![]() ![]() Typically, the only thing all fuel injection systems have in common is a lack of carburetion. The term "fuel injection" is vague and comprises various distinct systems with fundamentally different functional principles. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake air accelerated through a Venturi tube to draw fuel into the airstream. ![]() In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. ![]() Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. diesel engines), and many spark-ignition engines (i.e. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines.Īll compression-ignition engines (e.g. This tension is managed by a map function of the fuel pressure (rail pressure) and the injectors temperature (estimated from the engine temperature), these two values beeing received by CAN-BUS from the Commander engine management ECU.A cutaway model of a petrol direct-injected engineįuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. The injectors command tension is dynamically tuneable to adapt to the needs of the injectors to drive. Average maximum number of injections for all channels cumulated : 18000 injections/mn (6000 t/mn - 6 cylinders - 1 injection per cylinder, 9000 rpm - 4 cylinders - 1 injection per cylinder).Maximal power delivered to injectors for the peak current: 36 watts.Injection covering of a channel on the other one (between cylinders) allowed.Inputs commands by the ground, 1 KOhm pull-up resistor to +12V After Key integrated into the driver.The housing of the driver being used to dissipate this temperature, it can reach temperatures higher than 100 ☌. The strong power delivered in case of extensive use (high engine rpm and important number of injections by engine cycle, high tension of injectors) provokes a strong rise of the internal temperature. It is forbidden to manipulate the driver or the connections of its loom within the 3 minutes following its complete switch off. ![]()
