1. An improved V12 reciprocating internal combustion engine having an Electronic Fuel Injection (EFI) system, a Distributorless Ignition System (DIS) and a Powertrain Control Module (PCM) having fuel injector pulse and ignition maps to control fuel and fire the cylinders of said engine by said EFI and DIS systems, comprising in operative combination:

  • a. twelve cylinders disposed as a pair of multi-cylinder, cylinder banks in an engine block of 90°

    V12 geometry, each bank having six cylinders and terminating at the upper ends of said cylinders in a head, said block and said heads having a first and a second end;

    b. each said cylinder contains a movable piston connected to a common crankshaft via a connecting rod, said crankshaft is mounted in said V12 engine block to rotate in seven bearings, at least one bearing being disposed adjacent each end of said block, and five bearings being distributed intermediate said end bearings and between connections of said connection rods to said crankshaft;

    c. said PCM containing a microprocessor and a database structure comprising injector fueling maps and firing maps; and

    d. said PCM controlling said engine for Progressive Single/Pair fueling and firing, so that in 720°

    of rotation of said crankshaft, all 12 cylinders are fueled and fired, said PCM controlling said firing with respect to the location of pistons in said cylinders to result in an even fired 90°

    V12 internal combustion engine having more torque and power output than an odd fired 90°

    V12 internal combustion engine of the same displacement.
