Diesel Engine Technology: Commonrail & Variable Geometry Turbocharger

For lovers of diesel engines, there is an interesting technology that has developed from a typical engine-powered qualified. Performance support assistive technologies used in diesel fuel injection system and Variable Geometry Turbocharger Commonrail.

So what is meant by these two diesel technology.

Commonrail

The system utilizes a high pressure fuel pump and a chamber or cylinder engine rail per line. The maximum injection pressure can reach 1600 bar. The technology is the piezo injector commonrail supporters.

Injector voltage is passed it will change its crystalline structure, as a result of geometric changes that are mechanically triggered by opening the injector needle. Piezo Injector makes use of the needle component of the weight is reduced. If you usually reaches around 16 grams, is now no more than 4 grams. This means that although the piezo injector is smaller, but very good for the quantity of fuel is sprayed into the cylinder chamber.

Variable Geometry Turbocharger

The device also called a booster turbocharged diesel engines that power most effectively. Induski dense air is exhaled from the snail's house, making fuel more optimal. This resulted in increased power and emissions can be suppressed.

However, the use of a turbocharger is not without drawbacks. Generally, turbochargers will begin work on a high RPM. This could lead to turbolag, the article is less a result of gusts of exhaust gas to spin the turbo meresonansi.

To reduce symptoms turbolag, now on the turbo has been added to the bar that the angle can be adjusted based on engine speed. turbo blade angle is set by an actuator. It works, when low RPM, the blades will form a certain angle so that it can rotate simply by blowing gently. during high-rev engine, the angle of the blades will shrink as the cover. why the blast had felt able to rotate the turbine blades at home.
