IMITATION QUALITY CONTROL SYSTEM OF VEHICLES ENGINE OIL Russian patent published in 2020 - IPC G01M15/04 

FIELD: engine building.

SUBSTANCE: invention relates to engine building, particularly, to internal combustion engine (ICE) test bench with forced ignition with liquid and gaseous fuel. Utility model can be used for visual demonstration of operation of electronic engine control units, and in particular for monitoring control of oil quality in real time. Disclosed is a simulation system for monitoring engine oil quality of vehicles, comprising a crankshaft rpm sensor, a fuel mass flow sensor, a gas pressure sensor in the engine cylinder, a throttle position sensor, a knock sensor, a sensor of angular marks of the crankshaft, an oxygen concentration sensor, an air mass flow sensor and a gas analyzer of harmful emissions in combustion products installed on the tested engine, electronic control unit of the tested engine, an analogue-to-digital converter, a personal computer with a monitor, a model of an electronic unit for controlling the engine mockup, its interface with a personal computer and monitor, simulator of ignition key, generator-simulator of signals of said sensors, switch of said signals, mode setting unit. System is additionally equipped with a motor oil quality control sensor, an engine oil temperature sensor and an electronic unit for evaluating measurement results of said sensors.

EFFECT: invention provides determination of oil quality influence on operational and technical indices of vehicles for diagnostic, research, development and laboratory tests.
