Combustion engines have come a long way since they were invented over a hundred years ago. Of all the innovations introduced since then, one of the best is the fairly recent creation of direct fuel injection: it gives you Increased Power and Efficiency where you need it most.
With great power, though, comes great vehicle carbon build-up?
In these engines, the fuel is directly injected into the combustion chamber of each individual cylinder, and no longer passes through the intake valves – and no longer keeps them clean through constant contact. This means that over time, deposits of carbonised fuel and oil build up both on the intake tract and its valves. This can reduce efficiency, oil life, and throttle response, as well as causing rough idling or vibrations. And the worst part? This process cannot be prevented!
