To do this, Mazda has further developed several elementary technologies — a new
piston head design and super-high-pressure fuel injection system to support compression ignition, and a high - response air supply which can deliver larger amounts of air — and combined these with an in - cylinder sensor which serves to control the entire engine.

The traditional cylinder -
piston design used in engines means that only the
piston head itself produces motive force, as it is pushed up and down by the expansion of the burning fuel - and - air mixture.
If the surface of the stock
piston is smooth, it's probably a non-interference
design (valves and
piston head never occupy the same physical space) and the Wiseco
piston has to make the cuts into the
head to allow for sufficient clearances.

designed with other features that serve to optimize engine performance through forced air induction, including: Forged steel connecting rods, forged aluminum
pistons, Rotacast A3536T6 aluminum cylinder
heads with lightweight titanium intake valves and hardware, an aluminum balancer, a dry - sump oiling system, and stainless - steel exhaust headers for more rapid heat dissipation.
The engines also feature a new cylinder -
head design and a new, sculpted
piston to optimize the mixing of air and fuel in the engine and the burning of the mixture to create power.
The aluminum
pistons were redesigned; the nearly flat
design of the
piston heads is precisely tuned to the intake ports that were also redesigned.
These technologies support the all - new, advanced combustion system, which incorporates a new cylinder -
head design and a new, sculpted -
piston design that is an integral contributor to the high - compression, mixture motion parameters enabled by direct injection.
The MDX's evolved 3.7 L V - 6 uses a more rigid cylinder block, high - strength crankshaft, heavy - duty connecting rods, high compression - ratio
