A mass airflow sensor is used to determine the mass of air entering the engine. The air mass information is necessary to calculate and deliver the correct fuel mass to the engine. Air is a gas, and its density changes as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the vehicle's operating environment, and is an ideal application for a mass sensor. (See stoichiometric, ideal gas law, and density.)

There are two common types of mass airflow sensors in usage on gasoline engines. The ....etc

Internal combustion engine
The internal combustion engine is an engine in which the combustion of a fuel (generally, fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. The expansion of high temperature and pressure gases produced by the combustion applies force to a movable component of the engine(piston, turbine blade etc.) moves it over a distance, generates useful mechanical energy.

The major advantages of a GDI engine are increased fuel efficiency and hi ....etc

ABSTRACT
Study of new and cost effective finishing processes has alwaysbeen an area of keen interest to overcome the difficulties ofexisting finishing process. Magnetic Abrasive Finishing(MAF) is a process in which a mixture of non-ferromagneticabrasives and ferromagnetic iron particles is used to dofinishing operation with the aid of magnetic force. The ironparticles in the mixture are magnetically energized using amagnetic field. The iron particles form a lightly rigid matrixin which the abrasives are trapped. This ....etc

A MAP sensor (manifold absolute pressure) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous pressure information to the engine's electronic control unit (ECU). This is necessary to calculate air density and determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow. (See stoichiometry.)

An engine control system that uses manifold absolute p ....etc

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc
