Latest Patents

Hiroshi's latest patents include the following inventions:

1. **Lubricant Passage System for Internal Combustion Engines**: This patent introduces a unique design where a pump for lubricating oil is mounted on the outer face of the engine's end wall. The system features an oil filter mounted parallel to the crankshaft and a substantially straight sub-gallery that connects the oil pump to the oil filter. The main gallery, in turn, receives lubricating oil from the oil filter and distributes it to branched supply passages that lubricate various engine parts.

2. **Blow-By Gas Recovering System for Internal Combustion Engines**: This innovation addresses the issue of blow-by gas in internal combustion engines. It consists of two blow-by gas outlets located longitudinally along the crankshaft, which communicate with the crank chamber. These outlets connect to a chamber designed for separating blow-by gas from lubricating oil. The recovered blow-by gas is then introduced back into the engine intake system, promoting more efficient combustion.
