Are direct inject engines really efficient?



  1. 0 Votes

    Yes. Direct injection engines with turbochargers or superchargers increase the engine efficiency by up to 12%. And can save $2700 over the vehicles lifetime. In direct injection systems, fuel is injected directly into the cylinder so that the timing and shape of the fuel mist can be precisely controlled. This allows higher compression ratios and more efficient fuel intake, which deliver higher performance with lower fuel consumption.
