Corvette C7 Engine Part Two
2014 Corvette C7 engine. Photos are of the LT1 engine without the Z52 dry sump oil system as evidenced by the oil filler cap and dipstick.
2014 Corvette C7 engine, installed and including the Z52 option (below); notice the lack of an oil filler cap and dipstick. Both items are part of the 11.5 quart dry sump tank which is separate from the engine but mounted in the engine compartment.
Direct injection fuel system rails.

Direct injection as installed in the block valley; rear view of LT1 engine. Note the fuel pump in the foreground. The fuel pressure it is responsible for is considerable; 2,175 psi as compared to less than 100 psi for standard fuel injection systems. The fuel pump is located in the block valley to keep the noise it produces under control - "Acoustic Encapsulation" is the technical term. The direct injectors flow 22.0 cc/s @ 10 MPa.

Engine block, bottom views, crankshaft removed. Below: Oil Jets View.
Above: Crankshaft view with piston cooling oil jets which are standard on all C6 and C7 Corvette engines. The oil spray reduces piston temperature, increasing output and long term durability. The extra layer of oil on the cylinder walls and wrist pins also dampens noise. For optimal efficiency, the oil jets are used only when they’re needed the most: at start-up, giving the cylinders extra lubrication enhancing the engine’s durability and at higher engine speeds when the engine load demands it.
