Lamborghini V10 - Specifications

Specifications

engine configuration

90° V10 engine; dry sump lubrication system

engine displacement etc.

5.0 — 4,961 cubic centimetres (302.7 cu in); bore x stroke: 82.5 by 92.8 millimetres (3.25 in × 3.65 in) (stroke ratio: 0.89:1 - undersquare/long-stroke), 496.1 cc per cylinder; compression ratio: 11.0:1

5.2 — 5,204 cubic centimetres (317.6 cu in); bore x stroke: 84.5 by 92.8 millimetres (3.33 in × 3.65 in) (stroke ratio: 0.91:1 - undersquare/long-stroke), 520.4 cc per cylinder; compression ratio: 12.5:1

cylinder block and crankcase

5.0 — cast aluminium alloy with integrated liners with eutectic alloy; 88 mm (3.46 in) cylinder bore spacing; forged steel crankshaft with split crankpins (to create even 72 deg firing interval with the 90 deg vee-angle)

5.2 — cast aluminium alloy; 90 mm cylinder bore spacing; forged steel crankshaft with shared crankpins (creating an uneven firing interval of either 54 deg or 90 deg separation)

cylinder heads and valvetrain

cast aluminium alloy, four valves per cylinder, 40 valves total, low-friction roller cam followers with automatic hydraulic valve clearance compensation, 2x chain driven double overhead camshafts (2xDOHC - two overhead camshafts per cylinder bank - 'quad cam'), continuously variable valve timing system both for intake and exhaust

aspiration

two air filters, two hot-film air mass meters, two cast alloy throttle bodies each with electronically controlled 'drive by wire' throttle butterfly valves, cast magnesium alloy variable geometry and resonance intake manifold

fuel system

5.0 — two linked common rail fuel distributor rails, electronic sequential multi-point indirect fuel injection with 10 intake manifold-sited fuel injectors

5.2 — fully demand-controlled and returnless; fuel tank mounted low pressure fuel pump, Fuel Stratified Injection (FSI): two inlet camshaft double-cam driven single-piston high-pressure injection pumps maintaining pressure in the two stainless steel common rail fuel distributor rails, ten combustion chamber sited direct injection solenoid-controlled sequential fuel injectors

ignition system and engine management

mapped direct ignition with centrally mounted spark plugs and ten individual direct-acting single spark coils; two Lamborghini LIE electronic engine control unit (ECUs) working on the 'master and slave' concept due to the high revving nature of the engine

exhaust system

5.0 — five-into-one exhaust manifolds for each cylinder bank

5.2 — 2-1-2 branch exhaust manifold per cylinder bank to minimise reverse pulsation of expelled exhaust gasses
