System and method for detecting air inlet uniformity of V-shaped supercharged multi-cylinder methanol engine

The invention discloses an air inlet uniformity detection system and method for a V-shaped supercharged multi-cylinder methanol engine, and belongs to the field of methanol engine manufacturing. Comprising a boost pressure sensor arranged in a boost pressure pipe, a first air inlet pressure sensor arranged in an outlet pipe of an intercooler, a second air inlet pressure sensor arranged on an air inlet pipe, a plurality of third air inlet pressure sensors arranged on an air inlet manifold and a plurality of air-fuel ratio sensors arranged on an exhaust manifold. The total air-fuel ratio sensor and the storage display device are arranged in the exhaust manifold; according to the detection method, by setting a multi-point pressure and air-fuel ratio data acquisition mode, intake and exhaust related parameters of each independent cylinder of the V-shaped supercharged multi-cylinder methanol engine are monitored, and the single-cylinder methanol spraying amount is accurately corrected according to the data; theref
