4A-GE / automatic transmission, gasoline consumption in winter - Toyota Sprinter, 1.6 liter, 1994
Hello everyone, we have a 94-year-old sprinter silver top on an automatic machine. Gasoline consumption on a mixed driving cycle is about 15-20 liters / 100km
, an exhaust without a catalyst is installed, warming up is -10C at engine temperature, consumed gasoline is 92/96.
is it ok?
another question
is what can change:
with the transition to 98 gasoline, it is required by the manufacturer
to clean the fuel system (throttle, force, fuel filter)
with cleaning the flow meter.
whether to do everything in a complex ... or how.
in short HELP, I want to talk constructively with people who understand these motors.
thanks

To be honest, consumption per 100 km / h, as many are used to measuring, is nothing. The figure is interesting for taxi drivers, perhaps.
You need to start from the mode of operation.
I don’t know for sure, let’s say a serviceable 4A-GE eats 0.9 l / h in XX mode. In warm-up mode - three times more. Accordingly, if the runs are small, the consumption will consist of half or even more warm-ups.

will be less under load
>with fuel system cleaning
consumption, dynamics… depends on the situation
> with the cleaning of the flow meter
, the adequacy of measurements will increase, the composition of the mixture, the flow rate will improve a little, the dynamics ... and what about the blade? (flattype) for some reason I thought that GE is on the map, but only 4A-GZE on the shoulder blade
It should be easier - ask a person to drive from behind and see if there is soot in the back, if there is one, at what speeds, modes. Then analyze and think.
For you can clean and change consumables until you turn blue. But we must not forget that this is EFI - and here sensors and computers mainly rule - and they need to create all the conditions for normal operation.
pouring into 4a-ge is recommended by the manufacturer brand of gasoline Premium, i.e. 95, from which everyone took that they pour 98 into black, the compression ratio is 11, and ai98 starts with a compression ratio above 12
Cleaning the bypass channel in the MAF will deplete the mixture below, and cleaning the BDZ will raise the XX.
Here it is in more detail please, and so everything is clear.
and also how to find out what condition the motor is in, without disassembling it much, since 92 was constantly pouring into it before me.
Would a compression test fix this issue?
The possibility of using low-octane gasolines depends on the degree of compression, angles, phases.
It seems to me that 10.5 (ST) and even more so 11 (BT) definitely excludes 92 gasoline (it is characterized by 9.5 or something).
IMHO, if you do not tumble, then you can go to 92, the computer must adjust to gasoline.
The catastrophe for the engine is not gasoline itself, but the devastating effects of detonation that it can cause.
When you clean the entire intake, I recommend then resetting the ECU (remove the battery terminal for 5 minutes), because the operating parameters will change. Cleaning the bypass channel in the MAF will deplete the mixture below, and cleaning the BDZ will raise the XX.
nice to read!
that is, 92/95 is not a disaster for the motor?
I want to clean the fuel one, because I bought it in the village
and I have a shovel, well, clean it like that))

understood. well, the method is normal) the candles were unscrewed and chik chik chik)
depends on the instrument, the battery, the method of measurement, I think you should not count on something around 12.5-13.5 Look at the spread over the cylinders, this is the main thing.
in MAF there is a bypass valve (I think this also applies to 4A), which is regulated by pain. a fixed amount of air passes through it, which is significant at low speeds and especially at idle. If it is opened slightly, the damper will open less, and, accordingly, less fuel will flow. Over time, it becomes covered with a small layer of dust, which will affect the tuning.
here we talked a lot and for a long time about MAF

Cleaning the air intake, similarly, will allow more air to pass through (you still need to clean the electronic regulator on the bypass channel). This means that the RPM's will go up.
In general, my advice is to clean it, if after cleaning the problems appear, they are easily eliminated, and in any case it will only get better.
Yes, the compression measurement will say quite a lot, especially regarding the consequences of 92, I think this is the most correct idea.
understood. well, the method is ordinary)) the candles were unscrewed and chik chik chik))
Friend, Lei is only 98 benz, you will see the difference)))) Damn, when 102 benz will be imported into Russia)))) Oh, he left the topic, you will notice how the valves stop ringing!
in Japan, who does not know, there is no 92nd gasoline at all! they have the most minimal analogue of our 95th, but the cars adjust the ignition and under our 92, the engine does not work in optimal conditions. the consequences of using non-recommended gasoline are as follows: the design power of the engine is slightly reduced, and because of this, there is an inconsistency between the operation of the internal combustion engine and the gearbox, the latter begins to "stupid" (yes, this happens precisely because of this, with rare exceptions). I pour what is recommended by the manufacturer and I advise everyone to do the same!
consumption for 160 moose on a machine with normal warm-ups! I have 85 on a stick in winter 12-13 without any warm-ups, so don't worry)
Yes, normal consumption, in the summer corolla bz-touring 13-15 ate on a sotochka, track 9. automatic. Karina with a friend on a stick 12-13 in the summer. It's all in quiet mode. so don't worry, and most importantly, don't listen to what he has to eat 8 liters))))
Probably no longer relevant, but still for those who come in - it may come in handy for someone ...
Kaldina 3SGE 3Gen 96 year Manual transmission 4WD summer 10 lt per hundred km in the city (both sick and no - no imbedded) track 8 lt at 110-120 km per hour 3100-3200 thousand rpm, winter - a city without warming up at night 12-14 depending on the temperature at -30 14 lt, at -20/25 12 lt, a lot depends on the state of the automatic transmission of the internal combustion engine and the mileage per day, if you drive a little mileage and more warm at startup, then the consumption for winter is quite normal, all the same, the car is old and the total fatigue of the units in it working together is already high, this is the mass air flow sensor and candles and the distributor and compression, well, the main culprit of high consumption in the winter, and in general the destruction of the dynamics of this magnificent motor, this is an automatic transmission!
And finally - DO NOT PUT IN ANY EVENT INTO ENGINES WITH THE GE AI-92 ATTACHMENT, 4AGE has a compression ratio of 11, it needs 98-100 benz, 3SGE 3Gen 10 migimmum AI-95!
Do not kill these wonderful motors with 92 RUSSIAN gasoline, which is rarely enough for 92 octane at any gas station.
I don’t know how it is on silver, but on black in winter on a machine on a sprinter 12-13, 15, well, this is a direct maximum if I move in dashes (started, turned off, warmed up) I drive gas to the floor every day, and on a beezer even in winter even in summer 10 liters is stable and I couldn’t squeeze more than I didn’t try, well, 11 is a direct ceiling! (and no one believes the main thing is that this is possible)))) it seems that it’s worth warming up, at idle I noticed there is as much as you could ride during this time, but nah do you heat it up?
