Ferrari F116/F133 engine

The F116 engine family is a series of 65° DOHC V12 petrol engines produced by Ferrari since 1992. Introduced with the 456 GT, this engine had a displacement of 5.5 L and was a fresh new design who replaced the previous Colombo-derived F101 60° V12 engines used in Ferrari 412 four-seater.[1] A more performant variant named F133 debuted in 1996 with the 550 Maranello, replacing the F113 flat-12 engines.[2]

The production of the F116 ceased in 2003; in the same period the F133's displacement was increased to 5.7 L and lasted until 2011. It was then replaced by the F140 engine family.

All those engines featured dry sump lubrication and 48 valves driven by dual overhead camshafts per bank. The block and cylinder heads were constructed from light alloy, featuring Nikasil treated alloy cylinder liners.[1][2] A Bosch Motronic 2.7 combined fuel injection/ignition engine management system was initially fitted, superseded by a Motronic 5.2 unit in 1996[1] and by a Motronic ME7 system for the 5.7 L versions.

Motorsport

Some engineering companies built racing versions based on the F133A engine, without any support from the Ferrari factory. Those engines were used in various 550 GT racecars, most notably the Prodrive-developed 550 GTS who took many victories in the FIA GT Championship, the European Le Mans Series and the 24 Hours of Le Mans.

A factory 6.0 L racing version of the F133 engine was jointly developed by Ferrari and N.Technology for the 575 GTC.

Ferrari flat-12 engine

The Ferrari flat-12 engine family is a series of 180° V12 DOHC petrol engines produced by Ferrari from 1973 to 1996. Introduced with the 365 GT4/BB, this engine shared its construction with the flat-12 race-engines used in the 312B and 312 PB, but its displacement, bore & stroke, rods and pistons were the same as the Tipo 251 60° V12 Colombo engine powering the Daytona it replaced.Design and development of the new engine was overseen by Ferrari engineers Giuliano de Angelis and Angelo Bellei.The engine was the first flat-12 cylinder configuration fitted in a Ferrari road car and had factory type reference F102A. It had two valves per cylinder and twin overhead camshafts per bank, although these were now belt driven, instead of by chain as on earlier Ferrari 12-cylinder engines. It was fitted with two banks of two triple-choke Weber 40IF3C carburettors and an electronic ignition system. The block and cylinder heads were constructed from light alloy and featured wet sump lubrication.

In 1976 Ferrari launched a revised version of the BB, the 512 BB, with a flat-12 engine enlarged to 4943cc. Named F102B, it featured a dry sump lubrication system to help the car scavenge oil.In 1981 the 512 BBi replaced the outgoing model’s four triple-choke carburettors with a Bosch K-Jetronic mechanical fuel injection. The new engine got factory type reference F110A but otherwise it was mechanically identical to its predecessor.With the debut of Testarossa in 1984, the evolution of the flat-12 engine saw it equipped with four valves per cylinder: with 390 PS (287 kW; 385 hp) it was the most powerful engine mounted on a production sports car at the time of its launch. It maintained the same cubic capacity of 4943cc of the 512 BBi model, and had factory type reference number F113A. It was fitted with a Marelli Microplex MED120 electronic ignition system and Bosch K-Jetronic fuel injection. Export versions for United States, Canada and Japan had catalytic converter and KE-Jetronic fuel injection. European versions got those features in 1986 and the revised engine was known as F113B.The 1991 512 TR had an upgraded version of the engine used in the Testarossa, maintaining the same cubic capacity of 4.9 L, and had factory type reference number F113D. Changes were made to the porting, with redesigned inlet plenums and larger valves providing more efficient fuel/air mix ingress, whilst the fuel injection and ignition system were changed to a combined Bosch Motronic M2.7 system.For the 1994 F512M the engine was further upgraded with a lightened crankshaft, titanium alloy connecting rods, new pistons and a stainless steel low backpressure exhaust system.The flat-12 production ceased with the F512M, being replaced by the front-engined 550 Maranello which featured the new 65° V12 F133 engine.
