Truck engines

What is the engine capacity (cc)of usual trucks in UK?How many cylinders do they have??

[KebabMeister]

I'm not entirely sure but I think they're mostly between 6 and 10 cylinders.  Engine capacity is anything between 5 and 12 litres.

I am assuming by truck, you mean something with a gross weight over 17.5 tonnes. A truck usually has 6 cylinders in line, except for some Scanias and Mercedes which have V8's. My 8 wheel tipper has a 6 cylinder in line 12.6 litre engine (thats 2100 cc/cylinder). I think the biggest 'normal' engine at the moment are on the Volvo FH and Scania 5 series, both of which have a 16 litre option. However, more important is the computer(nowadays) and fuel pump settings, because these are what give you your horsepower rating. Lets go back to my engine. The basic 12.6litre DAF engine is used in all 85's and 95's, but the available hp varies from 300 to 520. Mine is a 340hp. It all depends on the fuel pump etc. If you want a few more facts, the engine sump is 27 litres and most engines will do about 8 mpg (if you are lucky!!). Tickover is about 550 rpm with red line at 2800 rpm. Max effieciency (marked by a nice green band on the rev counter) is 1000 - 1600 rpm.

Ah of course... didn't Volvo have the F6, F7, F8, F10, F12 & F16 models?  I think the number denoted what litre they were.

Whew....Thanx sddsddean and kebabmeister.Its more than what I wanted!!!

cummins 10 litre, anywhere between 340 bhp and 420 bhp simply by a good 10 minutes with a laptop. well over 8 and approaching 9 mpg in most applications. although the latest man common rail diesel is rumoured to be better on fuel, the long term reliability is an issue though. man-erf wont admit that but the dealer network know better....

Long term reliability could be an issue with many engines Paul . I was talking to the mechanics at my local dealer, 'cos I thought my new trucks engine was much noisier than the old one (they are both basically the same 12.6 litre engine). Apparently, to meet all the emissions limits required to meet the Euro 3 spec, the fuel pump is running at 5 times the pressure it was designed for!, and thats what makes it noisier. Thats a cheery thought when you are bombing down the motorway!

its more of a mechanical issue with the man engine, the out going engine had a good record until recently, with some quite startling failures on low mileage engines under warranty. in five years i have only stripped one cummins ism down as far as the crankshaft, that one was driven off a landfill and for a further mile after having the sump holed and therefore losing all its oil.

[sddsddean]

I know the MAN TG-A has had some mechanical problems since it came out about 4 years ago. My brother in law drives an artic all over the country and he has lost count of the number he has seen by the side of the road. Nearly everytime the prop shaft has parted company with the back of the gearbox. Very messy!!

8 -9 mpg, no wonder the atmosphere is getting knackered. Get it all back on the railways.

interesting... the tga and the erf ect are the same truck except you can get the cummins engine in the ect. gearbox problems are isolated to it jumping out of gear usually 3rd and 7th.we see major failures when drivers get round the max 56mph governor. again the cummins allows us to interrogate the control module and we find it shows an engine overspeed. the way they cheat the limiter is quite brutal, hence the box failures your brother sees. i wont tell you how they do it as too many people know as it is!
