Internal combustion engine, in particular gas engine, for a motor vehicle

摘要

An internal combustion engine, in particular a gas engine, for a motor vehicle, includes a charge air cooler arranged in an air mass flow feed upstream of an apparatus for mixing in fuel, and a measuring device for determining the air mass flow. The measuring device has a sensor system for measuring a pressure loss across the charge air cooler and a processing unit as evaluation unit for calculating the air mass flow at least from the pressure loss which is measured by the sensor system and a charge air cooler model stored in the processing unit. The charge air cooler forms a geometrically constant throttle for the air mass flow which is flowing through.

1. An internal combustion engine for a motor vehicle, comprising:
an air mass flow feed; an apparatus for mixing in fuel; a charge air cooler arranged in said air mass flow feed upstream of said apparatus for mixing fuel, said charge air cooler forming a geometrically constant throttle for an air mass flow flowing therethrough; and a measuring device determining an air mass flow having a first sensor system measuring a pressure loss across said charge air cooler and a processing unit, wherein the processing unit is an evaluation unit configured to calculate the air mass flow flowing through said charge air cooler from at least the pressure loss measured by the first sensor system and a charge air cooler model that is stored in said processing unit.
