How Does 4-Stroke Engine Works?

The TOYAN FS-L400BGC engine operates by igniting gasoline, which powers pistons to turn a crankshaft. This rotational motion is harnessed for various applications, such as driving vehicles or generating power.

Stability and Speed:

Engineered for high-speed operations, our dual oil-seal crankshaft prevents oil leakage while a support bracket enhances performance, achieving a maximum speed of 13500rpm.

Performance Upgrade:

The valve/camshaft upgrade extends lifespan by 3.5 times, while the high-angle camshaft heightens throttle response for a thrilling ride.

Reliability at its Core:

Dual synchronous pulleys ensure timing precision even at high speeds, while the redesigned carburetor and intake manifold make engine startup a breeze.

Ready for More:

An enlarged oil sump allows for future independent lubrication upgrades, so you can take your engine to new heights.

Distributor

This engine is ignited using a distributor, a distributor ignition system that is relatively simple and reliable. A distributor ignition system is a traditional ignition system used to ignite a gasoline engine and usually includes a distributor, ignition coil, glow plug, and ignition timing mechanism.
