    Default Origin's of the Insignia's 2.0 Turbo Petrol Engine

    Folowing on from a thread over on the Vectra chat page, there has been some discussion about the origins of the Insignia's petrol 2.0 Turbo, I and others thought it was a development of the Vectra C Z20NET engine and some said it was derived from the Astra VXR engine Z20LEH.

    So I e-mailed the VXR brand manager at Vauxhall to get the details.

    His response is as follows :-

    "The 2.0 Turbo engine in the Insignia has most in common with the Vectra 2.0 C turbo Z20 NET. It is an L850 engine that is common with the Redline series in the States. its designator is A20NHT ( A is Euro 5)"

    For info from an Opel Blog Forum - a list of new Insignia engine designations

    A16LET Engine 1.6l turbo (Euro5, 190PS)
    A16XER Engine 1.6l (Euro5, 115PS)
    A18XER Engine 1.8l (Euro5, 140PS)
    A20DTC Engine 2.0l turbo-Diesel (Euro5, 130PS)
    A20DTH Engine 2.0l turbo-Diesel (Euro5, 160PS)
    A20DTJ Engine 2.0l turbo-Diesel (Euro5, 110PS)
    A20NHT Engine 2.0l turbo (Euro5, 220PS)
    A28NET Engine 2.8V6 turbo (Euro5, 260PS)

    I expect that the A20DTJ and A16XER lower-powered engines will not be offered under the Vauxhall marque.

    Thanks rushy, Got this info of wiki-

    A turbocharged direct injected (redubbed Spark Ignition Direct Injection) Ecotec was introduced in the 2007 Saturn Sky Red Line. Displacement is 2.0 L — 1998 cc (121.9 cu in) — with a square 86 mm (3.38 in) bore and stroke. Compression is 9.2:1 and maximum boost is 20.0 psi, delivering 260 hp (194 kW) at 5300 rpm and 260 lbft (353 Nm) of torque from 2500–5250 rpm. Engine redline is at 6300 rpm and premium fuel is recommended. The "Gen II" block is similar to the 2.4 L and also features VVT technology.

    Unique LNF features[1] include:

    * a twin-scroll turbocharger
    * gasoline direct injection
    * variable valve timing
    * sodium-filled valves
    * oil-cooled low-friction cast pistons

    This engine is used in:

    * 2007–present Opel GT
    * 2007–present Solstice GXP
    * 2007–present Saturn Sky Red Line
    * 2008 Chevy HHR SS
    * 2008-2009 Chevrolet Cobalt SS

    It will also be sold and used in:

    * 2009 Fisker Karma


    Looks like a shi2 hot engine, 20psi boost, Twin scroll turbo charger.

    Chevrolet cobalt

    SS Turbocharged

    2009 Cobalt SS turbocharged coupe

    The LSJ engine did not meet emissions requirements for the 2008 model year, and General Motors' contract with Eaton had expired.[15][7] The non-supercharged 2.4 L Cobalt SS also lost its Super Sport designation for the 2008 model year and was renamed "Sport". However, in fall 2007, a more powerful Cobalt SS was announced for the second quarter of 2008.[16] The car would be equipped with the 2.0 L, turbocharged, direct injected, VVT, LNF Ecotec engine, making 260 hp (194 kW) at 5300 rpm and 260 lbft (353 Nm) at 2000 rpm, and remain mated to the F35 5-speed manual transmission.[17] The engine had been introduced in a rear wheel drive application for the 2007 GM Kappa platform, which includes the Saturn Sky, Pontiac Solstice, and Opel GT.[18]

    Also new for the 2008 SS were SS-embroidered sport seats with suede-like UltraLux inserts, several new exterior colors, and wider 18-inch (460 mm) forged, split-spoke wheels with P225/40R18 Continental AG tires, reminiscent of those offered for the Chevrolet Corvette C6.[14] The car's electronics are also new, and along with greater assist in poor traction conditions, add a "no-lift-shift" feature which allows the driver to maintain turbocharger boost during upshifts. During a no-lift-shift, the driver shifts normally by depressing the clutch, but the accelerator pedal is held wide open.[14] Also new is "launch control", which feathers the throttle at roughly 4800 rpm until engagement of the clutch, allowing more consistent launches in competitive situations. To use the feature the driver presses twice on the traction control button which first turns off traction control, and then notifies the driver through the Driver's Information Center that the launch control of Competitive Mode has been enabled. However, turbocharged Cobalt owners have found that better times can be achieved while racing when the car is manually launched. These features help propel the car from 0 to 60 mph (97 km/h) in a class-leading 5.5 seconds, and a quarter mile time of 13.9 seconds at 102.5 mph (165.0 km/h)

