DOC・DPF市場：タイプ別、用途別、地域別、2025-2033年

DOC・DPFの市場の世界市場規模は2024年に216億米ドルに達しました。今後、IMARC Groupは、2033年までに市場は362億米ドルに達し、2025～2033年の成長率（CAGR）は5.58%になると予測しています。環境意識の高まり、広範な研究開発活動、DOC・DPFの普及が市場を牽引する主な要因です。

DOC（ディーゼル酸化触媒）とは、排気中の酸素を利用して一酸化炭素（CO）と炭化水素を二酸化炭素（CO2）と水に還元・変換するよう特別に設計された触媒後処理コンバーターのことです。一方、DPF（ディーゼル微粒子フィルター）は、排気中の煤を物理的に捕捉・貯蔵し、自動車の排出ガスを削減するためのコンポーネントです。これらの装置はハニカムセラミックフィルターで構成されており、ディーゼルエンジンで特に使用され、触媒を通過する気相排出を減少させます。DOC・DPFは、存在するカーボンの量を測定してその質を示し、エンジン性能を向上させ、燃費を最適化し、窒素酸化物（NOx）の排出を削減するのに役立ちます。これらの特性に基づいて、DOC・DPFは小型・中型・大型商用車（HCV）や乗用車に広く使用され、車両効率を高めています。

DOC・DPFの市場動向：

自動車産業におけるDOC・DPFの広範な応用は、市場成長を促進する重要な要因の一つです。これに伴い、ディーゼル車への需要が高まっていることも、成長を促す大きな要因となっています。さらに、持続可能な開発への注目の高まりと、環境保全に関する政府の厳しい規制が市場成長に寄与しています。各国政府も環境に配慮した取り組みを進めており、これが市場成長に寄与しています。排出ガス監視を担当する規制当局の設置が各国で増加していることも、市場の成長を後押ししています。これに加えて、製品性能を向上させるためのメーカーによる大幅な技術進歩や、低温でNOx排出を制御・削減する選択的触媒還元（SCR）システムの登場が、市場成長に寄与しています。これとは別に、バッテリー式電気自動車（EV）の利用という新たな動向が市場成長を後押ししています。これに加えて、多様でより効果的な製品バリエーションを開発するために、OEMと複数の大手企業が戦略的に協力していることも、市場の成長を後押ししています。その他の要因としては、広範な研究開発（R&D）活動や、DOCおよびDPFユーザーの必要なニーズに応えるアフターマーケットサプライヤーの増加などがあり、市場の見通しはさらに明るいものとなっています。

The global DOC and DPF market size reached USD 21.6 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 36.2 Billion by 2033, exhibiting a growth rate (CAGR) of 5.58% during 2025-2033. Rising environmental consciousness, extensive research and development (R&D) activities, and the widespread application of DOC and DPF represent some of the key factors driving the market.

A diesel oxidation catalyst (DOC) refers to a catalytic after-treatment converter specially designed to reduce and transform carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water by using oxygen in the exhaust. Meanwhile, a diesel particulate filter (DPF) represents a component that helps physically capture and store exhaust soot to reduce automobile emissions. These devices are structured in honeycomb ceramic filters and are explicitly used in diesel engines to reduce gas-phase emissions flowing through the catalysts. DOC and DPF help measure the amount of carbon present and indicate its quality, improve the engine performance, optimize the fuel economy, and reduce nitrogen oxides (NOx) emissions. Based on these properties, DOC and DPF are extensively used in light, medium, and heavy commercial vehicles (HCVs) and passenger cars to enhance vehicle efficiency.

DOC and DPF Market Trends:

The widespread application of DOC and DPF in the automotive industry represents one of the key factors driving the market growth. In line with this, the rising demand for diesel vehicles is acting as another major growth-inducing factor. Moreover, an enhanced focus on sustainable development and stringent governmental regulations regarding environmental conservation are contributing to the market growth. Governments of various countries are also undertaking several green initiatives, which is contributing to the market growth. Increasing establishments of regulatory authorities in various countries responsible for emission monitoring are favorable supporting the market growth. In addition to this, significant technological advancements by manufacturers to improve the products performance and the advent of a selective catalytic reduction (SCR) system for controlling and reducing NOx emissions at lower temperatures are contributing to the market growth. Apart from this, the emerging trend of utilizing battery electric vehicles (EVs) are driving the market growth. This, along with strategic collaborations amongst original equipment manufacturers (OEMs) and several leading players to engineer diverse and more effective product variants are driving the market toward growth. Other factors, such as extensive research and development (R&D) activities and an increasing number of aftermarket suppliers catering to the required needs of DOC and DPF users, are creating a positive outlook for the market further.
