When closed it mus seal the combustion chambers from the intake port Exhaust valves(Component of the internal combustion engine) - CORRECT ANSWER allows waste gases to be removed from the combustion chambers. When closed it must seal the combustion chamber from the exhuast port Camshaft - CORRECT ANSWER Responsile for the opening and closeing of the engines intake and exhaust valves. The camshaft turns at one-half speec of the engines crankshaft Troposphere - CORRECT ANSWER lowest level of the atmosphere, where all weather takes pace. It is the regon of rising and falling pckets of air. Stratosphere - CORRECT ANSWER airflow is mostly horizontal. The thin ozone layer in the upper stratosphere has a high concentration of ozone, a particularly reactive form of oxygen. This layer is primarily responsbile for absorbing the ultraviolet radiation from the sun. Temperature is about - 60 C Mesosphere - CORRECT ANSWER above the stratosphere is the mesophere, which extends to about 90 kilo abut the Earth. The temperature starts to drop again, to as low as - 90 C. This is where we see "falling stars" meteors that fall to the Earth and burn up the atmosphere Thermosphere - CORRECT ANSWER temperature continues to increase with the altitude, with recorded temperatures reaching as high as 2,000 C as its upper limits which extends to several thousan kilmeters above the Earth Warm Front - CORRECT ANSWER When a warm air mass overtakes a cold air mass Lean Mixtures - CORRECT ANSWER When too much ait and not enough fuel would be described. Burn relatively slowly because there is greater space between the fuel molecules and it takes more tim for a flame to jump from particle to particles. Burn much hotter and thus can cause serious engine damage. Ration 17: 2 Radiator - CORRECT ANSWER responsible for transferring heat from the collant to the outside air Radiator cap - CORRECT ANSWER Responsible for maintaining pressure in the system and allowing coolant to transfer between the collant reservoir and the radiator.
