Fuel supply for multi-cylinder internal combustion engine - involves fuel quantity distributor with tubular distributor housing, fuel forward feed connection and fuel back flow connection

摘要

There are two fuel quantity distributors (1.1, 1.2), and in the second receiving hole (7) of the second quantity distributor (1.2) is accommodated a pressure check connection (10). The pressure regulating valve (9) and the pressure test connection have conformable connecting areas for fitment in the fuel quantity distributors. The pressure check connection in the second accommodation hole of the first fuel quantity distributor (1.1) in the fuel flow direction (12) and the pressure regulating valve in the second accommodation hole of the second fuel quantity distributor (1.2) are arranged in a fluid tight manner. The fuel quantity distributors are made of a fuel and heat-resistant polymer material. ADVANTAGE - The arrangement is very simple and cost-effective, with deviations in pressure within the fuel supply system being recognised as faults.
