ABSTRACT

The engines that are used now a days spot a constant compression ratio. It is economic for the compression ratio must decrease with the speed. But there is a practical difficulty for the engines to alter its compression ratio while in working. But there has been a break through, researchers have found out new ways by which the compression ratio can be altered. Thus comes a new breed of engines called the Variable Compression Ratio Engines. Volkswagen has come up with a production version too. In this type the h ....etc

There is disclosed an electronic control system for controlling a carburetor equipped with a slow system system solenoid valve and an enrichment system solenoid valve of different control ranges whose openings are electromagnetically controlled to control the air-fuel ratio of a Mixture supplied to internal combustion engine. The control system calculates, based on signals representative of the engine operating condition including the engine temperature, the duty of control of the main system solenoid valve slow according to the air-fuel ratio ....etc

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. ....etc
