Macmilla:

You know that guy that races every car that es him on the highway? That is me.
I once raced a v8 Prado jeep with my tiny i4 engine. The man new I was chasing him and he made me look like a fool severally. I later ed him technically. #in Lai Mohammed's voice.

lol, then guy go for more power, not even just v6 but check the horse power, for person like you the difference in petrol is not even up to 2mpg and again that v6 in solara 2nd gen is the same engine in lexus RX330, it will do a great job for you.

Macmilla:

The more u guys argue, the more I see reasons to stay away from i4 and embrace v6. The bold line just describes me. I just had to back off a deal I had for a 2nd gen i4 solara. Going for v6 of same ride instead.

yes v6 is better, you only feel the difference in economy much around town and city traffic. But again there are ppl that is very obssesive of fuel economy like me, hybrid is in my mind, that extra liters in fill up just make me unhappy because i dont care about speed or power, all i care about is smooth economical car.

Siena:


True, to a certain extent. To be clear here, cruising is the art of accelerating up to a decent speed, then backing off slightly, allowing the engine to run on a part-open throttle. This is where any engine is most economical - providing the engine produces enough torque to maintain useful vehicle motion.

However, with an under-powered I4 engine, it is harder to maintain that sweet spot (approximately 2800-3200 rpm @ 70 mph). A naturally-aspirated I4 up to 2.0 litres with a modern 16V cylinder head is peaky, meaning it makes good power, but further up the rev range. This means the gearbox will be geared lower to make use of the high-revving characteristics inherent in naturally-aspirated multivalve engines.

Between 2800 and 3200 rpm, such an engine will not make bags of torque to sustain a constant road speed, without pushing the pedal harder every now and again. A turbocharged 4 will be happy here. So will a larger-capacity V6, boosted or naturally-aspirated. I have done long-distance trip, mostly driving on the Continent, with 4 engers and luggage. I have found 4 cylinder engines to be thirstier on these trips. The smallest engined-car I drove from Central London through Calais, ending up in Brittany, Northern was a 2003 Renault Clio 1.4 16V manual. The car was 10 months old then, it averaged 44 mpg over 633 miles. My 2005 Audi A8 Quattro 4.2 V8 with a 6-speed Tiptronic transmission did the same trip, and averaged 32.7 mpg over 629 miles. It was much easier to maintain the sweet spot with the bigger car, and the engine was more relaxed.

You are correct but there is something I want you to know what I mean by sweet spot. I mean very very flexible speed even below 60mph when climbing hill, just making sure the the engine is not working hard as it should. That is why I said v6 is best for power and speed minded individual because such person will end up working l4 harder thereby Making fuel economy even worse than v6 because v6 wouldn't need to be worked hard but if a person is economy minded like high miler like me, he will be able to speed to high speed at appropriate time like down hills and able to keep in engine always in best optimum operations even if it takes dropping speed to 40mph up hills. this also mean cruise control is not good for a good high miler, I said good high miler.

V6 are generally bound to consume more fuel than l4. the fuel effiennt difference becomes reduce significantly if you usual travel long distance and also like high speed and racing that is when it is hard to notice. but v6 becomes pain in around town, in traffic and if you are conservative driver. l4 efficeient is still noticeable in long journey if you allow the rev to remain in sweet spot and avoid chasing cars.

Siena:
It's a common misconception that a V6 engine will use more fuel than an I4.

Fuel consumption is determined by:

Engine capacity.
Internal friction.
Emission level.
Vehicle weight.
Transmission type.

The most determining factor is the engine capacity. This is is the actual swept volume of the engine, the cylinder bores the pistons operate in. It stands to reason the larger the capacity, the more fuel is required to feed it. Sometimes though, the engine is designed to run lean (lean-burn technology) and so a 2.2L engine MAY use LESS fuel than a 1.8L version with standard fuel injection. Design is key.

Internal friction will also affect fuel mileage. This is where there is more resistance to rotation and piston movement. More resistance will require x amount more of fuel.

Emission levels are becoming increasingly stringent. We're currently on Euro 5, though 6 is just being introduced. The lower the emission level number, the more fuel the engine will use.

