Definitions of Terms (Mechanical Meanings)

Torque (T)
A rotational force that causes a shaft to twist, measured in N·m.

Load
Total resisting torque acting on the crankshaft from vehicle inertia, drag, and friction.

Crankshaft
A rotating shaft converting linear piston force into rotational motion.

ICE (Internal Combustion Engine)
A machine producing torque via combustion pressure inside cylinders.

ERS Electric Motor (EM)
An electromagnetic machine applying torque directly to a rotating shaft.

BMEP (Brake Mean Effective Pressure)
Average effective pressure acting on the piston to produce engine torque.

Cylinder Pressure (Pcyl)
Instantaneous gas pressure inside the combustion chamber.

---

Mechanical Load-Sharing at the Crankshaft

Mechanical Principle
The crankshaft is a torque summation point. It reacts only to net torque, regardless of source.

Torque Balance (conceptual)
ICE Torque + Motor Torque − Load Torque = Crankshaft Acceleration

Without ERS:
All torque comes from combustion. Pistons, rods, and crankshaft carry full load.

With ERS:
Electric motor applies torque in the same rotational direction, reducing required combustion torque.

• Lower crankshaft torsional stress
• Lower bending moment on crank webs
• Reduced cyclic fatigue

Cylinder Pressure & BMEP Reduction

Torque–Pressure Relationship
Engine torque is proportional to BMEP and displacement.

Load Sharing Effect
When the motor supplies part of the torque, the engine requires lower BMEP to achieve the same vehicle output.

1. Lower BMEP
2. Lower peak cylinder pressure
3. Lower piston force (Pcyl × Ap)
4. Lower connecting rod compression
5. Lower crank pin and bearing load

Torque & Pressure Comparison

Condition	ICE Torque (N·m)	Motor Torque (N·m)	Total Torque (N·m)	BMEP (bar)	Cylinder Stress Level
No ERS	300	0	300	18	High
ERS Active	200	100	300	12	Reduced

Mechanical Truth (Summary)
ERS increases vehicle power by mechanically sharing crankshaft load, lowering combustion pressure while maintaining or increasing total driveline torque.

🇬🇧 English Section: KERS vs ERS in Formula 1

🏁 Formula 1 Hybrid Technology: KERS and ERS

Formula 1 hybrid technology evolved in two major stages: KERS (first generation) and ERS (modern, fully integrated power unit). The shift marked a massive step toward efficiency and performance.

1️⃣ KERS: The First Boost Button (2009–2013)

KERS stands for Kinetic Energy Recovery System. It was F1’s early hybrid system designed to recover energy lost during braking and provide the driver with a temporary power boost.

How KERS Worked:

• Recovery: During braking, a generator converts kinetic energy into electrical energy.
• Storage: The energy is stored in a small battery or flywheel.
• Deployment: The driver manually presses a “boost” button on the steering wheel to release the stored energy.

Feature	KERS Specification
Peak Power	~80 hp (~60 kW)
Energy Capacity	~400 kJ per lap
Usage	Manual control for ~6–7 seconds per lap
Limitation	Limited power, heavy, difficult cooling, not integrated with engine control.

2️⃣ ERS: The Modern Hybrid System (2014–Present)

ERS stands for Energy Recovery System. It replaced KERS in 2014, expanding the concept into a full, intelligent hybrid system integrated directly into the engine’s Power Unit (PU).

ERS consists of two main components: ERS-K (kinetic) and ERS-H (heat).

A. ERS-K: Successor to KERS

This component performs the same job as KERS—recovering braking energy—but with much greater efficiency and power.

Feature	ERS-K Specification
Peak Power	~160 hp (Double KERS)
Energy Capacity	Up to 2 MJ per lap (~5× KERS)
Operation	Automatic with complex algorithms; driver selects modes (e.g., Overtake, Charge).

B. ERS-H: The Game Changer

ERS-H (Heat) has no KERS equivalent. It is a major upgrade that harvests heat and energy from the turbocharger.

• Function: Recovers exhaust heat and turbine spin, sending energy directly to the battery or straight back to the turbo.
• Benefit: Eliminates turbo lag and provides continuous energy flow throughout the lap, significantly boosting fuel efficiency.

