The EF is an automotive engine made by Subaru, introduced in 1984 for the Subaru Justy. It is a water-cooled, straight-three, four-stroke engine with a belt-driven single overhead camshaft, and a chain-driven balance shaft. It has an alloy cylinder head and a closed deck iron engine block with a bore spacing of 86.0 mm (3.39 in). The two-cylinder EK23 engine is closely related to the EF series, sharing the same bore spacing and overall design. [1] The export market 665 cc EK42 motor even shares the bore and stroke of the EF10.

The Y-block engine is a family of overhead valve V8 automobile engines produced by Ford Motor Company. The engine is well known and named for its deep skirting, which causes the engine block to resemble a Y. It was introduced in 1954 as a more modern replacement for the outdated side-valved Ford Flathead V8 and was used in a variety of Ford vehicles through 1964.

Chrysler B engine Motor vehicle engine

The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi" due to their hemispherical shaped combustion chambers.

Honda B engine Former Japanese automobile engines

The B-series are a family of inline four-cylinder DOHC automotive engines introduced by Honda in 1988. Sold concurrently with the D-series which were primarily SOHC engines designed for more economical applications, the B-series were a performance option featuring dual overhead cams along with the first application of Honda's VTEC system. To identify a Honda B-series engine, the letter B is normally followed by two numbers to designate the displacement of the engine, another letter, and in US-spec engines, another number. The Japanese spec-engines are normally designated with a four character alphanumeric designation. The B-series, the B20B variant in particular, is not to be confused with the earlier Honda B20A engine introduced in 1985 and primarily available in the Prelude and Accord-derived vehicles from 1985 to 1991. While sharing some design elements and both being multivalve Honda four-cylinders, the B-series and B20A differ substantially in architecture, enough to be considered distinct engine families.
