Engine Simulator is a physics-based piston engine sandbox. The sound and motion come from a real rigid body simulation of the crank, pistons, valves, and combustion, not recordings. Start an engine, work the throttle, and tune its fuel and ignition maps in the ECU. Build one from scratch (layout, bore, stroke, cam, firing order) or describe what you want and have it generated on device. Watch it run in 3D, read live power and torque on the dyno, or push it past the limiter until it breaks. Post your engines to the global leaderboard and compare against other builders. Engine Simulator for iOS is an unofficial port. It is not affiliated with, endorsed by, or supported by AngeTheGreat (Ange Yaghi), the creator of the original open source Engine Simulator.

Model Engine Builder
Read full descriptionHide full description
Build a miniature engine one part at a time in a retro pixel workshop. Choose from eight designs: diesel, OHV, DOHC, two-stroke, parallel twin, inline four, V-twin and boxer four. Fit parts in order, tighten bolts to the right torque, adjust each engine’s setup and time its ignition. The same engine model appears in selection and assembly. Follow moving pistons, connecting rods and the compact DOHC timing chain as you build. Every stage contributes to a score out of 1,000. Keep a personal best and recent build history for each engine on your device. Three engines are available from the start. Unlock the others by completing optional rewarded ads. The non-consumable Remove Ads purchase removes advertising and unlocks all engines; purchases can be restored. Play in English, Korean, Japanese, French, Spanish, German, Traditional Chinese, Thai, Italian or Hindi. Change language in the globe menu. Advertising privacy choices are available where required. A stylized assembly and timing game, not a repair manual or engineering simulator. Compete on a separate Game Center leaderboard for each of the eight engines. Online rankings require Game Center sign-in.

Verdict
The clearest difference is ads: Engine Simulator at none against Model Engine Builder's shown. Engine Simulator also leads on chart position (#27 vs unranked). Model Engine Builder's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.6 vs 18.6). On price, in-app purchases and device support there is nothing between them.
