The small gasoline engine will make a big step forward

The gasoline engine is experiencing a renaissance. The reason: The global state emissions requirements in the medium term are on alternative drives can not be achieved.

Wuppertal. The gasoline engine is experiencing a renaissance. The reason: The global state emissions requirements in the medium term are on alternative drives can not be achieved. To the volume of electric and hybrid applications are initially too low. The supplier of "conventional" fuel-saving technologies therefore expect in the coming years, massive increases in sales. "With gasoline engines were the innovations in the past compared with the diesel so massive. This has however changed completely in recent times, "says Sebastian Schilling, development manager for the supplier Delphi Fuel Injection.

He convinced the future of the gasoline engine is optimized - possible double charging and reduces the capacity and number of cylinders. An important advantage of gasoline compared to diesel is its lower price. "The new petrol engine driving pleasure in offering affordable technology. This will raise its image value further, "Schilling is convinced. The diesel engine was settled for price reasons but always in higher vehicle segments, but this disadvantage it is to be even stronger.

Already the Euro-5 emissions standard that had made the diesel as compared to an equally powerful gasoline even more expensive. From 2014 to the current Euro-6 standard for this cost disadvantage will impact even more. In addition, the diesel passenger car due to the industrial logic to a "world car", the water is dug out, because developments alone for the stagnant European market are worth less and less. Toyota has therefore already set the course for the gasoline-hybrid technology. At Volkswagen, in turn, increases the share of TSI / TFSI engines.

Motor gasoline is catching up steadily
The distance of the gasoline engine to diesel will reduce significantly in the coming years, "says Schilling Delphi developers. "The homogeneous fuel injection and spray-guided injection now also offer considerable potential." Overall, he keeps the gasoline engine savings in fuel consumption by about 20 percent in a relatively short period of time possible. This brings the homogeneous injection three to four percent savings that the downsizing of engines will contribute around eight per cent to and use of one or more additional five percent were turbocharged possible. Would add further efficiency improvements such as smaller oil pump, electronically controlled fuel pump, a variable valve timing and spray-guided injection.

The decisive factor was the view of the overall powertrain system, says Schilling. "We are no longer just the individual components in the view of" Additional development would boost the gasoline obtained by its growing role as a standard drive in a hybrid vehicle. "A gasoline engine in the hybrid car is lighter, smaller, cheaper and produces less vibration than a diesel," Schilling called the benefits. Finally, the space was cramped in hybrid vehicles with its numerous electrical components are assembled. Demonstrate the high potential of the gasoline engine will soon prove to the new generations of modern three-cylinder gasoline engine. Among other things, to PSA, Renault, Nissan and Ford with new, powerful and fuel-efficient "mini-engines" shake up the volume segment.
