List of Discontinued Volkswagen Group Diesel Engines - Three-cylinder Diesels - 1.2 R3 PD TDI 3L

1.2 R3 PD TDI 3L

This inline three-cylinder Turbocharged Direct Injection (TDI) diesel engine is the powerplant of the Volkswagen Lupo 3L and Audi A2 3L, with a low fuel consumption of only 2.99 litres per 100 kilometres (94.5 mpg; 78.7 mpg) - hence the "3L" tag. It is based on the 1.4 TDI version, but the cylinder block is made of aluminium alloy, and some of the other components are lighter.

class: EA188, parts code prefix: ???, ID codes: ANY, AYZ
engine configuration & engine displacement
inline three-cylinder (R3/I3) Turbocharged Direct Injection (TDI) turbodiesel; 1,191 cubic centimetres (72.7 cu in), bore x stroke: 76.5 by 86.4 millimetres (3.01 in × 3.40 in), stroke ratio: 0.89:1 - undersquare/long-stroke, 397.1 cc per cylinder, compression ratio: 19.5:1
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)
Garrett GT1541V turbocharger, 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 Düse (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)
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
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%
Audi A2 3L (ANY:- A2: 03/01-08/05), Volkswagen Lupo 3L (ANY: 06/99-11/00, AYZ: 11/00-07/05)
