Peugeot 607 HDi 170 - the executive car that gives you more for your money

Model range

The 607 HDi 170 is available in only one trim level - Executive - but with a very comprehensive standard specification including:

2.2 litre HDi 170 / DW12BTED4 – DPFS engine

The 2.2 litre HDi DPFS (Diesel Particulate Filter System) engine is the fourth engine produced out of the co-operation between PSA Peugeot Citroën and the Ford Motor Company. It strengthens further the HDi diesel engine range developed jointly since the signing of the co-operation agreement in 1998. This engine replaces the previous Euro 3 2.2 litre HDi engine fitted to the 607 from which it is evolved. It has 4-cylinders and is fitted with a 16-valve cylinder head with twin overhead camshafts and has a capacity of 2179 cm3.The torque produced by the engine and its throttle response at low engine speeds have been the subject of particular attention; as a result, at only 1000 rpm the engine develops 150 lb ft of torque which then increases to 209 lb ft at just 1250 rpm. In addition, the engine has a very flat torque curve which provides excellent driveability at all engine speeds (with more than 265 lb ft of torque at 3000 rpm).

It produces its maximum power of 170 bhp at 4000 rpm with a maximum torque of 277 lb ft at only 1500 rpm. In other words 54% more than with the previous generation 2.2 litre HDi diesel engine at this engine speed. During the design of the engine, a number of ambitious objectives were set:

• Obtain the dynamic performance and driveability of a larger capacity engine while ensuring reduced levels of fuel consumption and CO2 emissions (confirmation of Peugeot technological strategy of “downsizing”), as well as a high level of environmental performance (Euro 4 and DPFS).
• Ensure a compact and easily adaptable engine suitable for use with different platforms.
• Contribute actively towards the protection of pedestrians by lowering the under bonnet height of the unit.
• Ensure excellent noise and vibration levels aligned with the customer expectations in these segments, achieved in particular by the presence of two counter-rotating balancing shafts.

A new design of combustion chamber, third-generation common rail injection technology and increasing injection pressure to 1800 bar, combined with sequential twin parallel turbochargers, are the main technological innovations that have made it possible to achieve this technical challenge.

THE SEQUENTIAL TWIN PARALLEL TURBOCHARGERS
The use of sequential twin parallel turbochargers is a world first on a 4-cylinder diesel car.  The system (patented with Honeywell Turbo Technology) consists of two identical, small-diameter turbochargers. At low engine speeds, a single turbocharger ensures engine responsiveness. It is then supported by a second turbocharger, which starts to operate in parallel between 2600 and 3200 rpm according to the applied load and atmospheric conditions. The entire range of engine speeds is therefore covered. The system is controlled entirely by the engine management electronic control unit (ECU). In addition, the low inertia and small size of the turbochargers reduces response time and improves throttle response.

PRINCIPLE


At low engine speeds a single turbo-charger provides the engine boost. The incoming air is drawn in through the air filter and through a circulation bypass control valve (A).

The air is then drawn into the turbo-charger compressor C1, which is driven directly by the exhaust gases rotating the turbine (T1).

The two control valves (B) and (C) are closed, isolating the second turbo-charger, until the engine management electronic control unit (ECU) decides the extra engine boost is required.

From approximately 2600 rpm the two control valves (B) and (C) are opened by the engine management (ECU) and the circulation bypass control valve (A) closes.

With the control valve (C) open the exhaust gases exiting the engine are now directed to the turbo-charger turbine (T1), driving the first unit and the second turbo-charger turbine (T2). With both turbines driving their respective compressors (C1 & C2) the air drawn in through the air filter is now pressurised “twice” increasing the engine’s boost pressure.

The use of this technology enhances both driveability and, in particular, ensures excellent torque availability. This enables the driver to drive at lower engine speeds, thereby reducing fuel consumption.

ECCS (EXTREME CONVENTIONAL COMBUSTION SYSTEM)

THIRD-GENERATION COMMON RAIL INJECTION SYSTEM
 
The all-new, third-generation Bosch common rail injection system now has an injection pressure which has been increased to 1800 bar (1350 bar for the previous engine).

The higher injection pressure is controlled by new piezo-electric injectors in which each nozzle is equipped with seven apertures (instead of five previously) with a diameter of 135 microns. This allows the number of individual injections per cycle to be multiplied (potentially up to six times) and ensures meticulous uniformity of the diesel injection spray pattern. With the air/diesel mixture optimised in this way, combustion is more complete and more uniform, thereby reducing emissions at source.

ENVIRONMENTAL PROTECTION

This new 2.2 litre HDi 170 engine is a worthy standard bearer in terms of environmental protection. It should be remembered that through its basic design, the diesel engine ensures excellent thermodynamic efficiency and that the fitment of an HDi direct injection system increases this performance still further.

