14 results about "MAP sensor" patented technology

The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion (see stoichiometry) and influence the advance or retard of ignition timing. A fuel-injected engine may alternatively use a mass airflow sensor (MAF sensor) to detect the intake airflow. A typical naturally aspirated engine configuration employs one or the other, whereas forced induction engines typically use both; a MAF sensor on the charge pipe leading to the throttle body and a MAP sensor on the intake tract pre-turbo.

Engine intake manifold

PCT designated stage expiredWO2025029512A1Exhaust gas recirculationMachines/enginesMechanical engineeringMAP sensor
An intake manifold includes a body member defining an interior chamber having an upper surface and a perimeter wall depending therefrom and extending to a perimeter edge, which extends in a plane. An air intake port extends through the body member and opens into the interior chamber. An EGR tube extends through an EGR tube port in the body member and the EGR tube opens into the interior chamber. A MAP sensor extends through a MAP port in the body member such that an interior portion of the MAP sensor is positioned in the interior chamber and extends from an interior surface of the body member upper surface by a first distance. A shield member includes a shield wall that depends from the interior surface of the upper surface by a distance larger than the first distance and defines a shielded area about the interior portion of the MAP sensor.

Preventing side door accidents using existing time-of-flight (TOF) sensors

Systems and methods for preventing side door accidents using existing time of flight (TOF) sensors include receiving sensor data captured by a sensor system of a vehicle and mapping the sensor data to generate a depth map of a proximity area around the vehicle. Here, the depth map includes objects in the proximity area around the vehicle. The system and method also include determining whether an object in the proximity area is within a region of interest corresponding to the door, and when the object is within the region of interest of the door, generating a notification for a user of the vehicle that alerts the user that the door cannot be opened.

Engine intake manifold

An intake manifold body member has an upper surface with a MAP senor port, an air intake port, and a depending perimeter wall that defines an interior chamber. A MAP sensor port permits a MAP sensor to be inserted by a first distance into the interior chamber defined by the body member. A Map sensor shielding member depends from the body member by a second distance that is greater than the first distance and shields the MAP sensor.