The myths that a V6 engine will use more fuel than an I4 are just that - myths. The main assumption here is that a V6 engine has a larger capacity than an I4. This is not always the case.

A Mazda 1.8 comes as a V6 in the '97 gMazda 323F. It WILL use LESS fuel than a 2.2 I4 in the '98 Toyota Camry. Euro 2 Vs Euro 2.
A Porsche 3.0 comes as an I4 in the '91 Porsche 944 S2. It WILL use MORE fuel than a 3.2 V6 FSI in a 2006 Audi A4. Euro 3 Vs Euro 5.
A Jeep 4.0 comes as an I6 in the '99 Wrangler. It WILL use MORE fuel than a 3.7 V8 40V in a 1999 Audi A8 Quattro. Euro 3 Vs Euro 3.

The above are just 3 out of millions of variables. I will cite another example to do with weight.

A '91 E34 BMW 518i (1.8L I4) WILL use MORE fuel than a '91 E34 BMW 520i (2.0 I6). Both Euro 3, but the smaller 1.8 4 cylinder in a relatively heavy car will be working harder, and require MORE fuel as a result. The bigger 2.0 6 cylinder will have an easier time, and require LESS fuel. This is one of the reasons BMW dropped the 1.8 engine for the 1992 model year in the E39. For those who allow their mechanics to yank out their engines in favour of a smaller version, take note!

Transmission type will also determine how much 2 similar engines will use fuel.

I disagree with this parmutation. Euro classification is based on CO2 emission and CO2 emission is not proportional to mpg especially when comparing old engine with newer engine with a lot of improved technology to reduce emission. in nutshell that two engine has different; Euro 4 can be more efficient than Euro 5 but the clasiffication show Euro 5 has lower co2 emission. And lets not forget that in latest engine devolopment, there a lot of l4 turbo that has power of v6 with efficiency of l4 likewise v6 and v8. and most importantly effient also depend on engine manufacturer.

Thanks, it helps a lot.

I used my logical reasoning to assume somethings but later got it when pros came with details. If you read all comments you would have seen it.

Your comment has added to what have been said especially with regards to P, V, I and R with their relationships. The solution is bolded and the basis to the question i first asked.

Basically, the question was this way;
1. I have an inverter 1.2kva 12v 20A charger with one 12v 200ah battery
2. My friend has 2.4kva 24v 20A charger with two 12v 200ah battery in series.

I initially thought my friend's system would take twice as long as mine to fully charge (assuming resistance is the same and state of charge of batteries are all same).

After all that was said, my current understanding is that the two systems above will have approximately same charging time considering the assumptions made. Hope that is correct.

That is correct but where people are wrong is in of battery runtime and variables used in the calculations. if the same appliance is used in both let say 30w light, 2* 200AH will last twice th 200AH in ideal condition.

adanny01:


Initially, i thought otherwise that a 20amp charger for example will deliver the same power in any voltage system and would naturally take longer to charge when battery bank is increased. I have realised that thats not the only case since when voltage increases, power delivery increases proportionally. I arrived at a conclusion in this post below.



I got this reply from Chris which got me a little confused and sought to get some more explanations leading to the exchanges.



Thank you for your contribution. I now understand why Mercury 1.2kva 12v and 2.4kva 24v inverter have the same charging current of 20A but same charging time even with the 24v having twice the battery bank.

All this calculations of charging capacity by p=iv is totally wrong brother. charging capacity has nothing to do with voltage, 12v, 24v etc, but has a lot to do with AH of the battery being charged. As AH of battery increases so do the resist to follow of charger current. this means charging 100AH battery is faster than charging 200AH Charge ( coulumb) Q = current Amp * time. that is Q=Ampare* time in seconds. this means is only current rating of charger determine how fast it charges independent of voltage but also heavily depends on opposition to follow of this current per time, that opposition is called resistance of the battery being charged if the Amp of charger is the same. Resistance of battery R=V/I of the battery. So in Ideal world a battery connected in series to increase voltage while AH remain the same will get charged twice faster than battery connected in parallel to increase the AH while voltage remaining the same because the resistance will increase significantly too but where the real world charging scenario come to play is that since this solemnly depends on resistance if the Amp of charger is the same, there are a lot of factors that determines resistance, not only volt/AH of batteries. The wires size, the cell (there is no way the two battery are the same), the electrolyte, temperature of the batteries and of that environment etc. Hope this help a beat.

power watts, is the laod the said system can carry.

