This ensures fuel
efficiency and performance
under all conditions, even as the compression
ratio and engine speeds change.
Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional heads Lightweight titanium intake valves and machined connecting rods for reduced reciprocating mass High 10.0:1 compression
ratio — for a forced - induction engine — enhances performance and
efficiency and is enabled by direct injection Forged aluminum pistons with unique, stronger structure to ensure strength
under high cylinder pressures Stainless steel exhaust headers and an aluminum balancer that are lighter than their LT1 counterparts Standard dry - sump oiling system with larger cooler capacity than Z51; used with dual - pressure - control oil pump.
Essentially, SFI D - 4 integrates two types of fuel injection: A direct - type high - pressure fuel injection system, which provides a cooling effect in the cylinders and enables the high compression
ratio (11.8:1) employed to extract maximum energy from the fuel; and a set of low - pressure port fuel injectors that help produce a precise burn to optimize power and
efficiency under light - and medium - load conditions.
Compression
ratios range for 8.0:1 to 14.0:1, which varies
under driving conditions to optimize both power and
efficiency.
D - 4S integrates two types of fuel injection: a direct - type high - pressure fuel injection system, which provides a cooling effect in the cylinders and enables the high compression
ratio (11.8:1) employed to extract maximum energy from the fuel; and a set of low - pressure port fuel injectors that help produce a precise burn to optimise power and
efficiency under light and medium - load conditions.
