Boost in automotive engineering is a positive manifoldpressure in cars with turbochargers or superchargers. Wikipedia does not have an article with this exact name. ... The manifold absolute pressure (MAP) sensor is an important sensor in modern internal combustion engines that use fuel injection. ... ... Left side of a Ford Cologne V6 engine, clearly showing a (rusty) cast iron exhaust manifold - three exhaust ports into one pipe. ... The use of water pressure - the Captain Cook Memorial Jet in Lake Burley Griffin, Canberra. ... Air foil bearing-supported turbocharger cutaway A turbocharger is an exhaust gas-driven compressor used to increase the power output of an internal-combustion engine by compressing air that is entering the engine thus increasing the amount of available oxygen. ... A supercharger (also known as a blower) is an air compressor used to force more air (and hence more oxygen) into the combustion chamber(s) of an internal combustion engine than can be achieved at ambient atmospheric pressure. ...
Boost is quantifiable as the pressure above atmospheric pressure that the turbocharger or supercharger is creating in the engine's inlet manifold, and is usually measured in bar or PSI (pounds per square inch). Diurnal (daily) rhythm of air pressure in northern Germany (black curve is air pressure) Atmospheric pressure is the pressure at any point in the Earths atmosphere. ... The bar (symbol bar) and the millibar (symbol mbar, also mb) are units of pressure. ... Psi has multiple meanings: Psi (letter) (Ψ, ψ) of the Greek alphabet Psi (Cyrillic) (Ѱ, ѱ), letter of the early Cyrillic alphabet, adopted from Greek Psi (instant messenger), the popular Jabber client program J/ψ particle, a subatomic particle Schrödinger equation in quantum mechanics, ψ Ψ in mathematics is the angle between the tangent and the...
Linking these car tuners to engineering is a rather easy connection to make, after all, these tuners are mechanics, but acknowledging the whole street racing scene as an integral part of automotiveengineering may prove a little unclear.
These street engineers, whether it be an individual mechanic who works on his car on the weekend, or a team of engineers hired by a big-name automotive manufacturer, all possess the knowledge and experience in the core engineering disciplines; physics, chemistry, and calculus.
Also, using knowledge of engineering principles, no one is to do anything to their car that may potentially harm him or someone around him, like turning up the boost to an insane level.
As for the hose that connects the solenoid to the engine parts, if you consult the Ford Parts manuals, the hose is serviced by a standard 7/32 vacuum hose which is more than able to handle the underhood temperatures--which don't reach 200 degrees F. in that area.
My experience has shown that when the outside air temperature and engine are cold, detonation is hardly noticeable, but when the engine warms up (specifically the piston tops, valves, spark plugs and combustion chamber surfaces), detonation is more pronounced which holds true to theory.
One of the prominent reasons is that, in proportion to the rise in boost, charging efficiency increases and provides higher indicated horsepower while the engine's mechanical losses remain almost the same, resulting in an improvement of brake thermal efficiency.