@adanny01, I just want to say something in regards to charging time in relation to battery amperage and voltage.

All this calcutiobs of charging capacity by p=iv is totally wrong brother. charging capacity has nothing to do with voltage, 12v, 24v etc, but has a lot to do with AH of the battery being charged. As AH of battery increases so do the resist to follow of charger current. this means charging 100AH battery is faster thsn charging 200AH Charge ( coulumb) = current * time. that is C=Ampare* time in seconds. this means is only current rating of charger dertemine how fast it charges independet of voltage tage.

what the price of the mercury deep cycle and Tubullar?

Thanks and wish you all profit and no loss.

The price is $12 in ebay.

Wow, this is real eye opener. Middle men business are in trouble. This scammers are just busy destroying the honest man's means to eat. Things are really getting worse everyday. Nawao. Thank God he didn't succeed.

The buyer don't know the middle men (scammer) and does not know the real dealer? Did the buyer deposit any money to him ( middle men)? if yes, what is happening between the two now?

Rav 4, CRV, Camry, Accord, C class, etc with 4 plugs not 6 plugs are within 11 /12L/100km.

Yaris 6.5L/100km
corolla 7L/100km

kaeforum:


I don't know what you mean, could you clarify?

What do you understand by bio- diesel? do you know that diesel engine do run smoothly with vegetables oil ( cooking oil, even the one that has been used for food already). how about that compare with your so called adulterated?

naijadeyhia:



Dude i own 3 rides that are point blank reliable anyday anytime and they are all 2005. A lincoln navi, a dodge caravan and a bmw x5, my wife drives the dodge. So you see, i am a sucker for reliability. 2 american brands and 1 german. Nothing beats a rugged vehicle. Have never driven a lemon all my life. Have gone from Benz to volvo to american and german but never japanese.

Sir, it seems like you have all this car but very limited in knowledge of them. American car (dodge, Chevrolet, Pontiac, etc are the same GM cars) is the most unreliable cars around, doubt? go to car complaints commission and car survey and find out. There is reasons why American don't buy them like the used to buy imported cars and are always complaining, regretting every time in owners review sections.
When it comes to German, in Nigeria mercedes yes, BMW and Opel no. why? Bmw has very complex engines that whenever it start developing fault in Nigeria, is good as dead because of limited engineers in Nigeria that can attend to his needs without causing more damage.
When it comes to Kia, there is reason they offer 7 years warranty/150,000km while others are just 5 or 3 years/100,000km. Go to consumer report or reliability survey and find out the most car with reliabilities issues because kia and Hyundai is something special now. Internet has make world very small place and informations readily available not i think . #get to know what you buy.

In my opinion, being new or presenting a customer testimony doesn't count much. After all, there must be first person to patronize new car dealer and there will always be first person that a marketer will use to build his/her reputation. If it is to go this way ppl always think now, it means neither new dealer nor a dealer without a testimony will do sales in NL.
When it comes to KingAuto, his stories doesn't add up. if u mention he is newly ed, he will tell u he has been in existance since 2009. since he said so, he has to provide evidence and deals done. The truth is that there is no sincerity in any of his comments.

nobeku:
I don't think that's even de issue..you can find european cars in America and de owner might just wanna sell his/her car...what I am saying is for dis Kings dude to step right up to de hot seat and defend himself BEYOUND REASONABLE DOUBT!!!!

How can you find European car in America especially if thesame car is sold there with better engine and spec? do you know that it is very very hard to find Canada market car in USA. If doubt check out Acura EL And CSX that is meant for canada market only and see. But anyway. the only way for you to confirm is give him deposit. lolz.
