New 3.5t tipper

[lux]

I’ll freely admit the torque/horsepower thing is a little beyond me, I get it but not completely.
 
But I’ve driven 4wd pickups starting with the non turbo hilux in 98 to now.
The improvement in power is amazing, towing a 3.5 tonne load was nerve racking back then, up and down the box, dreading hills on the motorway, an embarrassment tbh, these days a pice of cake.

Yeah they’ve come a long way.

My first hilux was a 3 litre surf. Lovely car. Way underpowered by my current ones figures though. Would struggle towing the same weights.
I mapped the invincible to 230 ish bhp. It’s been a superb vehicle.

Had defenders etc etc. Non of the vehicles are perfect. The pickups are the best compromise in 4x4 terms for me. Hilux just happens to be the flavour I like best but they are all decent these days. All have their faults and good points.

My transit is only a 125bhp 2.4. As a tow vehicle on the road it’s probably my favourite. It’s geared well and the big wide long wheel base and extra weight really irons out the pitch/yaw effect of a trailer on the tow bar especially down bumpy back roads.

i bought a 2011, 2.4 TDCi Transit double cab tipper 12 months ago,  i was aware that in 2012 the MK7 went from having the 2.4 to the newer type 2.2 which could potentially be troublesome and i'd seen a few go bang in Transits and Rangers.  I got lucky as i had some spare dollar and simply phoned up a local independent Transit specialist and he had it for sale,  he'd been servicing and MOT'ing it for 6 years for a customer.  It was very clean and tidy and i 'lucked out' as it was exactly what i was after spec wise.  115PS, fairly low ratio rear diff,  leccy windows, hill start assist etc. Spent a few quid on it recently having the inlet manifold removed and cleaned out, egr blanked off etc. I have a very fussy mechanic who looks after it for me and that i like.   It may see me out despite being now 11 years old as i'll most likely hang onto it 'till the end'.

Horse power is a misleading figure in working vehicle terms.

A 1.8 golf will have more bhp than the Ford Ranger.

An 18 t lorry has the same sort of horse power as a sporty estate car

Not even worth looking at horse power figures on vans. Down to torque and how it’s geared.

Modern engines are more efficient and burn cleaner with less pollution but they use more fuel to do it.

Anyone buying a new tipper just needs to buy the best they can realistically afford. The least abused and most looked after

My mk7 2.4 transit has been superb. Hard to find a good clean sensible mileage one now though.

Worst thing I’ve driven of late is the 1.9 Isuzu grafter. What a miserable van that is in every respect.




 

Hi 

Can you explain how an engine can be more efficient but use more fuel? I was under the impression an engine being more efficient ment it used less fuel?

Thanks

It’s more efficient from an emissions standpoint point which is all the gov care about, the fact it uses more fuel and add blue to do this they don’t care about, as they make more money due to the taxes on those products

Some Exhaust gasses are passed back through the engine and more fuel is used running hotter to give cleaner overall emissions.

Actually that stupid invention warms an engine little faster after reaching a minimum temp, but the combustion process runs cooler. 

[lux]

exhaust circulation is used to reduce the oxygen in the cylinder when there is too much for the cleanest burn ratio.
When there is little fuel being injected, the air/fuel ratio changes and too much oxygen in the burn creates more NOx - NOx is one of the main gasses that the emissions legislations are trying to combat.

A bigger engine which isnt working very hard will last much longer, but it produces more NOx, etc. Hence manufacturers turning to smaller engines which are working harder, they produce a hotter, cleaner burn - naturally this uses more fuel, extra fuel is also used to heat the engine up quicker from cold as its most efficient at working temperature and more fuel used again to clean the dpf during regeneration.
Result is a thirsty vehicle which produces less emissions [emoji1474]

Basically this.

 

When the diesel is producing little power there is a lot of excess oxygen in the cylinder  but because little fuel is being used the temperature and pressure remains low, so little oxygen combines with the nitrogen. As you produce more power by injecting more fuel per cylinder the oxygen still remains in excess but now the temperature and pressure increase such that nitrogen and oxygen react to produce  nitrogen oxides, this is the stage at which exhaust gas is reintroduced as it contains less oxygen, more carbon dioxide and the same amount of nitrogen. This lowers the temperature in the cylinder and the oxygen concentration.  At full power whilst the temperature and pressure are maximised there is little oxygen left to react with nitrogen. So quite a feat to add just the right amount of EGR according to engine parameters at one moment

 

NOx are implicated with combining with chemicals in the atmosphere (mostly sulfates I think) to produce particulates.

 

Adblue in combination with some catalysts in the exhaust introduces urea CO(NH2)2 to combine with these NOx and convert them to plain N2 and more water and carbon dioxide.

 

I've not experienced DPFs and regeneration as all my diesels are older than 10 years, most 40 years old plus but it strikes me EGR will increase soot production and hence DPF blocking and then the regeneration will need added fuel (in the wrong place in the case of the Dmax).

 

If Adblue works then why does an engine need EGR? If DPFs work and reduce particulates why demonise diesels that have them?

Joking aside, how is a 2l lump going to compare with a 3.2 15 years down the line, doing exactly the same work?

 

You’re a switched on bloke, I know it won’t be your problem.

 

But it will be someone’s problem.

I've got a new 2.0 ranger and all I can say is thank god its only on a 3 year lease!  

It's a car engine, has no place in a truck, there's just not enough mass in the engine to my mind. 

My Dad has 3.2,  I know which one will be in the scrap yard first.... 

I'm not looking forward to deciding on its replacement,  but I think it's going to be a discovery 4 (possibly 5, depending on how the market looks at the time) and just accept that it'll need a lot more spending on maintenance.  At least I'll be driving something I like, and it'll be 4 times as good a tow vehicle!

i have a 2018 3.2 wildtrak, been remapped since 2k miles and i'm now just over 40k. not had 1 single engine issue

silicone hoses, dpf delete, adblue delete, egr blanked off, exhaust. notice a difference with how smooth it is compared to stock. 

i did try the 2l for a couple of weeks and didn't really like the 10 speed as much as i thought i would, it has to use to gears to try and make up for the lack of displacement, so when towing its constantly hunting for the best gear

 

the 2023 ranger with the v6 should clear up the 2l issue!
