Ultra-running engine on the infrastructure point of view, large displacement V8 or V12 engine still can not escape from the big piston bore, short stroke characteristics, this design provides sharp throttle response, engine speed is also rising very fast, although it will produce higher peak torque speed, resulting in low speed unresponsive phenomenon, Skyline crankshaft but these shortcomings with the latest computer technology and electronic throttle control, variable valve timing control system, or even a direct injection fuel supply, show more high efficiency linear power output.
In the engine hardware itself and materials used, apart from lightweight aluminum alloy cylinder block, magnesium alloy, or even a lightweight titanium alloy such special metal materials and more extensive use of the level. The weight of the internal parts of the engine in order to minimize and retain high rigidity, crankshaft, connecting rods and forged pistons almost have to use products, and the intake and exhaust tract, bearing also are polished and smooth process, or even appear Mg-Al alloy cylinder head production,RB26 crankshaft titanium Valve, combined with the special treatment of the inner cylinder wall (coated with nickel silicon carbide) to replace the traditional metal cylinder, the engine can significantly reduce body weight and body weight balance with to help.
