2. Mass flow sensor - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_sensor

   A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.

3. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   The engine requires the same mass of fuel in both conditions because the mass of air entering the cylinders is the same. If the throttle is opened all the way in condition 2, the manifold absolute pressure will increase from 50 kPa to nearly 100 kPa (14.5 psi, 29.53 inHG), about equal to the local barometer, which in condition 2 is sea level.

4. Air–fuel ratio - Wikipedia

   en.wikipedia.org/wiki/Air–fuel_ratio

   Air-fuel ratio is the ratio between the mass of air and the mass of fuel in the air-fuel mix at any given moment. The mass is the mass of all constituents that compose the air or fuel, whether they take part in the combustion or not. For example, a calculation of the mass of natural gas as fuel — which often contains carbon dioxide (CO 2 ...

5. Naturally aspirated engine - Wikipedia

   en.wikipedia.org/wiki/Naturally_aspirated_engine

   Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...

6. Lean-burn - Wikipedia

   en.wikipedia.org/wiki/Lean-burn

   The heart of the Mitsubishi's MVV system is the linear air–fuel ratio exhaust gas oxygen sensor. Compared with standard oxygen sensors, which essentially are on-off switches set to a single air/fuel ratio, the lean oxygen sensor is more of a measurement device covering the air/fuel ratio range from about 15:1 to 26:1.

7. Manifold injection - Wikipedia

   en.wikipedia.org/wiki/Manifold_injection

   Intake air throttling changes the amount of air sucked into the engine, which means that if a stoichiometric air-fuel mixture is desired, the amount of injected fuel has to be changed along with the intake air throttling. To do so, manifold injection systems have at least one way to measure the amount of air that is currently being sucked into ...
