Characteristics
??
The engines?s bore and stroke both measure 86.0 mm, which engineers refer to as square. According to Mitsubishi, the new cylinder dimensions contribute to a free-revving character (6,500 rpm redline, 8000 rpm final), linear power delivery and wide torque curve. Mitsubishi used a timing chain instead of a belt for better reliability, iridium spark plugs to lower emissions and to help extend major service intervals for lower cost of ownership. To reduce weight, Mitsubishi used a plastic cam cover and intake manifold and double-layer stainless steel exhaust manifold. The exhaust manifold has a rear location on the transverse engine, compared to the front location for the previous engine, yielding important benefits such as better emissions performance. To lower vibration, Mitsubishi used a 4-point inertial axis system with cylindrical hydraulic engine mounts on the left and right sides. A lightweight, high-rigidity squeeze-cast aluminium bracket on the right side mount (engine side) lowers engine noise under acceleration. A lightweight, high-rigidity steel plate bracket on the left side mount (transmission side) lowers gear noise. A custom-tuned insulator was developed for the front and rear mounts to help control both idle vibration and acceleration shoc....
