Global diesel engine market is projected to witness a CAGR of 4.57% during the forecast period 2024-2031, growing from USD 65.96 billion in 2023 to USD 94.31 billion in 2031. Diesel engines have evolved over the years through the addition of digital tools, including remote engine monitoring, predictive services, and over-the-air capabilities. The diesel engine technology has been transformed through emission reduction systems comprising optimized powertrain functionality and aftertreatment systems. Furthermore, the advent of innovative technology such as fuel-agnostic technology has allowed engines to run with various fuel types comprising traditional diesel, natural gas, hydrogen, and many others.
Advances in combustion technology are the most important approaches toward superior performance improvement of diesel engines. The new designs of fuel-agnostic engines introduce features such as DOHC (Dual Overhead Camshaft) designs to improve air intake and combustion efficiency. Torque and overall performance are significantly better than what traditional diesel engines provide. Fuel-agnostic engines are those designed to accept many kinds of fuels without requiring significant changes in the structure of the engine architecture. Hence, companies are adopting this futuristic technology that would go with the rules, regulations, and compliance policies.
For instance, in February 2024, Cummins Inc. announced the launch of an innovative next-generation X15 diesel engine, a part of Cummins HELM 15-liter fuel agnostic platform. The launch is likely to meet aligned 2027 regulations. With higher efficiency, lower emissions, and multiple fuels, the Cummins HELM platforms give end users control of how they navigate their own journeys as part of the energy transition.
Reliable Power Supply and Additional Technologies to Fuel Market Growth
Rising demand for a continuous and uninterrupted power supply is one of the major drivers for the growth of the diesel engine market. Diesel engine manufacturers focus on high reliability, especially in unstable geographical areas with electrical grids and power generation systems. Better performance and supply of fuel have been made possible through the shift from analog to digital controls in diesel engines, increasing combustion efficiency and decreasing pollutants. Digital connections improve overall engine performance and dependability by enabling real-time monitoring and modifications.
Industries such as healthcare, telecommunications, and data centers face significant operational disruptions and financial losses in case of a power outage. Hence, reliable engines are crucial for backup and prime power solutions. Furthermore, advanced technologies, such as emission control technologies like Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR) play a pivotal role in reducing harmful emissions from diesel engines. Technological companies focus on delivering advanced technologies that help the diesel engine’s performance while adding value to the overall market growth.
For instance, in September 2024, in collaboration with Kohler Power Group, PHINIA Inc. introduced the first electronically controlled, low-pressure common rail injection system for small diesel engines utilized in off-highway applications. The CR350 system is a common rail system, made especially for tiny off-highway diesel engines, operable at fuel pressures of up to 350 bar.
Power Performance and Renewable Energy Sources to Fuel Market Dynamics
Diesel engines often become the backup power sources for solar and wind energy systems. It, therefore, proves helpful during low renewable energy generation or grid instability to provide constant power. Heavy-duty after-treatment systems improve the environmental performance of diesel engines by fully treating exhaust fumes before they hit the atmosphere. This ability enables diesel engines to operate with minimal effects on their environment despite providing high power outputs.
Engines are renowned for producing high torque at low RPMs, making them ideal for heavy-duty applications such as construction, agriculture, and transportation. This characteristic allows for efficient hauling and towing capabilities, which is essential in industries requiring reliable power sources. Furthermore, thermal efficiency plays a major role in transforming the diesel engine. Diesel engines typically exhibit thermal efficiencies ranging from 30% to 35% for automotive applications, while low-speed diesel engines, such as those used in marine applications, can exceed 50%. Companies are targeting the factor and trying to maximize brake thermal efficiency.
For instance, in April 2024, Weichai Power Co. Ltd. unveiled the first heavy-duty high-speed diesel engine in the world to have brake thermal efficiency (BTE) above 53%. The business demonstrated a heavy-duty diesel engine with a BTE of 53.09% at the 2024 World Congress on Internal Combustion Engines in Tianjin, China.
Growing Demand for Uninterrupted Industrial Operations to Fuel the Power Generation Segment
Based on the end-use industry, the power generation segment holds a decent share of the global diesel engine market. The growing incidences of power outages and the need for uninterrupted operations in all sectors have increased the demand for diesel generators. Diesel engines can easily ramp up to full capacity and are, hence, ideal for emergency power provision. Industries that require constant power, such as manufacturing and hospitality, deploy diesel generators as a form of protection against potential loss of energy during outages.
The market for diesel power engines is expanding rapidly in emerging nations due in large part to infrastructural developments and rapid industrialization. Strong power generation solutions are increasingly needed as countries such as China and India grow their industrial bases. Heavy equipment used in the mining, manufacturing, and construction industries requires diesel engines to run. Companies target the segment with diesel engines specially designed for power generation usage.
For instance, in March 2023, Moteurs Baudouin launched its new 8M33 Powerkit diesel engine at the Middle East Energy (MEE) Trade Show in Dubai. The newest model in the M33 high-performance series is equipped with a 26.1 L V8 turbo engine. It delivers power outputs between 900 and 1125 kilowatts. The engine operates at speeds between 1500 and 1800 revolutions per minute (rpm). The 8M33 boasts a sleek, power-packed design that employs a high-pressure common rail fuel injection system (ECU models).
Asia-Pacific Accelerates at the Fastest Rate in Diesel Engine Market
Based on the region, Asia-Pacific grows at the fastest growth rate. The region, including countries such as India and China, is expanding its industries while urbanizing different regions. With the growth of industries, the demand for stable power supply in the manufacturing process increases. Diesel engines are preferred due to their strength and good efficiency in applications like heavy machinery and equipment across construction, mining, and manufacturing industries.
Urbanization in Asia-Pacific is on the move, and most people are moving to urban centers. This fuels infrastructure development in the form of roads, bridges, and buildings, constituting a huge demand for diesel-powered construction equipment. Companies functioning in Asia-Pacific collaborate with global giants to deliver engines to Southeast Asia and other markets.
For instance, in May 2024, Cummins Inc. and Isuzu Motor Limited introduced a new 6.7-litre engine, the Isuzu DB6A. This engine, from the strategic partnership between the two companies, marks the first time Cummins will sell in Japan’s on-highway market in its 105-year history. Isuzu and Cummins signed the Isuzu Cummins Powertrain Partnership in May 2019 to realize the efficient development of next-generation powertrains.
