Dacia Broadens Fuel Efficient and Low Emission Offerings With LPG and E85 Engines, new 1.2L Gasoline Unit

Dacia, a member of the Renault group, is broadening its offerings of fuel-efficient and low-emissions engines. During 2009, Dacia will introduce the Sandero and Logan 1.4 LPG, Logan MCV 1.6 LPG, and the Sandero 1.6 E85 bioethanol. Sandero and Logan will also be available with a new gasoline engine, the 1.2 16V 75 hp, with CO2 emissions of 139 g/km.

LPG. The 1.4L LPG (75 hp / 56 kW) and 1.6L LPG (90 hp / 67 kW) engines reduce CO2 emissions by up to 12% compared with gasoline power, and offer lower emissions of criteria pollutants.

The Dacia LPG vehicles are dual-mode gasoline/ LPG gas vehicles (the driver only has to activate a switch to select the petrol or gas mode), and are 60% quieter than diesel-powered vehicles. The Sandero 1.4 LPG has a range of up to 1,200 km (746 miles) with a full tank of gasoline and a full tank of LPG.

The LPG fuel tank, built with steel and composite materials, is extremely crash resistant and is equipped with five safety accessories: a non-return valve, an 80% tank-fill limiter, fuel flow limiter, solenoid and shut-off valve.

There are some 32,000 refueling stations that serve LPG in Europe.

E85. The 90 hp (67 kW) 1.6L E85 flexfuel engine emits up to 70% less well-to-wheel (WTW) CO2 emissions compared with an all-gasoline engine. The Sandero 1.6 E85 delivers WTW emissions of 130g CO2/km running on sugar beet/wheat-based E85 fuel as produced in France, and 60g CO2/km with sugarcane-based E85 fuel as available in Sweden, according to Dacia.

Dacia benefits from Renault’s expertise in the bioethanol field. Renault has been manufacturing and commercializing Flex Fuel engines running with E100 ethanol since 2004.

Engine modifications include sodium-filled valves in the engine that are extremely resistant to high temperatures, optimized cylinder head cooling and oil jet-cooled pistons. Performance is identical to that of the 1.6L gasoline engine.

1.2L Gasoline Engine. The Sandero 1.2 16V and Logan 1.2 16V emit 139g of CO2/km, with combined cycle fuel consumption of 5.9L/100km (40 mpg US). Development work has enabled the idle speed to be lowered to 650 rpm (instead of 750 rpm) for a fuel consumption gain in built-up areas of between 2 and 3%. It is the first Renault engine to run with such a low idle speed. Servicing intervals are every 30,000 km (18,641 miles) or two years.



On the LPG engine, are they not giving up efficiency by maintaining compatibility with gasoline? Doesn't LPG have a higher octane than gasoline? Wouldn't a LPG only engine operate at a higher compression ratio?


Yes to all three questions.
I know an all NG car, if tuned right, can have greater power and range than its gasoline version inspite of NG having less BTUs so I suspect the same is true for LPG - but don't quote me on that.