    More info

    Turbocharger Description and Operation
    A turbocharger is a compressor that is used to increase the power output of an engine by increasing the mass of the oxygen and therefore the fuel entering the engine. This BorgWarner™ dual-scroll turbocharger is mounted on the exhaust manifold and the lightweight turbine is driven by the waste energy generated by the flow of the exhaust gases. The turbine is connected by a shaft to the compressor which is mounted in the induction system of the engine. The compressor vanes compress the intake air above atmospheric pressure, thereby greatly increasing the density of the air entering the engine. The turbocharger is capable of producing up to 20 psi or 1.40 bar, of power-enhancing boost.

    The turbocharger incorporates a wastegate that is controlled by a pressure differential, that is determined by the engine control module (ECM) by means of a PWM solenoid, in order to regulate the pressure ratio of the compressor. A compressor bypass valve also controlled by the ECM by utilizing a remotely mounted solenoid is integrated into the unit to prevent compressor surging and damage from vibrations by opening during abrupt closed throttle conditions. When the valve is open during closed throttle deceleration conditions, the bypass valve allows the air to recirculate in the turbocharger and maintain compressor speed. Within a calibrated range during the closed throttle event, or upon a wide open throttle command the valve will then close to optimize turbo response.

    The turbocharger is connected to the engine oiling system by a supply and drain tube and Mobil 1™ synthetic oil is installed at the factory. Synthetic oil is required for its friction-reducing capabilities and high-temperature performance. There is a cooling system circuit in the turbocharger that utilizes the engine coolant to further reduce operating temperatures.

    Charge Air Cooler Description
    The turbocharger is supported by an air-to-air charge air cooler (CAC) system, which uses fresh air drawn through a heat exchanger to reduce the temperature of the warmer compressed air forced through the intake system. Inlet air temperature can be reduced by up to 100C (180F), enhancing performance because cooler air is denser in oxygen and promotes optimal combustion. The CAC is connected to the turbocharger and to the throttle body by flexible ductwork that requires the use of special high torque fastening clamps. In order to prevent any type of air leak when servicing the ductwork, the tightening specifications and proper positioning of the clamps is critical, and must be strictly adhered to.

    Benefits of Dual Cam Phasing
    The camshafts of the Ecotec 2.0 liter turbocharged engine have camshaft position (CMP) sensors and CMP actuators that the ECM uses to accurately control the continuously variable intake and exhaust valve timing. This allows the combustion process to be optimized by the ECM to increase the response of the turbocharger, providing a more immediate feeling of power to the driver.

    Benefits of Gasoline Direct Injection
    In the Ecotec 2.0 liter turbocharged engine, the fuel is introduced directly into the combustion chamber during the intake stroke. As the piston approaches top-dead center, the mixture is ignited by the spark plug, thereby giving the name spark ignition direct injection (SIDI). SIDI allows the mixture to be leaner, with less fuel and more air at full power. SIDI also allows a slightly higher compression ratio, resulting in improved fuel consumption at part and full throttle.

    The fact that the fuel is injected after the exhaust valve closes allows particularly high valve overlap values in certain engine operating ranges. This enhances the turbocharger response time. This would not be possible in a port fuel injection (PFI) engine due to the fact that unburned fuel would escape through the open exhaust valve.

    Direct injection’s precise fuel delivery enables more complete combustion which reduces emissions particularly on cold starts.

    Electronic Vacuum Pump
    The purpose of the electronic vacuum pump is to keep the vacuum in the brake booster at an acceptable level under various operating conditions. The ECM monitors the input signal from the brake booster pressure sensor. When the vacuum in the brake booster is not in an acceptable range the ECM will command the relay ON that controls the vacuum pump.
