Mercedes-Benz brings diesel efficiency to petrol engines with CGI tech
Posted on Wednesday 7 November 2007



Mercedes-Benz has shown that ultra-efficient motoring doesn’t have to be limited to compact diesel and hybrid cars with the launch of its new E350 CGI and second-generation direct petrol injection system. Compared to the regular E350, the fuel consumption of the E350 CGI is lower by around 10% per hundred kilometers, and with 292hp (215kW) this unit also makes 20hp (15kW) more output available.


Fuel consumption figures for the new E350 CGI came in at just 27mpg (8.7L/100km), and despite this frugality the executive saloon still accelerates to 100km/h from rest in just 6.8 seconds and reaches an electronically controlled top speed of 250km/h.

Mercedes has also begun sales of its new E300 BLUETEC diesel, which ranks as the world’s cleanest diesel in its class. To achieve this status, the clean-diesel features an oxidizing catalytic converter and a particulate filter to ensure effective exhaust gas aftertreatment. Power is slightly down over the existing E320CDI, coming in at 211hp (155kW). The combined consumption figure for the E300 BLUETEC stands at 32.7mpg (7.2L/100km).

I reaqd somewhere they are also launching this in the CLS- pretty interesting stuff.

Given the average internal combustion automobile engine only converts roughly 20% of its energy into useful power, there seems be some room to move here- althouwell in theory anyway

Love the equation of less fuel + less emissions = more power

 

That's pretty darn good for a 3700lb car with close to 300HP engine.

 

How comes more and more car makers are moving to FSI which is more fuel efficient and generates more horsepower, except Honda ?

 

While Honda is typically late to the game, they regularly exceed everyone's expectations. We'll see it sometime, and when we do it will likely be the best iteration of the technology.

...or not.

Who knows what Honda is thinking; I sometimes wonder if they possess any logic (or direction, for that matter).

 

I have feeling it's because the gains over what they already have are minimal and it costs money to design/implement this stuff. Or they plan to skip straight to their combo gas/diesel design. Their entry into the diesel side was late but they have some of the most advanced ideas - like meeting the US emission regs without urea injection.

 

Honda used to be the best engine builder creating normally-aspirated car engines with unrivaled hp-per-litre figure. Now look around. More and more auto makers are building similar application engines with matching hp-per-litre figure simply by using FSI technology. In comparison, Honda is stagnant for the past few years in maintaining the lead and reputation as the best engine builder. Honda doesn't seem like it has plans to develop technology similar to FSI, to further boost the enigne output for all it's "small displacement" engines.

 

Very cool
