The invention discloses an oil-saving filter screen for an engine oil spray nozzle and a manufacturing method for the oil-saving filter screen. The oil-saving filter screen for the engine oil spray nozzle comprises the following chemical element components in percentage by weight: 25-30% of Mo, 12-15% Cr, 5-8% of Al, 2.5-3.5% of Si, 0.3-0.6% of Y and the balance of Ni. The oil-saving filter screenis manufactured from ball-milling and powder-mixing, pressing and forming and vacuum sintering. The oil-saving filter screen adopts nickel-based high-temperature alloy as the oil-saving filter screenof the oil spray nozzle, has excellent high-temperature and anti-oxidization ability, further can be applied onto a jet engine or other equipment which needs fuel oil atomization in addition to a conventional diesel engine and a conventional gasoline engine, and further can improve fuel oil atomization quality, so that combustion efficiency is improved, the energy-saving emission-reducing effectis better, and energy-saving emission-reducing indexes of a great number of conventional cars are greatly improved; and moreover, the manufacturing method is simple and is beneficial for large-scale production.
