The 351W (Windsor) made its debut in 1969; it is often confused with the Ford 351 Cleveland, a different engine of near identical displacement that also began production in 1969. The 351.9 cu in (5.8 L; 5,766 cc) Windsor featured a 1.3 in (32.5 mm) taller deck height than the 289/302, allowing a stroke of 3.5 in (88.9 mm).
The Q-code 351 "Cobra-Jet" (also called 351-CJ, 351-4V) was produced from May 1971 through the 1974 model year. It was a lower-compression design that used open-chamber 4V heads. [ 5 ] The open-chamber heads exhibited superior emissions characteristics and were used to meet the more stringent emissions standards for 1972 and beyond. [ 1 ]
This means that the generally inferior flow of a reverse-flow head is less of a disadvantage. In the early days of turbo charging a reverse-flow head allowed the compressor outlet of a turbocharger to blow directly into the inlet manifold with either a blow-through or draw-through carburettor and no intercooler. This allowed the use of shorter ...
Ford 351 may refer to: Ford 351 Windsor (351W), an engine part of the Ford 90 degree V family; Ford 351 Cleveland (351C), an engine part of the Ford 335 family;
Uniflow scavenging is a design in which the fresh intake charge and exhaust gases flow in the same direction. This requires that the intake and exhaust ports be at opposite ends of the cylinder. As used by some two-stroke engines, the fresh charge enters through piston-controlled ports near the bottom of the cylinder and flows upward, pushing ...
A crossflow head gives better performance than a Reverse-flow cylinder head (though not as good as a uniflow), but the popular explanation put forward for this — that the gases do not have to change direction and hence are moved into and out of the cylinder more efficiently — is a simplification since there is no continuous flow because of valve opening and closing.
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Intake air throttling changes the amount of air sucked into the engine, which means that if a stoichiometric air-fuel mixture is desired, the amount of injected fuel has to be changed along with the intake air throttling. To do so, manifold injection systems have at least one way to measure the amount of air that is currently being sucked into ...
