and end up driving away with a tank full of gasoline?
Chances are you won't get very far (maybe just a mile or so until the diesel
in the fuel line gives way to the fresh batch of gasoline on the way from
the tank) and the engine starts to run "funny."
Of course, it all depends on how much diesel remained in the tank before the
gasoline was added, and how new and sophisticated the diesel engine is. In
a 2007 or newer clean diesel engine, any amount of gasoline will probably
damage the sensitive emissions control components (DPF, OxyCat and SCR) and
system. In older engines with much less sophisticated and "touchy" emissions
systems, a lightly diluted (say 90 percent diesel/10 percent gasoline) mix
would probably pass through with little or no detriment. It might simply
cause reduced engine power, perhaps a bit more noise, and possibly a sharp
warning from the emissions sensors that detect something other than pure
diesel exhaust. It's high concentrations of gasoline that spell real trouble
. Whether a modern clean CRD diesel or an old indirect injection unit,
burning straight gasoline or highly diluted diesel fuel will almost
certainly result in catastrophic damage to the mighty diesel engine.
Diesel Fuel and Compression Ignition
Diesel engines rely on compression ignition and run at much higher
compression ratios and cylinder pressures than their gasoline counterparts.
It is this higher compression ratio that creates the necessary heat to auto-
ignite and burn low volatility oil-type fuels such as diesel fuel and
biodiesel.
Gasoline and Spark Ignition
Gasoline engines are built much less stoutly than diesels and generate far
lower combustion chamber compression ratios. Because these engines don't
build sufficient pressure and heat to ignite dense oil-type fuels, they rely
on timed electric spark ignition to initiate gasoline's highly volatile
burn sequence.
So What Does Gasoline do to a Diesel Engine?
The problem is multi-faceted. It is a function of the completely different
burn characteristics of the fuels (volatile and explosive gasoline versus
high flash point diesel fuel), and the peculiarities of engine design in
regards to how fuel is ignited (spark ignition versus compression ignition).
Gasoline is formulated to resist auto-ignition in a spark engine (see
octane), so this fuel introduced into a diesel engine either won't ignite or
will (much more likely) ignite at the wrong time causing severe detonation.
Though diesel engine reciprocating components (pistons, wrist pins and
connecting rods) are built to withstand enormous explosive force, the shock
wave effects of uncontrolled detonation can easily destroy them.
In addition to the specific burn characteristics that diesel fuel and
biodiesel afford to compression ignition diesel engines, the fuel itself
acts as a lubricant for the fuel pump and delivery system as well as the
valve train (recall that diesel fuel is actually a very light oil). Running
thin, low viscosity gasoline through a diesel fuel system would starve it
for lubrication and cause those sensitive components to rub together (metal-
to-metal) eventually destroying them.
But What About the Opposite: Putting Diesel Fuel in a Gasoline Engine?
Fortunately, this one is almost impossible (notice we said almost), since
the filler nozzles on diesel fuel dispensers are larger than those on
gasoline pumps. The typical slow-fill diesel pump nozzle is 15/16" (24 cm)--
fast-fill truck nozzles are even larger, well over 1-inch (25 cm), while the
nozzle for a gasoline pump is about 13/16" (21 cm). Simply put, a large
diesel spout won't fit in a narrow gasoline filler neck, while a smaller
diameter gasoline snout will slip right in a diesel tank opening.
But if you do manage to get diesel fuel in your gasoline tank, (and this
also is dilution dependent) the engine will probably not even start--and if
it does, it'll run terribly and probably smoke like a chimney. Engine damage
will probably be minimal to none, but a thorough (and expensive) fuel
system flush will certainly be in order.

A***n 发帖数: 8859 | 15 合共300刀还可以接受
不过我会原地买个大油箱和吸管先吸空油箱可能更稳妥些,防止进一步抗散
fuel filter有些车很容易拆,要是拆油管放油更好些
