Smart Fortwo CDI diesel engine swap?

[rmay635703]

I’ve often wondered how you would get a smart CDI detuned and running stand alone

Even into something slightly larger than a Metro, under those circumstances, this engine could work.

Well, hadn't Diesel engines been outlawed for small cars in my country, I'm sure a similar option could serve right for most taxi drivers. On a sidenote, that 2-cyl 0.8L turbodiesel which Maruti Suzuki used to make and which seemed to be comparable to the Smart CDi 3-cyl on most aspects could eventually be a reasonable option for small sedans such as the Fiat Cronos which has been increasingly popular among Brazilian taxi drivers.

cRiPpLe_rOoStEr, just had to look that 2-cylinder turbodiesel up on youtube. Sounds funny, kind of a small motorcycle and tractor combined.

Had them been available in Uruguay along the 1.0L 3-cyl gasser, it would be quite tempting to smuggle one to Brazil...

I know it is extremely off topic, but how are the VAG TDI engines compared to the MB CDI engines (around 2009). Reliability and FE wise.

A friend of mine owns a bmw 520 model year 1999 if i recall correctly and he says that the parts are common in many models and years. But that is not so with VAG cars which have different sensors/parts for most model year and subgroup cars. Making it almost impossible to find non oem parts. Which in turn makes it much more expensive to maintain.

VAG engines are quite modular, so it's not impossible to use parts of a different model-year. Plus the aftermarket support makes adaptations easier.

That 0.8L Suzuki diesel is the cat’s meow.

The engineers were tasked with developing a low-maintenance engine with high fuel efficiency, compliant with current and future emissions standards and able to fit in Suzuki’s full range of small cars.


They responded with a powerplant making 48 hp, 92 lb.-ft. (125 Nm) of torque at 2,000 rpm and delivering fuel economy of 64.9 mpg (3.6 L/100 km), which Maruti Suzuki claims is the Indian market’s highest.

The diesel weighs just 198 lbs. (90 kg), achieved by using an aluminum engine block and lightweight components. A counterbalance shaft normally would be needed to curtail noise from the block, but that would have increased the overall size of the engine. The solution was to increase the height of the block.

To curb vibration, the engineers chose a compression ratio of 15.1:1 instead of the usual 16.5:1. To compensate for the power deficiency resulting from the lower compression, two fixed-geometry turbochargers were used in place of a costlier variable-geometry turbo. This achieved comparable performance within the available budget and size of the engine block.

Supplier Bosch helped in replacing a common-rail fuel-injection system and air-to-air intercooler by developing a reservoir of air, again saving both space and money. A double camshaft with 2-valve arrangement was used in place of a single cam, and a high-pressure fuel pump meters fuel injected into each cylinder.

A belt drive for camshaft is relatively quiet, but wear and tear is high and frequent replacement is required. The engineers instead adopted a chain drive that requires more lubrication but uses less-expensive, more effective mineral oil in place of synthetic oil.

To contain costs, 97% of the DDisS125’s parts were locally sourced.

“We have developed a compact engine with excellent fuel economy,” says C V Raman, executive director-design development and engineering for Maruti Suzuki. “It was tough to meet the requirements of containing emissions (and) noise, vibration and harshness – but we have met them. We have made the small car fuel-efficient with a green engine. And there is no lack of power.”

It will never see the light of day in the U.S.A.

Too bad Maruti pulled the plug entirely on Diesel vehicles. Well, even though this engine had been applied to more platforms than the 3-cylinder one fitted to the Smart ForTwo, which could be supposed to increase the economics of scale, it was phased out due to the implement of Bharat Stage 6 emission rules (had been only available with Bharat Stage 4 certification) after its availability was confined to the Super Carry trucklet. Well, considering the budget-constraints and weight saving measures regarding the development of this engine, it sounds quite stupid that so many excuses are made by European automakers in order to phase out most of their Diesel offers. The displacement-biased tax structure usually enforced outside the NAFTA zone would actually favor smaller turbodiesels such as those 0.8L ones, also due to their smaller packaging enabling some easy fitment of emissions-control devices now widespread such as the DPF and LNT (which is a better alternative to those small engines than SCR and easier to implement on lower-output and small-displacement engines). Doing the math, the 47hp/92lb.ft. version would be great even for some small cars available in my country which don't feature any Diesel version not even for export anymore...

I guess this could be a nice recipient for such engine swap
