Mitsubishi Motors has been busy working on its next generation MIVEC engine for which it developed two new fuel saving technologies. The company’s 1.8-litre gasoline engine known as the 4J10 has received a new version of the MIVEC variable valve timing system and also the latest version of their Auto Stop & Go idle stop technology.
The first model to receive the new 1.8 liter MIVEC engine in combination with Auto Stop & Go will be the on the Japan market RVR (known as the ASX or the Outlander Sport on certain markets), on which fuel consumption figures will improve by 12 percent.
The new 1.8-litre is an engine featuring 4-inline cylinders and 16-valve on which the MIVEC system controlling the intake valve lift, the opening duration and timing has been tweaked in order to improve combustion stability and reduce piston friction without compromising performance.
This mean the engine continues to have a maximum output of 139 PS (102 kW) at 6,000 rpm and 172 Nm of torque at 4,200 rpm.
As for the new Auto Stop & Go this idle-stop mechanism has been developed for models with continuously variable transmissions (CVT) and it shuts off the engine when the car is stopped in order to minimize consumption.
