Low Pressure Fuel Injection TRIZ Cases

A fuel distribution connector firmly couples to a motorcycle injector, linking series tubes to resolve layout complexity in limited engine bays.

Integrated control valve regulates fuel pressure between filter and high-pressure pump.

A reinforcing material covers the inlet pipe connection on a flat delivery pipe main body to maintain structural integrity.

Integrating fuel return line into protective cover eliminates bulky housings and leakage risks from screw connections.

A diverter rail fuel injection system integrates a distributor block with the first rail to minimize pressure fluctuations across cylinder rows.

Static geometry pressure regulating valves between injectors and the drain conduit limit cross-talk by attenuating pressure pulses.

Placing the electric motor between throttle bodies and offsetting coil springs reduces vibration and compactifies the V-type engine air intake layout.

Spring-actuated diaphragm valve opens only above pressure threshold to reduce evaporative emissions during diurnal cycles.

A low pressure regulator uses a spring-loaded piston to bypass its filter during flushing mode.

A one-piece forged fuel rail uses integrated reinforcement members to minimize deformation under injector forces while maintaining lightweight construction.

Segmenting the control valve into two independent 2-way units resolves the trade-off between device complexity and motion flexibility in diesel injectors.

Integrated slots and projections secure fuel injectors against rotation, eliminating separate clips and reducing assembly complexity.

A fuel injector mounting assembly secures both ends of the injector to the cylinder assembly using a flexible conduit.

Modular fuel supply piping uses sockets and a stay to connect injectors, enabling adaptable engine configurations.

Self-service joint members open check valves during insertion to prevent fuel leakage and eliminate manual push button requirements.

Plastic fuel distributor housing integrates eccentric cups to lower manufacturing costs while maintaining structural stability for medium-pressure applications.

A fuel injection valve body uses peripheral grooves to recover leaked fluid while maintaining inner sealing pressure.

A throttle body assembly integrates an electronic control unit and fuel injectors to manage fluid flow within a single housing.

A conveying pump forces fuel into the valve chamber to flush vapor bubbles, preventing engine starting failure after shutdown.
