Land Rover 2.25-litre petrol engine

The Land Rover 2.25-litre petrol engine was a new 2,286 cc four-cylinder unit introduced in 1958 for the Series II Land Rover, replacing the older inlet-over-exhaust petrol engines. Rover based it on the 2-litre diesel but changed the internal structure: it is a dry-liner design with a wider bore for better low-speed torque, and it could use the same machining line as the diesel, a commonality that lasted for decades. Castings came from Bean Industries of Sheffield using an in-house iron called Bilchrome. A five-bearing crankshaft was added in 1980. It was the most popular Land Rover engine until the mid-1980s, with a reputation for reliability and tolerance of poor fuel and oil, and Rover also fitted it to the P4 saloon as the Rover 80. It powered the Series II, Series III and the Ninety, One Ten and 127.
