If you have a lemon, make lemonade." Rather than complain about all the newfangled computer/smog technology, wise hot rodders are finding that they can adapt much of it to make their cars run faster.

High bandwidth control of the air-fuel ratio is necessary in order to minimize the exhaust emissions of sparkignition engines with three-way catalytic converters. A new approach is to implement a ...

For any engine to reach its maximum potential, the fuel must burn efficiently. Running rich or lean is not good for performance, and in extreme cases it can be catastrophic. A rich engine is likely to ...

This is a preview. Log in through your library . Abstract The method for measuring air-fuel ratio is generally based on analysis of the exhaust gas components and its calculations. A new instrument ...

A mass air flow sensor is one of the numerous tiny widgets and gewgaws that make up a modern automobile's electronic fuel injection system. In the MAF's case, it tells the car's computer how much air ...
