Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and ...
Better fuel distribution and better fuel charge inside the combustion chamber; During the injection process the fuel gets evaporated, cooling the cylinder chamber; Cooling effect of the pressurized fuel allows for use of a lower octane fuel leading to a cost savings for the end user; Higher compression ratios, which translates into more power
The Ford EEC-III single-point fuel injection system, introduced in 1980, was another early digital fuel injection system. [ 53 ] [ 54 ] These and other electronic manifold injection systems (using either port injection or throttle-body injection ) became more widespread through the 1980s, and by the early 1990s they had replaced carburettors in ...
The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938.. This engine was in high demand during WWII, necessitating a dramatic increase in output: about 57,000 6-71s were used on American landing craft, including 19,000 on LCVPs, about 8,000 on LCM Mk 3, and about 9,000 in quads on LCIs; and 39,000 ...
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
Director, Operational Test & Evaluation Official Seal. The Director, Operational Test and Evaluation (DOT&E) is the principal staff assistant and adviser to the US Secretary of Defense on operational and live fire test and evaluation activities involving U.S. Department of Defense weapons systems.
In 2007 - 2010 (2008 -2011 trucks), the Detroit Diesel 14L engine was modified to meet new emissions standards and went to a dual ECM configuration (DDEC VI). This engine ran higher compression, higher injector pressure and a DPF exhaust filter. The block and crank remained the same as the older 2004-2006 engine models.
The Yamaha DT125 is a motorcycle produced by Yamaha Motor Company that was first launched in 1974 as the DT125A [1] and is still sold in some markets to this day. The model designation DT indicates that it is a two-stroke, off-road-styled motorcycle, it has a raised exhaust, handlebars with cross members, universal tires, and adequate ground clearance for an off-road enduro motorcycle or trail ...
