Latest Patents

One of Kanamaru's latest patents is a two-cycle engine lubricating system. This innovative lubricating system is designed for reciprocating machines, such as two-cycle internal combustion engines, with horizontally disposed cylinder bores. The system includes a drain mechanism that allows lubricant to flow from the lowermost crankcase chambers to the upper cylinders. This design ensures uniform lubrication and promotes smooth engine operation. Additionally, a check valve is incorporated to prevent reverse flow, delivering lubricant to both the crankcase chambers and the piston. The lubricant is supplied to the upper area of the piston, ensuring complete lubrication of its circumference and the associated cylinder bore.

Another significant patent by Kanamaru is for a two-cycle motor featuring a fuel injection system for marine propulsion. This arrangement controls a two-cycle marine engine by reducing the firing frequency of the cylinders during low-speed operation. This innovation enhances fuel economy and engine performance by improving scavenging while maintaining uniform firing intervals between cylinders. The invention is versatile and can be applied to various multiple-cylinder engines, including both spark-ignited and diesel engines, without affecting the ignition system.
