The Toyota B engine family was a series of inline-4 diesel engines.

Toyota also had a 3.4 L (3389 cc) inline-6 gasoline engine from 1937 to 1947 that was also called the B engine. The earlier engine was used in early Toyota cars and trucks and in the first version of the Land Cruiser when it was known as the BJ Jeep. The later engine was used in later versions of the Land Cruiser. The two engines are unrelated and were not made at the same time.

Toyota made 5 generations of the B family engines, each one identified with a number before the B letter. Also, Toyota uses a series of letters to identify technical improvements to their engines:

- The number 1 (one) before the number of the engine model means that the engine uses direct injection, otherwise, indirect injection

- The F letter after the B letter means that the engine is multivalvular. Since the B family are inline-4's, that means that the engine uses 16 valves.

- The T letter, means that the engine is turbocharged

- The E letter, means that the engine is electronically controlled engine control unit (ECU)

For example, the 15B-FTE Engine is the fifth generation of the B engines, comes with 16 valves, is turbocharged and uses an ECU.
