ENGINE CORE

Bore

Stroke

Cylinders

qty

0.00 cc total

cc per silinder = π×(bore/2)²×stroke ÷ 1000

Bore

Stroke

Rod length

Intake closing (ABDC)

4T: kompresi efektif setelah intake menutup.

Clearance volume Vc

0.00 :1

DCR = (Veff + Vc) / Vc, Veff = Area × y(θ), y(θ) = posisi piston dari TMA pada θ = 180°+φ.

Bore

Skenario

0.000 mm (end gap per ring)

Rumus: gap = bore × faktor.

FUEL & AIR

Flow injector per buah

cc/min

Jumlah injector

qty

Duty cycle

BSFC

lb/hp·hr

0 HP (maks yang didukung)

Konversi 1 lb/h ≈ 10.5 cc/min. HP ≈ (Σ flow(lb/h) × duty) / BSFC.

Target HP

0 cc/min per injector (kebutuhan)

Gear ratio (gigi dipilih)

ratio

Final drive (sprocket)

ratio

0.0 km/jam

Kecepatan = (RPM × keliling roda) / (primary × gear × final) → mm/menit → km/jam.
