Mercedes F1 W05 - engine installation 08 April 2014
Locating the internal combustion engine on a 2014 Formula One car is akin to finding a needle in a hay stack, but beneath all those ducts and coolers there really is a 1600cc V6. This drawing highlights the key elements of the engine packaging and illustrates why maintaining these cars is so much more work than in previous seasons.
1: Where the exhaust's primary pipes meet up into the tail pipe.
2: The connection from the tail pipe to the turbo.
3: With the engine sitting so low in the chassis, Mercedes have included this raised stiffening rib between the front engine-to-chassis mounting and the interface between the engine and gearbox. This helps maximise torsional stiffness, something vitally important to an F1 car's performance, as the cornering loads from the front to rear axles are all fed through the chassis and engine.
4: One of the many coolers required to maintain the temperatures of the hydraulic oil, gearbox oil, engine oil, water, ERS battery pack and control unit and the intercooler for the forced induction system.
5: A small duct that connects to an exit hole in the top of the engine cover, to assist in cooling one of the many components beneath.
6: A further duct and cooler, probably the gearbox cooler based on its size.
7: The connection from the cold side of the turbo to the airbox itself, where the air pressurised by the turbo is fed into the engine.
