2005 Australian International Motor Show: FPV's Emission Possible

Staff, Thursday October 13, 2005.

Its complete new BF model line, which includes the GT, GT-P, Pursuit and Super Pursuit that are powered by the high-tech quad-cam 5.4-litre Boss 290 V8 and the F6 Typhoon and F6 Tornado with the F6 270 Turbo 4.0-litre in-line six-cylinder, all comply with the strict Euro III emission regulations months ahead of their formal introduction by the Federal Government.

The modifications introduced to meet the new emission regulations, and combined with the addition of the six-speed automatic, has resulted in better fuel economy for both the Boss 290 V8 and F6 270 Turbo engines.

?High-performance cars are perceived to be the most harmful to the environment because of their inherent nature, but that is not necessarily the case,? said David Flint, Managing Director of Ford Performance Vehicles.

?The advances made in emission control over the last decade have been quite dramatic. Our engineering partners at Prodrive were handed the challenge of making sure our vehicles complied with the toughest emission regulation ever imposed on Australian-built cars. They have achieved the task and counteracted the tougher restrictions without any loss in the performance outputs of our engines.

?These modifications have also resulted in improved efficiency of our engines. It?s a double win for our customers.?

EURO III

All FPV models in the new BF model range now comply with Euro III emission regulations as dictated by the new Australian Design Rule ADR 79/01 that is due to come into effect for all new petrol-powered passenger vehicles sold from January 1, 2006.

The strict new regulations enforce a significant reduction in the production of harmful Hydrocarbon (HC) emissions from 0.6 grams per kilometre to 0.2 grams per kilometre, reducing Carbon Monoxide (CO) from 4.0g/Km to 2.3g/Km, as well as reducing Oxides of Nitrogen (NOx) to 0.15g/Km. Under the previous Euro II regulations NOx levels were recorded within the Hydrocarbon output.

A major pathway in achieving the requirements of the new regulations is the introduction of a number of strict tests, including for the first time a sub-zero emission test at minus seven degrees centigrade, that all emissions are recorded from engine start-up, an evaporative heat soak test that measures emissions from the fuel system under high-ambient temperatures and that the catalytic converters must still perform above the regulations for longer than 80,000km.

ON BOARD DIAGNOSTICS

As a part of the Euro III standards, all vehicles must also be fitted with a sophisticated on-board diagnostics (OBD) system that constantly monitors the emission control systems to ensure the vehicle always complies with the regulations.

The OBD is linked to the engine management system with a number of sensors that monitor the condition and performance of specific components related to controlling the emission output.

The OBD system measures the emission output through the addition of an extra oxygen sensor that monitors the operation of the catalytic converters and provides more accurate control of the air-fuel ratio. There is also as a misfire monitor that detects any changes in the acceleration of the crankshaft.

If either of the these sensors record an event that results in emissions exceeding those prescribed under the Euro III regulations, the OBD system logs the event within the ECU. If a similar event occurs within the same driving period, or if the system detects the issue when the engine is re-started, the driver is made aware of a potential issue via the engine warning light on the instrumental panel.

?The adoption of On Board Diagnostics through the Euro III regulations provides our customers with greater peace of mind that their vehicle is operating correctly at all times,? Flint adds.

?The system is completely invisible to the owner up to the point when a potential issue has been recorded. If this occurs, the owner should take the vehicle to their FPV dealership to have the event investigated.?

BOSS 290

The high-tech quad cam Boss 290 ? the only V8 production engine to be built in Australia ? has a number of upgraded features that coincide with the introduction of the new BF range.

In conjunction with compliance with the Euro III emission regulations, another new design standard will be introduced from 2006: a reduction in drive-by noise (ADR 83/00) from 77dB to 75dB. To achieve this, the 5.4-litre quad cam Boss 290 V8 is now fitted with the dual-entry ram airbox that was first introduced on the F6 Typhoon and F6 Tornado and a bold new twin-exhaust system exclusively available on the GT and GT-P.

The dual-entry ram airbox provides more efficient airflow into the induction system. This offsets the increase in exhaust back pressure imposed by the emission regulations, and also provides a significant reduction in induction noise. The airbox volume has increased from five cubic litres to 13 cubic litres.

The new twin exhaust system on the GT and GT-P not only lifts the aesthetic presence of the iconic V8-powered models, but also generates a traditional muscle car-inspired exhaust note. The system has four-into-one extractors from each bank of cylinders joining into a twin 2 ¼-inch exhaust with an intermediate silencer box. The exhaust gases pass through new tri-flow silencers before exiting via the six-inch twin-outlets that feature a trapezoidal design reminiscent of iconic muscle cars of the 1970s.

The tri-flow silencers replace conventional absorption silencers and create a definitive V8 exhaust note while being able to comply with the ADR 83/00 drive-by noise regulations.

Other detail changes include the addition of an extra knock sensor, camshaft timing improvements and relocating the front oxygen sensor from the manifold to the catalyst downpipe. The twin knock control system ensures efficient engine management under a wider range of conditions. The camshaft timing adjustment has resulted in a lower idle speed and better idle stability. And the relocation of the oxygen sensor improves the accuracy of measuring the air/fuel ratio for the OBD system.

The engine management system also required modifications to the calibration to meet the Euro III standards as well as the fitment of the dual-entry ram airbox and twin exhaust system.

Despite the restrictions imposed by the Euro III regulations, Prodrive?s powertrain engineering team has maintained the power and torque outputs of the 5.4-litre quad cam Boss 290 V8. It produces maximum power of 290kW at 5500rpm and 520Nm of torque at 4500rpm.

The Boss 290 is now up to 2.6 per cent more fuel efficient, with the GT and GT-P manual sedans recording 14.9 litres/100km/h under official ADR requirements for combined city/urban driving cycle. The lower gearing of the six-speed automatic records 15.0 litres/100km in GT and GT-P and 15.1 in Pursuit.

F6 270 TURBO

The intercooled and turbo-charged F6 270 Turbo six cylinder engine has also received a host of detail changes in line with the introduction of the Euro III emission standards.

As with the Boss 290 V8, it now features twin knock sensors and a revised engine calibration.

It also receives new camshaft profiles on the dual variable cam timing system with five degrees longer duration on the inlet and 10 degrees longer on exhaust to maintain consistent power output at high engine speeds.

The F6 Typhoon also has a new exhaust outlet, replicating the trapezoidal design on the GT and GT-P with the single pipe on the right-hand side.

Peak power and torque outputs have been maintained, with the DOHC 4.0-litre turbo-charged six-cylinder producing peak power of 270kW at 5250rpm and maximum torque of 550Nm ? the highest torque figure of any Australian-built production engine ? produced from 2000-4250rpm.

The F6 270 Turbo is up to 3.6 per cent more fuel efficient compared to the BA MkII model with the six-speed manual versions of the F6 Typhoon and F6 Tornado recording official fuel economy figures of 13.5 litres/100km/h. With the six-speed automatic, both models have fuel economy figures of 13.0 litres/100km/h.
