Intelligent early warning maintenance system for turbocharger

Abstract

The intelligent early warning maintenance system comprises an engine rotating speed detector (1), a turbocharger rotating speed detector (3), an ECU (Electronic Control Unit), an engine torque detector (2) and a three-dimensional data device, the engine rotating speed detector (1) is a rotating speed detection device; the engine torque detector (2) is a torque detection device; the turbocharger rotating speed detector (3) is a rotating speed detection device; the ECU comprises a microprocessor and a memory; the three-dimensional data device comprises three-dimensional data including engine rotating speed data, engine torque data and turbocharger rotating speed data; deviation threshold value data of the rotating speed of the turbocharger are also stored in the ECU; the ECU judges whether the turbocharger operates normally or not according to the three-dimensional data device and data transmitted by the engine rotating speed detector (1) and the engine torque detector (2). Damage to a turbocharger and even damage to an engine can be reduced.

Description

technical field [0001] The invention relates to a turbocharger maintenance system, in particular to an intelligent early warning maintenance system for a turbocharger. Background technique [0002] With the continuous enhancement of the internal combustion engine and the increasingly stringent emission standards, the use of turbocharging technology has become one of the most critical measures to improve engine economy, power and emission standards. With the development of diesel and gasoline engines, as well as the turbocharging technology of unmanned aircraft, the operating speed range of turbochargers is constantly increasing, and the limit speed is constantly increasing. Especially in the use of passenger cars, the working speed of the turbocharger is as high as 200,000 rpm. Working under such harsh conditions, the turbocharger will always be damaged. Damage to the turbocharger will directly cause oil leakage, water leakage and other failures, and even cause the engine t...

Damage to the turbocharger will directly cause oil leakage, water leakage and other failures, and even cause the engine to be scrapped

When a turbocharger failure occurs, it is often when the turbocharger is working. If the turbocharger fails to be detected in time, or even warned that the turbocharger is malfunctioning, and it continues to work, it is likely to cause engine damage.

[0003] At present, the working status of the turbocharger is generally known by measuring the air pressure, air flow, and rotational speed of the turbocharger. This cannot accurately and timely know the turbocharger, which has great delay and inaccuracy, and is fundamentally impossible. less than warning effect
