The Adam Opel Will Get a Turbocharged 3-Cylinder
|   Friday, August 09, 2013
Ever since it was launched in the European market, the Opel Adam felt the need for more powerful petrol engines, capable to inspire and innovative its design and wide range of accessories for customization.

Starting with the next year the Adam Opel will benefit from a new engine, a 3-cylinder turbocharged engine, the first member of the new SGE range, the abbreviation of SmallGasoline Engine. The engine will be the first, from a large number of units with 3 or 4-cylinder, plus turbocharger, and will be available with displacements between 1 liter and 1.
liters.

The new 1 liter engine available on Adam will be able to deliver 115 horsepower and a torque of 165 Nm. Being a turbo unit, torque will be delivered early and on an extremely generous speed range of between 1800 and 4700 rpm.

The consumption figures haven't been officially announced, but Opel claims it will be 20 percent more efficient than the ongoing Astra which is equipped with the 1.6 liter naturally aspirated engine. Since the compact has an average consumption of 5.3 liters / 100 km, in the case of the little Adam we can expect at least 4.4 liters / 100 km.

Opel also expects the new engine family to deliver not only impressive fuel economy but also significantly lower than 100 g/km CO2 emissions.
The aluminum engine block, uses the latest direct injection tech coupled to a system of electronically controlled valves. It is not missing Soundproofing items, a modified acoustic exhaust, a turbocharger and a new intake system. These features would provide sophistication to the 4-cylinder unit, according to the official press release Opel.

Another big contributor to refinement levels is the installation of a balance shaft in the oil sump. A chain with inverted teeth makes it run for quietly, with the counter-rotating shaft spinning at crankshaft speed and being carefully mass-optimized to balance the vibrations a 3 cylinder unit produces.

Other noise reduction measures are: covers for the front and top of the engine, the intake manifold and camshaft housings, the crankshaft isolation with iron main bearing inserts, along with inverted teeth for camshaft drive chain, coupled with a low-hiss turbo compressor plus a lower oil pan in steel.

"In developing this small engine, we not only set out to minimize fuel consumption and CO2 emissions, we also wanted to demonstrate that three cylinders can be just as refined as four or more," says Dr. Matthias Alt, Opel's Chief Engineer, Small Gasoline Engines. "We tackled at source the balance, noise and vibration issues typical of conventional three-cylinder engines, and we're confident customers will be pleasantly surprised by the results. This is a very lively and refined three-cylinder engine which doesn't compromise on driving fun."

The program started with the launching of its first engines in new mid-size petrol and diesel families. The 1.6-liter turbo units are joined now by the 1.0 turbo, which is the first example of a new engine family one with smaller displacements. All these will be built at GM's new Szentgotthard plant in Hungary, where petrol and diesel engines will be made on a shared assembly line.
