Do the carbon deposits of direct injection vehicles need to be cleaned regularly?

1, in-cylinder direct injection engines generally clean carbon deposits once every 30,000 kilometers. 20,000 yuan to clean the throttle and injector, 40,000 yuan to varnish. Cars will produce carbon deposits after driving for a period of time and need to be cleaned regularly. It is recommended to go directly to the 4S shop, where there are professional tools to operate.

Carbon deposition will occur when the engine is in normal use, which has nothing to do with direct injection in the cylinder. When the engine is used for a period of time, the carbon deposit on the engine is too much to be removed without disassembly. Generally, the carbon deposit is removed by disassembling the air inlet, which is a conventional carbon deposit removal method and will not cause great harm. Direct injection engine is only a technical improvement of naturally aspirated engine. Direct injection technology of naturally aspirated engine is to inject fuel directly into the cylinder for ignition and combustion to do work, and only air enters from the intake manifold. This can make gasoline and air burn better. The computer will constantly change the fuel injection mode according to the working conditions of the engine, and always maintain the most suitable fuel supply mode. The full utilization of fuel not only improves fuel utilization efficiency and engine output power, but also improves emissions. At present, the in-cylinder direct injection technology is very mature, and all major manufacturers have engines using in-cylinder direct injection technology. You can use it safely.
