Most of the time itâs a good smell, but sometimes, itâs really not,â says cleaning expert and best-selling author Linda Cobb, aka The Queen of Clean.
Making the world better, one answer at a time. Nissan's swirl control valve (SCV) is an actuator that modulates intake air flow into the engine to increase low and high engine speed efficiency.The SCV does this by constricting the intake opening during idling and low engine speeds.nswered by The Community.

The semilunar valves (SV) are two valve structures that sit between the right ventricle and the pulmonary artery and between the left ventricle and the aorta. The flaps of the valves open and close to allow the unidirectional flow of blood out of the heart, while preventing backflow of blood.The valve between the left ventricle and aorta is called the aortic valve and the valve between the pulmonary artery and right ventricle is called the pulmonary valve.The heart has two types of valves: the atrioventricular (AV) and semilunar.he flaps of the valves open and close to allow the unidirectional flow of blood out of the heart, while preventing backflow of blood. The valve between the left ventricle and aorta is called the aortic valve and the valve between the pulmonary artery and right ventricle is called the pulmonary valve.
