Uses of Variable Turbocharger
Dodge Ram has won the hearts of many consumers by utilizing the beloved Cummins engine. For many years, this engine platform was used in dozens of applications. Boats, school buses, farm tractors, commercial and utility trucks commonly had Cummins engines. Late model designs have incorporated the larger 6.7 L Cummins platform that has many updated changes from its predecessor the 5.9 L. One of those updated changes is the use of a Variable Geometry turbocharger.
Turbochargers are designed to compress air and force it into the intake of the engine. The quantity of diesel fuel that can be burned is limited to the quantity of air available. Thus when a larger volume of air enters the cylinder, more fuel can be burned. The more fuel that is burned, the greater the output of power. The larger that a turbo is, the greater volume of air that it will move. However, the turbo spools from pressure and heat that come from the exhaust of the engine. With the exhaust pressure being a given quantity, this means that if too large of a turbo is placed on that engine, then that turbo will not be able to spool to generate any beneficial boost. Smaller turbos are easier to spool than larger ones because the compressor and turbine wheel are smaller, lighter and easier to spin.
On the surface it may seem like a smaller turbo would be best choice because of its quick easy spool up. However another obstacle comes into play when too small of a turbocharger is chosen, that obstacle is heat and over spinning of the turbocharger. Excessive heat and over spinning the turbocharger can critically damage the turbo, the engine and other vital components.
To help overcome these obstacles, engineers have designed the Variable Geometry Turbo (VGT). A VGT designed turbo has vanes on the turbine side that collapse and effectively reduce the size of the turbine housing. This reduction in size, increases the pressure going through the turbine housing. This increase in pressure allows for the spooling of a larger turbine and compressor wheel. As the turbo RPM and engine RPM increase, The actuator (an electronic device that controls the vanes on the turbine side) causes the vanes to open and reduces the pressure of the exhaust gas flowing through the turbine side. This design allows for a relatively large turbo to spool easier initially while helping to prevent overheating and over spinning.
These turbos are fantastic in design and function, however, the more complex a component gets, and the more likely it is that some component within itself will fail. Like any other engine component, eventually a VGT turbo or its actuator will wear out and need to be serviced, cleaned or replaced completely. When that time comes, Source Automotive has the perfect solution! Source Automotive has teamed up with High Tech Turbo to offer re-manufactured VGT turbos for 6.7 liter Dodge Diesel trucks equipped with the Cummins engine. The experts at Source Automotive can help you select the perfect sized turbo for your truck’s purpose. If your turbo needs repair, a new actuator or a complete overhaul we can help!
