Toyota R engine
The Toyota R family was a series of inline-four gasoline automobile engines. Designed for longitudinal placement in such vehicles as the Celica and Hilux and in production from 1953 through 1997, usage faded out as many of Toyota's mainstream models moved to front-wheel drive. Overhead cam (OHC) versions featured a chain-driven camshaft.
The 1.5 L (1,453 cc) R family was produced from 1953 through 1964, and was originally manufactured at the Toyota Honsha plant.
Bore and stroke was 77 mm × 78 mm (3.03 in × 3.07 in). In common with new engines of the time, it was made from cast iron (both the block and the head), water cooled, used a three bearing crank, 12V electrics and a side-mounted gear-driven camshaft controlling overhead valves via pushrods in a non-cross flow head (exhaust and inlet manifolds being on the same side of the engine). Induction was by a twin throat down-draft carburettor, the compression ratio was 8.0:1 and the total weight was 155 kg (342 lb). An LPG version, the R-LPG, was produced for the last two years.
The R engine was the Toyota engine used in the 1958 Toyota Crown, the first model to be exported to the United States. Road & Track was unimpressed with the engine on its introduction, noting that it idled quietly but was "not capable of very high revolutions per minute."
Applications:
The 1.5 L (1,490 cc) 2R family was produced from 1964 through 1971. It is a square engine, with bore and stroke of 78 mm (3.07 in).
Again, an LPG version, the 2R-LPG, was produced alongside the gasoline version. Production had been gradually transferred from the original Honsha plant to the new Toyota Kamigo plant in 1968.
