High-performance 1,4-liter turbo engine in the new Astra

High-performance 1,4-liter turbo engine in the new Astra

The aluminum block itself weighs ten kilograms less than the forged steel block of the current 1,4-liter turbo engine.

• All-aluminum: four-cylinder petrol unit from the latest generation engines Opel

• Immediate response of gas delivery: dynamic and low fuel consumption

• Modern technologies: direct fuel injection and turbocharging for increased efficiency

• Memorable event: Sentgothard's 1.4 millionth engine - XNUMX-liter turbo engine.

The full name of the new Opel engine is 1.4 ECOTEC Direct Injection Turbo. The new Opel Astra will premiere at the Frankfurt International Motor Show (IAA) in September. The four-cylinder, turbocharged, direct injection, four-cylinder engine with central injectors will be available with two maximum outputs of 92 kW / 125 hp. and 107 kW / 150 hp. This all-aluminum unit is technologically linked to the recently introduced 1.0 ECOTEC Direct Injection Turbo turbine, known from Opel ADAM and Corsa. In fact, the new 1.4-liter four-cylinder is the big brother of the one-liter three-cylinder engine, which has received high praise from the press since its introduction in ADAM ROCKS and the new generation Corsa. Both engines belong to the so-called small gasoline engine family - a group of high-tech units with a displacement of less than 1.6 liters. They play a key role in the largest engine offensive in Opel history, which includes the release of 17 new engines between 2014 and 2018.

Best-in-class: Opel's new four-cylinder engine purrs like a kitten

PDuring the development phase of the 1.4-liter engine, special attention was paid to the dynamics of the car and the response to the gas supply, and this with the lowest possible fuel consumption. The engine reaches its maximum torque of 245 Nm very early, with the maximum level available in the range of 2,000 to 3,500 rpm. It offers the perfect combination of driving pleasure and performance. According to preliminary data, the powerful turbo engine with the Start / Stop system will consume less than 4.9 liters of gasoline per 100 kilometers in the combined cycle (114 g / km CO2). Thus, a 1.4-liter turbo engine will outperform even two-liter units in quality and will be able to replace them at all power levels. Once again, the engineers paid particular attention to reducing noise and vibration during the development phase, as was the case with the XNUMX liter three-cylinder engine. The engine block is designed to create minimal resonance effects, the crankcase is divided into two parts, the exhaust pipes in the cylinder head are integrated with noise reduction technology, the valve cover has a sound-absorbing design, high pressure injectors. pressures are isolated from the head and the valve drive circuit is designed to run as quietly as possible.

“Our new 1.4-liter turbocharged four-cylinder with direct injection and central injector is part of a new range of small petrol engines, and its qualities are expressed in the words“ powerful, efficient and cultured ”. The all-aluminum block not only protects the environment but also sets new standards in comfort, ”says Christian Müller, Vice President, Engine Power, GM Powertrain Engineering Europe.

Ease of existence: a new dimension of efficiency

The new 1.4 ECOTEC turbocharged direct fuel injection engine weighs less for the car. The aluminum block itself weighs ten kilograms less than the forged steel block of the current 1.4-liter turbo engine and perfectly matches the goals of the new high-performance Opel Astra. In terms of efficiency, the new turbocharged 1.4 engine delivers full power: to save weight, especially moving parts, the crankshaft is a hollow casting, the oil pump has low friction and operates on two levels. pressure. The entire engine is designed to run on 5W-30 low friction motor oils. All these measures provide exceptional efficiency.

While Opel's three-cylinder engines are typical of the 'downsize' philosophy (smaller, lighter, more efficient), for the new 1.4-liter four-cylinder Opel engineers speak of 'the best choice' or the perfect balance of efficiency in all operating modes.

Commemorative Event at Szentgottard

The 1.4 ECOTEC Direct Injection Turbo petrol engine is produced at the Opel plant in Szentgotard and has already become the occasion for a landmark event for the Hungarian plant. The eight millionth engine rolled off the assembly line at Zentgotard, which of course was an all-aluminum four-cylinder that will debut with the new Opel Astra in September.

“We have an engine plant in Hungary that is world-class flexibility and plays a key role in our manufacturing strategy. Congratulations and a big thank you to the whole team here - eight million engines is something to be very proud of and I am confident that we can celebrate more memorable events here in the not too distant future, ”said Peter Christian Cuspert, Vice President of Sales and After Sales service. at the Opel Group, who attended the celebrations with Mark Schiff, CEO of Opel / Vauxhall Europe, members of the Hungarian government and local officials.
