Port and helix fuel injection pump
WebInline Fuel Injection PumpsIn 1927 Robert Bosch produced the first practical diesel pump. This design enabled the newly developed diesel engine to become a viable engine for many applications. The method offuel metering on this initial pump was port and helix, (high- pressure metering). WebThis system has an injection pump and an injection valve for each cylinder. Most injection valves are located in the precombustion chamber, while the injection pumps are located in a common housing. As with other diesel injection systems, proper operation depends on the quality and cleanliness of the fuel.
