The license agreement terminated in the late 1950s and the Nissan G engine was a more compact replacement, which in turn became replaced by the (below) Nissan H engines. The 1H would also be de-stroked from 89mm to 59mm to become the 1.0 L (990 cc) to create the Nissan C engine at the suggestion of former Willys-Overland engineer Donald Stone.
In the 1950s, Ford introduced a three-tier approach to engines, with small, mid-sized, and larger engines aimed at different markets. All of Ford's mainstream V8 engines were replaced by the overhead cam Modular family in the 1990s and the company introduced a new large architecture, the Boss family, for 2010.
The Hyundai D engine is a family of 3-cylinder and 4-cylinder diesel engines produced by Hyundai Motor Company under license from VM Motori. [ 1 ] The D-line of engines feature cast iron block and aluminum cylinder head, with belt driven single overhead camshafts operating four valves per cylinder.
With the help of geometrically variable turbo-charging system (albeit more maintenance) this also increases the engines' torque at low engine speeds (1,200–1,800 rpm). Low speed diesel engines like the MAN S80ME-C7 have achieved an overall energy conversion efficiency of 54.4%, which is the highest conversion of fuel into power by any single ...
HCCI engines have a small torque range, constrained at low loads by lean flammability limits and high loads by in-cylinder pressure restrictions. [ 7 ] Carbon monoxide (CO) and hydrocarbon (HC) pre-catalyst emissions are higher than a typical spark ignition engine, caused by incomplete oxidation (due to the rapid combustion event and low in ...
In the automotive industry, engine downsizing is the practice of utilizing smaller combustion engines over larger ones of the same power capacity when manufacturing vehicles. It is the result of car manufacturers attempting to provide more efficient vehicles that emit fewer emissions , [ 1 ] often mandated by legislative standards . [ 2 ]
Like several other Japanese makers, Mazda produced V-twin engines for their three-wheeled delivery vehicles of the 1950s. These were also used in some of the tiny keicars of the 1960s. These were essentially motorcycle engines, and were largely superseded by water-cooled straight-4 engines in a few years, except for in the Mazda R360 which ...
