Latest Patents

Endo holds a patent for an internal combustion gasoline engine that features an advanced exhaust gas purification system. This system is designed for engines with at least two cylinders, where each exhaust valve communicates with a port passage in the cylinder head. The design includes a pair of adjacent port passages that connect to a common port passage, forming a siamese port passage. A secondary air intake passage with a check valve introduces secondary air through exhaust pulsation, enhancing the purification process. The exhaust pipe connected to the common port passage maintains a constant cross-section to optimize exhaust pulsation effects. Additionally, heat insulation along the siamese port passage and exhaust pipe ensures effective oxidation of unburned constituents. The system is engineered to maintain combustion temperatures below 2000 degrees Celsius, significantly reducing nitrogen oxide emissions.
