The Future of Koenigsegg
The Koenigsegg Jesko marks the end of an era for Koenigsegg, as it is set to be the last purely internal combustion engine-powered vehicle from the brand. In the future, Koenigsegg will focus on hybrid and electric cars, much like their previous model, the Regera. However, they are bidding farewell to traditional gasoline-based engines with a bang. The Jesko’s engine is the most powerful internal combustion engine ever created by Koenigsegg and holds the title of the most powerful homologated production internal combustion engine.
Fuel Flexibility and Power Optimization
The Koenigsegg Jesko exhibits remarkable fuel flexibility. It can operate on either gasoline or E85, a feature made possible by a flex fuel sensor that identifies the type of fuel being injected into the engine.
Performance Based on Fuel Type
| Fuel Type | Horsepower |
|---|---|
| Gasoline (91 or 95 octane) | 1280 |
| E85 | 1600 |
Key Points:
- Gasoline Performance: With gasoline (91 or 95 octane), the engine produces 1280 horsepower.
- E85 Performance: However, with E85, which has a higher octane rating, the Jesko unleashes its full potential, delivering a staggering 1600 horsepower.
- Advantages of E85: Running on E85 offers several advantages in terms of power optimization:
- Advanced Timing: The higher octane rating allows for advanced timing, meaning the spark plug can fire sooner without the risk of engine knock or damage. This optimal timing results in increased power output.
- Higher Boost Levels: The higher octane rating permits running higher boost levels, further enhancing performance.
- Air-Fuel Ratio Flexibility: The flexibility in air-fuel ratio selection enables the engine to find the perfect balance for maximum power production.
These features make the Koenigsegg Jesko a powerhouse, capable of delivering exceptional performance regardless of the fuel type used.
Triple Fuel Injection
The Koenigsegg Jesko’s engine features three fuel injectors per cylinder, making it the first production car to employ this setup. This triple-fuel injection system ensures there is an ample supply of fuel for the engine’s high demands.
Fuel Injection System
| Fuel Injectors per Cylinder | 3 |
|---|---|
| Primary Fuel Injectors Location | Mounted on a traditional fuel rail within the intake runner |
| Additional Injector Location | Added to the intake plenum before each runner |
Key Points:
- Ample Fuel Supply: The triple-fuel injection system ensures there is an ample supply of fuel for the engine’s high demands.
- Precise Fuel Delivery: The additional injector provides precise fuel delivery to each cylinder.
Tumble Flow Intake Ports
Koenigsegg redesigned the cylinder head to incorporate tumble flow intake ports to ensure optimal performance in all operating conditions and comply with emission regulations.
Key Points:
- Improved Efficiency: The new design channels the air over the top of the valve, creating a tumbling airflow pattern within the combustion chamber. This turbulent airflow enhances fuel mixing, resulting in improved efficiency, especially at low RPM and low load conditions.
- Aid in Cold Starts: The tumble flow intake ports aid in cold starts by promoting better fuel and air mixing before reaching the engine.
Flat Plane Crankshaft
The Koenigsegg Jesko’s engine has switched from a cross-plane crankshaft to a flat-plane crankshaft, offering several advantages.
Key Points:
- Lighter Crankshaft: With a flat-plane crankshaft, the crankpins are rotated 180 degrees apart, resulting in a lighter crankshaft overall.
- Mitigating Vibrations: While this setup may introduce more vibrations, Koenigsegg mitigates this by utilizing active engine mounts, compensating for any potential driver discomfort.
- Higher Rev: The flat-plane crankshaft enables the Jesko’s engine to rev higher, increasing the redline from 8250 to 8500 rpm.
Unique Turbocharging System
The Koenigsegg Jesko, with an engine producing over 1600 horsepower, requires a robust turbocharging system.
Turbocharging System Details
| Engine Horsepower | Over 1600 |
|---|---|
| Turbos per Cylinder Bank | 2 |
| Air Compressor | Electric |
| Air Storage | Carbon Fiber Tank |
Key Points:
- Turbo Setup: The engine features two turbos per cylinder bank to deliver the necessary boost. However, this setup presents a challenge of high boost thresholds and turbo lag.
- Innovative Solution: To overcome this, Koenigsegg employs an innovative solution inspired by Volvo’s diesel engine technology. The Jesko incorporates an electric air compressor that pressurizes air and stores it in a carbon fiber tank.
- Eliminating Turbo Lag: When the engine needs instant power at low RPM, the compressed air is released into the exhaust, spooling up the turbochargers quickly and eliminating turbo lag.
- Improved Throttle Response: This system not only improves throttle response but also aids in cold starts by injecting air into the exhaust, helping to heat up the catalytic converter faster.
Pressure Sensors for Optimal Performance
Koenigsegg takes engine performance optimization to the next level by implementing pressure sensors in the Jesko.
Pressure Sensor Details
| First Production Vehicle with Pressure Sensors | Jesko |
|---|---|
| Pressure Measurement | Inside the cylinder during the power stroke |
| Data Usage | Fed to the engine control unit (ECU) for spark timing adjustment |
Key Points:
- Pressure Sensors: The Jesko is the first production vehicle to feature pressure sensors, which measure the pressure inside the cylinder during the power stroke.
- Optimal Peak Pressure Timing: This data is fed to the engine control unit (ECU), allowing it to adjust the spark timing for optimal peak pressure timing.
- Maximized Efficiency and Power Output: By fine-tuning the spark timing based on real-time pressure measurements, Koenigsegg maximizes both efficiency and power output.
- Improved Engine Performance: This technology ensures that peak pressure occurs precisely when it should, resulting in improved engine performance.
Conclusion
The Koenigsegg Jesko’s engine is a testament to the brand’s commitment to pushing the boundaries of automotive engineering. With its monstrous power output, fuel flexibility, unique features such as triple fuel injection and tumble flow intake ports, and innovative solutions like the carbon fiber tank and pressure sensors, the Koenigsegg Jesko’s engine stands out as a true marvel of modern engineering. As the automotive industry transitions towards hybrid and electric powertrains, the Jesko marks the end of an era for Koenigsegg, leaving behind a legacy of breathtaking performance and engineering excellence.
