The Mitsubishi KE engine is a range of engines produced by Mitsubishi Motors during the 1960s and early 1970s. They were extensively used in the various Colt-branded vehicles the company produced from 1963.

The engines were overhead valve iron-blocks, for gasoline and diesel use. The first digit after the KE denotes the number of cylinders, straight-4s becoming KE4 and six-cylinder versions such as the single overhead camshaft 2.0 L straight-6 which was developed in 1964 for the new Mitsubishi Debonair flagship sedan, receiving the KE6 prefix. The last digit is simply a serial, denoting which number engine it is. Some of these engines, such as the two-liter KE42, were further developed into overhead-cam engines and were named Astron.
As a large scale manufacturer, Mitsubishi had a wealth of experience building engines, both gasoline and diesel, in V and straight engine block configurations during the war. One of their many examples was the air-cooled A6120VDe air-cooled inline 6-cylinder 14.4 L diesel and the SA12200VD air-cooled V-12 diesel (21.7 litres).

KE42
editThe petrol-powered KE42 was first used in the Mitsubishi Jupiter Junior truck beginning in 1963. In 1973, the KE42 was upgraded to meet new emissions regulations and received the MCA (Mitsubishi Clean Air) name to reflect this. Power also increased by 5 hp (4 kW).[3] This engine was developed into an overhead-cam unit, called the Astron 4G52.

KE64
editDerived from the four-cylinder KE43 engine, the bore of the KE64 was increased by 8 mm, giving it an overall displacement of 1,991 cc (2.0 L). The valve layout is similar to Opel's cam-in-head design; the camshaft sits higher than in a regular pushrod engine, alongside the top-dead-center of the pistons, but not above the valves as in an overhead-cam engine.[6] The valves are actuated by short tappets rather than pushrods, allowing for a low engine with some of the more free-revving, smoother characteristics of an SOHC engine.

| Bore x stroke | 80 mm × 66 mm (3.15 in × 2.60 in) |
