WebFeb 12, 2016 · Throttle body injection uses a single fuel injector to inject fuel right before the throttle body. Multi port injection is the most common since the early/mid 90s. Each cylinder gets its own fuel injector mounted in the intake manifold. Direct injection is not very common on gasoline engines, but is growing in popularity. WebDirect injection, by contrast, uses slow-moving air and fast-moving fuel; both the design and manufacture of the injectors is more difficult. The optimisation of the in-cylinder air flow is much more difficult than designing a prechamber. There is much more integration between the design of the injector and the engine. [4]
