Diesel Common Rail Engine Examination Training Platform

タイトルまたは説明

Based on a real Diesel Common Rail Engine which can operate in all modes such as start, acceleration and deceleration, it visually demonstrates the operating conditions of each system of engine transmission. The testing equipment and meters can test the resistance, voltage, frequency, pulse width and duty ratio. Variation of parameters such as engine speed, injection pressure and intake manifold pressure can be displayed in real time. The computer diagnostic tool can be applied to perform ECU code query, fault code and data stream reading, waveform analysis and executive component test.
This system is equipped with an automatic audible and visual alarm system to avoid long-time inability to start due to not discovering the empty tank after the fuel runs out, as well as to avoid damage to the fuel pump due to unknown cause.
1. The contrast experiment with and without preheating in low-temperature condition is actually performed for the trainee's easy understanding of the effect and importance of preheating in low-temperature condition.
2. The idle running of diesel common rail engine is actually performed for the trainee to observe the operating characteristics of the idle vale of high-pressure pump of the diesel engine at idle during the whole course.
3. Experiment of changes of operating modes such as smooth acceleration, smooth deceleration, sudden acceleration and sudden deceleration can be performed, for the trainee's easy understanding of the operating characteristics of diesel common rail engine.
4. The original car's combination meter (displaying fuel amount, water temperature, preheating, low oil pressure alarm and low charging voltage alarm), digital meter (displaying charging voltage), LED display lamp (displaying idle valve, accumulator valve, and heating plug operating state) and pointer meter (displaying oil pressure) can display all dynamic and static signal parameters of the engine in real time.
5. Fault setting and examination function:
There is a dedicated fault setting and clearing area, with integrated circuit board applied in fault setting. The fault setter of integrated circuit applies **-way high current and a dedicated fault setting and clearing area, with the fault setting system intelligentized. This fault setting system is designed as follows:
(1)Up to *1 individual faults or nearly thousand compound faults can be set, with three functions - closed and open circuit, virtual connection, and short circuit faults.
(2)Functions such as fault presetting, permanent saving, and password locking are available.
(3)Communication Data are separately enveloped for the convenience of maintenance and related examination.
