This block is one of three displacements, 302/327/350, that underwent a crankshaft bearing diameter transformation for 1968 when the rod-journal size was increased from the 2 in (50.8 mm) diameter small-journal to a 2.1 in (53.3 mm) large-journal and a main-journal size that was increased from 2.3 in (58.4 mm) to 2.45 in (62.2 mm).
Detroit Diesel 8V-71T as used in the U.S. M109 self-propelled howitzer. Bore and stroke are the same across all units, at 4 + 1 ⁄ 4 in × 5 in (108 mm × 127 mm). Inline models were famously "symmetrical," meaning that the blower, exhaust, water manifold, starter, and other components could be mounted on either side of the basic block to fit ...
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
Bore and stroke are the same across all units, at 3 + 7 ⁄ 8 in × 4 + 1 ⁄ 2 in (98 mm × 114 mm). These engines use a single camshaft per cylinder bank, paired with a balancing shaft for inline engines, or a second camshaft for the other cylinder bank in vee-block engines.
All Series 149 engines have overhead camshafts and the cylinder heads fit into the engine block; this is referred to as the "pothead" design. The blowers are also recessed into the block; this section of the block is called the "airbox". Above the blower is a thick piece of steel that covers the blower and seals the top section of the air box.
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.
When it was introduced in 1987, the Series 60 was the first heavy-duty diesel engine with fully integrated electronic controls. [2] Detroit Diesel prescribed overhaul intervals of 500,000 miles (800,000 km), then raised that to 750,000 miles (1,210,000 km) after more experience was gained with the new engine. [3]
The MDE is Opel's first all-aluminum diesel engine and offers a power density of 85 hp (63 kW) per liter 136 PS (100 kW; 134 hp) in its most powerful version. Maximum power and torque have been increased versus the previous-generation 1.7-liter engine, while fuel consumption has been reduced by up to 10 percent compared with a 2.0-liter CDTI ...
