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.
The L3A is the direct-injection 1.5 L naturally-aspirated variant of the SGE used in the second-generation Chevrolet Volt, with a 74 mm × 86.6 mm (2.91 in × 3.41 in) bore and stroke for a total capacity of 1,490 cc (1.5 L). The compression ratio is 12.5:1 and the engine can run on regular unleaded-grade gasoline.
Along with the increased bore spacing, the new 3.6 L DI V6 has larger bores than before, growing from 94 mm (3.701 in) to 95 mm (3.740 in) with the same 85.8 mm (3.378 in) stroke as the 3.0L LGW, for a displacement of 3.6 L (3,649 cc). Intake and exhaust valves are also increased in size along with other changes to the cylinder head. [21]
