INTERNAL COMBUSTION ENGINE, IN PARTICULAR GAS ENGINE, FOR MOTOR VEHICLE Russian patent published in 2018 - IPC F02D19/02 F02D41/18 F02M21/02 F02M35/10 

FIELD: internal combustion engines.

SUBSTANCE: invention relates to engine design, in particular, to a device and method for controlling a gas internal combustion engine. Internal combustion engine (1) for a vehicle comprises charge air cooler (6) and a measuring device for determining air mass flow (3). Charge air cooler (6) is located downstream of air mass flow (3) upstream of device (8) for mixing fuel and forms a geometrically constant choke for the passing air mass flow (3). Measuring device for determining air mass flow (3) has sensor system (19, 20) and computing unit (21). Sensor system (19, 20) is designed to measure the pressure loss in charge air cooler (6). Computing unit (21) stores the model of charge air cooler (6). Computing unit (21), based on the model of charge air cooler (6) and the pressure loss measured by sensor system (19, 20), makes it possible to calculate air mass flow (3).

EFFECT: technical result consists in increasing the accuracy and reliability of the air mass flow measurement system.
