What is Volvo turbo compound?
Volvo Trucks Makes Latest-Generation D13 Turbo Compound Engine Standard in VNL Models. The D13TC engine is equipped with Dynamic Torque which enables the driver to operate the truck in a more fuel-efficient manner by adjusting to the exact load without impacting performance. November 17, 2020.
How does a turbo compound engine work?
Like a turbocharger, the turbo-compound approach recovers waste-exhaust energy, but, instead of powering a compressor, the turbine wheel is connected to the crankshaft through a train of gears. The generator can also operate as a motor to preemptively spin the compressor to eliminate boost lag.
What is a compound turboprop?
A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines, the energy is instead sent to the output shaft to increase the total power delivered by the engine.
What is the importance of knowing the turbo compound engines?
For this reason, turbocompound introduction allows a significant efficiency improvement in a series hybrid vehicle, where the engine always works at high-load. The fuel economy of the proposed vehicle is compared with other hybrid and conventional vehicle configurations.
What is a D13 engine?
Volvo Penta D13 is an in-line 6-cylinder, 12.8-liter, diesel engine using a high-pressure unit injector system, overhead camshaft, and a twin-entry turbo using a water-cooled exhaust manifold. This contributes to world-class fuel efficiency and excellent operating economy, combined with very low emissions.
Who makes Volvo truck engines?
Volvo Trucks have built a number of engines, beginning in the late 1920s. In the 2010s, they have also begun using engines developed by Germany’s Deutz AG….D6B.
| Engine D6B | |
|---|---|
| Manufacturer | Volvo |
| Layout | |
| Displacement | 5.5 L |
| Cylinder bore | 98.425 mm |
What is a asymmetrical turbo?
An efficient way to simultaneously reduce the engine fuel consumption and the emissions (NOx) is an asymmetric twin-entry turbine turbocharging system. The asymmetric twin-entry turbine uses a volute that has two scrolls in the axial direction with different throat areas.
How does a compound engine work?
Compounding engines In the compound engine, high-pressure steam from the boiler first expands in a high-pressure (HP) cylinder and then enters one or more subsequent lower pressure (LP) cylinders. Pressure difference is less in each cylinder so there is less steam leakage at the piston and valves.
How much fuel does a turboprop use?
When researching an aircraft, you may find both statistics, or you may just find one….Fuel Burn Rates for Private Aircraft.
| Aircraft Category | Approximate Fuel Burn Range (Gal/hr) | Approximate Fuel Burn Range (lb/hr or pph) |
|---|---|---|
| Turboprop | 58 – 100 | 390 – 670 |
| Light Jet | 77 – 239 | 515 – 1,600 |
| Mid-Size Jet | 233 – 336 | 1,561 – 2,251 |
| Long-Range Jet | 358 – 672 | 2,399 – 4,500 |
Is a turbo prop safer than a jet?
Turboprop vs Jet Safety Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe. Because of the drag propellers cause, they actually allow the aircraft to stop much more quickly than a jet.
What is power recovery turbine?
Power recovery turbines (PRTs) are pumps that run in reverse used to energy from a process and improve overall system efficiency. A PRT is a single or multistage pump or turbine that is used in a process when a fluid is pressurized and must be reduced in pressure.
Is the Volvo D13 a good engine?
With that ideal balance between power and efficiency, Volvo D13 engines are a pleasure to drive. Trucks equipped with this Herculean powertrain are easily able to help you meet every demand of your business, making them ideal to rely on.
How does a Volvo FH powertrain work?
This is enabled through Turbo Compound technology, which utilises an extra turbine after the turbocharger to reuse excess energy from the exhausts. This energy is converted to torque directly on the crankshaft – producing a powerful and extremely fuel-efficient engine.
When does Turbo Compounding come out on Volvo Trucks?
Volvo Trucks’ new turbo compounding, available on our D13 engines beginning mid-2017. Turbo compounding can provide dramatic savings through fuel efficiency improvements of up to 6.5%.
What was the result of the Volvo FH fuel test?
In 2019, leading British truck magazine Commercial Motor subjected the Volvo FH with I-Save to its notorious Fuel Test to see if it could deliver on its promised fuel savings. The final result not only exceeded all expectations but also smashed the test’s previous record.
What does Volvo D13 turbo compound system do?
Fleets that run variable load applications, including tanker, bulk haul and flat-bed deliveries, can benefit from Volvo’s next-generation Turbo Compound system. The new D13 with Turbo Compounding captures and harnesses energy typically lost through the exhaust to recover lost horsepower and improve fuel economy.
