A camshaft with 301/313 degrees of advertised duration, 0.407-inch (10.3 mm) net valve lift, and 76 degrees of valve overlap was specified for actual production engines in lieu of the significantly more aggressive Ram Air IV-spec camshaft that had originally been planned for the engine (initially rated at 310 hp (231 kW) with that cam), but ...
GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine. GM used the Active Fuel Management technology on a range of engines including with the GM Small Block Gen IV engine family, first-generation GM EcoTec3 engine family, second-generation GM High-Feature V6 DOHC ...
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines.These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line.
All of these engines are 12-valve cam-in-block or overhead valve engines, except for the LQ1 which uses 24 valves driven by dual overhead cams. These engines vary in displacement between 2.8 and 3.4 litres (2,837 and 3,350 cc) and have a cast-iron block and either cast-iron or aluminum heads.
Though the pre-3800 rear-wheel drive (RWD) V6 uses the Buick, Oldsmobile, Pontiac (BOP) bellhousing pattern, an oddity of both the front-wheel drive (FWD) and RWD 3800 V6 is that although it is a 90° V6, it uses the GM 60° V6 bell housing (Metric Pattern). For use in the FWD applications, the bellhousings on the FWD transmissions are altered ...
In 1935, Pontiac re-introduced their six-cylinder engine, as a 208 cu in (3.4 L) straight-6. The 208 was produced in 1935 and 1936. It was a side-valve design with a timing chain, as was popular at the time. This engine featured a conventional one piece cylinder head, and the distributor was moved to the side of the block.
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.
The crossflow cylinder heads are made from a cast iron alloy, and the five-bearing camshaft is constructed from a case-hardened steel alloy. Although the engine is often described as a twinned Volvo B18 four-cylinder, only some components of the valve train are interchangeable between the two engines.
