Is Toyota Direct Injection

Toyota uses its blended approach of port and direct fuel injection to give the best possible performance, emissions and economy. It is difficult to say when the port, direct or both injectors are active because it depends on many variables like throttle position, load, engine speed and even engine temperature. The answer is bringing fuel to the fire by two separate paths, and a few makers already are fitting their engines with both port and direct injection.

Toyota introduced this technology, which it. Toyota began using gasoline direct injection in the late 1990s, with broader adoption in the mid-to-late 2000s and widespread use by the 2010s. Today, direct injection (often via the D-4S dual-injection system) is a standard feature on many Toyota and Lexus engines.
