It does not have secondary air injection.
SRI = Sport Rally Injection
fuel injection yes, turbo no
Si on a ford stands for sport injection
should be fuel injection (SI sequential injection) Most Hondas made up until about 1988 were carbureted, at which point they all switched to fuel injection. (The main difference then was whether they used dual point injection or multipoint injection...the Si models used multipoint.) Prior to 1988, you could tell if a Honda sport model was carbureted by the model designation. "S" was used for the sport models that were carbureted (S = Sport), while "Si" stood for the sport models that were fuel injected (Si = Sport Injected). A prime example was the Prelude, which offered a twin-carb version called the "S" and a fuel injected version of the same car called "Si." This naming strategy was common in the 80s with other manufacturers as well. Take, for instance, the Merkur XR4Ti. The "T" stood for "Turbocharged" while the "i" stood for fuel "injection," in the same was that the "i" stands for fuel injection on Honda Si models.
Grand Sport Injection an indication to the high performance-engines
Grand Sport Injection. It has so do with the way that your fuel is injected into your engine.
si on a Honda civic is the body type it means sport injection
Im not 100% positive, but if I remember correctly its "Grande Sport Injection"
These days all cars come with fuel injection. Cars with fuel injection do not have a carb. They do have a throttle body, which controls the air entering the engine, but unlike a carb, do not meter the fuel at the same time.
The 318 is the car series, 3 series, 1.8 or 1.9l 4cyl engine, the i is for fuel injection, the s is for sport package.
There is no carburetor on these new fangled cars. Darn things have the newer port fuel injection. Not even throttle body injection, which kind of LOOKS like a carburetor. It does have a throttle body though, at the junction of the air intake hose and the intake manifold.
