Engine LD vs Trans4motor R

Engine Layout Definitions (Engine LD) Understand how piston–crank geometry impacts engine performance. • Explore how layout changes affect engine displacement, rated power, and dynamic forces. • View detailed graphs and data lists: • Displacement volume vs. crank angle • Dynamic forces vs. crank angle • Export values for spreadsheet analysis or basic FEA (finite element analysis). • Interactive simulation: adjust crank rotation with a slider to visualize dimension effects on engine packaging.

The definitive successor to the original Trans4motor is finally here — a new installment that lets you freely explore and animate four-stroke engines on your iPad or iPhone. Created for those who love internal-combustion engines and never tire of their rhythm, mechanics, and beauty. 【Seamless Engine Morphing】 Switch from inline to V configurations, alter bank angles, change cylinder counts, and adjust firing intervals. Every change transforms the engine while it continues running. Camshafts split and merge, crank phasing shifts, valve angles move dynamically — a completely new way to experience engines. 【All-New Transmission Simulation】 For the first time in the series, the gearbox itself is fully visualized. ・3-shaft synchromesh transmission ・2-shaft synchromesh transmission ・Dog gearbox (motorcycle-style) Enter tooth counts manually, or let the app generate realistic gear meshes from gear ratios. Follow shift forks, constant-mesh gears, clutch engagement, and truly see how power flows. 【Deep Engine Specification Editing】 Greatly expanded from the original, allowing a far richer expression of each engine’s character. ・Cylinder count, bore, stroke ・Bank angle, mounting angle ・Firing order, firing interval ・Cam drive (belt / chain / gear) ・Valve train (SOHC / DOHC / OHV / VTEC / Desmodromic) ・Valve diameter and included angle (reflected in the CG model) ・Tire width, aspect ratio, wheel diameter (outer diameter calculated automatically) Recreate everything from spirited singles to distinctive 5-cylinder pulses, modern V4 superbikes, and the bold heartbeat of American V8s. 【Realistic Vehicle Physics】 Not just an animation. Torque curves, vehicle mass, gear ratios, and tire diameter are calculated frame by frame to determine vehicle speed. Shift through the gears and feel how the engine and drivetrain connect as acceleration builds. 【Connect with the “Engines” Sharing Platform】 Share your creations with the world. ・Upload / download ・Share to X (formerly Twitter) ・Community “likes” and voting ・Planned competitions Build a community-driven engine library with fellow enthusiasts. 【GearVision Mode】 Gears, shift forks, clutches — see exactly which components are transmitting power at any moment. A visualized power-flow mode revealing the inner workings of each shift. 【TechTour】 A hands-on learning mode evolved from the series’ interactive tutorials. ・Four-stroke fundamentals ・Firing order ・Synchromesh mechanisms Engines become even more fascinating when you understand how they work. 【Enhanced Engine Sound】 With support from Sound Design Lab LLC, this latest audio method combines single-shot, harmonic, and random-noise components to create a natural and realistic engine presence. Differences in cylinder count and firing intervals come through with greater character and detail. Engine sound is included as a standard feature, not an in-app purchase. 【Preset Engines】 Trans4motor R includes 12 preset engines ranging from classic icons to modern super-sport engines and powerful V8s. ※ For learning and presentation purposes, the engine CG animations run at one-tenth of real-world rotational speed. ※ This app reproduces engines based on publicly available specifications for educational use and is not intended to be an exact replica of actual machinery, dimensions, or designs. ※ Company names and product names mentioned in this app are trademarks or registered trademarks of their respective owners.