🎯 Final Comparison: KERS vs ERS

Feature	KERS (2009–2013)	ERS (2014–Present)
Peak Extra Power	~80 hp	~160 hp + Turbo Energy
Energy Recovery	Only Braking (Kinetic)	Braking (ERS-K) + Turbo Heat (ERS-H)
Energy per Lap	~400 kJ	~2 MJ + Thermal Unlimited
Driver Control	Manual Button	Automated + Selectable Modes

Summary: KERS was a hybrid "boost button." ERS is a powerful, integrated hybrid engine system that delivers roughly 25–30% of a modern F1 car’s total power, defining the modern era of Formula 1.

🇮🇩 Bagian Bahasa Indonesia: KERS vs ERS dalam Formula 1

🏁 Teknologi Hibrida Formula 1: KERS dan ERS

Teknologi hibrida Formula 1 berevolusi dalam dua tahap utama: KERS (generasi pertama) dan ERS (unit daya modern yang terintegrasi penuh). Pergeseran ini menandai langkah besar menuju efisiensi dan performa.

1️⃣ KERS: Tombol Dorongan Pertama (2009–2013)

KERS adalah singkatan dari Kinetic Energy Recovery System (Sistem Pemulihan Energi Kinetik). Itu adalah sistem hibrida awal F1 yang dirancang untuk memulihkan energi yang hilang saat pengereman dan memberikan dorongan daya sementara kepada pembalap.

Cara Kerja KERS:

• Pemulihan: Saat pengereman, generator mengubah energi kinetik menjadi energi listrik.
• Penyimpanan: Energi disimpan dalam baterai kecil atau roda gila (flywheel).
• Penggunaan: Pembalap secara manual menekan tombol “dorongan” (boost) pada kemudi untuk melepaskan energi yang tersimpan.

Fitur	Spesifikasi KERS
Daya Puncak	~80 hp (~60 kW)
Kapasitas Energi	~400 kJ per putaran
Penggunaan	Kontrol manual selama ~6–7 detik per putaran
Keterbatasan	Daya terbatas, berat, pendinginan sulit, tidak terintegrasi dengan kontrol mesin.

2️⃣ ERS: Sistem Hibrida Modern (2014–Saat Ini)

ERS adalah singkatan dari Energy Recovery System (Sistem Pemulihan Energi). Ini menggantikan KERS pada tahun 2014, memperluas konsep menjadi sistem hibrida cerdas penuh yang terintegrasi langsung ke Power Unit (PU) mesin.

ERS terdiri dari dua komponen utama: ERS-K (kinetik) dan ERS-H (panas).

A. ERS-K: Penerus KERS

Komponen ini melakukan fungsi yang sama dengan KERS—memulihkan energi pengereman—tetapi dengan efisiensi dan daya yang jauh lebih besar.

Fitur	Spesifikasi ERS-K
Daya Puncak	~160 hp (Dua kali lipat KERS)
Kapasitas Energi	Hingga 2 MJ per putaran (~5× KERS)
Pengoperasian	Otomatis dengan algoritma kompleks; pembalap memilih mode (misalnya, Salip, Isi Daya).

B. ERS-H: Pengubah Permainan

ERS-H (Panas) tidak memiliki padanan dalam KERS. Ini adalah peningkatan besar yang memanen panas dan energi dari turbocharger.

• Fungsi: Memulihkan panas gas buang dan putaran turbin, mengirimkan energi langsung ke baterai atau langsung kembali ke turbo.
• Manfaat: Menghilangkan turbo lag dan memberikan aliran energi berkelanjutan sepanjang putaran, meningkatkan efisiensi bahan bakar secara signifikan.

🎯 Perbandingan Akhir: KERS vs ERS

Fitur	KERS (2009–2013)	ERS (2014–Saat Ini)
Daya Tambahan Puncak	~80 hp	~160 hp + Energi Turbo
Sumber Pemulihan Energi	Hanya Pengereman (Kinetik)	Pengereman (ERS-K) + Panas Turbo (ERS-H)
Energi per Putaran	~400 kJ	~2 MJ + Termal Tak Terbatas
Kontrol Pembalap	Tombol Manual	Otomatis + Mode yang Dapat Dipilih

Ringkasan: KERS adalah "tombol dorongan" hibrida. ERS adalah sistem mesin hibrida yang kuat dan terintegrasi yang memberikan sekitar 25–30% dari total daya mobil F1 modern, mendefinisikan era modern Formula 1.
