SPAIN - The new Opel Astra to come equipped with the new Whisper 1.4 Turbo ECOTEC diesel engine.

• Petrol engine with four-cylinder, all-aluminum.
• Immediate response: dynamic throttle response and high performance.
• Advanced technology: direct fuel injection and turbocharging to achieve greater efficiency

Opel show in Frankfurt Motor Show the new engine 1.4 Turbo ECOTEC direct injection for the first time in the new Opel Astra. The compressed turbo four-cylinder with direct fuel injection core engine will be available with two power levels 125 hp / 92 kW to 150 hp / 110 kW.

This combination linked to this new aluminum engine with the recently introduced 1.0 Turbo ECOTEC direct injection and known ADAM and the Opel Corsa. In fact, the new 1.4-liter four-cylinder can be considered the older brother of three cylinders and a liter. 

Both engines belong to the family of small gasoline engines; a group of mechanical three- and four-cylinder 1.6-liter displacements below.

New reference: quiet four-cylinder engine as a whisper

It has paid great attention during the development of the 1.4-liter Turbo engine with high performance and dynamic response, while content is fuel consumption. 

The engine delivers maximum torque soon up to 245 Nm. The maximum is available between 2,000 and 4,000 rpm, an area surprisingly large. The conditions are perfect to combine driving fun with fuel efficiency.

According to preliminary data, the powerful turbo engine equipped with Start / Stop technology has a consumption of only 4.9 liters of gasoline per 100 km in combined cycle (114 g CO ₂ per km). 

Therefore, the 1.4-liter Turbo can compete in performance even with two-liter engines and replace. Engineers have paid great attention to the sound level and the performance against vibrations during the development of the new engine, as is already done in developing the engine of one liter and three cylinders. 

The engine block has been built keeping in mind the reduction of resonance, the oil pan is divided into two parts, the integration of the stock in the exhaust manifold is insulated, it has designed a cover of absorbing noise distribution. 

They have been decoupled injection valves and distribution chain has been cut to have a low concentricity.

"Our new turbocharged 1.4-liter four-cylinder with direct injection and core attributes responds to powerful, efficient and quiet. Made entirely of aluminum, in addition to being environmentally friendly, sets new standards in ride comfort, "says Christian Müller, vice president of GM Powertrain Europe.

For its construction, the new 1.4 ECOTEC turbo engine with direct injection adds less weight to the vehicle.Only aluminum engine block weighs 10 kilos less than the forged steel of the current 1.4-liter turbo being the perfect choice for the new Opel Astra and efficient. 

It is precisely in terms of efficiency where the new 1.4-liter turbo shows its technological advances. To make the engine as light as possible, the crankshaft is hollow, the oil pump is low friction and works with two levels of flow as needed. 

All the motor is designed to operate with low viscosity oils 5W-30. All these measures ensure high efficiency in fuel consumption.

While three-cylinder engines are the typical representatives Opel engines (smaller, lighter and more efficient) reduced engine, Opel engineers speak of "engine optimized" when, for example, speak of the perfect balance between efficiency high and low load the new 1.4-liter turbo four-cylinder.