Thanks to the very high injection pressure of the common rail system and the extremely fine spray pattern of the diesel fuel into the combustion chamber, it allows more uniform and more complete combustion and significantly reduces emissions at source.

In addition, the twin turbochargers and the exhaust gas recirculation system contribute actively to environmental protection and meet the requirements of the Euro 4 emission standard.

The combination of the new combustion chamber design, with the increased injection pressure of 1800 bar, results in a reduction of emissions of around 30% compared to the previous engine.

It is of, course, combined with the latest-generation diesel particulate filter system (DPFS) technology, which has a service interval of 120,000 miles.

ENGINE DESIGN

Compared to the previous engine, the engine’s overall height has been reduced by 4 cm. This makes the installation easier and improves particularly pedestrian impact protection by creating a larger space between the underside of the bonnet and the top of the engine. Creating this greater space under the bonnet ensures better energy absorption in the event of an impact.

IMPROVED NOISE AND VIBRATION PERFORMANCE

The patented design of the double-wall cylinder block improves the engine’s acoustic performance by 3dB, a level which will be noticed by both the driver and passengers.

The fitment of two counter-rotating balancing shafts, design of the engine mountings and the use of a dual mass flywheel also reduces engine vibration. In addition, a quick action throttle mounted in the inlet system is actuated when the engine is returning to idle to avoid any vibration when the driver stops the car.  

MAINTENANCE

A large capacity two-section oil sump allows the oil change intervals to be increased to 20,000 miles, from the previous engines 12,000 mile service intervals. Similarly, the dimensions of the drive belt and its engine accessories have been designed to be maintenance-free for the life of the vehicle.

Suspension, steering & brakes

The suspension consists of a pseudo McPherson type front strut assembly with a lower wishbone and a linked anti-roll bar and, a double wishbone multi-link assembly at the rear. Improved multi-valve shock absorbers are fitted to enhance comfort and road holding.

STEERING

Electro-hydraulic variable power steering is fitted which provides maximum assistance at low speeds; assistance is then reduced gradually as the vehicle speed increases. This provides steering which is both precise, responsive and enhances both driving pleasure and safety.

BRAKES

Braking is provided by front ventilated brake discs with a diameter of 330 mm and a thickness of 30 mm, and at the rear, non-ventilated brake discs with a diameter of 290 x 12 mm. The latest generation electronic stability programme (ESP) Bosch type 8.0, which guarantees simultaneously a high level of safety and driveability is fitted as standard. The traction control (ASR) and dynamic stability control (DSC) systems can be switched off for starting on slippery road surfaces, but automatically re-activates when the vehicle exceeds 30 mph. Emergency braking assistance (EBA), the activation of which is controlled automatically according to vehicle speed, is also a standard fitment.

Interior

The interior of the 607 is one of the most spacious in its class.  Whatever the temperature outside, bi-zone digital air conditioning with climate control, an athermic (heat reflective) windscreen and tinted glass ensure a relaxed environment inside.  The interior is trimmed in Astrakan black leather with aluminium detailing on the centre console. The electrically adjustable front seats make finding the ideal driving position very easy, especially as the driver’s seat adjustment can be memorised, as can the position of the rear-view door mirrors.

MOTORISED BOOT

A simple touch of the “boot” button on the remote control key fob causes the boot to open automatically in less than four seconds.  This operation is controlled by an electric motor with a rotary clutch acting on the support arm of the boot and assisted by gas struts.

Innovative technology

To enable the driver to communicate safely whilst on the move, the 607 is fitted with Peugeot’s integrated RT3 Telematics system which includes a radio / single CD player, GSM mobile phone and colour satellite navigation. From a list of key words, voice commands can activate the radio / CD, dial a phone number or find a destination. Remote controls mounted on the steering column allow the system to be controlled remotely without the driver removing their hands from the steering wheel.
The 607 also has an impressive in car entertainment system consisting of a 6 disc CD auto-changer combined with a JBL HiFi system. This system uses 8 high performance speakers and is controlled by a power amplifier which provides an output of 240W of music power.

Safety & security

The 607 is particularly well equipped in terms of passive safety, with eight air bags as standard: driver, passenger, front and rear side and curtain. The 607 is fitted with SMART twin generator and dual volume adaptive front airbags, the pressure and volume of which is controlled by the severity of the impact.

SECURITY

Deadlocks, laminated side glass, ultrasonic alarm, rolling code transponder immobiliser and alloy wheel locking bolts all help keep the vehicle secure. 

Automatic locking of the doors, boot and fuel filler cap as soon as the car reaches a speed of 6 mph, provides added peace mind for the driver and passengers. This function can be de-activated / re-activated as the driver chooses.
