    摘要： In a cooling apparatus for an engine, a water jacket is divided into two parts, namely a forcible circulation part located chiefly round a cylinder head, and a natural convection part located chiefly round a liner of a cylinder block. The natural convection part is filled at its upper space with a cooling water and at its lower space with a cooling medium different from the cooling water. The cooling medium has a boiling point around a temperature zone to cool the liner, and also has a specific gravity larger than that of the cooling water and immiscible with the cooling water.

    摘要： An intake port device comprises an intake port (9) formed by a straight part (13) and a helical part (15), and a valve (17) disposed adjacent to the inlet of the intake port. In order that intake air flow having a large swirl ratio can be supplied to an engine without being encountered with a large resistance even in a light-loaded condition of the engine, the valve (17) is held in its closed position without causing any sharp decrease in the coefficient of intake air flow when closed. In a modification of the intake port device, the valve (17) holds open the lower half of the intake port 9 in its closed position, so that intake air flow having a large swirl ratio can be supplied without being encounted with a large resistance even when the load of the engine is light. In another modification of the intake port device, the free end of the valve (17) is bent and deformed in the downstream direction of intake air so that the flow of intake air may not be encountered with a large resistance.

    摘要： A combustion control system for a lean-burn engine, to be mounted on an automotive vehicle, uses probabilistic and statistical nature of combustion variance upon lean-burn operation to obtain reliable combustion control. The system detects a variance value in angular acceleration of a rotating member driven by the engine, normalizes the variance value in accordance with an operating state of the engine to determine a normalized variance value. The system also compares the normalized variance value with a predetermined threshold value to obtain a deteriorated combustion determining value. The system compares the deteriorated combustion determining value with a predetermined reference value and controls a combustion variance adjustment element so that the deteriorated combustion determining value matches the reference value.
