This led directly to the production of the 6.9-liter IDI diesel. The engine is developed as a low cost, light weight diesel that fit where a V8 gas engine would, to try to convert their gas engine customers to diesel and to sell to Ford for use in F-Series light duty trucks and E-Series/Econoline vans.
Second big problem: GM's cost-cutters decided not to fit a water separator. Unlike gasoline, diesel fuel is subject to water condensation – hence the need for a water separator. Without one, water in the fuel becomes water in the engine, where it can rust either the cylinders or the complicated mechanical fuel injection pump.
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
That may be caused by weak or leaky injectors, fuel settings turned up too high or over fueling for the given rpms. Cold weather running or other causes that prevent the engine from reaching proper operating temperature can cause a buildup of fuel due to incomplete burn that can result in 'wet stacking'.
The Ford 400 engine was based on the 351 Cleveland but had a half-inch longer stroke than the 351 Cleveland. The 400 had "square" proportions, with a 4.0 in (102 mm) bore and stroke. Ford called the engine a "400" but in actuality it displaced 402.1 cu in (6.6 L; 6,590 cc). To accommodate the longer stroke, Ford engineers increased the block ...
The Ford Explorer was introduced in March 1990 as an early 1991 model to replace the Bronco II. As Ford sought to balance off-road capability with family use of the vehicle, [10] the Explorer underwent extensive design changes from its predecessor, though still retaining commonality with the Ranger pickup truck.
