The MOST AMAZING Features of the GE Jenbacher 6000HP V12 Engine

Summary

In this video from Rasbury Productions, John introduces the Yena 612, a powerful V12 gas engine designed for high-performance applications. He walks viewers through the engine's components, including its air and gas intake systems, turbochargers, and heat exchangers. The engine is capable of generating 2 MW of electricity at 60% load, and John demonstrates how the CHP controller monitors engine parameters such as ignition voltage, exhaust temperature, and knock levels. The video also touches on the engine's efficient use of thermal energy and its integration into building systems like underfloor heating and low-temperature radiators.

Takeaways

• 😀 The video features a detailed overview of the Yena 612 gas reciprocating engine.
• 😀 The Yena 612 engine is made in Austria and has a V12 configuration with a 190mm bore and 220mm stroke per cylinder.
• 😀 Each cylinder of the Yena 612 engine has a displacement of about 625 liters.
• 😀 The engine uses HT leads and spark plugs, which are characteristic of gas engines but not diesel engines.
• 😀 The gas induction system includes a centrifugal gas booster that boosts low-pressure gas to the engine's working pressure.

Q & A

What is the Yena 612 engine's configuration?

The Yena 612 engine is a V12, 60-degree configuration, designed for industrial applications.

What are the key specifications of the Yena 612 engine's cylinders?

Each cylinder of the Yena 612 engine has a 190mm bore and a 220mm stroke, giving a displacement of approximately 625L per cylinder.

How does the Yena 612 engine differ from a diesel engine?

The Yena 612 engine is a gas reciprocating engine, as opposed to a diesel engine. Notably, it uses spark plugs and HT leads, which are absent in diesel engines.

What is the purpose of the centrifugal gas booster in the Yena 612 engine?

The centrifugal gas booster increases the pressure of the incoming low-pressure gas (20 mbar) to the working pressure required for the engine.

How is the air and gas mixture handled in the Yena 612 engine?

The air and gas mixture is created by blending gas with fresh air after it passes through the air filters and gas intake system before reaching the turbochargers.

What cooling system does the Yena 612 engine use?

The Yena 612 engine uses a water-to-water heat exchanger system to remove heat, transferring it from the engine to the building interface plates.

What is the role of the 'charge air cooler' in the Yena 612 engine?

The charge air cooler cools the pressurized air after it passes through the turbochargers, which helps improve engine performance and efficiency.

What is the engine's electrical output, and how does it utilize thermal energy?

The Yena 612 engine generates about 2.0 MW of electrical output, with a similar amount of thermal energy, which is utilized for building applications like low-temperature heating and underfloor heating.

How does the Yena 612 engine monitor and regulate its performance?

The engine uses a CHP controller, which displays various parameters like voltage, current, power factor, exhaust temperature, ignition voltage, and knock levels to help monitor and regulate engine performance.

What is the purpose of the lubrication system in the Yena 612 engine?

The Yena 612 engine has a lubrication system that uses transfer pumps to move oil from a bulk storage location to the engine, ensuring that fresh oil is pumped into the engine after a change to maintain performance.
