“…Recently, the OBDIII has been developed. Compared to the OBDII, it has faster response times (Yao et al, 2014). Hitachi, Volvo, and some other enterprises have equipped their products with remote control and data transmission systems The data alignment can be used as an effective method to process the data from PEMSs and OBD and to analyze and reduce the errors.…”

The exhaust gas pollutants of the non-road vehicles are harmful to the environment. Many non-road vehicles meet the requirements of the regulations in the laboratory. However, the real-road emissions of such vehicles are sometimes higher. Measuring the real-road emissions of non-road vehicles is very important. The real-road emissions are measured by on-Board Diagnostics (OBD), but there are some problems in the data stability of OBD. The NOx emissions of a bulldozer (a type of China IV non-road vehicle) based on both portable emission measurement system (PEMS) and OBD are studied in this article. Experiments contained three working processes: idle, driving, and operating. The nitrogen oxide (NOx) emissions during operating were highest. The NOx emission characteristics of the bulldozer from PEMS and OBD have the similar variation trends. But there are still some differences, including the NOx emission value and response time. The measurement principles and different sampling points between PEMS and OBD are the main factors. An effective data processing method is introduced to reduce the differences of between the data from PEMS and OBD. Briefly, the NOx emissions of the OBD and PEMS were highly consistent. The OBD is reliable and can be widely used in non-road vehicles.

The article pinpoints main problems in developing intelligent systems for specialist’s tution in motor vehicles expluatation field. These include the lack of means for a comprehensive analysis to detect the violations and causality revealing mechanisms that allow the skills and competencies setup necessary for a specialist. The buildup of stands for troubleshooting on the basis of existing units and parts of vehicles is difficult due to the high cost of equipment, which creates difficulties for creating specialized training laboratories is shown. A new approach proposed that makes it possible to simulate the malfunction detection mode based on a training and research stand. Which makes it possible to apply the following analysis techniques: current indicators results comparison with previously obtained ones, identification and evaluation of various violations on the functioning of the vehicle, as well as detection of bottlenecks and problems. The given examples can serve as a development basis on the of educational and methodological complexes for specialists training in the diagnosis of motor vehicles, as well as new, more complex models for detecting violations. The developed techniques are good in training the road transport specialists in the mode of full-time or distance learning. Furtherness aims to expand the set of indicators identifying a violation of the safety for functioning, as well as the process of their recognition automatization.
