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-fours, that means that the engine uses 16 valves. - The T letter, means that the engine is

turbocharged In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to pro ...
