An intake is an air intake for an engine. Because the modern internal combustion engine is in essence a powerful air pump, like the exhaust system on an engine, the intake must be carefully engineered and tuned to provide the greatest efficiency and power. An ideal intake system should increase the velocity of the air until it travels in to the combustion chamber, while minimizing turbulence and restriction of flow. Cars with turbo chargers or superchargers which provide a pressurized intake system, usually have extensive tweaking of the intake system to improve performance dramatically. An engine is something that produces some effect from a given input. ... A colorized automobile engine The internal combustion engine is a heat engine in which combustion occurs in a confined space called a combustion chamber. ... Manual pump used to obtain water A pump is a mechanical device used to move liquids or gases. ... The exhaust system refers to the mechanism which conveys the burnt gases from an internal combustion engine and typically includes a collection of pipes. ... // Mechanical power In physics, power (symbol: P) is the amount of work W done per unit of time t. ... A combustion chamber is part of an engine in which fuel is burned. ... In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by semi-random, stochastic property changes. ... In terms of internal-combustion, most often Turbo is short for turbine supercharger. ... A supercharger (also known as a blower, a positive displacement pump or a centrifugal pumper) is a gas compressor used to pump air into the cylinders of an internal combustion engine. ...

A modern air intake system should have three main parts, an air filter, mass flow sensor, and throttle body. Many cars today now include a silencer to minimize the noise entering the cabin. Silencers impede air flow and create turbulence which reduce total power, so many performance enthusiasts often remove them. An air filter is a device which removes solid particles, such as dust, pollen, mold, and bacteria from air. ... A mass flow sensor responds to the amount of material flowing through a chamber containing the sensor. ... Fuel injection is a technology used in internal combustion engines to mix the fuel with air prior to combustion. ... The word silencer can mean:- A noise-suppressor on the end of a guns barrel. ...

Production cars have specific length air intakes to cause the air to vibrate and buffett at a specific frequency to assist air flow in to the combustion chamber. Aftermarket companies for cars have introduced larger throttle bodies and air filters to decrease restriction of flow at the cost of changing the harmonics of the air intake for a small net increase in power or torque. In physics, torque can be thought of informally as rotational force. Torque is measured in units of newton metres, and its symbol is Ï„. The concept of Torque, also called moment or couple, originated with the work of Archimedes on levers. ...

BMW is unusual in that it's M line of performance cars have one throttle body per cylinder, as opposed to one throttle body for four, six or even eight cylinders for regular production cars. This is done to increase flow characteristics and improve throttle response. BMW AG (an abbreviation for Bayerische Motoren Werke AG, or in English, Bavarian Motor Works), is a German company and manufacturer of automobiles and motorcycles. ...

Porsche in the 1980s designed an intake system for their cars that changed the length of the intake system by alternating between a longer and shorter set of tubing using a butterfly valve, creating a small amount of positive pressure which increased overall performance of the engine. Porsche (), (pronounced porsh-uh) is a German manufacturer of sports cars, founded in 1931 by Ferdinand Porsche, the engineer who created the first Volkswagen. ... The 1980s, in its most obvious sense, was the decade between 1980 and 1989. ... A Butterfly valve is a type of flow control device, used to make a fluid start or stop flowing through a section of pipe. ...
