Volvo has slashed the emissions of the V70 and S80 models, with diesel variants hitting the sub-120g/km of CO2 category for the first time.
Some of the carmaker’s larger vehicles, the estate V70 and saloon S80 are fairly unique among their class in achieving such low C02 emissions at just 119g/km.
The achievement means that the Swedish carmaker has over the past year or so, succeeded in delivering five models with emissions below 120 g/km.
Volvo’s trademark ‘greenest in the range’ DRIVe badge includes the new improved Volvo V70 and S80 variants along with green versions of the C30 (99 g/km), S40 (104 g/km) and V50 (104 g/km) models.
“There has been a swift pace of development since the launch of our first 119-gram models in Paris in autumn 2008. The fact that we have now brought two of the larger models in our range below the magical 120 gram limit shows that few of our competitors can match us when it comes to offering customers increasingly green cars,” said Volvo Cars President and CEO Stephen Odell.
The new 119-gram versions of the Volvo V70 and S80 are equipped with a 1.6-litre diesel engine and manual gearbox. They have a power output of 109 hp and maximum torque is 240 Nm.
Volvo’s driveline experts have employed two techniques to reduce the CO2 emissions from the previous 129 g/km to 119 g/km for both models.
Firstly it adopted ‘intelligent battery recharging’, whereby the control system only allows the alternator to charge the battery when the engine is operating at low load, for instance when driving downhill. The carmaker also reduced the friction for the belt that drives the alternator and air conditioning compressor. The redesign of the tensioner pulley and alternator pulley results in lower fuel consumption and lower emissions.
“Smart battery recharging is the most important measure. It is primarily thanks to this that we have dipped below the 120-gram level that gives car owners tax breaks and other benefits in a number of European countries. What is more, one might say that we offer the normal driver one free tank of fuel a year,” says Ulf Nordström, Technical Project manager at Volvo Cars.
Consuming just 4.0 litres of fuel per 100 kilometres, the increase efficiency means that someone driving 15,000 km a year will save 60 litres of diesel. Translated into carbon dioxide emissions, the saving is 150 kg over a year.

14 years in the U.S. there is a revolutionary patent for the
elimination of C02 in cars, reducing 50% consumption of gasoline in
cars.
U.S. Patent elimination of CO2, reducing fuel consumption, whose do not

New spark plug -plasma spark plug reduce 70% fuel reduce CO2 zero-O-

For years now, I have wondered where and when the next Edison with a
bright idea will appear and invent a “lean, green, driving machine”.
I have finally found such a man. He lives in Farmington Hills,
Michigan, and his name is Robert Krupa
We have all heard the saying, “If something sounds too good to be
true, itsually is”. The amazing new spark plug designed by Mr Krupa,
which he named “FireStorm”, is the exception to this rule.
named “FireStorm”, is the exception to this rule.
I know that when it comes to buying spark plugs, they are all
basically the same except for the price. So, why make the same except
for
the price. So, why make
a big deal about another new spark plug?
Fire Storm Capabilities
First, let look at what Krupa FireStorm spark plugs give an
internal
combustion engine:
More horsepower;
44-50% increase in mpg;
Dramatic decrease in emissions.
Second, let see what FireStorm plugs eliminate:
Smog pump;
Catalytic converter;
Radio frequency interference (RFI) and the use of resistors in the
centre
electrode;
Gap growth;
Exhaust gas recirculation (EGR) systems;
Misfire/hesitation/detonation/stutter and stumble.
How, you may ask, is all this achieved? In a word, plasma. The
revolutionary design of FireStorm spark plugs creates an electric
plasma
that fills the entire combustion chamber like a firestorm. It allows
you
to take an internal combustion engine from the standard 14.7:1
air-to-fuel
ratio to an incredibly lean 24:1,30:1,40:1. At this ratio, all the
air/fuel mixture
is burned much more efficiently without increasing heat, thus
giving
an
engine more power and fuel economy while creating much less
pollution.
The bad news is that you can buy a set of FireStorm spark plugs
anywhere right now.

The question why the motor industry into this patent into this
solution does not want to invest?

As you can see what is revolutionary for many is unknown. The automotive industry is quite fond of the old spark plugs with low efficiency and does not intend to do anything to introduce new applications patents. The American indifference to FireStorm Spark Plug led to the collapse of the leading companies in the U.S.. And it is a struggle with a reduction in CO2 and decrease fuel consumption, or envy, that someone from outside the automotive industry has created a spark plasma for cars powered by gasoline.
