A fuel injection apparatus in which the state of vaporization of the fuel in the internal combustion engine is improved by making the fuel spray injected from the fuel injector not strike the umbrella portion of the intake valve from the front, but be oriented to a position shifted to the right or left of the stem so that the majority of the spray flows in to a valve seat clearance of an annular groove shape formed between the valve face and the valve seat and causes a swirl in the same. The wet amount of the fuel depositing as a liquid film on the umbrella portion and the inner surface of the intake port, which is difficult to evaporate, is reduced.

A mask for covering part of the surface of the material to be coated comprises an aluminum foil, and a film of a resin provided on one surface of the foil and having a high power of adhering to the foil and any film of paint formed on the resin film. The film of paint which is formed on the resin film when the paint applied to the material to be coated is baked in an oven does not peel off and contaminate the interior of the oven. No such paint film peels off and adheres to the coated surface of the coated product, either, but the mask ensures the improved quality of the coated surface.

A washing solution for a color-change washing which contains a medium-boiling and/or high-boiling true solvent having a boiling point of 100.degree. C. or more, and a color-change washing method using that washing solution. In rotary type electrostatic spray coating devices in which a non-aqueous dispersion paint and a titanium dioxide pigment-incorporated paint are used in combination, the washing solution and method are advantageously used as they remove contamination and clogging of the coating device and reduce fire hazards.
