Ferrari Enzo Engine

The Enzo Ferrari is powered by a naturally aspirated 65° V12 engine, with a completely new design based on experience gained in Formula 1.

This very special V12 features a total capacity of 5,998 cc, a bore of 92 mm and a stroke of 75.2 mm with an 11.2:1 compression ratio. The cylinder head design reveals its Formula 1 origins through pentroof combustion chambers with 4 valves per cylinder, and inlet and exhaust ducts to maximize the exhaust coefficients and combustion speed.

Timing is by triple geared belt drive on a central transmission actuating 4 overhead camshafts for direct valve control through hydraulic tappets. Intake and exhaust manifold timing is continuously variable, thanks to high pressure hydraulic intervention of the four variable advances activated by the engine control unit.

The variable geometry inlet manifold is also borrowed from Formula 1, with a system of small telescopic pumps activated by hydraulic actuator, that allow the power and peak torque values to be maximized.

Electronic engine management is provided on each row of cylinders by a Bosch Motronic ME7 unit which controls the PFI multiple injection system, the drive-by-wire throttle valve and the single coils on each spark plug. Six knock sensors mounted on the cylinder block are designed to control knocking.
