cylinder block & crankcase
cast aluminium alloy (saving 16 kilograms (35 lb)); simplex-chain-driven balance shaft and oil pump, four main bearings
piston and piston rods
Alcan aluminium pistons, trapezoid bearings shared with rods
cylinder head & valvetrain
cast aluminium alloy; two valves per cylinder, 6 valves in total, each with two concentric valve springs, belt-driven single overhead camshaft (SOHC)
aspiration
Garrett GT1541V turbocharger [Family 15, 41 millimetres (1.6 in) compressor wheel (exducer diameter), VNT (Variable-Nozzle Turbine)], side-mounted intercooler (upright),
water cooled exhaust gas recirculation (EGR) system integrated in heating cooling circuit (not in 1.4 TDI)
cooling system
increased engine coolant temperature of 90 °C (194 °F) (in 1.4 TDI: 85 °C (185 °F)), oil cooler integrated in engine cooling circuit (heating cooling circuit in 1.4 TDI)
fuel system
camshaft-actuated Pumpe D[ch252]se (PD) direct injection Unit Injectors, injection pressure up to 2,050 bars (29,733 psi) (approx. 180 bars (2,611 psi) pre-injection, min. 300 bars (4,351 psi) main-injection), increased recirculated fuel temperature from underfloor cooler of 60 °C (140 °F) (in 1.4 TDI: 30 °C (86 °F))
engine management
Bosch EDC 15P (variant spelling: EDC 15+) electronic engine control unit (ECU) (some few old ones EDC 15 only)
exhaust system
lightweight construction: reduced wall thickness and steel sheet exhaust manifold (instead of cast-iron),
one near-engine-mounted catalytic pre-converter, one main catalytic converter and an end muffler
(instead of one underfloor catalytic converter, one underfloor muffler and an end muffler attached to 1.4 TDI)
starter
strengthend Bosch starter motor (12V, 150A, 1800W with 9 tooth pinion) for stopp-start system with quick-start-function and voltage stabiliser for airbag-system, radio and instrument cluster
dimensions
100 kilograms (220 lb)
DIN-rated motive power & torque output
SPORT mode:
45 kilowatts (61 PS; 60 bhp) @ 4,000 rpm; 140 newton metres (103 lbf·ft) @ 1,800-2,400 rpm, 80% available from 1,300 rpm
ECO mode:
33 kilowatts (45 PS; 44 bhp) @ 3,000 rpm; 120 newton metres (89 lbf·ft) @ 1,600-2,400 rpm, "redline" is 3,000 rpm (instead of 4,800 rpm)
idling speed
reduced while the car freewheels (above 13 kilometres per hour (8 mph)) to 770 rpm (otherwise 850 rpm)
mean effective pressure
14.8 bars (215 psi) (in SPORT mode)
mean efficiency in driving cycle
slightly over 30%
