STRUCTURE OF FUEL RAIL-FOR LPI V-ENGINE

摘要

The present invention relates to a structure of a fuel rail for a LPI (Liquefied Petroleum Injection) V-engine, and fuel rails 2 and 3 of Banks 1 and 2 are connected to each of a fuel supply hose 1 and a fuel return hose 4 in parallel. Therefore, temperature difference between the fuels of both banks is decreased and difference between air-fuel ratios caused by pressure difference is decreased, so that air-fuel ratios of both banks can be easily controlled to approach an optimum air-fuel ratio. As a result, it is possible to reduce the amount of harmful exhaust gas.
