Application of Oscilloscopes in Motorcycle Repair

It has always been said that the waveform from the oscilloscope can analyze engine faults, but how can one determine that this motorcycle belongs to a non-Asian electronic fuel injection (EFI) system just from a single waveform image? With the “correct” waveform data, a repair technician can pinpoint the fault within ten minutes, avoiding the precious time wasted on unnecessary disassembly. This “correct” aspect includes two components. On the evening of the 28th at 20:00, we welcome you to join our QQ group 55507702 for a voice class to share the exciting aspects of waveform repair. What you think is not what you think; technology has exceeded our imagination.

Final training notice for EFI technology (oscilloscope/diagnostic instrument) for 2017.

According to the work arrangements for 2017 and 2018, the originally planned registration for the last technical training class of 2017, scheduled for the end of 2017, has been changed to mid-March 2018 due to the upcoming Spring Festival and the difficulties in purchasing tickets for everyone.

The original fee standard is 600 yuan for accommodation and meals.

The training fee for 2017 was 4000 yuan, including 3 (sets) of materials + 2 (sets) as a gift.

The training fee for 2018 is 5000 yuan, including 3 (sets) of materials.

Those who wish to participate in this training should register effectively before January 31, 2018, to continue enjoying the 2017 fee and material standards. Registrations after January 31, 2018, will follow the 2018 fee and material standards. Effective registration is based on payment.

With the further implementation of national environmental protection regulations, electronic fuel injection systems will be fully applied to domestic motorcycles. This will fundamentally change the diagnosis and repair methods in the repair industry. The current replacement comparison method will become increasingly difficult, even unsustainable; using diagnostic repair tools is inevitable. Diagnostic equipment for EFI systems and oscilloscopes, which have never been used in past repairs, will become standard configurations for repairs in the EFI era.

Diagnostic equipment indicates the fault range, while oscilloscopes display the faulty components. Data streams and waveform patterns can be dazzling, not to mention how to read and interpret the data from these devices, which has become another new challenge and professional difficulty faced by motorcycle repair technicians.

We know that diagnostic equipment can display various states of the vehicle’s EFI system, but not every state will indicate that a problem exists (such as intermittent faults), which is mainly restricted by the design of the control program for the EFI system.

For example, if the basic position of the throttle position sensor is 5%, it is still an EFI system fault, but no EFI diagnostic equipment will indicate that “a fault exists.” How to deal with such situations?

Oscilloscope equipment is known as the ultimate weapon in EFI repair work. However, the relatively complex interface operation and waveform reading and analysis skills have deterred many repair technicians who wish to use this equipment. The basic entry difficulty of oscilloscopes is relatively high, which is a significant headache in the industry. This is also an important reason why the diagnostic technology of oscilloscopes has not been popularized for many years in the EFI era of the automotive industry.

In view of this, Jinan Che Shen Motorcycle (Motorcycle Friends World) invites Shanghai Hexun Electromechanical Engineering Co., Ltd., a member unit of the All-China Federation of Industry and Commerce Motorcycle Parts and Supplies Industry Association with technical service qualifications in the automotive and motorcycle industry, to jointly hold a technical training workshop on “Application of Oscilloscope Equipment and Diagnostic Equipment in Motorcycle EFI Systems” for domestic motorcycle repair technicians to cope with new technologies. Specific learning content can be found in Attachment 1.

To ensure the quality of learning, the training location is in Hefei, Anhui. Registration is now open, and students are requested to bring their own oscilloscope and EFI diagnostic instrument for on-site practical explanations.

Disabled individuals with relevant certificates from the civil affairs department will have their tuition waived, only paying for accommodation and meals, with the proportion of disabled individuals in each class not exceeding 40% (calculated based on the order of registration).

To ensure the effectiveness of learning, the organizer will also provide three months of free online remote technical guidance service after the training class ends. For those with a poor foundation in motorcycle diagnostic and repair skills, a certain proportion of tuition-free re-learning slots will be provided in subsequent classes. This will enable all participants to truly apply what they learn and effectively solve problems encountered in their work, reshaping the social status of the industry and gaining the respect it deserves.
