A Counterattack by Internal Combustion Engines Amidst the EV Wave? April 10, 2026, marked another new chapter in the history of the automotive industry. Global automotive supplier Bosch unveiled its 'Rapid Catalyst Heater Burner' technology, showcasing the evolution of internal combustion engines (ICEs) in addressing environmental concerns. This technology focuses on dramatically reducing 'cold start' emissions, a major problem in conventional internal combustion engine vehicles. In an era where electric vehicles (EVs) are becoming mainstream, why has Bosch concentrated on eco-friendly technology for ICEs? This might be more than just a technological advancement; it could be a significant signal offering a glimpse into the present and future of the automotive industry. The 'cold start' issue has long been identified as a critical challenge for ICE vehicles. Harmful gases emitted immediately after vehicle ignition, when the engine has not yet reached optimal temperature, are a major cause of air pollution. Typically, ICE vehicles have low emission purification performance until the catalytic converter heats up sufficiently after startup, making them a primary contributor to environmental pollution. Emissions generated during this initial phase account for a significant portion of total emissions over an entire driving cycle, posing an even more severe problem in urban driving patterns involving frequent short trips. Bosch's Rapid Catalyst Heater Burner offers a powerful solution to this issue. The new system aims to effectively reduce harmful emissions within just a few seconds by rapidly heating the catalytic converter immediately after the car starts. As the engine begins to operate, it brings the catalytic converter to its operating temperature within seconds, instantly optimizing emission purification performance. This dramatically reduces the large volume of unpurified emissions that occur during the initial startup phase. Specifically, it can significantly cut emissions during short-distance travel, such as urban driving, and is expected to have a direct impact on improving air quality. There have been several technological solutions in the past aimed at reducing harmful gases from gasoline vehicles. However, most of the solutions proposed by these technologies had limitations in terms of complexity and cost, failing to achieve widespread market adoption. Attempts were made to improve the performance of catalytic converters themselves or shorten engine warm-up times, but these were insufficient to fundamentally resolve the cold start issue. Bosch's new system is applicable to existing ICE vehicles and is expected to show high effectiveness in terms of emissions reduction. So, in an era transitioning to electric vehicles, why should we pay attention to ICE technology? The answer to this question lies in the realistic pace of transition. Considering the reality that ICE vehicles will remain on the roads for a considerable period before a complete transition to EVs occurs, improving the environmental performance of existing vehicles is a crucial task. The transition process may take longer than expected due to the complex interplay of various factors, including EV infrastructure development, battery technology improvements, and shifts in consumer perception. During this transitional period, hundreds of millions of ICE vehicles will continue to operate, and reducing their emissions can bring immediate environmental benefits. Rapid Catalyst Heater Burner Finds a Solution to Air Pollution The importance of this technology is clear when examining recent changes in the automotive market. While major global automakers are making massive investments in the EV market, ICE vehicles still account for a significant share of the market. In developing countries or regions where charging infrastructure is not fully established, demand for ICE vehicles is expected to persist for some time. Furthermore, the transition to EVs is likely to proceed more slowly in the commercial vehicle and long-haul transport sectors. Therefore, technology that improves the environmental performance of ICEs is not merely prolonging an old technology but can be a practical solution to ongoing environmental problems. Bosch expects this technology to meet increasingly stringent global emission regulations and contribute to improving air quality. Governments worldwide are implementing increasingly strict environmental regulations to address air pollution, and automakers are exploring various technological solutions to meet these requirements. The Rapid Catalyst Heater Burner is highly likely to become one of the key technologies for complying with these regulations. Particularly, if it offers high compatibility with existing production lines, it could provide a way for automakers to meet environmental regulations without significant cost burdens. Of course, not all technologies are without drawbacks. The Rapid Catalyst Heater Burner technology
