    Sister-in-law's mechanic says the fuel injectors should be cleaned on her 2014 BMW 328 because of carbon buildup, at a cost of $307. Is it necessary?

  3. Parts cleaning - Wikipedia

    en.wikipedia.org/wiki/Parts_cleaning

    The general situation has changed, meanwhile, because of dramatically rising cleanliness requirements for certain components in the automotive industry. For example, brake systems and fuel-injection systems need to be fitted with increasingly smaller diameters and they have to withstand increasingly higher pressures. Therefore, a very minor ...

  4. Fuel injection - Wikipedia

    en.wikipedia.org/wiki/Fuel_injection

    The term fuel injection is vague and comprises various distinct systems with fundamentally different functional principles. The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external.

    Fuel is pumped from the tank to a large control valve called a fuel distributor, which divides the single fuel supply line from the tank into smaller lines, one for each injector. The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors ...

    Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

    en.wikipedia.org/wiki/Rochester_Ramjet

    The Ramjet is a continuous-flow port-injection system. Unlike later fuel injection systems that used electronics, this one is based on purely mechanical principles. The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel ...

  9. Manifold injection - Wikipedia

    en.wikipedia.org/wiki/Manifold_injection

    Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine.
