The 4A9 is Mitsubishi's first four-cylinder engine family to adopt a high-pressure die-cast aluminum block. [ 1 ] [ 3 ] All engines developed within this family have aluminum cylinder block and head, four valves per cylinder , double overhead camshaft layouts, and MIVEC continuous variable valve timing (intake only).
In 2017, Mitsubishi launched a new series of gasoline inline-four engines called the 4K2 series. Originally consisting of three models, 4K20, 4K21 and 4K22, they are available in naturally aspirated as well as turbocharged versions. [10] This new design is based on the 4G6 shortblock, mated to a newly designed DOHC 16-valve head with MIVEC ...
MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1,597 cc naturally aspirated DOHC 16 valve straight-4. [2] At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control. [3] The first cars to use this were the Mitsubishi Mirage hatchback and the Mitsubishi Lancer sedan.
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres , making it one of the largest four-cylinder engines of its time.
Together with Mitsubishi's electric vehicle technology the new diesel engines are positioned as a core element in the Mitsubishi Motors Environment Initiative Program 2010 (EIP 2010) announced in July 2006. [3] [9] The 4N1 engine family is the world's first to feature a variable valve timing (intake side) system applied to passenger car diesel ...
