Abstract
The utility model belongs to a motor part in specific relating to a piston used by the motor. The utility model is characterized in that an oil groove is arranged on the piston skirt part of the matrix. A plurality of oil holes are arranged in the oil groove. The utility model can effectively improve the lubrication of the piston skirt part and decrease the temperature of the skirt part. Used under normal conditions, the utility model has the outstanding effects of increasing the cold start performance of the motor, increasing the power of the motor by 10 percent and reducing the exhaust emission by 15 percent.
Description
Technical field: the utility model belongs to engine components, is specifically related to the piston that a kind of motor is used.
Background technique: the piston that uses on the available engine, the piston skirt poor lubrication, the one, be prone to pull-cylinder phenomena; The 2nd, reduced the power of motor; The 3rd, the temperature height, the skirt section is expanded big, and the piston cylinder prepareding gap is strengthened, and makes the engine cold-start difficulty.
Summary of the invention: the purpose of this utility model provides a kind of piston skirt and lubricates, and the life-span is long, can reduce the piston of pull-cylinder phenomena.
The technical solution of the utility model is: a kind of piston, comprise matrix, and it is characterized in that: on the position, piston skirt of matrix, be provided with oil groove, several oilholes are set in the oil groove.
Owing to adopt technique scheme, can improve the lubricated of piston skirt effectively, reduce the skirt section temperature, use under normal operation, have the cold starting performance that improves motor, improve engine power 10%, reduce the positive effect of exhaust emissions 15%.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings.A kind of piston is provided with oil groove and oilhole on the piston ring land position of matrix 1, be provided with oil groove 2 on the position, piston skirt of matrix, and several oilholes 3 are set in the oil groove 2.
