Engine – Overview

Design and Function

B4204T6 is a direct injection 4-cylinder petrol engine with turbo and has double overhead camshafts and 16 valves.

The fuel system has a pump in the tank and a high pressure pump driven mechanically by the engine. This produces a high fuel pressure that enables direct injection in the combustion chamber.

The camshaft drive is chain driven and has mechanical tappets. The camshafts are equipped with Twin VCT (Variable Cam Timing).

The turbocharger's exhaust turbine is integrated into the exhaust manifold which is made of sheet metal.

Cylinder sequence starts with cylinder 1 at the engine's camshaft drive. The engine's ignition system is equipped with knock control with two knock sensors and an ignition system with direct-mounted ignition coils.

Diagnosis for monitoring exhaust-related components is performed via the data link connector.

B4164Tx is a transverse 4-cylinder, 1.6-litre gasoline engine with overhead camshafts based on the well-known B4164S3. The most significant new feature is the engine's cutting-edge gasoline-direct injection technology with turbocharger, which gives the following advantages:

• Fuel consumption and CO₂-emissions are reduced by up to 20 percent,
• plenty of power at low rpms and sporty response from the engine throughout the entire engine speed range,
• driving performance like that of a bigger engine together with the lower weight, compact dimensions and lower friction losses like those of an engine with smaller cylinder capacity.

B4164Tx has been modified in a number of ways compared to B4164S3:

• Gasoline direct injection instead of conventional fuel injection in the intake manifold.
• Turbocharger to increase torque and power.
• Four separate ignition coils - direct ignition instead of the common electronic ignition coil.
• 'Control when needed' of coolant temperature via

• an overflow valve and
• a shut-off valve.

The firing order is 1-3-4-2. The cylinders are counted from the front, i.e. number one cylinder is closest to the crankshaft's pulley.

From and incl. model year 2008 the cylinder block is die-cast instead of sand-cast. This has resulted in a new design of the cylinder block. The engine block and cylinder head are made of an aluminum alloy.

The engine block is of the type "Open Deck", which means lower weight and that a bigger area around the cylinder is exposed to cooling.

Meets standards for emission levels according to Euro 5.

The camshafts are driven by a ribbed belt.

B4164T has a maximum power of 132 kW (180 hp) and a maximum torque of 240 Nm between 1,600-5,000 rpm.

B4164T3 has a maximum power of 112 kW (150 hp) and a maximum torque of 240 Nm between 1,600-4,000 rpm.

The 1.6L Duratorq-TDCi (DV) diesel D4162T is a four-cylinder, 1.6-litre diesel engine from Peugeot. This is a transverse turbo diesel engine. It has a single overhead camshaft and 8 valves.

D4162T has a maximum output of 85 kW (115 hp) and reaches a torque of 270 Nm at 1,750 rpm.

The engine meets emission standards Euro 5.

To reduce CO2-emissions EHPAS (Electric Hydraulic Power Assisted Steering) is used, which contributes to lowering the engine's fuel consumption by its way of working.

The engine has a Contitech Common Rail injection system. The fuel filter includes a heating coil for use in cold climates. This heating coil is turned on automatically.

The EGR-valve is electrically controlled by the engine control module (ECM). EGR technology is used to reduce the exhaust temperature and thereby to reduce NOx emissions. This involves returning some of the exhaust gases to the combustion chamber.

The amount of exhaust gas returned is controlled by an EGR stepper motor and can thus be adjusted precisely. The exhaust gases returned are cooled by means of an EGR cooler before being fed into the induction manifold.

The turbo system on this engine consists of a turbo unit with a VNT (Variable Nozzle Turbine) which is controlled by a turbo control valve, which in turn influences a pressure box.

The fuel filter is mounted on a retainer directly on the cylinder head and is fitted with electric fuel preheating. The fuel lines are secured using snap-on couplings.

The engine is equipped with a catalytic particle filter that works without fuel additive.

The carbon particles that may remain in the exhaust gases after combustion are filtered out by allowing the exhaust gases to flow into the particle filter.

The engine is available in different versions. They are transverse, 5-cylinder 20 valve turbocharged engines with a cylinder volume of 1,984, 2,497 or 2,521 dm³. Depending on the variant different fuels are available; Petrol, Ethanol or biogas. The engine and transmission are pendulum mounted with a mounting on the engine which goes to the side member via a rubber bushing and an engine mounting on the transmission. There is a support point on the bearing mounting to take up the torque.

The engine has been developed by Volvo.

It is a 6 cylinder transverse in-line engine with a cylinder capacity of 3.2 L for naturally aspirated engines and 3.0 L for turbocharged engines.

After having been relatively unchanged since the introduction 0620, this engine family has been updated on several points. Most modifications have their basis in an effort to achieve lower fuel consumption and thus less environmental impact.

Engine power has increased, at the same time as fuel consumption has decreased.

• B6304T4: (ULEV2 Ultra Low Emission Vehicle): 300(US)/ 304 hp / 440 Nm
• B6324S4 (PZEV - Partial Zero Emission Vehicle): 230(US) 233 hp (torque unchanged 300 Nm)
• B6324S5 (ULEV - Ultra Low Emission Vehicle): 240(US) /243 hp (torque unchanged 320 Nm)

All of these engines meet the emission standards for Euro5.

The engines' idle speed is reduced to 590 rpm on all cars except XC90 which keeps 650 rpm.

The engine is extremely compact. When it was introduced it was the shortest 6-cylinder engine of 3.2 L on the market. Conventional straight 6-cylinder engines are too long to fit between the collision members in the engine compartment. The special design of this engine solves the problem.

The engine has an extremely short drive train, its length is only 625 mm from the front edge of the engine block to the rear edge of the carrier plate.

Great attention has been paid to creating a very rigid engine. Middle part, cylinder block and cylinder head have been structurally optimized to combine low weight with high rigidity.

Even the camshaft cover is structurally optimized.

The engine has double overhead camshafts and 24 valves.

Camshafts, AC-compressor, coolant pump and alternator are driven by an auxiliary unit drive, mounted on the back of the engine.

This placement of the auxiliary unit drive enables new possibilities for creating a good collision-protecting structure around the straight 6-cylinder drive unit. In the latest update of the engine family the servo pump has been replaced by an electrically driven pump (EHPAS), for more information, see Design and function.

The entire engine block and the cylinder head is made from aluminum.

The engine has a compact "pent-roof" designed combustion chamber and V-arranged valves. This gives optimal and fast filling and direct flushing via the inlet manifold followed by the combustion chamber (cross-flow) and the exhaust channel.

The squish surfaces together with the centrally positioned spark plug provide optimal combustion of the air/fuel mixture, low knock sensitivity and low, stable exhaust emissions.

The engine's firing order is 1 - 5 - 3 - 6 - 2 - 4. The firings occur every 120 degrees that the crankshaft rotates.
