Measuring method of oil return blow-by gas quantity of supercharger

Abstract

The invention discloses a pressurizer oil returning gas fleeing amount measuring method which comprises a step 1, namely returning oil of a pressurizer is first guided into an oil-gas separator for gas collecting; a step 2, namely a gas flow meter connected with the oil-gas separator is used for measuring the oil returning gas fleeing amount collected by the oil-gas separator and storing the measuring results in a recorder; a step 3, namely the pressurizer returning oil in the oil-gas separator is guided back to an engine oil bottom shell. According to the method, the pressurizer returning oil first flows to the oil-gas separator for gas collecting, the gas flow meter connected with the oil-gas separator is used for measuring the gas fleeing amount in the oil-gas separator and storing the measuring results in a recorder, then the returning oil flows back into the engine oil bottom shell, engine oil is used for separating gas above the oil-gas separator and gas above the oil bottom shell, gas in an engine crank box is prevented from entering the oil-gas separator, gas in the oil-gas separator is prevented from entering the engine crank box, measuring is accurate, and operation is simple.

Description

technical field [0001] The invention relates to the field of engines, in particular to a method for measuring the oil return blow-by gas volume of a supercharger. Background technique [0002] like figure 1 As shown, the oil return pipe 11 of the existing engine supercharger 1 communicates with the supercharger oil return port above the engine oil in the engine oil pan 2 . The oil return pipe 11 of the engine supercharger 1 is arranged above the engine oil level in the engine oil pan 2, the engine supercharger 1 returns oil to the engine oil pan 2 through the oil return pipe 11, and the gas in the oil return pipe 11 can enter In the crankcase, at the same time, the gas in the crankcase can also enter the oil return pipe 11, because the gas in the oil return pipe 11 is not isolated from the gas above the engine oil pan 2, so that the amount of blow-by gas in the oil return of the engine supercharger 1 Impossible to measure accurately. Contents of the invention [0003] T...

Problems solved by technology

The oil return pipe 11 of the engine supercharger 1 is arranged above the engine oil level in the engine oil pan 2, the engine supercharger 1 returns oil to the engine oil pan 2 through the oil return pipe 11, and the gas in the oil return pipe 11 can enter In the crankcase, at the same time, the gas in the crankcase can also enter the oil return pipe 11, because the gas in the oil return pipe 11 is not isolated from the gas above the engine oil pan 2, so that the amount of blow-by gas in the oil return of the engine supercharger 1 cannot be measured accurately
