The B1928 Code explains the problem of the car engine. While fuel economy was amplified, acceleration was extremely cooperated, and the loss of engine vacuum led to a hazardous loss of braking support when the B1928 code system was in 4-cylinder mode. In addition to these matters, while the company planned a hydraulically measured system that could be substituted from within the car, the version they realized had to be manually different in the engine section using hand tools. The dictionary meaning of the code is not very helpful. You have nothing to with the basic meaning with the car engine.
