Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

The Ford 4.4 TD is a diesel V8 engine developed and built by Ford Motor Company.It has a power output of 340 PS (250 kW; 335 hp) and 700 N⋅m (516 lb⋅ft) of torque. As with the other AJDs, it has a compacted graphite iron block that reduces weight while increasing engine block strengt
The 4.4 L variant is built in Ford's Chihuahua Engine plant in Mexico. Much speculation in the United States has focused on this engine as a possible Diesel entrant in the F-150 pickup truck and Expedition SUV. [2] It was announced that the new F-150 engine was to be based on this engine and enlarged to 4.4 L, but that program was later cancelled.
The MaxxForce 7, also known as the 6.4 L PowerStroke in 2008-2010 model year Ford Super Duty trucks, is a 6.4 L turbo-diesel V8 engine. The engine has a sequential turbocharger system, utilizing a high pressure and low pressure turbo, with only the high pressure turbo being a VGT (variable geometry turbo).
The first engine to bear the Power Stroke name, the 7.3 L Power Stroke V8 is the Ford version of the Navistar T444E turbo-diesel V8. Introduced in 1994 as the replacement for the 7.3 L IDI V8, the Power Stroke/T444E is a completely new design, with only its bore and stroke dimensions common with its predecessor (resulting in its identical 444 ...
The 4.8L and the 5.3L are smaller truck versions of the LS1 and were designed to replace the 305 and the 350 in trucks. The 4.8L and 5.3L engines share the same Gen III LS-series engine block and heads (upper end) and therefore, most parts interchange freely between these engines and other variants in the LS family.
In 1989, Honda released the VTEC system. [13] While the earlier Nissan NVCS alters the phasing of the camshaft, VTEC switches to a separate cam profile at high engine speeds to improve peak power. The first VTEC engine Honda produced was the B16A which was installed in the Integra, CRX, and Civic hatchback available in Japan and Europe ...
If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the ...
