  • COMBUSTION DEVICE FOR AN ENGINE AND METHOD FOR DESIGNING A PISTON
    Publication number: 20250035065
    Abstract: A combustion device for an engine and a method for designing a piston includes a cylinder head, a cylinder block cooperating with the cylinder head, and a piston disposed in the cylinder block. The cylinder head includes an intake valve setting region and an exhaust valve setting region. The surface of the piston adjacent to the cylinder head includes a first concave surface and a squeezing surface adjacent to the first concave surface. The squeezing surface includes a first squeezing surface corresponding to the intake valve setting region and a second squeezing surface corresponding to the exhaust valve setting region. A combustion chamber is formed between the first concave surface and the cylinder head. The second squeezing surface includes a flow guide groove. The flow guide groove includes two first notches facing the combustion chamber.
