Vauxhall’s all-new 2.0-litre CDTi diesel engine made its debut at the 2014 Paris Motor Show today, with 170PS and 400Nm.
As Vauxhall continues to roll out its new powertrain lineup, the new state-of-the-art unit will be revealed in the Insignia and Zafria Tourer. The new engine will replace Vauxhall’s current 2.0 CDTi (163PS) diesel engine at the top of the range.
This fuel-efficient, Euro 6-compliant engine produces over 5% more power and 14% more torque while lowering fuel consumption and CO2 emissions.
Because of Vauxhall’s persistent focus on’sound engineering’ methods to reduce NVH, the engine is likewise exceptionally quiet and smooth (noise, vibration, harshness). The noise level of the engine has been decreased by five decibels.
The new engine has the same 85PS per litre power density as Vauxhall’s 1.6 CDTi ‘Whisper Diesel’ engine. From 1,750 to 2,500 rpm, impressive torque of 400Nm is accessible, and maximum power of 170PS is available at just 3,750 rpm.
Thanks to Vauxhall’s BlueInjection Selective Catalytic Reduction system, the new 2.0 CDTi runs as clean as a petrol engine. BlueInjection is a post-treatment that eliminates NOx from the exhaust fumes of an engine.
“Vauxhall’s Head of Carline Brand, Stuart Harris, stated, “This smart engine makes an ideal match for our top vehicles, like the Insignia and Zafira Tourer.” “It ranks among the best diesels in its class due to its great power density, refinement, and economy.”
The new 2.0 CDTi is the first in a new family of big diesel engines developed in-house by a worldwide team of engineers in Turin and Rüsselsheim, with support from engineers in North America, and will be available next year. It will be built in Germany at Opel/Kaiserslautern Vauxhall’s engine factory.
“Vauxhall Chairman and Managing Director Tim Tozer stated, “This superb new powertrain is part of the company’s 4 billion investment in product and powertrain research, which is helping to bring 23 new cars and 13 new engines to market.” “Vauxhall needs this new huge diesel engine because a large number of consumers have chosen the 2.0-litre CDTi engine.”
Following the introduction of all-new 1.6-litre petrol and diesel engines, as well as a 1.0-litre three-cylinder petrol powertrain, this 2.0-litre CDTi unit is the latest stage in Vauxhall’s powertrain offensive.
The freshly built combustion chamber, re-profiled intake ports, and new fuel injection system with 2,000 pressure and up to 10 injections per cylinder cycle are all key to the engine’s improved performance. This results in more power, greater fuel atomization, and quieter operation. More than 80 computer design simulations were run on the combustion chamber alone before the best five were chosen for hardware development.
An electrical actuator for the variable aspect turbine is used in the VGT (variable geometry turbocharger), which provides a 20% faster boost reaction than a vacuum actuator. The VGT and intercooler’s extremely small design also reduces the air volume between the turbocharger and the engine, resulting in faster boost pressure build-up. The turbocharger is water-cooled for durability, and an oil filter is installed at the oil inlet position to help prevent bearing wear.
For maximum efficiency, the VGT and exhaust gas recirculation (EGR) module have been built as a single system. The EGR module is built around an unique stainless steel radiator idea that offers over 90% cooling efficiency. The closed loop control of an integrated, water-cooled EGR bypass valve reduces pressure drop and improves NOx/PM trade-off under transient driving conditions, while also improving HC and CO emissions management.
From the start, a consistent improvement in NVH characteristics under all operating situations was a major need for the new engine. Even before the first prototype engines were manufactured, several CAE acoustic optimisation cycles were run on each component and sub-system.
Two high-noise-emitting locations at the top and bottom of the engine were the subject of architectural changes. Noise is reduced thanks to a new aluminium cylinder head design that includes a decoupled, plastic cam cover with separated fasteners and a sealing gasket. A single shell cover consisting of sound-absorbing material is also placed around the intake manifold.
A new balancer shaft module, made of high-pressure die-cast aluminum, is installed at the bottom of the engine. It has two counter-rotating shafts that can reduce secondary order engine vibrations by up to 83 percent. One of the balancer shafts is driven by a helical gear on the crankshaft, which is geared to drive the other shaft. The lack of a drive chain eliminates the potential of rattle noise, and scissor gear control provides smooth gear teeth meshing. After careful consideration, simple bearings were chosen over roller bearings for the balancer shafts to further reduce NVH and weight.
