Today, the requirements for an internal combustion engine are higher than ever: minimum emissions, maximum power, low fuel consumption, high efficacy within a wide RPM range, etc. Engineers implement lots of interesting solutions to cover all the needs, and forced induction systems belong to the most effective equipment in this regard. Pretty much any modern diesel engine has a turbocharger, and more and more gasoline motors get this tried-and-tested technology to take engine performance to a new level. Ford Focus models also have a turbocharged engine that features direct injection and a variable valve timing system.
Meanwhile, a turbocharger also has its own drawbacks. With this part under the hood, the engine gets more complex, potentially less reliable, and less forgiving if you use the wrong motor oil or don't change it timely. While the engine is running, the turbocharger's impeller spins at an extremely high speed, many times faster than the crankshaft, and it's subject to extreme temperatures and friction. Soon or late, your turbo can start malfunctioning, which results in poor performance, blue or black exhaust smoke from the tailpipe, siren noise, etc. Don't postpone the repair job; if you need quality replacement parts, browse our Ford Focus turbochargers inventory.
