The cylinder head intake and exhaust ports and intake and exhaust manifolds are form optimized for far better volumetric effectiveness. Mitsubishi lowered the friction of your engine by which includes elastic grinding of the valve stems, adopting a substantial-performance shroud equipped plastic impeller during the drinking water pump and employing 0W-twenty minimal-viscosity oil. Mitsubishi elevated the combustion performance by optimizing the look in the cylinder head intake and exhaust ports, by incorporating the MIVEC system on the two intake and exhaust valves and through the use of injectors that provide an extremely micro droplet fuel spray.
The Mitsubishi 4B12 engine, renowned for its efficiency and reliability, has sadly been affected by a number of persistent concerns which have still left many owners discouraged and dissatisfied.
