A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.

Methanol is a high octane fuel that is also extremely resistant to detonation. It has a tendency to absorb heat out of the air – something known as “latent heat of vaporization.” The water also absorbs heat and provides a further cooling effect as the finely atomized water/methanol mix is pumped into the engine. The cooler, denser intake charge reduces the chances of detonation even as the high-octane methanol boosts power.

Why Use Methanol Injection Fuel?

1. Increase the engine working power
2, Cooler intake temperatures allow you to run more aggressive timing and/or boost (forced induction applications)
3, Reduced chance of detonation
4, More economical for the street: water/methanol is a less expensive high-octane alternative to pure race gas for guys running high compression engines on the street
5, Built-in engine maintenance: The atomized water effectively steam cleans the valves, valve seats, and even the piston tops and intake, reducing carbon build up

Working of a Four Stroke Methanol Engine

A stroke is the movement of the piston from the top, to the bottom of the cylinder. the Four Stroke Petrol Engine uses a cycle of four strokes and Methanol as the fuel. Each cycle includes 2 rotations of the crankshaft and four strokes, namely:
1.An Intake Stroke
2.A Compression Stroke
3.A Combustion Stroke also called Power Stroke
4.An Exhaust Stroke


1, Powerful Performance: While it starts, the rotate speed can up to 2500-9600rpm / Mins. 
2, Fuel: Using methanol as fuel. The fuel formula is generally: 20% castor oil, nitromethane 5-30%, the rest is methanol; this product does not require high concentration methanol fuel, and can be used at a concentration of 20-25%. The process of moving from one end of the cylinder to the other when the piston reciprocates within the cylinder is called a stroke.
3, Parts Required for Operation:  Requires a 7.4v or 11.1v battery to start the battery. The battery needs a T plug, the female end is on the engine side, and the electric fire head is needed. The electric fire head is a general-purpose product, which can be used in our shop or in other stores.
4, Priority Gift Option for Many Applications: The four-stroke engine can used on 1:10, 1:12, 1:14 scale car model or ship model and other equipment. Also, it can be used for classroom display as teaching Aids. Besides, it is ideal Gift for engine lovers.


1, Do not touch the motor fan with your hands to avoid scratching. 
2, Do not touch the cylinder department with your hands to prevent burns.
