Just a quick query if anyone can answer. The DCi diesel engines used in the Clio range, 65, 80 and 100 bhp - does the 65 bhp one have a turbo charger? I know the 100bhp one has one as my friend has just taken delivery of one but not sure about the smaller powered models. What made me think is that 65bhp doesn't sound much for a turbo diesel. Also are all these cambelt engines? If so then perhaps a good reason to avoid considering the difficulty in changing the belt and potential damage.
Thanks

1. Not sure about the turbo issue.
2. They are all cambelt engines.
3. Belts no harder to change or more likely to snap than any other make.
|

They are all turbos, re 65 bhp, it is healthy for a 1.5 though the turbo boosts the torque peak and spread mainly.
|
There all turbo 65 an 80 turbos are the same excel for a boost valve spring but there the same turbos realy.
65 hp though on a 1.5 is possible without a turbo but it would be very smoky and never get made to pass emmisions.
Yep all cambelt though 72k/ 5ys they need changing.
Belts are cheap to make and keep dealerships with potential work thats why they don't change. The V10 VW engine has gears and a few other ngines have gears but there expensive to make hence there not used much.
Changing the belts is a £500 delership job its only 5 hrs to do though.

On a side note. Does anybody know if the dCi engines fitted to the Nissan Almera are belt or chain driven? I know the 2.2Di engine fitted to the Almera is chain driven, but what about the Renault sourced dCi's? Thanks.
|
Apparently the Primera dCi engines are not Renault units
|
|
The only dCi Nissans to use Renault engines (so far anyway) are the Micra and the Primastar van. The Primera and X-Trail 2.2 dCi is defintely a Nissan engine. No current Renault dCi's use chains.
|
From Parkers, about the engines avaliable for the Almera: "Two petrols and one diesel. 1.5 petrol is the most popular - fast enough for owners' expectations and 42mpg. Original 2.2 Di diesel is underpowered and not economical enough, but the latest 2.2 dCi (borrowed from Renault) has much more pulling power and is available with 112 and 136bhp."
OK, so assuming the 2.2 litre engine they claim is dCi isn't from Renault. Is it chain or is it belt driven?
|
As far as I am aware, the 2.2 dCi engine in Nissan cars is NOT a Renault engine. It is has a chain driven cam whereas all Renault dCi's use belts.
The only exception to this is the Primastar van, which is a (very) thinly disguised Renault Trafic.
|
"2.2 dCi (borrowed from Renault) has much more pulling power and is available with 112 and 136bhp."
no they are not - wrong statement. and if they were they would have considerably more oommph than 112 and 136bhp

The 2.2 dci renault is chain driven. Not belt. Although with renaults its simply a matter of phoning your local renault mechanic or parts specialist with your registration number(they can tell who built it and exactly what it is from this!)
Also the comment by edd that 65 is possible without a turbo.. 85 is possible without a turbo (1.9) and non turbo always smoke less not more. This is even comfirmed at mot time as turbo are allowed a higher smoke particle per million(look in the haynes manual)The whole point of a turbo is engine efficientency eg more power more mpg. still not much point with only 65bhp too much cost not enough pay back. I guess people just like turbos and these sell better. Usually the on dci (with the same engine size)all the power levels are controlled simply by ecu mapping. Everything else being the same engine wise.But the gearbox will have different ratios..... (buy a diesil magazine and speak to a tuning specialist they will be diffinitive on what can and cannot be done.)

"The 2.2 dci renault is chain driven."
All belts - unless they've changed the spec recently. The 2.2dCi in the Nissan is chain driven but that's not a Renault engine.
"Usually the on dci (with the same engine size)all the power levels are controlled simply by ecu mapping."
There are other differences, for example the 106 1.5dCi has an intercooler and dual vane turbo.
|
The 2.2dCi Nissan engine is a pile of junk. Very prone to expensive intercooler failure.
It's a modified Renault unit, with many Renault parts.
Nissan have managed to take a marginal design and turn it into an utter horror story. One to avoid.

So too, IMO, are the Renault DCi units. Had one in a Clio and it was nothing but trouble. Unrefined and noisy too, with an EGR valve that needed replacing so regularly you'd think it was a disposable part. Urgh. Save yourself a lot of time and hassle, and get a Kia Rio with the chain-cam diesel - less "stylish" than a Clio, but people will spend less time "admiring" your car as it's less likely to be stationary waiting for the AA to arrive. It's also got 110bhp as standard, almost double the base-model Clio's power output.

Very possibly. I have more experience with the Nissan dCi than with the Renault engines, although of course what folk say about the Renault engine is far from rosy.
I do know one Renault Megane owner whose 1.9dCi turbo failed TWICE in 30,000 miles. That really is unacceptable.
Funnily enough I know 3 people with Nissan 2.2dCis who have had no issues (two X-Trails and a Primera), but two more who have suffered a turbo failure and turbo/intercooler failure respectively -- the latter was about £1700 to fix IIRC.
Common fail engines are too iffy to get my vote anyway, but these dCis seem worse than most, whether they be Renault or Nissan.
|

I've heard a lot of criticisms levelled at the dCi engines, but that one's a first.
I had a 1.5 dCi Megane that was smoother and more civilised than a lot of petrol engines. Ditto the 1.9 in the Scenic.

On a cold morning my ex's Clio DCi was noisier than her previous Pug 205D. It smoothed out around town when it warmed up, but because it was the gutless 65bhp version it needed to be worked to get anywhere, so often sounded noisier than necessary. Plus, to end up with, it got through the EGR valves so fast I had no idea what its "normal" sound was. I gave Renault the benefit of the doubt, but it was such a horrible car in the end that I'll be avoiding them like the plague now.

It's interesting. My last company ran a fleet of 32 1.5dCi Meganes (106 PS versions) and not one had any major mechanical problem over 3 yrs and 100,000 miles (give or take). I also have the complete service printout from our Scenic from Renault UK's computer system, and apart from two minor non-engine related electrical niggles (sunroof and door switch), the car hasn't given a single problem in 43,000 miles.
I think the EGR problems are more common on cars driven around town, which of course on a Clio is a pretty shocking limitation. Certainly all the Meganes above, and our Scenic have had regular long-ish runs from new.
But I really am sorry to hear of your problems. I've only had one thoroughly unreliable car (a VW Polo) and it's such an awful feeling.

It appears that the latest Renault dCis are shared with Nissan, and are all chain-cam, starting with Laguna.
Time will tell whether they've finally ironed out all the bugs with these things.
|
|
Only the 2.0 dCi is chain driven. 1.5, obsolete 1.9 and 2.2 all belts.

Hi there, i have a clio DCI but its the 65bhp version, im a mechanic and have tried phoning renault but the dont have a clue with my problem
i would like to know the differances between my engine and the 80 and the 101hp engines. so that i may rob bits of them to put on mine, is it just an electrical differance or is there add ons such as intercoolers and differant turbo's???
many thanks

As far as I remember, when the '80' came out it had a variable geometry turbo, and possibly different injectors which would probably mean different ecu software too. It may have an intercooler also, you'd see that by checking under the bonnet of one.
|

|

106 has an intercooler, different turbo and ECU settings etc. Not worth the hassle for a bit more oomph. Just get the 80 chipped if you must go faster...
