The Lancia D50 was a Formula One racing car designed by Vittorio Jano for Lancia in 1954. The car's design made use of many innovative features, such as the use of the engine as a stressed chassis member, the off-centre positioning of the engine to allow a lower overall height, and pannier fuel cells for better weight distribution and aerodynamics.

A pusher aircraft is a type of aircraft using propellers placed behind the engines and may be classified according to engine/propeller location and drive as well as the lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft), Some aircraft have a Push-pull configuration with both tractor and pusher engines.
The so-called push/pull layout, combining the tractor and pusher configurations—that is, with one or more propellers facing forward and one or more others facing back—was another idea that continues to be used from time to time as a means of reducing the asymmetric effects of an outboard engine failure, such as on the Farman F.222, but at ...
The maximum axle load was reduced from 14.99 t (D50) to 14.30 t, which enabled it to operate on lighter secondary lines, previously inaccessible to the D50. Shorter Length: The D51 was 571 mm shorter than the D50 to fit on standard 60-foot (18.3 m) turntables common on branch lines, thus broadening its operational range.
Some OHC engines employ short rocker arms, also known as finger followers, [2] in which the cam lobe pushes downward on the back of the rocker arm to open the valve. In such a configuration one end of the follower is anchored (pivoting in place on a roller bearing), rather than having its fulcrum in the center like standard rocker arms.
Volvo D5 engine D5244T15 (), in 2015 model year Volvo XC70It is an all-aluminium five-cylinder engine with 20 valves and double overhead camshafts.In all but one late version it has a VGT turbocharger of the type VNT (variable nozzle turbine), common rail direct injection and cooled exhaust gas recirculation (EGR).
Target-type thrust reversal is commonly applied to low bypass turbofan engines or turbojet engines. In this kind of engine with low bypass ratio, the core part of the engine produces a significantly larger part of the thrust. Therefore, the airflow from the core part must be blocked in order to produce sufficient reverse thrust. [10]
A front mid-engine, rear-wheel-drive layout (FMR) places the engine in the front half of the vehicle but behind the front axle, which likewise drives the rear wheels via a driveshaft. Shifting the engine's center of mass rearward aids in front/rear weight distribution and reduces the moment of inertia , both of which improve a vehicle's handling .
