Embodiment Construction
[0112] Some embodiments may include such as figure 1 A motor vehicle system 100 is shown, which includes an internal combustion engine (ICE) 100 (in this example a diesel engine), a transmission (in figure 1 In the example shown in FIG. The hybrid powertrain system has at least figure 1 DC electric drive axle in the example, rear axle 520 .
[0113] Such as figure 2 and image 3 As shown, the ICE 110 has an engine block 120 defining at least one cylinder 125 having a piston 140 coupled to rotate a crankshaft 145 . Cylinder head 130 cooperates with piston 140 to define combustion chamber 150 .
[0114] A fuel and air mixture (not shown) is placed in combustion chamber 150 and ignited, resulting in thermally expanding exhaust gases that cause reciprocating motion of piston 140 . Fuel is provided by at least one fuel injector 160 and air passes through at least one air intake 210 . Fuel is provided to fuel injector 160 at high pressure from fuel rail 170 fluidly connected...
