Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Lubrication for two-stroke engines is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply ...
In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre ...
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 ...
Upstream blending: Fuels are mixed in the liquid phase, one with low ignition resistance (such as diesel) and a second with greater resistance (gasoline). Ignition timing varies with the ratio of these fuels. In-chamber blending: One fuel can be injected in the intake duct (port injection) and the other directly into the cylinder.
The ancestor of Detroit Diesel was the Winton Engine Company, founded by Alexander Winton in 1912; Winton Engine began producing diesel engines in fall 1913. After Charles F. Kettering purchased two Winton diesels for his yacht, General Motors acquired the company in 1930 along with Electro Motive Company, Winton's primary client.
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.
With the stratified-charge application, the 3.0L V-6 will continue to employ direct fuel injection, but the injectors have been redesigned to spray under higher pressure later in the intake stroke, just before compression, and the fuel is shaped to arrive in certain areas within the cylinder to optimize combustion.
Its high specific power, high fuel efficiency and low exhaust pollution have made it a promising technology. As a compression-ignition engine, the fuel mixture ignites due to the increase in temperature that occurs with compression rather than a spark from a spark plug. [5] A PPC engine injects and premixes a charge during the compression stroke.
