- 📦Trans4motor R updated to version 1.1.0iOSIntroducing the new “MotionStep” feature, plus a new “VTEC” chapter in TechTour.
We’ve also redesigned the “Engines” sharing site and refined many details throughout Trans4motor R.
■ MotionStep
Tap at any moment to freeze the engine, then step the crank angle forward or backward to take a closer look at the internal mechanics.
While paused, you can still rotate, pan, and zoom the view freely.
■ TechTour
A new “VTEC” chapter has been added, showing how the VTEC mechanism works.
■ Engines
The “Engines” sharing site has been redesigned.
Official engines and user-created engines are now clearly distinguished, and it’s easier to discover official and newly uploaded engines.
New upload rules also let you share more of your engine creations.
■ Editing
Slider controls in the engine editor have been further improved.
While dragging on the slider, values now snap to larger grid increments for quick, coarse adjustment.
Move your finger up or down away from the slider to switch to progressively finer grid increments, making it easy to fine-tune the value you want.
■ Graphs
A crank-angle indicator has been added to the ignition timing and piston position graph, making it easier to follow how they relate to the current crank angle.
■ Other Improvements
• Refined the motion of internal components such as cams and rocker arms
• Improved automatic clutch engagement when launching from a standstill
• Added selectable Normal/Reverse crank rotation for motorcycle engines
• Made the valve angle adjustable across all engine configurations… more - 📦Trans4motor R: first update in 247 daysiOS

About Trans4motor R
For those who live and breathe internal combustion engines.
Explore and customize engines from single-cylinder to V12, plus their gearboxes, in real-time 3D. Change the layout, valve gear, or firing timing and see and hear what happens.
[SEAMLESS ENGINE MORPHING]
Imagine a transparent engine that keeps running as you change its design.
Change the cylinder count, V angle, or valvetrain, and watch the engine smoothly transform into its new configuration without stopping. Crankshaft phasing shifts, camshafts split or merge, and cylinder heads reshape before your eyes. Watch the transformation and discover why engines are built the way they are.
[BUILD YOUR OWN ENGINE]
Choose inline, V, or flat layouts, then fine-tune the details:
• 1 to 12 cylinders
• Bore, stroke, and V-bank angle
• Firing order and ignition timing
• SOHC, DOHC, OHV, VTEC, and desmodromic valve gear
• Timing belt, chain, or gear-driven cams
• Valve diameter and included valve angle
• Reverse-flow or Cross-flow port layouts
• Normal or reverse crank rotation
Recreate a classic sports-car engine, an American pushrod V8, or a high-revving motorcycle engine—or dream up a design of your own.
[SEE INSIDE THE GEARBOX]
Go beyond the engine and explore working transmissions in real-time 3D:
• 2-shaft and 3-shaft synchromesh gearboxes
• Dog Box (motorcycle-style)
• Editable gear tooth counts and ratios
Watch the clutch, shift forks, and gears in action from any angle.
[FOUR WAYS TO EXPLORE]
GearVision
See which gears and components are transmitting power, highlighted in color. Follow the power flow as you shift.
MotionStep
Tap to freeze the engine at any moment. Step the crank angle forward or backward to study the cams, rockers, valves, and pistons. Rotate, pan, and zoom even while paused.
TechTour
Interactive 3D tours that reveal how things work: Four-stroke Engine, Firing Order, Synchromesh, and VTEC. Learn by watching the parts move.
Engines
Share your own engine builds and download creations from users around the world. Browse official and community engines, post your designs, share to X, and give likes. Share engine data across Android and iOS. Contests are planned.
[ENGINE SOUNDS THAT RESPOND TO YOUR SETTINGS]
These aren't just recordings played back at different speeds. Developed with Sound Design Lab, the audio combines individual firing pulses, engine-order tones, and random sound components, synthesized in real time as the engine runs.
Change cylinder count or ignition timing and the engine note changes too.
For example, take an even-firing inline-four's smooth, high-revving scream and change the firing setup to hear the deeper, distinctive uneven-firing note associated with the crossplane crankshaft in Yamaha's YZF-R1.
Engine sounds are included—no extra purchase required.
[VEHICLE PHYSICS MODEL]
Torque curves, gear and final-drive ratios, vehicle weight, tire size, clutch engagement, and tire grip all feed into a real-time model of engine load, RPM, and veh
Explore and customize engines from single-cylinder to V12, plus their gearboxes, in real-time 3D. Change the layout, valve gear, or firing timing and see and hear what happens.
[SEAMLESS ENGINE MORPHING]
Imagine a transparent engine that keeps running as you change its design.
Change the cylinder count, V angle, or valvetrain, and watch the engine smoothly transform into its new configuration without stopping. Crankshaft phasing shifts, camshafts split or merge, and cylinder heads reshape before your eyes. Watch the transformation and discover why engines are built the way they are.
[BUILD YOUR OWN ENGINE]
Choose inline, V, or flat layouts, then fine-tune the details:
• 1 to 12 cylinders
• Bore, stroke, and V-bank angle
• Firing order and ignition timing
• SOHC, DOHC, OHV, VTEC, and desmodromic valve gear
• Timing belt, chain, or gear-driven cams
• Valve diameter and included valve angle
• Reverse-flow or Cross-flow port layouts
• Normal or reverse crank rotation
Recreate a classic sports-car engine, an American pushrod V8, or a high-revving motorcycle engine—or dream up a design of your own.
[SEE INSIDE THE GEARBOX]
Go beyond the engine and explore working transmissions in real-time 3D:
• 2-shaft and 3-shaft synchromesh gearboxes
• Dog Box (motorcycle-style)
• Editable gear tooth counts and ratios
Watch the clutch, shift forks, and gears in action from any angle.
[FOUR WAYS TO EXPLORE]
GearVision
See which gears and components are transmitting power, highlighted in color. Follow the power flow as you shift.
MotionStep
Tap to freeze the engine at any moment. Step the crank angle forward or backward to study the cams, rockers, valves, and pistons. Rotate, pan, and zoom even while paused.
TechTour
Interactive 3D tours that reveal how things work: Four-stroke Engine, Firing Order, Synchromesh, and VTEC. Learn by watching the parts move.
Engines
Share your own engine builds and download creations from users around the world. Browse official and community engines, post your designs, share to X, and give likes. Share engine data across Android and iOS. Contests are planned.
[ENGINE SOUNDS THAT RESPOND TO YOUR SETTINGS]
These aren't just recordings played back at different speeds. Developed with Sound Design Lab, the audio combines individual firing pulses, engine-order tones, and random sound components, synthesized in real time as the engine runs.
Change cylinder count or ignition timing and the engine note changes too.
For example, take an even-firing inline-four's smooth, high-revving scream and change the firing setup to hear the deeper, distinctive uneven-firing note associated with the crossplane crankshaft in Yamaha's YZF-R1.
