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 Navistar T444E is a diesel V8 engine manufactured by Navistar International Corporation. In its use in Ford Motor Company trucks, vans, and school buses, it is the first of the Power Stroke family of diesel engines. The T444E was manufactured from 1994 to 2003, replacing the 7.3L IDI V8 designed by International
Windward is upwind from the point of reference, i.e., towards the direction from which the wind is coming; leeward is downwind from the point of reference, i.e., along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side".
For 1987, a larger 7.3 L version of the IDI was introduced. [7] This engine features numerous improvements over the 6.9, with most of the changes located in the heads; the block received an increased bore and select-fit pistons, while the heads received an enlarged prechamber, enlarged valve stem shields, harder valves, and other minor upgrades.
Upwind, the rotor works as a wind turbine driving the wheels. Downwind, it works as a propeller, driven by the wheels. In both cases, power comes from the difference in velocity between the air mass and the ground, as received by the vehicle's rotor or wheels. [17] Relative to the vehicle, both the air and the ground are passing backwards.
Sailing downwind, the apparent wind decreases the more the ship speeds up and at exactly the true wind speed, would drop to zero, so that the wind turbine can generate no power and also no thrust if used in the autogyro mode. Therefor windmill ships are limited to less than wind speed when travelling directly downwind, as with other sailing craft.
The power-recovery turbine sits underneath a two-stroke diesel engine. A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines , the energy is instead sent to the output shaft to increase ...
