Mitsubishi unveils new 1.8-liter gasoline engine image

Mitsubishi Motors has unveiled a new compact 1.8-liter gasoline engine incorporating a new version of the company’s MIVEC* variable valve timing system and the latest version of the company’s Auto Stop & Go (AS&G) idle-stop technology.

Codenamed 4J10, this new engine will power the Japan-market RVR (ASX or Outlander Sport in some markets) compact SUV, the Galant Fortis sports sedan (Lancer or Lancer EX in some markets), and Galant Fortis Sportback (Lancer Sportback in some markets) 5-door sports hatchback.

According to the company, the combination of both technologies provides quick engine restart and initial acceleration performance that feels no different from a car without Auto Stop & Go .
In addition, fuel efficiency is improved because the new MIVEC engine allows the engine to restart using less intake air and fuel by keeping a low valve lift at engine restart.

The current engine for all variants of the local market ASX and Lancer EX is the 4B11, a 2.0-liter engine capable of 150 and 155 horsepower, respectively.
