Engine Generator builds a complete internal combustion engine in one click, and every part of it moves. Pistons, connecting rods, crankshaft, camshafts, valves, springs, rocker arms, pushrods, timing chain or belt, pulleys, turbochargers and the supercharger all run from a single crank angle, so pressing Play shows the engine running with a real firing order and real valve timing.

Choose any layout: inline with any slant, V with any angle between the banks, narrow VR, W (two VR banks or a three-bank broad arrow), boxer, or a single or twin-row radial. Pick the number of cylinders, the bore and the stroke, and the crankshaft, firing order and displacement follow.

Features

• Inline, V, VR, W, boxer and radial layouts with 1 to 18 cylinders
• Selectable bank angle, VR angle and inline slant
• Crankshaft: auto, flat-plane, cross-plane, split-pin even firing or big-bang, with full, partial or no counterweights
• Firing order and firing intervals computed from the geometry, shown in the panel
• DOHC, SOHC or pushrod (OHV) valvetrains with 1 to 3 intake and 1 to 2 exhaust valves per cylinder
• Cam lobes shaped from the same lift curve that drives the valves, with adjustable lift, duration and lobe separation
• Timing chain, toothed belt or gear train, exposed or behind a closed timing cover
• Gasoline with spark plugs and coils or a distributor and plug wires, or diesel with common-rail injectors and glow plugs
• Carburetor, port or direct injection; plenum or individual throttle bodies; tubular headers or log manifolds
• Naturally aspirated, turbo, twin-turbo (including hot-V) or a belt-driven Roots supercharger
• Water-cooled blocks or finned air-cooled cylinders
• Side and front cutaways that show every moving part, with colored intake, compression, combustion and exhaust gas
• Alternator, water pump, serpentine belt, starter, oil filter, flywheel and a propeller on radial engines
• 24 engine presets to start from: 2JZ inline-6 twin turbo, small-block V8, flat-plane V8, V12, W16, VR6, boxers, V-twin, radial 9 and more
• Bake Animation turns the motion into keyframes for export to game engines and other apps
• Every part is its own object at real-world scale, and all of it stays editable

Every driver uses Blender's simple expressions, so engines animate even with Python auto-run disabled.

Requires Blender 4.2 or newer. Tested on Blender 4.2, 4.5 and 5.2 LTS.
