Test drive the 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 of Opel engines
• Immediate response of gas delivery: dynamic and low fuel consumption
• Modern technologies: direct fuel injection and turbocharging for increased efficiency
• Memorable event: Sentgothard's eight millionth engine is a 1.4-litre turbo engine.
The full name of the new Opel engine is 1.4 ECOTEC Direct Injection Turbo. The premiere of the new Opel Astra will take place at the Frankfurt International Motor Show (IAA) in September. The four-cylinder positive turbocharged direct injection engine with centrally located injectors will be available with two maximum outputs of 92 kW / 125 hp. and 107 kW / 150 hp This all-aluminum unit is technologically related to the recently introduced 1.0 ECOTEC Direct Injection Turbo, known from Opel ADAM and Corsa. In fact, the new 1.4-liter four-cylinder engine is the big brother of the one-liter three-cylinder engine that received high praise from the press after its introduction in ADAM ROCKS and the new generation Corsa. Both engines belong to the so-called family of small gasoline engines - a group of high-tech units with a displacement of less than 1.6 liters. They are playing a key role in the biggest engine offensive in Opel's history, which includes the launch of 17 new engines between 2014 and 2018.
Best-in-class: Opel's new four-cylinder engine purrs like a kitten
ПDuring 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 structure, 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 engine with direct injection and central injection is part of a new line of small gasoline 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, VP 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 in moving parts, the crankshaft is a hollow cast, 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 "downsizing" philosophy (smaller, lighter, more efficient), for the new 1.4-liter four-cylinder engine, Opel's engineers talk about "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, which is world-class in 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'm sure we'll be able to celebrate more memorable events here in the not too distant future,” said Peter Christian Kuspert, VP Sales and Aftermarket service. at the Opel Group, who attended the celebrations along with Mark Schiff, CEO of Opel/Vauxhall Europe, members of the Hungarian government and local officials.