The oil pan’s design is also new. A two-piece design has replaced the earlier single-piece solution, with a lower sheet metal pan connected to an upper part made of high-pressure die-cast aluminum. Several analysis loops were used to acoustically optimize the internal and external ribs of both portions, further improving NVH performance.
- acoustically designed ribs in the cast iron cylinder block; individual balancing of the VGT compressor and turbine wheels; enhanced teeth-meshing on the timing belt and decoupled mounting points for its cover; increased teeth-meshing on the timing belt and decoupled mounting points for its cover
- As a result of all of these design changes, the new engine produces less noise throughout its operating range and is five decibels quieter at idle than its predecessor.
Since September 2015, the new 2.0 CDTi with Vauxhall’s BlueInjection SCR technology has met Euro 6 emissions regulations.
BlueInjection is a post-treatment that eliminates NOx from the exhaust fumes of an engine. AdBlue, a non-toxic solution made up of urea and water, is injected into the exhaust gas flow just before the SCR catalyst and just after the diesel particulate filter. The solution is quickly transformed to ammonia, which the SCR catalyst absorbs. In a chemical interaction with ammonia, nitrogen oxide in the passing exhaust gas is selectively reduced to harmless nitrogen and water vapor.
The AdBlue solution is held in a tank that may be topped up as needed by a nozzle adjacent to the vehicle’s gasoline filler cap, which is available at filling stations and Vauxhall dealerships.
Who makes the Ecotec diesel?
GM and its Adam Opel AG branch were kind enough to fly a few American motoring journalists to Germany recently. What is the explanation for this? The United States will not be able to test engines.
The engines are GM’s all-new Ecotec turbodiesels, which come in 4-cylinder 2L and 2.2L configurations. According to GM, the Ecotec lineup is the first to use both direct (in-cylinder) fuel injection (DI) and 4-valve-per-cylinder technology. By nearly every standard, the Ecotecs are flawless. The reason why American journalists were flown over the Atlantic to drive them is a little more hazy, especially since North American sales aren’t part of the strategy.
First, there are the engines: The 2L Ecotec is a low-pressure turbodiesel with a reasonable 82 horsepower (for European driving habits). The AlliedSignal Garret turbocharger is used in the “high-charge” 2L Ecotec, which produces 100 horsepower. The 2.2L variant with high-charge produces 115 horsepower.
The horses aren’t really the story with most of the new generation of DI turbodiesels; it’s the torque. The Ecotec, like the majority of DI automobile turbodiesels we’ve tested, pulls like a freight train. The light-pressure 2L produces 136 ft.-lbs. (185 Nm), the high-charge 2L produces 151 ft.-lbs. (205 Nm), and the 2.2L Ecotec produces 192 ft.-lbs. (260 Nm).
The best part is that the peak occurs between 1,900 and 2,500 rpm in the case of the massive 2.2L engine. If that wasn’t enough, there’s also a lot of flexibility: GM claims that 90 percent of the 2.2L’s peak torque is available between 1,400 and 3,750 rpm.
The 2L Ecotec engines are available in the Vectra (excellent) and Omega (sturdy but decent), whereas the 2.2L version is only available in the Sintra minivan, which I did not test. For the time being, only manual transmissions are available, but Jorg Steyer, assistant staff engineer, project center diesel, at Opel’s Technical Development Center Europe, believes automatic/Ecotec combinations may be available in the future – and that performance will not be compromised.
There are some lovely, creative elements, such as the exquisite “valve-bridge” valvetrain design, which uses a single rocker arm to open both inlet and exhaust valves, reducing friction and allowing the use of a single overhead cam. And if you only have time to see one assembly factory, make it the Ecotec plant in Kaiserslautern. It’s highly automated, astonishingly clean, and cheery; in the meantime, seeing the robot place all the cylinder head bolts into their precise slots – all at once! – may provide all-day pleasure.
New-generation diesels aren’t going away because they’re simply too good. Are American automakers merely waiting for our environmental regulators to wake up?
