Throttle-body injection (called TBI by General Motors and Central Fuel Injection (CFI) by Ford) or single-point injection was introduced in the 1940s in large aircraft engines, (then called the pressure carburetor) and in the 1980s in the automotive world. The TBI system injects fuel at the throttle body (the same location where a carburetor introduced fuel). The induction mixture passes through the intake runners like a carburetor system, and is thus labelled a "wet manifold system". The justification for the TBI/CFI phase was low cost. Many of the carburetor's supporting components could be reused such as the air cleaner, intake manifold, and fuel line routing. This postponed the redesign and tooling costs of these components. Most of these components were later redesigned for the next phase of fuel injection's evolution, which is individual port injection, commonly known as MPFI or "multi-point fuel injection". TBI was used extensively on American-made passenger cars and light trucks in the 1980 to 1995 timeframe and some transition-engined European cars throughout the early and mid 1990s.
Gre za bencinski motor z direktnim vbrizgom in turbino. Večina turbo motorjev do nedavnega ni bila z direktnim vbrzigom, a to niti ni toliko pomembno.
Bolj pomemben je hiter razvoj teh motorej. Torej če pogledaš graf krivulje navora starejših turbo motorjev ni primerljiv z novimi.
V planu pa je še izboljšnje tega motorja, ko bo dobil multiair. Prvi bo multiair dobil 1.4 motor, brez tubine in z turbino, o multiairu je bilo zdaj že precej napisanga na forumu. Skratka to bo res neka nova zadeva, turbo in direktni vbrizg pa je že precej stara, kot tudi dizelski motorji, a so razcvet doživeli šele zdaj, podoben razvoj pa zdaj sledi še pri tubo bencinarjih.
Fiat je zdaj že predstavil multiair (prvi bo MiTo Septembra), v kratkem pa lahko pričakujemo še Multi-Jet 2, ki bo veliko postoril na navoru v spodnjih obratih in izpustu emisij pri deizelskih motorjih.

torej neka stara masina ki je navita?
to kar si citiral nima nobene veze s tem motorjem.
alfin 1.8 TBi je sodobna turbo masina.
Najbrž povpraševanje... Ali pa že vnaprejšnja priprava na nov davek - DMV, da bodo ko bo ta davek začel veljati rekli, da se "pri njih cena ni spremenila" in da tega davka niso prenesli na kupca
