| + | In 1982, Mitsubishi developed what has been hailed as the world's first engine with cylinder deactivation technology with the 4G12 Modulated Displacement (MD). Contrary to popular belief however, Mitsubishi was the second car maker to bring the technology to market with Cadillac's L62 being released to the market for a year in 1981. | ||
| + | |||
| + | Mitsubishi's MD deactivated cylinders 1 and 4 under light load conditions in an effort to reduce fuel consumption. It achieved this by use of an Electronic Control Unit which detects whether the engine needs to be in 2 or 4 cylinder mode, an oil pump, an oil control valve which contains a three port solenoid to control deactivation devices on the valves of cylinders 1 and 4. | ||
