Industrial power supplies are power products specially designed and produced for a certain industrial production industry. For industrial power supplies, absolute balance of electronics characteristics is not the main focus. Different industrial applications focus on different specific electronics index, some focus on the stability of the power supply output voltage or current, but the ripple is not the key judging criteria; some industrial applications have customized requirements for power supplies, such as adding time control, adding pulse functions, adding multiple outputs, etc. At the same time, it is necessary to consider the cost requirements of large-scale purchases of industrial applications, so for industrial power supplies, Application adaptability, Long-term operating Reliability and Reasonable cost control are the main points of attention for industrial power supplies.

In the current automotive landscape, as fuel economy and environmental protection standards become increasingly stringent, automakers are turning to innovative technologies to meet the urgent demands for energy efficiency, emission reduction, and consumption control. For traditional vehicles, adopting clean fuels, lightweight designs, improving engine and drive system efficiency, and reducing aerodynamic resistance remain the most effective strategies. These efforts have become a focal point in automotive technology innovation. Meanwhile, new energy vehicles and all-aluminum body structures have emerged as key trends in the industry.
Despite these advancements, the internal combustion engine still dominates the automotive market. Following the widespread adoption of turbocharging, the industry is now looking forward to new technologies that can further enhance the efficiency of conventional engines. Recently, Delphi, in collaboration with scientists from Silicon Valley-based Tula, introduced a groundbreaking innovation called "Dynamic Skip Fire" (DSF) technology. This technology enhances the performance of traditional power systems and opens up new possibilities for improving the energy efficiency of internal combustion engines to meet evolving regulatory requirements.
DSF, or "Engine Dynamic Miniaturization," has been fully launched in the Chinese market. Hu Nan, General Manager of the Asia-Pacific region for Delphi Powertrain's Gasoline Engine Management System, emphasized the importance of DSF in a recent interview with Gasshi Automotive: “The internal combustion engine will continue to be the dominant power source in the automotive industry for the next 30 years. DSF is a key strategic initiative from Delphi headquarters to China. We aim to promote this technology in the Chinese market to help customers meet stricter fuel consumption regulations and develop vehicles that comply with national standards.â€
Currently, SUVs account for over 30% of the Chinese auto market, and engines larger than 1.6L make up more than 60% of the market. According to Hu Nan, this reflects consumer preferences for larger vehicles with powerful engines. DSF offers an ideal solution to meet tighter emissions and fuel efficiency regulations by enabling large-displacement engines to function more efficiently, mimicking the performance of smaller engines while maintaining power output.
DSF, known as Dynamic Skip Fire, is the first fully variable cylinder deactivation technology in the industry. It can be applied not only to multi-cylinder engines but also to 4-cylinder engines. According to testing data, a 4-cylinder engine equipped with DSF can save between 6% and 8% in fuel consumption under different driving cycles, significantly improving fuel efficiency and reducing COâ‚‚ emissions by at least 50%. Unlike traditional cylinder deactivation systems, which operate under fixed conditions, DSF provides real-time decision-making based on vehicle demand, making it far more efficient.
For example, when a vehicle requires 20 Nm of torque at low speeds, traditional systems may either underperform or oversupply power. DSF, however, calculates the exact torque needed and dynamically adjusts the number of active cylinders to match the demand precisely, ensuring smooth and responsive performance.
At each ignition cycle, the DSF system decides in real time which cylinders to ignite. This critical component of the engine control strategy requires careful optimization of valve activation, throttle opening, and ignition timing. The choice of which cylinders to deactivate is also based on avoiding engine resonance and achieving smoother operation.
By determining whether to ignite each cylinder in every cycle, DSF pushes cylinder deactivation technology to its theoretical limits. In the future, it could also help regulate exhaust oxygen content, reduce aftertreatment system load, improve Miller cycle efficiency, and even support advanced combustion techniques like gasoline compression ignition. This gives engineers greater flexibility in optimizing combustion strategies.
In October 2016, Delphi and Tula demonstrated a 1.8L turbocharged GDi car equipped with DSF technology at the Aachen Colloquium in Germany. The system was later introduced to the Chinese market. During a test drive of a 1.8L Volkswagen Jetta with DSF, the dynamic cylinder deactivation process felt seamless, with no noticeable interruptions, enhancing both comfort and noise reduction.
The DSF system involves two main components: the fuel-saving control valve, acting as the system controller, and the rocker arm, which functions as the actuator for cylinder deactivation. When hydraulic pressure is applied, the lock pin opens, allowing the rocker arm to move freely and close the valve. When the pressure is released, the spring resets the lock pin, and the rocker arm returns to its normal position, reopening the valve.
This process enables precise control over engine torque demand, allowing cylinders to be deactivated flexibly based on actual needs, resulting in improved fuel efficiency.
DSF technology allows the engine to operate more efficiently by reducing the number of active cylinders while keeping the throttle fully open, thus improving combustion efficiency and minimizing pumping losses. For smaller engines, the challenge lies in maintaining performance when some cylinders are not firing. However, Delphi and Tula have solved this issue, making DSF compatible with all common powertrain configurations.
When combined with other Delphi technologies, such as the 48V mild hybrid system, DSF can deliver even greater benefits. The 48V system alone can reduce COâ‚‚ emissions and fuel consumption by over 10%, and when paired with DSF, the savings increase to 20%. Xu Xiangdong, Engineering Director for Delphi Powertrain Systems Division in the Asia-Pacific region, explained: “DSF is an innovative approach to traditional internal combustion engines. When combined with the 48V system, the two technologies can work together without increasing hardware costs, achieving a synergistic effect of 1+1>2. Depending on the OEM’s technical route, we provide customized solutions.â€
While turbocharging focuses on boosting the performance of small engines, DSF supports dynamic miniaturization when needed. These two technologies complement each other, meeting the diverse demands of the market without replacing one another.
Xu also highlighted the growing importance of turbocharging in the market and the role of DSF in helping manufacturers meet fuel efficiency targets. He noted that many OEMs face challenges in balancing performance and compliance, particularly with larger engines. DSF helps address this by enabling high-displacement engines to operate more efficiently, meeting regulatory requirements without sacrificing power.
Looking ahead, Delphi aims to launch mass production projects using DSF technology in China by the end of 2020, aligning with the country’s target for new passenger cars to achieve an average fuel consumption of 5 L/100 km. The company is working closely with production partners to meet these goals and ensure the successful implementation of DSF technology in the Chinese market.
