Indonesia | Pump-Manufacturer Interview

EMAC 2027 Customer Interview Video: Since 2023, EMAC has completed a series of interviews with multiple enterprises from different countries and regions. Most of the videos were shot at the customer companies and factories, and all the evaluations and feedback about EMAC were collected, covering different industries in different countries and regions.

Hydrogen Internal Combustion Engines are Expected to be Widely used

Under the general trend of global energy conservation and emission reduction, it is imperative for the transportation industry to accelerate the process of carbon reduction and decarbonization. As a key factor in promoting energy transformation and upgrading, hydrogen energy has become the focus of competition between commercial vehicle and internal combustion engine companies for diversified technology research and development around hydrogen fuel. Among them, hydrogen internal combustion engines can not only meet emission reduction requirements, but also be comparable to traditional internal combustion engines in terms of operating costs. This unique advantage makes it stand out in the competition of many new energy power technologies and become a preferred solution for many companies.

At present, Europe is making every effort to promote the development of the hydrogen power industry, and many commercial vehicle manufacturers are paying attention to or have begun feasibility studies on hydrogen internal combustion engines. They generally believe that hydrogen internal combustion engines are a preferred solution with relatively low implementation thresholds and cost-effectiveness.

Specifications for Measuring Stator-rotor Air Gap

The stator-rotor air gap is an important parameter of the generator, which can provide an effective reference for mechanical structure design and generator operation. The air gap is a rotating space formed between the rotor and the stator, which is defined by the specifications of the generator parts and mechanical structure equipment. According to the different parameters such as rotor and stator materials, structure and size used in the design and manufacturing process of the generator, a reasonable manufacturing process can be adopted to make the stator-rotor air gap meet the standards of the generator design requirements.

The Harm of Poor Quality Diesel to Diesel Generators

The fuel used by diesel engines is diesel. Its main performance properties include fluidity, atomization, ignition and evaporation, etc. These properties have a great impact on the operation of diesel engines. Poor diesel performance will cause the diesel engine to start difficultly, power reduction, unstable operation, exhaust black smoke, and it is also easy to form carbon deposits on the valves, pistons, and cylinder liners, accelerating the wear of the parts. It can be seen that the performance and quality of diesel have a great impact on the performance of diesel engines. The viscosity and cleanliness of diesel also have a great impact on the operation of diesel engines. Cummins focuses on these two issues in this article.
