What's the difference between inlet cleaning and throttle cleaning?

The difference between inlet cleaning and throttle cleaning: 1, and the cleaning parts are different: inlet cleaning nozzle and inlet; Throttle cleaning idle motor and air flow meter. 2. Different cleaning functions: air intake cleaning can effectively eliminate the problems such as unstable idle speed and poor acceleration of the engine; Throttle cleaning is mainly to remove carbon deposits and improve combustion. There are two main cleaning methods for air intake system: disassembly cleaning and disassembly-free cleaning. Disassembly and cleaning is a cleaning method of disassembling the air intake system and the fuel system, and then cleaning each component. Disassembly-free cleaning can be completed within 0.5 hours, and there are mainly two cleaning methods: "vacuum suction" and "atomizing spray". "Vacuum suction" means that when the engine is running, the cleaning liquid is sucked into the intake manifold from the vacuum hose, and then evaporated due to high temperature, and the deposits are dissolved and brought into the combustion chamber for combustion; "Atomization injection" means that when the engine is running, the cleaning liquid is added into the pressure vessel, pressurized by the air compressor, sprayed by the atomizing nozzle, and then sucked by the natural suction of the air intake system, so that the deposits are dissolved and brought into the combustion chamber for combustion.
