In line with the IDI diesel, the Power Stroke was offered in three-quarter-ton and larger versions of the Ford F-Series and Econoline product ranges. The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L).
These engines use an injection pump that is entirely mechanical, as was the standard for diesels of the day. The fuel system also utilizes indirect injection which made it quieter than mechanically direct injected engines. Both displacements use the Stanadyne DB-2 injection pump fed by a cam-driven lift pump.
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). High-pressure injection delivers power and fuel consumption benefits over earlier lower ...
The Power Stroke is *NOT* based on the only IH Gasser. There are two distinctive lines of enignes, the IDI and the Power Stroke, there was the 6.9 and 7.3 IDIs, they were the ones based on the gas engine, they were indirect injection, using pre-chambers connected to the main compression chamber, and had mechanical injection.
Injection pump for a 12-cylinder diesel engine An injection pump is the device that pumps fuel into the cylinders of a diesel engine . Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt ) that also drives the camshaft .
In case of a total power loss, each of Chernobyl's reactors had three backup diesel generators, but they took 60–75 seconds to reach full load and generate the 5.5 MW needed to run one main pump. [ 18 ] : 15 Special counterweights on each pump provided coolant via inertia to bridge the gap to generator startup.
At 13:00 on the 14th, the RCIC pump for unit 2 failed after 68 hours of continuous operation. With no way to vent the PCV, in response, a plan was devised to delay containment failure by venting the reactor vessel into the PCV using the SRVs to allow for seawater injection into the reactor vessel. [8]: 42–43
The R10 TDI employed many new and innovative features, the most notable being the twin-turbocharged direct injection diesel engine. It was first raced in the 2006 12 Hours of Sebring as a race-test in preparation for the 2006 24 Hours of Le Mans , which it later went on to win.
