Build a Running V-Twin Engine You Can See Through — 867 Pieces, 4 Speeds, Mist & Sound

Included:

• 867 precision ABS bricks — staged in numbered bags by build phase
• Transparent cylinder cover — reveals pistons, rocker arms and valves in motion
• Motor, spray, light and sound modules — pre-installed at the factory
• Display base with engraved nameplate
• Full-colour illustrated step-by-step instruction manual

No soldering needed. The electric parts come built into the modules; you fit the wiring as the manual directs while assembling. When the engine is done, load 6 AAA batteries, add clean water to the mist tank, and switch it on.

The power module drives multiple internal gears, belts and transmission parts at once. Switch it on and the cylinders, gears and rocker arms move in a coordinated sequence for a realistic running-engine effect.

• Four speed settings change how fast the mechanism runs
• Built-in light and sound modules add simulated start-up, idle and acceleration sounds
• Lights pick out the key mechanical areas — sight, sound and motion together for real display presence

A spray module puts out a visible mist during operation, so the engine looks like it's giving off exhaust or steam as it runs.

Use clean water only and don't overfill the tank. Keep the mist away from eyes, face and other electronics.

Two cylinders sit in the classic V arrangement. Through the clear cover you can see the cylinder block, piston movement, rocker arms, valves and crankshaft area — a hands-on look at how a real engine turns reciprocating motion into rotation.

Materials & display: Main parts are high-toughness ABS. Silver metallic bricks give it a realistic engine look, while transparent bricks highlight the inner mechanism. It mounts on a stable display base that holds the engine at a front-on viewing angle for desktop or shelf display.

Building it demonstrates gear transmission, crankshaft movement, piston motion, valve operation and belt drive. It's a clear way to understand how an engine is put together and how its parts work in sequence — while building patience, spatial reasoning and mechanical observation.

BR0014 suits mechanical hobbyists, STEM learners aged 14+, and adult collectors who want a display piece that actually runs. The transparent cover makes it a teaching tool as much as a model — you can see every moving part. It's a great gift for anyone interested in engineering, automotive mechanics, or how things work.

Compact gift box (22.8 × 10.6 × 33.8 cm). Requires 6 AAA batteries and clean water — not included. Ages 14 and up.

Small parts: Contains small bricks — choking hazard. Age 14+. Keep small parts away from children under 3. Don't force the gears or electronic parts. Build strictly by the manual.

Batteries: Use 6 AAA batteries (not included). Don't use incompatible types or mix old and new. Remove them when not in use for a long time.

Water mist: Clean water only, and don't overfill. Keep the mist away from eyes, face and other electronics, and keep water out of the gear and light areas.

It actually runs. The power module drives multiple internal gears, belts and transmission parts at once. Switch it on and the cylinders, gears and rocker arms move in a coordinated sequence — a realistic running-engine effect. Add clean water and it also produces a visible mist.

It requires 6 × AAA batteries (not included). Don't mix old and new batteries, and remove them when not in use for a long time. The motor, spray, light and sound modules are pre-installed at the factory — you only need to fit the wiring during assembly.

A spray module produces a visible mist during operation, making the engine look like it's giving off exhaust or steam. Use clean water only — no oils or additives. Don't overfill the tank, and keep the mist away from eyes, face and other electronics.

Four speed settings change how fast the mechanism runs. You can switch between them to see the engine operate at different rates — from a slow idle to a faster run.

Mid-difficulty. The gear transmission, belt drive and valve mechanism are the most rewarding sections to assemble. Numbered bags and a full-colour illustrated manual keep each phase manageable. Suitable for ages 14 and up; one to two comfortable sessions.

Yes. The model is built from standard ABS bricks with a firm, consistent clutch. You can disassemble and rebuild it — the transparent cover comes off, and the internal mechanism can be re-assembled following the manual.
