Product: Turbocharger Systems

As the largest manufacturer of general aviation turbocharging systems, Hartzell Engine Technologies supplies all of the major engine OEMs. Originally designed by Honeywell/Garrett and Rajay, we’ve invested in engineering development and software tools to create superior, proprietary system designs. While the turbocharger is the heart of a turbocharging system, the full system is comprised of multiple components working together. Each unit is inspected and certified, guaranteeing premium quality and serious boost.

To match aircraft turbochargers to engine specifications, we offer several size classes. Spanning the engine range from the Rotax 914 to the largest Continentals and Lycomings used in pressurized aircraft, our aircraft turbochargers are available for any size and performance requirements.

Turbochargers convert wasted energy, in the form of hot exhaust gases, into increased manifold pressure to increase the power available from the engine. The exhaust gases spin a turbine wheel at high speeds, commonly in excess of 100,000 rpm. The turbine wheel is connected to a compressor wheel that compresses the engine intake air, increasing its density

Functioning as the brain of the aircraft turbocharger system, various types of controllers sense upper deck and/or manifold pressure to maintain sea level horsepower at altitude, without over-speeding the turbocharger or over-boosting the aircraft's engine. It does this by controlling pressurized engine oil to hydraulically actuate the wastegate.

Wastegates, also referred to as Exhaust Bypass Valves, are necessary in many turbocharger systems to manage speed or compressor discharge pressure (boost) during certain conditions of a flight. Managed through a controller, the opening wastegate allows exhaust gas to bypasses the turbocharger, limiting speed and boost. At HET, we produce two categories of wastegate valves – a poppet style and a butterfly style.

Pressure Relief Valves, or overboost valves, act as a supplementary safety device in the aircraft turbocharger system. In systems with a pressure relief valve, the valve is set to open at a pressure slightly above the maximum upper deck pressure, should the controller or wastegate not adequately limit the boost pressure.

Scavenge Pumps are employed in aircraft turbocharging systems to efficiently return lubricating oil from the turbocharger center housing back to the engine crankcase.
