For example, methane is a much more powerful greenhouse gas than carbon dioxide. Over a 100 year period, a molecule of methane (CH4) has 21 times the warming effect as a molecule of carbon dioxide (CO2), even though it stays in the atmosphere for only about 12 years of the 100 year period.he warming impact of different types of greenhouse gases varies according to the warming power of the gas and the length of time it stays in the atmosphere. As shown in Table 1, carbon dioxide has an atmospheric life of 50 to 200 years.
hydraulic manifold definition, hydraulic manifold meaning | English dictionary. hydraulic. n a press that utilizes liquid pressure to enable a small force applied to a small piston to produce a large force on a larger piston.
The Manifold Absolute Pressure (MAP) sensor is a key sensor because it senses engine load. The sensor generates a signal that is proportional to the amount of vacuum in the intake manifold.ut the MAP sensor doesn't care because it just monitors the absolute pressure inside the intake manifold. On engines with a speed-density electronic fuel injection system, airflow is estimated rather than measured directly with an airflow sensor.
