The new Lamborghini V12 Engine reveald

Lamborghini reveals the new 6.5L V12 engine and the new ISR gearboxLamborghini L539 ISR, key points of the heir to the Murcielago, for which it now seems certain to use the name Aventador (and Jota) and will be presented at the next Geneva Motor Show in March 2011.

Lamborghini V12 engine

The new Lamborghini 6.5 liters V12 engine

The new Lamborghini V12 engine with cylinder banks at 60 degrees, 6.5 liters and no direct injection delivers 700 bhp (700 PS / 515 kW) at 8250 rpm and 690 Nm (509 lb-ft) of torque at 5500 rpm and has been completely redesigned, introducing technologies that will become standard on future models of the torus also and a-square with a bore of 95 mm and stroke of 76.4 mm at 8250 rpm the pistons travel at 21 m/s, a rate lower than the Murcielago’s V12 L537.

Lamborghini V12 engine Specs

The base is made of aluminum alloy and silicon, with open-deck structure with steel cylinder liners, were also reduced internal friction. Dry sump lubrication was used, which is necessary to counter the lateral acceleration mainly seen on the track, with eight fuel pumps and especially a smaller vertical dimension, which has helped to lower the propeller of 60 mm and thus improve the distribution weight of the car. The cooling system has been optimized, with a dual circuit variable management to optimize the heating of the engine and catalyst.

The variable intake has 4 individual throttle bodies and a bypass valve to obtain the best compromise at all speeds and optimize the delivery, while the exhaust made for hydroforming is made of 3 to 2 in 1 design, with 4 2 pre-catalysts and catalysts and is equipped with a silencer with split most larger volume and a smaller one: an electronic control valve uses a combination that suits the driving conditions, without forgetting the essential “voice” worthy of a Lamborghini V12 engine.

The new 6.5L V12 engine will be assembled entirely in Sant’Agata and declares a weight of 235 kg, for a ratio of 3 kg/CV is up 665 mm, 848 mm wide including the collectors and 784 mm long.

Lamborghini ISR gearbox

The Lamborghini ISR gearbox is a rather important development in the broadcast robot, made by Italian Ricardo: the new robotic system speeds 50% higher than in many dual-clutch without substantial increases in weight. Shifting Rods Independent System makes it possible to simultaneously engage a gear and its relationship to the next through synchronizer carbon fiber control rods operated by individuals. The result is an improvement of 40% in the exchange rate changed from EGear on the Gallardo, with a total weight of the transmission of only 79 kg.

The control rods are a total of 4, moved by a hydraulic valve with 7 to 60 bar, managed to turn an electric pump and a hydraulic dual disc clutch. Three modes are available: the “Road” is geared to the comfort and automatically inserts the reports, the “Sport” improves shift times and select higher engine speeds, while the “Race” mode combines the Launch Control and enables the highest speed of change .

The full transmission, fully renovated, is handled by sending 00 to 60% of torque to the front axle differential with Haldex, thus maintaining a feeling of pure rear-wheel drive, but not giving up the ability to better manage the available 700 bhp.
