Features And Types Of Holset Turbocharged Engines

In a conventional diesel engine, the air entering it is compressed before the fuel is injected. A turbocharger compresses the increased amount of air that comes to the engine. As a result, more amount of fuel is injected, resulting in more mechanical power.

Holset is a well-known name in medium to heavy-duty turbocharged diesel engine technology. The main advantages of holset turbo engines are improved fuel consumption, reliability, density, and reduced emission. Holset turbocharger technology is 60 years old and is currently manufactured by Cummins Engine Company Inc. Holset range of turbocharged engines is widely known for its high performance, superior quality, and proper safety standards. 

History Of Holset Turbo:

Buchi first invented the turbocharged diesel engine in 1915. In the year of 1925, the first application of turbocharger in the form of two 2000 hp turbocharged diesel engines, which were used in two ships in Germany. Turbocharged engines were first manufactured on a large scale by Cummins in the 1950s. Volvo also produced its first turbocharged diesel truck engine during the same period. Holset adopted turbocharger technology in the 1950s and quickly became a significant manufacturer of turbochargers. The holset turbo became famous due to its high durability and superior design. In the year 1973, Cummins Engine Company Inc. took over the ownership of Holset turbo.

Holset is known as Cummins Turbo Technologies since 2006 and is a daughter company of Cummins Inc., the largest manufacturer of diesel engines in the world. The range of holset turbo chargers manufactured by Cummins has the largest share in the heavy-duty and commercial applications. Holset turbochargers are sold through Cummins’ 170 distributors present in 70 countries. 

Types of Holset turbochargers 

There are various types of turbochargers available and you can find different types of Holset turbochargers manufactured by Cummins here:

Fixed Geometry: Fixed Geometry holset turbo is the pioneering turbocharger technology of Holset. This type of turbocharger increases the engine power by funneling all the exhaust gases into the turbine. This turbocharger technology has been around for the last 60 years, but Cummins has continuously improved its performance and reliability. Fuel economy is the primary advantage of fixed geometry turbochargers. Fixed geometry turbochargers come in frame sizes of 150, 200, 300, 500, 600, 800, 900, and 1000. They are designed for light to heavy-duty applications.

Variable Geometry: Variable Geometry holset turbo technology was first introduced in 1998 for diesel engines of commercial vehicles. Holset VGT enables high boost pressure at low engine speeds. It is achieved due to a wide range of flow caused by a patented sliding nozzle ring. VGT turbocharger has less moving parts because the vanes slide axially. As a result, your engine cannot get affected by wear and tear. New research and development are being conducted by Cummins to increase the fuel efficiency of VGT turbocharger and reduce the operating costs. VGT turbocharger comes in frame sizes of 200, 300, 400, and 500. VGT turbochargers are manufactured for light-duty, medium-duty, and heavy-duty applications.

Wastegate: Wastegate holset turbo charger uses optimized wastegate. Wastegate controls the release of excess exhaust gases concerning amount and timing. The optimized wastegate of the turbocharger prevents over boost of the engine and also prevents over-speeding of the turbocharger. Frame sizes of electrical types are 200 and 500, while that of pneumatic varieties is 150, 200, 250, 300, 450, 500, and 600.
